I'm planning to set up security cameras around the perimeter of my house. But I'm confused about what type of system do I use.

Don't think wireless cameras will be good, considering even wireless requires a power source. For me, it's more daunting than the inconvenience of cables. I'm already using a monitoring system but they quoted an insane installation price and monthly fee.

So, I searched on the web and found a good security camera company in Toronto. But before paying them, would like to hear your suggestion on this.

Can anyone provide some guidance as to alternatives?
