Can anyone help point me in the right direction? I have just bought one of these http://domarsolutions.co.uk/babybullet-zxtech-2-megapixel-ip66-broad-lens-bullet-cctv-camera.html and following the instructions by my router provider changed the http port from 80 to 8081 and now I cant access my camera. I have tried camera default 192.168.1.168 which was working before I changed the settings and I have tried 192.168.1.168:8081. Now I cant access my camera to change the setting back, how do I find a way in?
