Details
The camera is part of the Cooper series, which offers simple and highly cost-effective solutions.
HAC-T2A21-0280B is a camera capable of recording video at a resolution of up to 2 megapixels. Despite its low price, the camera delivers excellent performance in both day (high quality, 1080p resolution) and night (0.04 lx sensitivity) modes. The camera’s plastic housing has an IP67 rating, ensuring protection against dust and rain. The built-in infrared illuminator with a range of up to 20 m and a smart IR function reduces image overexposure and ensures operation regardless of lighting conditions.
The HD-CVI video transmission and encoding system allows high-definition video to be transmitted via coaxial cable or twisted-pair cable (when special video transformers are used). The transmitted image takes the form of an analogue signal, with a significantly wider transmission bandwidth than CVBS. The signal is not compressed, which makes the image more accurate and clearer during live viewing. Its advantages include the absence of delays and easier system configuration compared to IP cameras.
Multi-system camera
The camera supports four analogue systems: HD-CVI, AHD, HD-TVI or CVBS. Thanks to its compatibility with commercially available systems, this is a versatile camera whose signal can be adapted to the requirements of the installation. A particularly important advantage is the ability to work with older-style recorders (in the CVBS system). Operating modes can be switched using the UTC PFM820 Q498200A controller or via the camera menu displayed on the recorder.
Multilingual OSD menu
Camera parameters are controlled via the recorder or the UTC PFM820 Q498200A controller. Data for the camera’s OSD is transmitted via a coaxial cable together with the video signal. This solution allows the most important camera parameters to be changed, including remotely, in a convenient and efficient manner. The interface is available in, amongst others, Polish, English, French, German and Spanish.
Smart IR
The infrared lighting has been designed to deliver maximum performance. The intensity of the emitted light is dynamically adjusted. The illumination is adapted to the distance from the observed object, ensuring that it remains clearly visible and is not overexposed when moving closer to the camera.
