Why this model

Product Features

What this model is for, what it does well, and what to confirm before it goes on a project.

Best for

Outdoor entryways, driveways and small commercial perimeters that need a simple 2MP bullet camera on an existing coax DVR.

Before you orderConfirm your recorder supports HDCVI or the switchable format you plan to use, and check the 2.8 mm, 3.6 mm or 6 mm lens option plus stock lead time before ordering.
01
Four-Signal Flexibility

Switch between CVI, CVBS, AHD and TVI output so the camera can match the recorder already installed on site.

02
Smart IR at Night

Two IR lights with Smart IR reach up to 20 m, helping keep faces and plates visible in low light without harsh overexposure.

03
Weather-Ready Housing

An IP67-rated body and 12 VDC power make it a practical choice for exposed outdoor mounting points.
