I may be stating the obvious but cameras are only going to record the crime. It would be best to harden your security. Always, and I mean always, keep everything closed and locked. You neighbor who said they were going to put the slider bar down... they should be doing that whenever the slider is closed. It's not doing any good sitting next to the door. Keep ALL windows closed and locked. You may think you're safe but someone who has the time is going to circumvent your entire property and look for the weakest link and exploit it.
