AHD camera image deteriorating shortly after power-up

[Garyc]

hi all, this is an AHD camera, it's was off for few weeks, just after I reconnect the cable to the DVR, everything was OK until 20 mins later the image suddenly turn to condition like image 2, like there is a mesh in the middle, but outer line of the image was OK, any idea what's going on here please???

It looks like some sort of overlay has appeared in the App - does it look OK when you check it on a monitor or a PC?

Hi there, thanks for you help, I have checked the monitor and the recording footage, they are the same, I guess there is something wrong with the camera itself, the IR light won't switch on at night too
