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 perimeter and entrance coverage where a vari-focal 2MP HDCVI bullet camera with 40 m IR is needed.

Before you orderConfirm your recorder supports switchable HDCVI/AHD/TVI/CVBS at 1080p and that a 12 VDC power supply is available at the mounting point.
01
Flexible Vari-Focal View

The 2.7-12 mm manual vari-focal lens lets you adjust the field of view on site to frame gates, driveways or walkways precisely.

02
Long-Range Night Vision

Smart IR reaches up to 40 m, helping keep the scene visible after dark while reducing overexposure on nearby subjects.

03
Multi-Format Output

CVI, CVBS, AHD and TVI are switchable, so the camera can match a compatible recorder without swapping the unit.
