ZKTeco BS-31A11A 720p HD Analogue Bullet Camera

The BS-31A11A is an entry-level 720p analogue bullet camera from ZKTeco's EZ series, for basic coverage on coaxial CCTV systems in homes, shops, and small compounds.

It records 1280 × 720 at 25/30 fps from a 1/4-inch sensor through a 2.8 mm lens with a 63° view. Ten IR LEDs light the scene 10–20 m at night, and output switches between AHD, TVI, and CVI to suit the DVR. Video can travel 500–800 m over coaxial cable.

The housing is rated IP66 for outdoor use and runs from -30 °C to 60 °C on a 12 V DC supply, drawing under 3.2 W, with a ±30% input voltage tolerance.

At 720p it is suited to general monitoring and to extending an existing 720p system; for identifying faces at gates or doors, we recommend a 1080p or higher camera such as the BS-32B11M. ZKTeco has discontinued this model; if stock runs out we will quote the nearest current equivalent.
