6 Introduction

The domo ClearCam is a tactical digital video transmitter system and is part of the domo SOLO4 and SOLO2 product family. The SOLO4 and SOLO2 product range enables the user to build simple wireless digital microwave video systems. The domo SOLO4 and SOLO2 products have been designed to provide rugged point-to-point links for high quality full frame rate video, and audio, even in non line of sight and urban environments.

Existing analogue systems suffer from impairments such as video noise, loss of colour information and poor image quality when line of sight cannot be maintained. PC platforms and solutions based on wireless internet standards including WiFi deliver poor quality video, as well as poor range capability.

The domo SOLO4 and SOLO2 system is a digital system that uses the COFDM modulation technique, which effectively eliminates the problems caused by multipath and reflections.

The SOLO product range allows law enforcement, surveillance and emergency service communities to now receive the highest quality video images, in real time, direct from personnel, buildings and vehicles.

The domo SOLO2 system employs the DVB-T 2K carrier COFDM technology.

The domo SOLO4 system employs a revolutionary narrow band 2.5MHz COFDM technology which demonstrates better propagation for longer range links, and extra bandwidth efficiency. The domo SOLO4 system can also be upgraded to include a 1.25MHz COFDM modulation and MPEG4 compression for excellent range performance.

The ClearCam is a rugged PTZ camera designed specifically for rapid deployment. The system incorporates a periscope camera, digital video transmitter, telemetry receiver and battery technology inside a weatherproof package for long term outdoor deployment.

The ClearCam is used in conjunction with the MicroVue Commander to provide a complete digital surveillance link. The ClearCam differs from other domo Solo4Tx products in its return control channel built into the system.

The ClearCam chassis is designed with the intent of meeting IP66 and supplied with a variety of mounting options. The integral periscope camera can be detached from the base for maximum deployment flexibility. It is supplied with DC and internal battery power.

The domo narrow bandwidth modulation offers unprecedented spectrum efficiency, while also increasing the system sensitivity and therefore range.

Security of transmission is ensured by the use of Standard ABS encryption or for greater security the optional AES128- or 256-bit encryption algorithms.

For detail on the MicroVue Commander operation, please refer to the ‘MicroVue and MicroVue Commander User Manual’.

9.3 Basic Operation

Powering on the domo ClearCam

The ClearCam has two power supply options

• Internal Batteries

• External DC Input

The unit is powered on by latching the green master power switch into the depressed ON position. The status screen will briefly display the domo logo if power is On and there is power remaining in the batteries. Note that if the battery is completely exhausted the screen will not light.

Internal Batteries

The ClearCam will automatically switch to using the internal battery supply when the DC input is not connected to a valid supply.

The internal batteries are charged automatically when a valid supply is connected to the external DC input.

Fully charged batteries will power the ClearCam for about 7h30min in continuous 100mW mode, and 3h40min in continuous 1W mode.

The battery life can be extended by employing the Sleep Mode options of the unit. See paragraph ‘Sleep modes’ for more information.

See the paragraph ‘Charging the domo ClearCam’ for charging information.

External DC Input

The domo ClearCam can be powered from an external DC source such as a battery, by connecting the DC connector in the external connector cabinet to a DC source with the following characteristics.

Voltage: 11 to 16V

Current: max (when charging) 6A (at 12V)

Typical (when charged) 3A (at 12V)

Charging the domo ClearCam

The domo ClearCam internal batteries are automatically charged when the unit is connected to an external DC source.

The time required to fully charge the batteries from fully flat is as follows.

Charging when ClearCam powered off: Approximately 1.5 hours

Charging when ClearCam powered on: Approximately 3 hours

Note: When the Clearcam has exhausted the battery and a new power source, such as a new battery the POWER switch MUST be switched OFF and ON to restart the unit.

This requirement stops the unit ‘cycling’ on and off when the battery is approaching a flat condition.

14

Understanding the user interface

There are five buttons on the front of the ClearCam, as shown in the figures below. The functionality is outlined in Table 2.

