  • 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-6T75(2575) is middle distance thermal PTZ camera.

    It is widely using in most of Mid-Range Surveillance projects, such as intelligent traffic, public secuirty, safe city, forest fire prevention.

    The camera module inside is:

    Visible camera SG-ZCM4035N-O

    Thermal camera SG-TCM06N2-M2575

    We can do different integration based on our camera module.
