These UPS Battery Backups provide you with battery power if the power is lost for your cameras, allowing them to run even when there is no power for a period of time. However, the biggest benefit of these hand-selected UPS units, is the AVR (Auto Voltage Regulation). There are tiny micro pulses and drops inherent in commercial and residential power, the Auto Voltage regulation uses the internal battery to supplement when their are drops and bleed off excess voltage when there are spikes to provide you equipment with proper sine wave power at the correct voltage all the time.
In our studies, we have found that there is a direct correlation between the cleanliness of the power into your DVR, NVR, PoEs and cameras with the longevity of the cameras. This is why Platinum CCTV equipment now requires connection to a UPS that has AVR for the equipment warranty.