Figure 2 ClearCam user interface

Pressing this button gives the user access to the general status

information of the unit. The following parameters will be displayed

in order:

• Config: Config number currently loaded from memory.

Eight configurations can be stored in the unit’s memory.

• Battery life: Estimated remaining battery life of

ClearCam

• Link in: Frequency and link quality of ClearCam telemetry

receiver. The link status is rated on a five star basis. 0

stars = no link; 5 stars = excellent link.

• Link out: Frequency and link quality of the ClearCam

video transmitter.

The link status is rated on a five star basis. 0 stars = no

pressed.

Note 1: The Status information related to Link Out is sent via the telemetry link into ClearCam. Hence, with no link in, no status information is available about the Link Out.

Note 2: It is possible to control up to 15 different cameras with one MicroVue Commander. To facilitate this, the ClearCam only accepts PTZ commands if the Camera Control Address number is the same as on the Commander. See Section ‘MicroVue Commander Basic Operation’ for more information.

Changing Configuration on the domo ClearCam

The ClearCam contains both a video transmitter and telemetry receiver.

To simplify the operation of the domo ClearCam, users can pre-program eight ‘User Configurations’ for both the ClearCam transmitter and receiver. In their simplest form these can be thought of in the traditional sense as eight frequency channels. However, the User Configurations actually store all the parameters of the ClearCam and not just its frequency.

When changing the ClearCam config as described in Table 2, both the transmitter and receiver confgs are changed at the same time.

The currently loaded User Configuration can be viewed by pressing the STATUS button.

The default User Configurations (values of parameters which the units are shipped with) are described in Section 14 at the end of the user guide.

See the advanced Section 10 of the user guide for more information on how to edit the parameters inside the user configurations.

Deploying and Operating the domo ClearCam

The domo ClearCam is a tactical digital video transmitter, and the following guidelines should be employed when using the equipment.

• Connect the L- or S-band transmit antenna (TNC connector) to RF OUT, and UHF receive antenna (BNC connector) to RF IN on the base of the ClearCam.

• Connect the Camera to the base via the camera cable. Note the genders on the cable.

• Either coil the short camera cable into the camera base and slot the camera base into the chassis, or mount it elsewhere with the long camera cable.

16

• Connect the telemetry transmit antenna to the SMA connector on the lid of the MicroVue Commander.

• Switch on both the ClearCam and MicroVue Commander and make sure they are on the same config.

• Depending on the RF environment (line of sight or non line of sight) and the power of the transmitter (100mW or 1W), the ClearCam will operate at a range typically 300m to 1km from the Commander.

• To prevent damage to the MicroVue Commander, it should not be operated too close (within 5m typically, further if the ClearCam is transmitting 1W in power) of the ClearCam.

Note: Connect antennas BEFORE powering on unit.

Damage may occur if the transmitter drives 1W output power into no load

External Connections on the domo ClearCam

The side connector panel of the ClearCam incorporates a number of external connections using the Amphenol 62GB range, as shown in Figure 3.

Figure 3 ClearCam connector panel

• 12V DC for external DC input. Source must be capable of 12V 8A.

• Control, for connection to a PC control application.

• Sensors, for the connection of trigger input, e.g. Passive Infrared sensors.

• Audio input and output.

• Camera 2, for a second camera input to the unit.

17

These connectors are completely waterproof when mated with their cables or the supplied dust caps. However, they are not waterproof when unmated as in Figure 3.

The cables supplied with the unit include a 12V DC power cable and PC control cable.

The connector part numbers and pin-outs are supplied in the section ‘Connector Pin Outs’.

Connecting to PC Control

The domo ClearCam can be controlled from a PC with the domo Control Application, via RS-232.

Connect a domo control cable to any serial port on the PC and plug the Amphenol connector into the side of the ClearCam. Start the PC control application.

It should now connect to the unit while saying “Reading transmitter settings” and “Reading receiver settings”, enabling the user to edit these parameters. See the ‘Control Protocol’ section for details of the protocol, baud rates etc.

18

10 Advanced Operation

The following section should be read by users concerned with the more advanced operation of the domo MicroVue. Topics covered include:

• Battery management with sleep modes

• Connecting the PC Controller.

