High-speed PTZ cameras—DALLMEIERNO Deposit bonus $43

With the DDZ4220HD and DDZ4230HD Dallmeier launches new PTZ cameras with a resolution of as much as two megapixels. 

The cameras of the series DDZ42xxHD are high-speed HD PTZ dome network cameras. They're equipped with a high-performance Pan-Tilt-Zoom mechanism and supply real-time high-definition video with as much as 30fps at a resolution of 2MP. Probably the most advanced sensor and encoder technology and the subtle image processing provide recordings with excellent contrast, brilliant clarity in addition to highest detail resolution and colour fidelity.

The DDZ4220HD features 20x optical zoom and the DDZ4230HD 30x optical zoom with auto-focus. The high zoom factor makes it possible for the straightforward and discreet surveillance even of faraway objects. Functions like “Digital WDR (Wide Dynamic Range)“ and “3D DNR (3D digital noise reduction)“ guarantee good image quality. The superb light sensitivity of the sensor and the subtle image processing ensure crisp colour images even in low lighting. In night mode, the cameras also provide outstanding results because of the excellent infrared sensitivity. The PTZ cameras are equipped with a removable IR cut filter, and will automatically switch between day and night mode. In addition, different day and night presets for the exposure settings will also be defined and adjusted.

Up to 128 preset positions and 32 tours can also be programmed. Particularly useful in that regard are the adjustable alarm actions with contact closure: If a undeniable contact is closed i.e. triggered, as an example by opening an entrance door, the camera automatically moves to the programmed preset position of the relevant scene.

The DDZ4220HD and DDZ4230HD are equipped with a RAM memory that may be utilized 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 quick transmission to the SMAVIA recording system. This stores the video stream with high speed after which continues the recording of the live stream seamlessly.

The PTZ dome cameras are available an in-ceiling, surface or weatherproof housing. The in-ceiling variant of the camera is tested in keeping with the stringent requirements of the UL 2043 when it comes to flame retardancy and coffee smoke emission. Thus, it's approved for installation in air-conducting space, as an example in air shafts or false ceilings dissipating the air to a central air conditioning.

The PTZ cameras can also be conventionally provided with 24 V AC or conveniently with Power over Ethernet (PoE+).
