CCTV HD 1080P 2MP Mini Spy Pinhole Security Camera 2000TVL 3.6mm 90degree Mini AHD Hidden Surveillance Camera, For 1080P 4-in-1 TVI/AHD/CVI/CVBS/960H DVR System

Nice little CCTV camera impressed with picture quality on both day and night modes.Can't say about in built microphone as I'm not using that function.

This 2mp camera is excellent to use in all conditions. It may get warm but I've left it on overnight and it works very well no problems at all.
