Part1:ConfiguretheRouter

a) Plugtherouterin.b) Connecttothatwirelessnetwork,ordirectlytotherouterviaethernet.c) Goto:http://tplinklogin.net/.(IfyoudonotseetheTPLINKdashboardandinsteadseesome

randomwebpage,pleasemakesureyouareconnectedtoyourrouterandnotsomeotherwirelessnetwork)

d) TheveryfirsttimeyouconfiguretherouteryoushouldrunthroughQuickSetupunderBasicSettings.ThiswillrequireyoutoconnecttheroutertotheinternetusingtheblueWANportontheback.

i. AutoDetectLettheRouterautomaticallydetecttheconnectiontypeyourISPprovides.

ii. EnableSecurity,andsetapassword.

e) TakenoteofyourpasswordandSSIDfortherouter.Thecameraneedsthisinformationinordertobeabletoconnecttotherouter.

Part2:ConfigureyourCamera

a) Connectthecameratotherouterviaanethernetcableandpoweriton.b) DeterminethecamerasMACaddressandcurrentIPaddress:

c) EnterthatIPaddressinyourbrowser.Youwillneedtologinwiththedefaultcamerausernameandpassword.Iftheseappeartobesettosomethingotherthatfactorydefault,thenfindtheresetbuttononthecameraanduseapapercliptoholditdownfor30secondswhilethecameraispoweredon.

i. LinksysCamera:EnterIPaddress(ex:http://192.168.0.101)thenclickadvanced

ii. EasyNCamera:EnterIPaddresswithport81(ex:http://192.168.0.102:81).SignintoServerPushMode.

d) Verifythatyoucancaptureanimagefromthecamera

i. LinksysCamera:http://[INSERTIP_ADDRESS]/img/snapshot.cgi?

ex:http://192.168.0.102/img/snapshot.cgi?

ii. EasyNCamera:http://[INSERTIP_ADDRESS]/snapshot.cgi? ex:http://192.168.0.101:81/snapshot.cgi?

Note:theEasyNcamerausesport81,whiletheLinksyscamerausesdefaultport80.

e) GivethecameratheSSIDandpasswordforyourwirelessrouter.JustlikeyouneedtheSSIDandpasswordtousetherouterwirelessly,yourcameraneedsitaswell.

f) Turnoffthecamera,unplugtheethernetandturnthecamerabackon.

g) Verifythatthecameraisabletoconnecttotheinternetwirelesslybygoingtohttp://tplinklogin.net/andlookingunderDHCPclientscheckingthatyourcameraislisted.

h) Verifyyoucancaptureanimagewirelessly

Part4:CapturingandEditingImagesusingMATLAB

1) Readinganimagefromthecamera:

Youshouldbeabletocaptureanimagefromthecamerausingthesameurlsthatwereenteredintothebrowser:

%linksyscamera:%example:image=%imread('http://192.168.0.102/img/snapshot.cgi?)image=imread('http://[IP_ADDRESS]/img/snapshot.cgi?)%easyncamera:%example:image=%imread('http://192.168.0.101:81/snapshot.cgi?)image=imread('http://[IP_ADDRESS]/snapshot.cgi?)

Wehavehadissueswheretheaboveurlsworkedinthebrowser,butnotthroughMATLAB,ifthisisthecase,thenpassthecamerasusernameandpasswordaspartoftheurlinordertocaptureanimage:

image=imread('http://[IP_ADDRESS]/snapshot.cgi?user=admin&pwd=&resolution=16&rate=0')

2) DisplayacapturedImage:

imshow(image)

3) Indexlayersonanimage

red_layer=image(:,:,1)green_layer=image(:,:,2)blue_layer=image(:,:,3)

4) Findtheresolutionoftheimage

resolution=size(image)resolution=resolution(1:2)

5) ConvertanRGBimagetoGrayscale

gray_image=rgb2gray(image)

6) Drawonanimage

draw_image=imagedraw_image([50:100],[50:100],:)=0
