I recently stripped out a caravan and turned it into an office and I thinking about how I could alarm it.

It has power and network but it seems a waste to use a raspberry pi. An ip camera might work, but my main concern is how easy it is to cut the power before entering the van. I just need something to wake everyone up if something tries to get into it. I switch my mobile off at night but during the day it would be cool if it did video though a webpage.

Anyone have any ideas ?

Cheers

Install a cheap DIY (audible) alarm kit with a small UPS. Both would be Dick Smith items.
Every office should have a UPS anyway.

I installed a simple wireless alarm kit from Jaycar Electronics a few years ago. Basically just a code panel with a siren in it and a few door / window magnetic switches, all using AA batteries. Very easy and worked well (when the house owner remembered to use the code and turn it off before the alarm started!).

Of course it depends on how much you want to spend. You could add things like window break detectors, movement detectors (if someone tries to tow the caravan away), etc.

Or, you can got the cheap route and install a fake camera.

I guess having a United Parcel Service worker sitting in the office 24-7 would work, but could be expensive. ;-)

I've got a similar thing from JayCar, it works great

It's powered by the mains, but has 9 volt battery which kicks in if the power goes down

I'll need a rocking chair out the front, a spittoon and a piece of straw :)

I'll check out Jaycar to see what they have.

Nah, just wire the whole caravan up to the mains ... anyone touches it an "ZAP!". ;-)

Dick Smith will probably have similar systems too.

Also dont forget Ebay. Recently bought a new alarm that way. All wireless. Panel had backup battery. Also sends out SMS if power is disconnected or alarm is triggered.

If you are really on a budget Ebay has SMS enabled PIR sensors for about $20 which are all self contained.

Yeah most alarms (like paragon? etc) have a sealed 12v 7ah battery within them that will run the alarm system for a few days if there is no power.

Personally I would go for something like this on trademe
http://www.trademe.co.nz/home-living/security-locks-alarms/doorbells/auction-708594912.htm

But look for a smaller kitset that doesnt have 2x code panels, or multiple sensors. You really want to just see if you can get a glass break sensor, a door sensor and a single infrared motion sensor

On trademe they also have ones that will txt you.

Dick smith for years used to sell all-in-one wall mounted ones - they would also be ideal and I think jaycar sell them too now.
You just have two remotes like a car alarm and its got AA backup batteries / siren within it so you just mount it on the wall. The important thing I would stress with these and wireless ones is that you make sure you can mains power it - replacing batteries is a pain in the a$$

buy one of those TK103b GPS tracker units. that way if anyone breaks in you'll have a text within 5 seconds.  easy to hook up and works just like a car alarm. hook up a shock sensor or microwave sensor and a door switch just like a car. runs off 12v so have a battery somewhere and maybe even charge it via one of those solar panels