10.1 Battery Management with Sleep Modes

The battery life of the ClearCam is about 3h40min in continuous 1W mode, and 7h30min in continuous 100mW mode. This can be extended through the use of sleep modes and sleep timeouts.

Sleep mode 1

When the unit is put into Sleep mode 1, the video transmitter will be switched into standby mode after a set number of minutes of trigger inactivity. This drops the power consumption to 34% of the power needed in continuous 100mW mode.

The unit can be woken up from Sleep mode 1 by a trigger event, by remotely setting sleep to OFF on the MicroVue Commander, or by setting sleep to OFF on the PC control application.

Sleep mode 2

When the unit is put into Sleep mode 2, both the video transmitter and telemetry receiver will be switched into standby mode after a set number of minutes of trigger inactivity. This drops the power consumption to 18% of the power needed in continuous 100mW mode and provides the longest possible battery life.

The unit can be woken up from Sleep mode 2 by a trigger event, or by setting sleep to OFF in the PC control application. NOTE: The MicroVue Commander can not be used to wake a unit up from Sleep mode 2 remotely.

Sleep timeout

The number of minutes of no trigger activity before sleep timeout is set in the PC control application and can be in the range of 1 to 9 minutes.

Wake up

Upon the occurance of trigger activity, or by setting Sleep mode to OFF in the PC control application, the ClearCam will wake up both the transmitter and receiver.

Wake up time is approximately 4 seconds.

See the section ’ ClearCam control application: System settings’ for how to set up the sleep modes on the PC control application.

19

10.2 Connecting the PC Controller

Advanced control of the ClearCam system is available by using the PC control application. This can be achieved by connecting a PC RS-232 port to the 3-pin Amphenol control port.

Connecting to the PC

Installation of the control program is as simple as copying it from the CD to a suitable location on the PC. No install shield routine is launched. Note that the controllers generate their own log and initialisation files, so it is best to create a dedicated directory for these applications, perhaps with links to the applications from the desktop of the PC.

Use the supplied cables to connect the chosen COM port(s) of the PC to unit(s) to be configured.

Launch each application in turn by double clicking or using the run command.

Connection with a SOLO product should be automatic, but the user can force selection of the correct COM port using the drop down, followed by the “Connect” button.

Errors such as the following may appear during the connection process if the PC is unable to automatically ascertain which unit is connected to which COM port.

• Error attempting to read invalid address

• Error has occurred during polling, polling has been disabled

For both controllers, changes can be made to the unit configuration using the drop down and data entry fields.

Changes are only applied to the unit when the “Apply” button is clicked.

Current values, as running in the unit, can be read using the “Refresh” button.

Parameters that are status information only appear in greyed in the application.

Further engineering and configuration controls can be found within the “Options” and “File” drop down menus in the application title bars.

Understanding configs and how to modify them

domo ClearCam features eight user selectable and programmable configurations, relating to both the transmitter and receiver in the unit.

The transmitter and receiver have separate tabs and are set up individually as shown in

Figure 4, each having 8 configs.

These 8 configs allow the user to store useful default channels for quick selection. After restoring defaults and loading the supplied config set, all 8 configurations are set to the values which are listed in the Section 14 of the handbook.

20

The current config is defined as the number of the currently selected configuration 1 to 8. The current config can be changed by selecting a different config tab.

Upon exiting the control application, the transmitter is set to the same config number as the receiver. Further, loading a config on ClearCam with the CONFIG button will load that config number on both the transmitter and receiver.

Output Frequency (MHz)

The transmit frequency can be changed by entering the new desired frequency in this field. Values outside the range supported by a particular transmitter type will be rounded to the highest of lowest supported frequency as appropriate.

The transmit frequency can be set in step sizes of 250kHz.

Bandwidth Mode

The Bandwidth Mode switches the unit between either domo Narrowband (2.5MHz or 1.25MHz channel bandwidths) or DVB-T 8MHz bandwidth. To select 6MHz and 7MHz DVB-T modes the user must first click on ‘Advanced’ to enter the Advanced setting page.

