Hi New huy in CCTV field

Recommended Posts

Hello Friends

 

I am new in the field of CCTV Camera. I have some basic idea of insatalling camera and DVR.

 

Receintally i have insatlled 3 DOME camera along the perimeter of one of my freinds house.

it took me 2 days to insatll the camera and wirings. I have simense cable which incluse cable for the poser also.

 

All 3 camera worked fine for 1 day.But now 2 of the camera's in night show me the reflection of LED in Dome Glass ( IN day time it work fine).

And in 3rd camera dont show me anything in night seems like its infra red in not working.

 

What could be the issue ?

While doing reserch on this issue i came to know that refelection can be avoided by putting some round foam sheet on the lens so tha it touches the dome glass and hence no reflection. if this is the reason then why the camera worked fien for one night.

 

And what could be the problem for the 3rd camera in which their is no picture in night.

 

Please help ASAP
