DESCRIPTION


The cameras of the series DDZ4220HD are high-speed PTZ dome network cameras with 20× optical zoom. They are equipped with a high-performance Pan-Tilt-Zoom mechanism and provide real-time high-definition video with up to 30fps at a resolution of up to 2MP. The most advanced sensor and encoder technology and the sophisticated image processing provide recordings with excellent contrast, brilliant clarity as well as highest detail resolution and color fidelity.

Very good Low-Light characteristics
The very good light sensitivity of the sensor and the sophisticated image processing ensure crisp color images even in low lighting. In night mode, the camera also provides outstanding results due to the good infrared sensitivity.

Automatic switching of presets
The camera is equipped with a removable IR cut filter and can automatically switch between day and night mode. In addition, different day and night presets for the exposure settings can be defined and adjusted.

EdgeStorage
The camera is equipped with a RAM memory that is used by the EdgeStorage function for storing the video stream in case of a network failure. When the network is restored, the SmartBackfill function ensures a fast transmission to the SMAVIA recording system. This stores the video stream with high speed and then continues the recording of the live stream seamlessly.

Plenum Rated
The in-ceiling variant of the camera is tested according to the stringent requirements of the UL 2043 relating to flame retardancy and low smoke emission. Thus, it is approved for installation in air-conducting spaces and can be mounted for example in false ceilings dissipating the air to a central air conditioning.
