Hard disk recorder for 4 cameras with and without PoE
Which hard disk recorder (NVR) should I choose?
You must select an NVR with PoE : If the cables from all your surveillance cameras all end up at the recorder. The hard disk recorder has built-in ports for each camera and provides power to the cameras through the network cable. You therefore also save a 230v plug, as you will not need a separate PoE switch. Economically, there is not much difference, so you need to choose the one that best suits your installation
You should choose an NVR without PoE: If it is easier to run the cables to the nearest switch or the cameras are on another network. The smart thing about a recorder without PoE is a very flexible system, e.g. if you need to have 4 cameras located in an extension or the other end of the house, then you only need to pull the cables to the nearest switch and then a single cable from that switch to the next.
