Dahua Technology A21BB03 2MP Outdoor Analog HD Bullet Security Camera with 3.6mm Lens & Night Vision



2MP IR 3.6mm HDCVI Mini Bullet

Experience the superior clarity of Full HD 1080p video while leveraging your existing coaxial infrastructure. The camera provides multiple video formats for easy integration when using competing technologies.

The camera’s Smart IR technology adjusts the intensity of the camera’s infrared LEDs to compensate for the distance of an object, preventing the IR LEDs from whitening out images as they come closer to the camera. This series is suitable for indoor or outdoor applications.

The outstanding performance and low price make the camera an ideal choice for small businesses that value surveillance.
