Portable solar car alarm

[mojoman]

Put this together rather than connecting to vans system.
Has a siren, car horn, lithium battery, solar panel, usb plug,12v plug.
It is set up as a proximity alarm with remote alarm pager.
It can be powered by the lithium battery and solar or 12v cigarette outlet.
Can be used anywhere.
Haven't tested the maximum distance of the pager yet.

Is that picture tipped side ways?
Not trying to be smart@&&. ('cours it happens without out trying).
I like the idea, like to know more about it & where mounted in R.V.

I set it on the counter or dash. We also plan to use it at outdoor events where my wife sets up a vender tent to keep the riffraff out over night. Its an Excaliber unit with remote paging mounted in a lunchbox. No other sensors or inputs other than proximity are connected to it. If you set it under the van at night it will alert you to anyone walking around your campsite.
Seems all my iPhone pictures end up sideways when posted.

I made one out of an old mercury thermostat, 9v battery, light and 12v buzzer.
All it did/does is make a noise and light up when someone pushed on the vehicle (most thieves apparently try to set off an alarm by moving the vehicle).
Rudimentary but when set right makes a person think twice about doing much more and shuts right off when the motion stops.
