We have a 4 camera sysem for afew yers now, didn't connect the barn one up, had some scaffolding stolen, OH connected it up straight away, as the camera gives off red glow from the infra red we presume that now discourages people.
Also bleeps when a vehicle come up the lane, so if I'm on the computer in far room I can still see if they stop without me having to go to the door.
Also occasionally (??) I can't remember where I've put things, run foootage back I know which direction I carried it last (ie expensive camera on Sunday, at least I knew I'd taken it back in the house!
)
Did have one covering top of field/lane, but camera transformer has gone, this has reminded me to look for another while online.
I like ours. but probably better and cheaper now.
