Samsung Techwin’s new SIR-4250 dome camera, with built-in IR LEDs, can generate quality images even when the area that is monitored is in total darkness, the makers report.
The SIR-4250, which is equipped with a varifocal lens, is described by the manufacturers as a true Day/Night colour/monochrome camera. Its infra-red cut filter automatically switches the camera’s functionality to deal with changing lighting conditions. During the day the SIR-4250 delivers colour images at 520 TV lines while at night this product can capture monochrome images at 570 TV lines.
With a WIII chipset, the SIR-4250 can boast a number of technical functions, including a four zone privacy image masking function and motion detection whilst the on-screen menu camera settings can be changed remotely via RS-485 communication. A white balance feature ensures picture quality when used with supplementary sodium lighting, the makers add.
The built-in high performance LEDs are up to four times brighter than ordinary LEDs ensuring camera visibility of up to 16 metres in ultra low light conditions, it is claimed.
The SIR-4250 can be mounted on a wall, ceiling or a slope and its three-axix rotating dome mechanism ensures that the camera can be positioned exactly as required. SSNR (Samsung Super Noise Reduction) technology incorporated into the SIR-4250, dramatically reduces the noise from captured video. The result of this is a much reduced recorded file size, it is claimed, up to 70 per cent, when using MPEG-4 compression and 40 per cent when using JPEG and thereby reducing the size of hard disc required. With MPEG-4 this is the equivalent of recording up to three times more on a hard disc compared to a camera that is not equipped with SSNR.
