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

Long-range perimeter and open-area surveillance where a single PTZ must zoom in on distant activity day or night.

Before you orderConfirm your recorder supports this PTZ's network protocol and that the 50 m IR range and mounting position cover your target area before ordering.
01
25x Optical Zoom

Reach distant subjects across large sites with a 5-125 mm lens that closes in without losing image detail.

02
Starlight Low-Light Imaging

A 1/2.8" STARVIS sensor keeps color detail down to 0.005 lux so night scenes stay usable.

03
Invisible IR Coverage

Six invisible IR illuminators light up to 50 m without visible glow, supporting discreet monitoring.