Default Transmit Mode

In Narrowband the user has the following pre-defined modes available from the main window. Note that the Ultra Long Range Mode is only available to users who have purchased the SOLO4TXUP option (1.25MHz and MPEG-4 modes). The user can of course define their own specific FEC, bandwidth and modulation requirements from the ‘Advanced’ page.

Ultra Long Range: 1.25MHz QPSK FEC 1/3 (optional)

Long Range: 2.5MHz QPSK FEC 1/3

Medium Range: 2.5MHz QPSK FEC 2/3

Short Range: 2.5MHz 16QAM FEC 2/3

In DVB-T the available modes are

QPSK ½ FEC 8MHz 1/32 Guard Interval

QPSK ¾ FEC 8MHz 1/32 Guard Interval

16QAM ½ FEC 8MHz 1/32 Guard Interval

Audio

Output Frequency (MHz)

The transmit frequency can be changed by entering the new desired frequency in this field. Values outside the range supported by a particular transmitter type will be rounded to the highest of lowest supported frequency as appropriate.

The transmit frequency can be set in step sizes of 250kHz.

Modulation Bandwidth

For the SOLO2 transmitter products, the modulation bandwidths 8, 7 or 6MHz can be selected.

23

For the SOLO4 transmitter products, the modulation bandwidths 8, 7, 6 or 2.5MHz can be selected. If the Ultra Narrow band upgrade has been purchased the 1.25MHz will also be available to select.

The normal mode of operation is 2.5MHz.

Modulation Output

This control is used to turn on and off the RF output.

Narrow Band FEC

This option applies to SOLO4 transmitters only. The default FEC is 2/3. Improved range operation can be achieved by selecting FEC 1/3. FEC 1/3 will improve signal range by 3dB. However, FEC 1/3 reduces link capacity to 1.2Mb/s therefore reducing picture quality.

FEC Link Bitrate Sensitivity

2/3 2.4Mb/s -99dBm

1/3 1.2Mb/s -102dBm

Narrow Band Guard Interval

This option applies to SOLO4 transmitters only. The Guard Interval defaults to 1/16. Interval 1/8 is also available for very long range (aircraft downlinks) applications.

Narrow Band Modulation

This option applies to SOLO4 transmitters only. The COFDM mode can be changed between QPSK and 16QAM. QPSK is the default mode and will give the strongest most rugged RF link performance. Selecting 16QAM reduces the link performance by 5dB but improves the link data throughput, giving significantly better video quality.

Note: The terminology DVB-T refers to the 8,7,6MHz wide bandwidth modulation employed in the SOLO2 products. The SOLO4 product is also capable of DVB-T, but this mode is not recommended for normal operation

DVB-T Service Name

Applicable in DVB-T mode only, defaults to Unit 1. This should not be changed in normal operation

DVB-T FEC

Applicable in DVB-T mode only, the default FEC is ½. Other FEC rates will all reduce the range of the product, but will improve image quality and capacity of the link.

24

DVB-T Guard Interval

Applicable in DVB-T mode only. The Guard Interval defaults to 1/32. Other guard intervals such as 1/16 or 1/8 are available for very long range (aircraft downlinks) applications.

DVB-T Modulation

Applicable in DVB-T mode only, the COFDM mode can be changed between QPSK, 16QAM and 64QAM. QPSK is the default mode and will give the strongest most rugged RF link performance. Selecting 16QAM reduces the link performance by 5dB but improves the link data throughput, giving significantly better video quality.

Output Attenuation

This control can be used to make minor adjustments to the output power level, but in normal operation should be disregarded.

Video Input

This control is used to select the video input standard. Options are composite video (PAL, and NTSC both with and without 7.5 IRE pedestal), S-video (PAL and NTSC) and SDI (not applicable to ClearCam).

MPEG Mode

The default encoding mode is MPEG2, however for SOLO4 products if the Ultra Narrow Band upgrade has been purchased, then MPEG4 will also be available. It is recommended that MPEG4 be employed when the unit is operating at low bitrates (2.5MHz bandwidth FEC1/3 or 1.25MHz bandwidth FEC1/3).

