The Reject shop is selling a Video Camera for $39 that connects to your 'smart phone' via Wifi.
As an aside, the system supports PAN and TILT !!!
It also has Hear and Speak audio which you you can turn on and off.
It must be connected to a typical 5 Volt supply by a USB cord.
No 240V/5V plug pack supplied.
Motion sensor and Night Vision.
Takes up to a 32 GB micro SM card for recording on.
No mention though if it just records and stops when full or wipes previous recorded material.

Well, I drove my self sillier yesterday trying to get the two connected.
After many many futile and frustrating attempts I did manage to get a picture on the phone and made the camera move Pan slightly (5mm) and then lost the bloody lot.

You have to go to Playstore (android) for the software but which one?
I chose one of the two called 'Motorized Camera' which I have now deleted and going to TRY the other one listed and see if I can get THAT to work.

Note this Camera isnt intended to work like the one on TV that rings your phone when your away so you can see and hear who is where ever you have the Camera installed, the Front Door for instance.
The Camera and SMART phone must be within WiFi range to function.
That could be handy in some situations so long as you can power up the camera.

Anyway, I will download the other program and see if that works any better.

I do wonder why I get into things I know damn well are smarter than me.............
