Security Recording Kit

The same security system, model 575 as Advertised didn't have the built in audio microphone. The unit does good in daylight conditions. Night time conditions with no light I cannot make out any very little movement if any at all. Low light conditions at night doesn't do very well either. can make out some movement at 7 to 10ft. Not very good night time security. A good system for daytime security. I would recommend this unit if you wanted a good daytime security system not very good for night. I think that must to have a system to monitor well at night!
