Camera/DVR Compatibility Question

Recommended Posts

I want to upgrade the old, lousy cameras I have on my DVR-based surveillance system.

 

Somewhere I read something about some surveillance DVRs being unable to use cameras with resolution above a certain unspecified TVL limit. There was no further elucidation.

 

What, if anything is this about? I don't want to buy the wrong cameras.

 

Many thanks for any clarification!

Hi. It depends on your dvr ..... If you are only analog then you are not going to see much benifit just replacing with analog cameras
