What this camera does
This PTZ security camera is made for locations where you want to leave nothing to chance. The panoramic overview works seamlessly with the PTZ lens, which automatically tracks targets. Smart Dual Light technology switches intelligently between discreet infrared and bright white light on detection, while the red and blue warning light and sound actively deter intruders. Thanks to IP66 protection and lightning protection (TVS 6000V), this camera is ready for any type of weather.
