Used to be a necessity on the older units.

Kicker was sites with backup generators. Genny kicks in, Hard Drives stuffed. Intellex were very susceptible.

agreed

even if you dont fit one, at least recommend one.

tbh the Maplins units i find pretty good for the 'bread & butter' systems at the price, generally always available reasonably locally and way better than any anti-surge extension lead.

really, on smaller budget systems your looking to protect against the short 'flick' power downs, as to protect against say an 8 hour outage, add in the cameras and your going to be paying the big bucks that shopping centers might command.

but does it have IEC sockets ?

used to use belkin, but they appear to have vanished from the market so on with APC

sure its gone up a tenner ?

handy to have std outlets to bang a 13amp plug top

After testing a few brands we now only use APC. Usually a CS unit

no probs with that, for CCTv and PABX needs you rarely need more than 5 minutes standby.

cheap CCTv on a power down will usually mean cameras are dead anyway unless powe4ed from the DVR, so you looking to make sure the DVR is protected for when the power restores, PABX 5+ mins is enough to call the emergency service and/or evacuate staff for a suspected bomb scare for instance.

so a budget unit from Maplin will be fine for that need, obviously increase for the jobs that need it.

iirc the smaller Maplin units they have 3 x13 amp socket outputs, but only one socket is maintained. so the 'trick' is to use an extension lead if you need to power the PSU's as well.

just to add, these units carry a hefty indemnity insurance for any damage not prevented from EMF or Lightning
