Evertech Cctv Infrared Security Camera - 30 Ir Led(82ft Night Vision) Cctv Camera, 1/3 Inch Sony Su

3.6mm (slightly 'fisheye') lens an improvement in field of view over original 6mm. I would never buy 6mm lens (they come with orig. systems). Day and night vision a little better in clarity and color than original 400tvl cmos. IRs light up well at least 40 to 50 feet. 2x big as original 400tvl cmos with sturdier mount. If this is using Sony Super HAD chip it's not doing it near as well as full Sony, but then it was only $56. Good enough to keep until I get a full Sony and move this one to the back.

Was on time with UPS.

VERY IMPORTANT NOTE!!!

Getting a better camera(s) is useless if you cannot record at the 30 fps(images per second) AT THE FULL D1 SETTING on the DVR or NVR. 1 fps at D1 uses up a lot more than 1 fps C1 (HD1 is 'half D1' quality, it's not linear comparison). The image resolution is degraded at less than that, but it is crucial to good facial recognition. This is a big problem with most DVRs that have more than 4 cameras input (some will not do 30 fps D1 on all 4 even then !). If it claims at least 120 fps D1 total for a 4 channel DVR/NVR then you can be fairly sure it can allow up to 30 fps per camera D1.

Do the research on the DVR FIRST!!
