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

Wide-area outdoor perimeter and open-site monitoring that needs one panorama view plus a 25x zoom detail channel.

Before you orderConfirm your recorder supports this dual-channel PTZ and that the mounting point covers the intended overview and zoom sightlines before ordering.
01
Dual-Channel Coverage

A 4MP overview channel and a separate 2MP detail channel let one camera watch the wide scene and zoom in at the same time.

02
25x Optical Zoom

The detail lens reaches from 5 mm to 125 mm, so operators can pull in distant subjects without losing the panorama view.

03
Smart Dual Light

IR and white-light illuminators support night viewing, with up to 100 m IR reach on the detail channel.
