CCTV Video and IP Video System Media Converter |
Posted: April 29, 2021 |
In today's world, video protection and surveillance networks are needed in all aspects of life. With a security device in place, it's easier to keep an eye on the premises and collect information in the event of an incident. However, the growing popularity of surveillance cameras has resulted in new video quality, bandwidth, and distance capabilities that are beyond the current copper cabling system's capabilities. We'll look at a new cabling approach for CCTV analog video systems and IP video systems that uses fiber optic cabling and fiber media converters.
Introduction to the Video Security and Surveillance Network The increasingly popular video security and surveillance can be achieved using a variety of devices, the most important of which are CCTV analog video and IP cameras.
Analog Video System (CCTV) Fixed analog CCTV cameras are connected to a central management system (VCR—video cassette recorder or DVR—digital video recorder) through coaxial cables in a traditional analog video network. An additional controller has been added if the camera has a PTZ (Pan-Tilt-Zoom) capability. IP-based video surveillance Network (IP) cameras are linked directly to the local area network through UTP cabling and switches in this standard IP video surveillance network. Rather than sending a feed to a Digital Video Recorder, they will transmit and receive data over a computer network (DVR). Any PC or server on the network can record video. The most distinguishing feature of an IP video surveillance network is that each camera has its IP address to distinguish itself from the others in the network. The cameras can be accessed from anywhere in the world since they are IP addressable. The Necessity of Fiber Media Converter in CCTV Analog Video and IP Video System Both types of cameras work well in either commercial or residential security. IP cameras use UTP cabling (at least Cat5), and analog cameras can use either coax or UTP (at least Cat3). These media have poorer performance than the fiber optic cabling in both the transmission distance and the bandwidth. However, it is not easy to replace the current cords with fiber optic cables. The project may encounter the following challenges:
The Ethernet cables fixed in the wall, under the ground need to be changed by the experts The legacy devices are not equipped with fiber optic ports
As a result, a more appealing fiber optic cabling approach for CCTV video systems and IP video systems with fiber media converter has caught the attention of professionals. The electrical video signal can be converted to an optical format by the fiber media converter. The following edges are also present: Converting UTP to fiber without having to switch or replace the existing copper cabling saves time and effort. Assisting in the transition between legacy copper networks and fiber-related equipment
How to Use a CCTV Media Converter Video System (Analog and IP) Media converters are available in a number of configurations, including normal, controlled, and industrial models, as well as PoE media converters that can convert optical signals to electrical signals while also providing power to PoE devices over a single Ethernet cable. The fibre media converter and the PoE media converter are used in the examples below.
CCTV Analog Camera System with Fiber Media Converter A traditional analog video structure with fiber optic cables and media converters is shown in the diagram below. A pair of fiber media converters should be installed between the server room and the cameras to link the fixed analog cameras to the VCR or DVR. Fiber optic signals can be used to relay video signals. Two types of signals, one for video and one for data, should be converted into fiber optic signals for analog PTZ cameras. As a result, either two separate media converters or a fiber media converter with both functions should be mounted. Fiber media converters are considered to work best in pairs.
