Wireless Security Alarm

I am interested in installing a wireless home security alarm as they are easier to install than wired. Are they any good? Which are the best makes? Any negatives to be aware of?

I am looking for a wireless home security camera I can place in a window. I have read some reviews and cannot find one that is good in low light that is in my price range. I would not want to spend more than $300. Does anyone have any suggestions? Thanks.

(sorry for the caps, I just wanted to catch attention because this is an urgent question).

Recently three apartments in my complex have been broken into, and they were all robbed. So far, nobody has seen the perpetrators.. so they are out free and breaking into homes whenever they catch the opportunity.

I know some people are thinking “Just get a big dog”, but I cannot. I am expecting my first child in May and I cannot afford, spend the time on, or find a dog that will be great with an infant and be low maintenance as well as a great guard dog. I looked, but in the end I was not able to find a dog that would be good for my family.

Anyway,

If anyone knows any great wireless alarm systems that do not cost very much (no more than $80), are VERY loud, and would be great for doors (mostly the front door).. PLEASE let me know.

Thank you very much.

(ps. no rude or sarcastic comments please. Also, I am not shouting when I use caps.. please do not get offended.)

Ok so we are moving next month into a house that we will be renting. Unfortunately, ADT & Brinks dont let renters use their services…which is ok because we dont plan to rent the house forever, so their products would probably be a waste of money anyway.

Ive been online FOREVER it feels like, looking for a home security system we can install ourselves. Ive heard wireless is the easiest way to go? We just dont want to have to pay a professional to come out and do it. I have NO idea how to find what Im looking for or what products actually do what we want them to do. So Im hoping that maybe somebody can steer me in the right direction if I describe what I hope to find…..

Like I said, wireless would be great. I want something not too difficult to use….we would like to be able to monitor all the windows and doors in the house (there isnt very many). And MOST OF ALL, I want something LOUD. Id want the siren/alarm to be able to be heard from the next door neighbors houses….I figure, if the alarm isnt very loud, what good does it do? Im hoping that if (God forbid) anyone ever tried to break in, the alarm would scare them away if they know everyone can hear it and cops may very well be on their way….

I have a 4yr old son and I want to do anything I can to assure a sense of safety in our house.

Any info or help would be greatly appreciated. Does anybody know of a system that I should purchase?

THANKS IN ADVANCE!!
