VSP SERIES INT 191507 - DITEK Surge Protection
... 1. Connect the incoming feed from the “Field” to the INPUT side of the DTK-VSP. 2. Connect an appropriately tipped 3’ patch cable from the DTK-VSP to the equipment to be protected to allow for reaction time of the SPD. 3. Always have one common ground per system to eliminate the possibility of a dif ...

the Humbloc – Groundloop Isolator
... The Humbloc should be fitted between the camera and the input of CCTV equipment such as a DVR that it is connected to; generally speaking the Humbloc would be fitted at the rear of the DVR to its “video input(s)”. For example in a 4 camera system it is possible that only one camera has an earth loop ...
