We can't see the mailbox from the house - it's down at the end of a
fairly long drive. I'd like to know whether the postie's been, without
having to bundle up and slog down the drive in winter weather - it would
also be good to have at least a little warning before guests drop in.

Ideally, I'd like more than one sensor - one perhaps _inside_ the box,
so passing sheep, cattle and cats don't set it off, and one part-way up
the drive (above cat level), as a drop-in-guest-detector.

Wireless, of course, with a plug-in receiver.

Anyone here have useful experience of such things?

Eeek!
The Amazon _UK_ price is highway robbery!
I wonder what US airport security would think if I packed that in my bag...

I hadn't realised that I could do that, thanks. I normally just buy
in the US.

Well not exactly ;-)
I read about one being hacked with a raspberry pi to do emailed
alerts with pics so I bought one from US Amazon (dvd to UK) but
not got tuit yet...

Let me know if/when you do.
(Now I'll need to buy a raspberry pi, too.)

I'd run a cable down with a cctv camera in the box and a pir sensor
across the drive with a buzzer in the house. Wirless means having to
build in solar charging, which IMO is always unreliable in winter.

Easier to install wireless, though.
The soil is very rocky - The previous owners had to use explosives to
clear a way for the drive.

If you have a drive, it's easy enough to angle grind a channel for
a small cable, you only need one wire for supply, as the return can be
through the ground IME. Just need to adjust the drive voltage to ensure
enough power. Then you may want to use wireless for the signal or add a
couple of wires for twisted pair video linkage, these are good for 200M
I understand.

It's a LONG drive, and I have other things I'd rather spend the time and
effort on.
It will be wireless.

This is where those cheap Chinese lasers could come in useful. You could
criss-cross your driveway/paths with their beams like something out of a
James Bond film. Photodiodes to detect interruptions and away you go.

I wonder how much you could generate with one of the beam lasers
used to blind pilots? Need a parabolic collector I guess to optimise yield!

Trouble is that in his case it would be impossible to distinguish between
cars and cattle. Easy enough to distinguish between cats and the rest tho.

I have these:

Hooked up to a mixed X10/Insteon system.

The Luminite stuff is pretty good, but expensive (imo). Linking it into
Home Automation (HA) is initially simple, but becomes complex depending
on what you're trying to achieve.

I've got a number of Niteguard PIR's protecting a roof and hooked into a
burglar alarm, occasional false alarms from birds (two or three magpies
squabbling normally - I've also got CCTV!), PP9 batteries last at least
a year sometimes two (if I forget to change them). Been in service for
nearly 10 years.

One would fit inside your mailbox, but aerial would need to be outside
if box is metal.

1. I found that the easiest way to have a nice-sounding chime that
warned of a visitor was to feed a bog standard ding-dong door bell via a
relay. You can have several different chimers from the same unit if you
have several IR beams.

2. If you use CCTV don't try to get two camera signals up one CAT6.
There's crosstalk. It's unworkable.

This place has one. Pigeons delight on alighting just in front of it,
and cats walking up the drive also set it off.

To be fair, a car always does.
