  • Target: Human size is 1.8m×0.5m (Critical size is 0.75m), Vehicle size is 1.4m×4.0m (Critical size is 2.3m).

    The target detection, recognition and identification distances are calculated according to Johnson’s Criteria.

    The recommended distances of Detection, Recognition and Identification are as follows:












    3194m (10479ft) 1042m (3419ft) 799m (2621ft) 260m (853ft) 399m (1309ft) 130m (427ft)

    SG-PTZ4035N-3T75(2575) is Mid-Range detection Hybrid PTZ camera.

    The thermal module is using 12um VOx 384×288 core, with 75mm & 25~75mm motor Lens,. If you need change to 640*512 or higher resolution thermal camera, it is also avaiable, we change change camera module inside.

    The visible camera is  6~210mm 35x optical zoom focal length. If need use 2MP 35x or 2MP 30x zoom, we can change camera module inside too.

    The pan-tilt is using high speed motor type (pan max. 100°/s, tilt max. 60°/s), with ±0.02° preset accuracy.

    SG-PTZ4035N-3T75(2575) is widely using in most of Mid-Range Surveillance projects, such as intelligent traffic, public secuirty, safe city, forest fire prevention.

    We can do different kinds of PTZ camera, based on this enclosure, pls check the camera line as below:
