VH211-A4 Series HD 4MP WDR IR Smart IP Bullet Camera adopts a 1/3″ progressive scan CMOS sensor and has an internal 2.7-13.5mm & 7-22mm HD motorized zoom lens, together with internal dot matrix LED IR illuminators covering 50m distance. The output power of IR illuminators can be automatically adjusted according to the lighting of the scene to avoid full load, greatly reducing the power consumption and extending the service life.

The camera adopts H.265/H.264/M-JPEG encoding, features high resolution up to 2592×1520@20fps and provides outstanding color rendition which helps you get richer and more accurate details.

The camera also features multiple smart functions, including detection of wire-cross, intrusion, scene change, defocus and color cast, as well as low brightness and high brightness, which makes it suitable for all kinds of high-end applications.

The camera is compact in structure and easy to install.
The products can be widely used in sites that demand high-definition image quality with no lighting of ordinary buildings, supermarkets, hotels, shops, parks, schools, factories, warehouses, underground parking lots, etc.
