My China Star

Digital HD video surveillance of the VHS videotape that today technology of video surveillance in the professional field has not much with the classic video technology in the form of tape recorders in the VHS format common. The tape recorder is certainly unchanged in each video systems and carries out its work unchanged, but is uncomfortable, maintenance-intensive, and equipped with an outdated resolution compared to current video-surveillance systems. Modern video surveillance systems record the monitoring images on disk until the disk is full and then overwrite the oldest”video data on the hard disk. Alternatively, an expiry date allows for privacy reasons quasi”program for the video data determines how long the maximum data. Record the modern video surveillance systems on disks that are designed for 24/7 operation, the recorders are basically maintenance-free. Allow the recording of the video systems per schedule programming. The recording is in progress do not have everyday and also not around the clock, but only if it is necessary, z.. in the operation-free time or grade in the operating time. In addition can be the recording via automated motion detection in the image or by external sensors start taking several hours, a closed door without public interest only hard drive capacities to save or video data to emerge, if something is actually happening because rarely! The resolution of the video recordings has evolved significantly. Modern HD cameras and megapixel cameras high resolution images, which provide details himself very well recognize leave and are still clearly actionable by a zoom function. Surveillance cameras with 1.3 megapixels, 2 megapixels, 3 megapixels, but also with resolutions about it and the associated recording systems available on the market for security systems and video surveillance technology. But also the copy of the video data to pass to the police has simplified sichdeutlich.
