Do you know what happens in a blackout, or when an intruder turns the power off?


NO power to your house or business, means no power to your cameras, or recorder, or router.  The whole system is “DEAD”.   So the camera security protection that you were relying on to protect you, doesn’t!

Unless, of course, you have a UPS (uninterruptible power supply) to keep everything working.

When people get quotes for CCTV camera systems they are often price conscious, and the UPS is left out of the quote to make the quote look more competitive.  The extra expenditure on a UPS may seem unnecessary, but when the power goes off, you’ll be very glad that you have it.

What’s so good about a UPS?  The UPS contains large rechargeable batteries inside it, continually being charged by the mains power.  When there is power loss, the electronics in the UPS convert low voltage battery power to normal house hold power to run the system.

If your CCTV camera system is a key part of your security, then this is an essential addition to maintain your protection equipment so that you don’t lose vital video footage, get a good UPS.
