Yes, we strongly advise you to add an inverter to your videosurveillance system to avoid electrical failures such as voltage drops, surtensions, cuts or micro-cuts, peaks, distortions...
You can contact your usual electrical distributor to choose your inverter and define your power needs.
How to calculate power requirement :
1- Measure the consumption in Amperes, Watt or VA (Apparent Power) of your device
2- Choose an inverter with a higher power of about 20%.
If Ampere : V x 230 = VA
Ex : 7.5A x 230V = 1725 VA
If Watts : V / 0.7 = VA
Example for a GGM KITIP24C5MP or GGM NVRL0104P
| No IR | With IR | |
| No Camera | ~9W | |
| Add 1 Camera | 13W | 15W |
| Add 2 Cameras | 15W | 18W |
| Add 3 Cameras | 18W | 21W |
| Add 4 Cameras | 21W | 27W |
For 2 cameras : 18 / 0.7 = 25 VA
Example for GGM KITIP48C5MP or GGM NVRL0108P
| No IR | With IR | |
| No Camera | ~10W | |
| Add 1 Camera | 12W | 15W |
| Add 2 Cameras | 15W | 20W |
| Add 3 Cameras | 18W | 26W |
| Add 4 Cameras | 21W | 31W |
For 4 cameras : 31 / 0.7 = 44 VA
