Home security... Cameras

[Rod200SX]

Had some odd events at ours. We live in a wee estate which is across a river from a not too pleasant area. We've noticed things like doors being tried, side gate open etc in the past but over the weekend someone has been in to the back garden and by the looks of it, been sat smoking finished tabs from the ashtray by one of the back doors.

Now that itself is, whilst harmless, really quite unnerving.

We've thought about cameras but don't want a full on cctv system. Has anyone got any experience with any wifi cameras? My question really is whether there's anything out there that would do motion sensitive alerts?

Ideally I'd want one at back door & one at front door. Both of which could be covered through windows on either side of the office.

Also legally what would be required as to signs etc? As they wouldn't be pointing out on to the street at all.

I've popped a crap pic up of the house showing where the door is (X) & where the gate is.


Apologies if this is badly written, I've had about 8 hours sleep since Friday!
