It is the only explanation of how I solved a mystery.
 
One of the CCTV installs I did recently has been giving me some headaches.
Between 3.00am and 8.00 am the DVR unit has been stopping and rebooting many times in the night.
The rest of the time it works fine.
 
I just couldn't work out what the problem was.
 
I woke this morning with the cause and solution in my mind!
 
This unit is based in a pub, and specifically in a area to the rear of the pub which houses the Fridges, Freezers, Washing Machines etc.
 
During the day there is, just, and adequate power supply, however, at night the lights go off and the cameras switch over to IR.
That in itself puts the draw on the limit.
But every now and again a fridge motor starts up and the tiny extra load for the start up (not for the continuing running, merely the start - ask an electrical engineer (of which I am one from a previous career)) is enough to drop the current to the DVR, even momentarily, but enough to force a reboot!
 
I am running the DVR (1.5amp), The Monitor(1.5amp),3 x Power Supplies for the Cams (3 x 4.5 amp(max load)) (Total 16.5 amp) off a single spur at 13 amp. (Within the tolerance of a 13amp fuse, but still 'Hot'.
 
Of course this is then susceptible to line noise and current changes as the other equipment on the line is heavy.
 
Solution?
 
Run another spur off the ring to just power the DVR!
 

 
But this all appeared as a complete solution in my head the moment I woke up this morning.
 

 
Damn I am good!
