Yeah, if he want's to feel safe that I'm not robbing him, he can buy two wireless surveillance cameras for $100 and point them at each door.

I heard in one if the BP podcasts there was a wireless water meter that was easy to install and I cannot find the podcast again.

Depending on how many properties you have, it could be worth looking into something like the Monnit wireless temperature sensor.

ideally I'd like an alarm that operates on a cellular signal and is essentially a wireless system that I could move from property to property.I've found the 'tattle tale' system but it seems kind of pricey, are there any others you would reccomend?

Aloha,Assuming you have some type of alarm system in the property, you should fairly easily be able to come up with a temperature alarm that could reside IN the refrigerator, and communicate with the alarm panel via battery wireless.

It is not the most cost effective, but they have remote wireless signals (no need for internet connection) with battery backups and remote viewing capabilities. 

It was all wireless and uses self adhesive back to mount.I think you can order a basic system for around $300.00

The wireless solution is not working well - batteries dying too often and complains that the bells just don’t work.  

I have been using my iphone as a wireless hotspot to run my ipad and my wife uses her iphone to run her laptop.
