Hi guys. Would like a narrow beam across drive that I can set about 3 feet above ground level which I can connect to my WiFi and get an alert off a spare phone I already use for overnight car alarm activations via an app.

I have suitable bushes either side into which I can mount a transmitter and receiver.

All suggestions gratefully received.

Cheers

That part is easy, the receiver is usually mounted in the transmitter, with just a reflector at the far end. I use one across my garage roller shutter door, to prevent it closing onto an object. It also lights an LED mounted in the far end of the garage, so I know I have driven the car in far enough, to clear the door.

It has NO/NC voltage free contacts, so would be easy to interface to almost anything, even a wireless doorbell.
 
Can you get a power cable out there? Any sort of beam will need a permanent supply
 
I have a good router and network switch. I also have an alarm but would prefer it to be separate with a notification to my phone.

If the beam is triggered, you're going to want to know what it is.

Maybe a camera with motion detection to start recording and issue an alert?

I got one when we had a neighbour who sadly got dementia and used to roam about uprooting things.
 
Some wifi security cameras, include a facility to trigger a warning message, plus recording a short video when trigered - maybe worth looking at?
