A UPS (Uninterruptible Power Supply) battery backup device can ensure your CCTV system remains working in the event of a power outage.
Following our research, the VA figure provided with traditional UPS units actually provide no indication as to the actual capacity/run time! (It is just the load at any given moment) – they usually have small lead acid batteries (Approx 30 watt hours useable for a £100 UPS and 60 watt hours for a £200 model) - The maths: an average 4 camera kit consumes up to 40 watts so you are looking at just under or just over an hour of run time with the above. (As a rule of thumb it's a 5 watts per camera difference so add 20 watts for an 8 cam camera kit, all based on a single HDD)
The VigorPool UPS stations use Lithium Ion batteries which should never need replacing in reality and offer superior backup times, the Captain 300, which costs £298 and provides 177 Watt hours via the inverter (25% power losses taken into account); so whilst costing 50% more it provides 3 x the backup time with 4+ hours for a 4 camera kit!
The captain 700 would provide 12 hours, or about 8 hours backup for an 8 camera kit, whilst the Captain 1200 should deliver around 9 hours of battery backup with a 16 camera solution!
