The system you choose should depend entirely on your needs. Personally and professionally I would strongly recommend against wireless security systems. The reason being, the technology is flawed by nature. As a last resort, I guess it is better than nothing if it is impossible to run wires. However, in almost 20 years in the industry I have never seen a job where wire runs were impossible.

I know choosing any product or service can be difficult if the technology is foreign. I find a little simplification of alarms in general can be of help to clients. An alarm in its simplest form consists of a control panel similar to a computer, which has sensors connected to it (window contacts, motion detectors, glassbreak detectors, smoke detectors, carbon monoxide detectors etc.) The entire system is controlled by a keypad. How the zones react and what signals they send to the monitoring station is entirely programmable.
Choosing who installs your system, well now that can be about as fun as a root canal. I would suggest you ask around locally, try to find a company which is small enough to care but big has been around long enough to ensure you will continue to receive the service you were promised. I would avoid "Authorized dealers" as this typically means they sell their monitoring accounts to the host company. I really hate it when consumers are treated like commodities. I have written a little bit about choosing an alarm company in the false alarm section of www.keepsafesystems.ca.
Aside from electronic security, there are several things you can do in and around your home to make it less inviting to the crackhead sector of society. Once again, feel free to check out protection 101 at http://www.keepsafesystems.ca for a little more information on securing your home.
I know I really didn't give you any specific companies, but I hope this will help you in your decision making process.
