Video surveillance systems are an integral part of any comprehensive security system. A video surveillance system plays a vital role in a comprehensive security system, not only detecting unauthorized entry into a protected facility but also identifying the intruder. Video surveillance systems not only monitor the protected area but also record images and, often, alert users to any emergency situations. Video surveillance systems are typically used in conjunction with alarm systems, which make video surveillance more effective.
Video Surveillance Systems
Various types of video surveillance systems are currently in use – analog, digital, and hybrid. Each type of video surveillance system has its own advantages and disadvantages, so careful consideration should be given to the selection of a video surveillance system for each specific application.
Analog video surveillance systems are currently obsolete, but in some cases their use is justified due to their relatively low cost. Analog image recording systems are currently virtually nonexistent, so an analog video surveillance system makes sense for simple surveillance of a facility's territory, without the need to record or analyze the resulting images.
Digital video surveillance systems are modern systems for acquiring, recording, storing, and analyzing images, built using IP technology. Digital video surveillance is a progressive technology that ensures high image quality, reliability, and operational efficiency. Digital video surveillance systems allow the use of various communication channels for data transmission, including GSM mobile communications, Wi-Fi wireless technology, or the internet.
Video surveillance systems are typically used in conjunction with alarm systems and perimeter security systems, allowing for more effective use of video surveillance. For example, Egoza barbed wire installed around the perimeter of a facility, a digital video surveillance system, and alarm provide a much higher level of security than either system alone.
