re: Wifi Home Surveillance Systems

There are some decent wireless cameras but as other pointed out, you need power to them. So it's typically easier to run cat6 and use poe.

With all that said, the only thing cameras will do is allow you post grainy footage on Facebook and ask if anyone knows the guys breaking into to your house. I say this as a guy that has a home surveillance system but the best methods to keep people out are obvious.
- Lock vehicles (park in the garage if possible), not only have alarms on the house and vehicles but actually use them.
- Leave exterior lights on at night
- if you do have cameras, make them very visible to the thieves. They go for low hanging fruit and will pass up your house to rob the one without the alarm and cameras.
