security system while renovating

[Joe Sadusky]

Hi Guys, 

I'm looking for recommendations on security systems and cameras for vacant houses that my team is renovating.  We had our first break-in and all of the copper was stolen. 

A security system & camera that does not need internet/wifi would be preferred (works off cellular network). 

Also looking for the system to be easily transfered from property to property. 

Thanks in advance for any suggestions!