MPEG4 Encoding Mode

This option is only available on SOLO4 products installed with the Ultra Narrow Band Upgrade. This defaults to low delay interlace. Other modes are available but advice should be sought from domo before selection.

MPEG4 Frame Rate

This option is only available on SOLO4 products installed with the Ultra Narrow Band Upgrade. This option allows the user to select lower frame rate encoding (1/2 frame rate, ¼, 1/8 etc) It is recommended that MPEG4 reduced frame rates be employed when the unit is operating at low bitrates (1.25MHz bandwidth FEC1/3).

25

Horizontal resolution

The video coding resolution can be selected from 704, 528, 480 and 352 pixels. Changing the horizontal resolution to lower values will make the coded picture softer.

Care should be taken to match the horizontal resolution to the resolution of the camera connected to the transmitter; this will give best image results.

Audio Encoder

The Audio can be turned on and off with this control. Audio is OFF by default, but there are several audio modes that vary from very high quality to speech grade that can be selected with this control. Enabling audio will degrade the video quality, because some of the available data capacity is diverted away from video to audio. Selecting high fidelity audio modes will degrade the video quality more than lower fidelity audio modes.

Audio Input Level

This control is used to define the audio gain to be applied to the audio input signal. 0dB is used for line level audio and various options up to 48dB of gain can be applied for microphone inputs.

Unit Name

This field allows the user to enter an identifier for the service that they wish to transmit. This must match that selected at the receiver for the service to be decoded. The unit name can be constructed of any eight ASCII characters.

Data

With this ON / OFF control the user can select whether the transmitter passes serial RS232 data across the RF link to the receiver.

Data Baud Rate

This field is used to select the baud rate of any RS232 serial data component to be passed from the transmitter to the receiver across the RF link.

Current Config

This field reports the last loaded configuration number. Note that for the SOLO transmitter, changes applied after the configuration has been loaded are saved immediately into the current configuration.

26

Scrambling

If the AES scrambling option has been purchased for the SOLO2 or SOLO4 system in use, then it is possible to encrypt the link. Scrambling must be enabled at the transmitter by selecting either AES128 or AES 256 in the scrambling field. At this point the user will need to ensure that the correct key is in use and this is done by using Options / Write AES Key.

The key is a 128bit key for AES128 and a 256bit key for AES256 and is entered as either 32 or 64 ASCII hexadecimal characters (0..F).

Video Locked (Status Only)

This status information indicated whether the transmitter is successfully locked to the incoming composite video signal. Unlocked status may indicate cabling faults, or poor quality incoming video feeds to the unit.

Software Version (Status Only)

This status information describes the version of the software running the SOLO transmitter product.

Sets the demodulator channel width in 25KHz steps. This must match the modulator channel width.

Demodulator Constellation (Status Only)

This field displays the COFDM constellation that is being demodulated at the receiver. In normal operation this will match that selected at the transmitter.

Input LNA gain

This allows selection of the input gain at the front end of the demodulator. Low gain mode improves the blocking on the input by about 10dB but has a similar reduction on sensitivity.

Demod Lock Status (Status Only)

This indicates whether the demodulators are successfully locked to the RF signal.

30

Input SNR (Status Only)

For each IF input, the SNR (Signal to Noise Ratio) is reported. Values in the order of 18dB to 22dB represent strong received signals, whilst values in the order of 5dB represent poor received signals which will likely give rise to decoding errors.

Input Level (Status Only)

This figure indicates the received signal level at the two receiver inputs. Normal Operation will occur when the input level is between –25 and –115 dBm. Signals greater than –25 may be too powerful and cause damage. Signal less than -115dBm may be too weak and cause data loss (typical link failure will occur around –118dBm depending on mode). The input level may also increase when the antennas are connected and there is no transmission. This indicates the presence of interference.

BER Pre-LDPC (Status Only)

This is the raw error rate prior to the error correction techniques having been applied in the receiver.

BER Post-LDPC (Status Only)

This is the error rate before the BCH decoder.

