How to connect surveillance cameras:
Connect the cameras via a switch device and assemble the cameras and display them on the TV, so this device will not enable you to record, but immediate and direct monitoring, and if you have only one diameter surveillance camera, you will not need the switcher, you can connect it directly to the TV
* There are multiple capacities of recording devices and switches according to the number of cameras 4 entrances and 8 for moving cameras can be controlled by recording devices that support PTZ cameras or can be connected to a zoom dimension you can control the moving cameras and zoom and rotate the camera and you can also not allow the installation of internal cameras in workshops, hotel rooms and furnished apartments, as happened in one of the furnished apartments and a women's wedding hall I caused them a big problem because they were putting hidden surveillance cameras, and they could be limited here to small thumb-sized cameras and cameras in the form of an air freshener glued to the wall and cameras in the form of a smoke and heat detector for a fire alarm and be installed on the ceiling
So please check such places before sitting in them
And for those who wanted to monitor the external doors of the House, install gate cameras, and there is no need to install surveillance cameras, which may be expensive .
