Two kinds of CCTV cameras are available that provide powerful protection against criminal activity possibly damaging your home or business – analog and digital CCTV.
Analog closed circuit television systems use either a wired configuration or a wired transmitter to transmit images to an associated receiver. Wired systems run a wire between the monitor and the camera and sent data via a coaxial cable. Signals transmitted through these cables and wires are inputted to one or several monitors to be viewed and/or recorded. A device called a “multiplexer” is required if the user wants to see multiple camera display feeds on one monitor rather than several screens. Audio transmissions are generally relayed utilizing copper wiring instead of coaxial cables.
Digital CCTVs are used much more extensively than analog CCTVs because they allow users to access the internet in order to view their home or business while away. Internet Protocol cameras (IP cameras) are equipped with hardware that permits conversion of video and audio signals over to packet streams that are then transmitted through a LAN (local area network), WAN (wide area network) or the internet.
Advantages of digital CCTV security systems over analog systems are numerous and include:
High-quality and dependable CCTV systems sold by professional security companies like Vertex Security have the ability to capture at least 30 frames per second, which is considered “real-time”. Although two to six or seven frames per second is adequate enough to record a criminal, home or business owners using digital CCTVs entertain a much higher possibility than users of analog devices of helping the police find and arrest the suspect due to providing such high resolution images.
