Surveillance Cameras

CCTV cameras are literally the eyes of any CCTV system. And although the technology for transmitting a video image from a surveillance camera and the way it is recorded, stored and processed on a server also play an important role, the capabilities of video surveillance systems primarily depend on video surveillance cameras. Surveillance cameras can be classified according to several principles - technology for receiving and transmitting a signal, functionality, scope, climatic performance and many others. Currently, in the market of security systems, you can find CCTV cameras to solve almost any task related to surveillance.

Analog and IP Cameras

Initially, all CCTV cameras were analog - they generated a video signal that was transmitted over analog communication lines, and then output to a TV or monitor, and also recorded in analog form or digitized. The advent of digital IP cameras has greatly simplified the transmission and storage of information from surveillance cameras, made it possible to increase the image resolution and the distance over which video is transmitted, and also significantly expanded the functions of the surveillance cameras themselves.

Outdoor, Indoor and Hidden Security Cameras

Depending on the purpose, CCTV cameras are available in various designs. For outdoor video surveillance systems, cameras are used, the housing of which is designed for operation in a wide range of temperature and humidity, and is also resistant to precipitation. For video surveillance systems in an office or other premises, cameras are used that allow you to provide optimal visibility within rooms of various configurations and sizes. If the video surveillance system should be invisible, miniature surveillance cameras are used, which, during installation, are masked by interior or decoration items.

Functionality of CCTV Cameras

Surveillance cameras can perform a very different range of functions depending on their design and equipment. At its simplest, a surveillance camera is just a video source. The expansion of the functions of CCTV cameras can go in several directions. For example, night vision or infrared illumination is often used, the camera can be permanently fixed or controlled, with or without optical zoom. The advent of IP cameras further expanded their functionality - digital cameras can track movement in specified segments and perform a certain set of actions, often such cameras can be operated autonomously - all work with them can be done through the interface of the camera itself.

How to Choose a CCTV Camera?

Choosing a CCTV camera is not as easy as it might seem at first glance. Surveillance cameras are so diverse in design and purpose that only a specialist can make a competent choice, having studied all the features of the territory of the facility where surveillance cameras will be installed. The best option is to entrust the choice of a video surveillance camera to specialists with experience in the field of security systems.