Packet Error Rate (Status Only)

This is a measure of the number of un-correctable errors in the system. Any value other than 0 with cause loss of data, break up of audio and is a good indication of link failure.

Data Status (Status Only)

This field shows the presence of data in the system by indicating the parity of the data or none if no data is present.

Data Baud Rate (Status Only)

This field reports the baud rate of the RS232 serial data component that is present and selected in the stream.

Scrambling

If the AES scrambling option has been purchased for the SOLO4 system in use, then it is possible to encrypt the link. Descrambling must also be enabled at the receiver by selecting AES128 or AES256 in the descrambling field. At this point the user will need to ensure that the correct key is in use at the receiver and this is done by selecting Options / Write AES Key in the receiver controller.

31

The key is a 128bit value for AES128 and a 256bit value for AES256, and is entered as 32 or 64 ASCII hexadecimal characters (0...F).

The AES128+ and AES256+ modes prevent clear streams from passing through the system which can be useful in certain applications.

Audio Status (Status Only)

This field shows the presence of audio in the system.

Audio Headphone Level

This allows the user to adjust the audio output level in the receiver. The nominal level is set to 0dB.

13 Control Protocols

The following section describes the control protocol employed on the RS232 link for controlling the SOLO transmitters and receiver equipment.

Connection details are detailed in previous sections.

Note that only features that are licensed for use in the SOLO units can be controlled. The protocols listed here cover all possible features. Attempting to activate an unlicensed feature will simply result in the command being ignored by the SOLO unit.

13.1 RS232 Control – General Principles

The physical interface is RS232 but this can be converted to RS 485 with an external adapter where multiple units are controlled over one RS 485 bus.

Normal operation involves sending a packet from the control device (normally a PC) to the device being controlled. If the packet satisfies an address integrity check, then the controlled device will action the command and send a reply.

For compatibility with modems an ASCII style protocol is used.

Ports are set for 8 bits, No parity, 1 stop

13.2 Packet Structure Sending (from PC)

ASCII Value STX 02h Start byte 0-9 30h-39h 4 byte unit address. In range 0-9999 R 20h-7Eh 1 byte command type. r read, w write or m misc I 20h-7E 1 byte indicator of internal data block ABC 20h-7Eh Command –three byte mnemonic ; 3Bh Separator PQR 20h-7Eh Data –Optional, variable length ; 3Bh Separator X 20h-7Eh Sum Check ETX 03h End byte

45

13.3 Packet Structure Reply (from controlled device)

ASCII Value STX 02h Start byte 0-9 30h-39h 4 byte unit address. In range 0-9999 Z 20h-7Eh Status BYTE PQR 20h-7Eh Data –Optional, variable length ; 3Bh Separator X 20h-7Eh Sum Check ETX 03h End byte

The Sum check byte is the summation of all bytes in the packet, not including the start and end bytes. Higher order bytes are ignored and the final byte result is modified to prevent ASCII control characters being sent. Bit 7 (highest) is forced high.

Status byte will indicate command performed OK, or indicate an error.

ASCII Meaning

1 All OK

E General error, Command could not be actioned

Typically E will be returned if the message is formatted incorrectly (separators in wrong place) or if commands are in upper case, or if commands do not match against the allowed list of commands, or if the checksum is wrong.

Addresses in the range 0001 to 9998 are for general use. Address 0000 is reserved and 9999 is a broadcast address. i.e. any device will reply to this address. Its reply will contain its own specific address.

All data in the transmitter and receiver is stored as one of 5 data types, Double, String, List, Integer or HexInteger. The data type dictates the contents of the data section of the reply.

• List – 1 byte for sending. Value is hexadecimal coded as ASCII. 2 byte reply. Reply represents index into original choice list. e.g. Reply 02 indicates entry 2 in original list.

• Double - variable length. Reply always contains decimal point and 4 decimal places. Can have 1 to 3 digits before decimal.

• Integer - 6byte reply. integer value with stuffed with preceding zeros. e.g. GOP reply 000012 = GOP length 12

• String - Variable length. Reply is string excluding null terminator

• HexInteger – 8byte Hex reply
