Analogue CCTV is great mainly because its so simple to use. It is very much a ‘plug and play’ system – Any camera can be used with any screen (with the same type of inputs). Analogue CCTV also has next to no latency from input to the display, so is well suited for applications like MD/Show relays. The only downside to analogue CCTV is that it can require more infrastructure over IP based CCTV. A separate cable is needed for both the power and video, and only 1 video stream can run over a single BNC cable.
IP based CCTV is great for distributing large amounts of video easily and dependably. A single Cat5e cable can carry both power and video for the camera up to 100m. These cameras can be distributed over large networks and even externally to the internet. Multiple video streams can also run over a single cat5e cable. Due to the IP Based nature, sadly there is some latency involved with this setup, using the Reolink cameras and their PC based client, you will expect about 1 second latency on a full HD Stream. Theses cameras are well suited for monitoring large spaces such as immersive theatre, however would not be a great fit for MD/Show relays.
Video Over IP
The Show Works VoIP-01 system allows the sending & receiving of HDMI signals over a standard IP network, introducing almost unlimited possibilities for the distribution of video. Both the 01-TX (transmitting) and 01-RX (receiving) units are powered via POE. Simply connect both units to a POE switch and away you go. The Show Works VoIP units operate using a broadcast protocol to distribute the video signal across the network, meaning 1 transmitter can be used with multiple receivers. For multiple transmitters and receivers on the same network, simply separate the associated devices using VLANs.
The TESmart HDMI KVM Extender allows you to work just like you would at a computer from almost anywhere by sending the HDMI and USB signal over a standard IP network. No longer does the screen and keyboard need to be next to the physical computer. Up to 16 separate transmitters and 253 receivers can be used at a time on the same network. By using the dip switches on each unit you are able to toggle between 16 separate channels of video/usb control.
