Many of obsolescent video surveillance systems in Kiev and the region should be replaced. Old systems do not meet modern requirements to video quality from video surveillance cameras. Digital IP-system installation requires new cable lines which is not always possible but also costly enough. Old transmission lines have been mainly laid out with co-axial cables (РК-75, RG6, RG-59) with wave impedance 75 ohm. Replacement of analog equipment by AHD (Analog High Definition) is the way out.
Modern technologies of video signal transmission and of its processing evolved dramatically. In 2014 AHD cameras and recording devices emerged on the market of video systems. Besides, for the current moment AHD equipment price is commensurable with price for analog equipment, the quality is comparable with IP. The advantage is indisputable. High, up to 500 m video signal transmission range without extra requirements to co-axial cable quality. Interference protection ratio is higher than of analog equipment. Image quality is high under resolution 1280х720 (720р), 1280х960 (960р), 1920х1080 (1080р). Complete absence of video signal delays usually typical of IP-systems.
AHD video recording devices can work in three operating conditions: IP, analog and AHD (that means that IP, AHD and analog cameras could be connected to video recording devices). As easy installation, adjustment and maintenance as of the analog systems should be also noted. But to be honest, AHD systems are more expensive than the analog ones; IP systems can record the image of better quality with resolutions exceeding 1080p. Nontheless AHD video surveillance systems are a golden mean within a variety of video surveillance security systems.
Caiman Production Group is ready to install AHD video surveillance system of DigiGuard™ with customers’ software support Dahua (PSS/iDMSS/gDMSS) in Kiev and in Kievskaya region. PG Caiman Co., Ltd. is ready to set up complex system of perimeter protection on small objects with perimeters up to 1000 m, composed of engineering obstacles like Egoza barbed wire and of AHD video surveillance systems.
