Wired connection console and TV
Usually, the console is connected to the TV through a cable, which can be easily switched.
Hard disk video recorder scheme
Choose a hard disk video recorder with circular output function and matrix function, which can be displayed directly on the wall by simple connection.
Matrix connection scheme
Wall display can also be achieved by connecting the matrix to the distributor and frequency divider.
AV input port switching
Please avoid installing the device on the set-top box when installing. It is best to connect directly to the AV input of the TV. Generally, TV has 2-3 AV input ports. You can plug the set-top box into one port, plug the surveillance camera into another port, and then switch by selecting AV 1 or AV2 without interference.
