Used system.
I bought this new from Amazon, installed and then removed when I moved house.
I messed around with some cables so only able to be connected via a WiFi network (as apposed to Ethernet).
The Box has built in memory and it was set to a 30-day loop (i.e. it deletes automatically deletes after 30 days).
Cameras and Cables a little tatty.
Collection from Henleaze, Bristol, BS9.
Happy to accept offers if you don't waste hours of my time asking how it works. It was working when I removed it and there is no reason why it wouldn't work now but it has been left in storage for 12-months.
