Dallmeier DDZ4220HD and DDZ4230HD: PTZ video surveillance with 2MP resolution

These cameras incorporate the DIGITAL WDR and 3D-DNR functions, to ensure image quality, while the sensor's light sensitivity and sophisticated image processing allow, even under low-light conditions, very detailed color images.

Dallmeier has expanded its line of video surveillance solutions with the addition to its PTZ range of the DDZ4220HD and DDZ4230HD models. These equipments are equipped with a high-performance Pan/Tilt/Zoom mechanism and provide real-time HD video of 30ips with a resolution of up to 2MP. Its sensor and encoder technology and image processing deliver images with optimal contrast, bright sharpness as well as maximum resolution in detail and fidelity in color.

The DDZ4220HD has a 20x zoom and the 30x DDZ4230HD with autofocus. High zoom factor allows for easy and discreet protection of even farther objects. Features like Digital WDR (wide dynamic range) and 3D-DNR (3D digital noise reduction) ensure image quality.

Sensor light sensitivity and sophisticated image processing enable, even under low-light conditions, rich color images in detail. In night mode, the cameras also offer good results thanks to their infrared sensitivity. They are equipped with a removable IR cutting filter and can automatically switch between day and night modes. In addition, it is possible to define and adapt in the exposure settings different presets for day and night.

Until 128 preset positions and 32 tours can be scheduled. They also have adjustable alarm actions in case of contact. If a particular contact is activated, for example by opening a front door, the camera automatically moves to the defined preset position of the scene to be monitored.

The DDZ4220HD and DDZ4230HD are equipped with RAM that the EdgeStorage function uses for video stream storage in the event of a network crash. When the network is restored, The SmartBackfill function is responsible for transmitting the recorded images to the Smavia recording system. It memorizes the video stream at full speed and continues recording the live stream without loss or breakdown.

PTZ dome cameras are available in a surface housing, recessing or weather protection. The recessed variant of the camera meets UL requirements 2043 in terms of fire resistance and low smoke generation, so they can be installed in air circulation spaces and mounted on false ceilings that evacuate ambient air to a central air conditioning system.

PTZ cameras can be conventionally powered by 24V AC or Power over Ethernet (PoE+).
