I was trying to assist our local PD with a grand theft in our building. Unfortunately wasn't very successfull. Our cameras caught all the events, however, the resolution is not that great. They couldn't recognize the face of the suspect. The video was to grainy and useless for them.
What would you guys recommend? Replacing the whole DVR system, or is there a way to put a better camera's compatible to same model of DVR. Recently replaced few cameras with better Sony make but not much better.
Anyone has experience with that?
