Wireless Security Alarm

At my parents I need a alarm system on my bedroom. I would need it to be wireless, easy to install, and under $50. It can be used

I need 1 door sensor, 2 window sensor, and a motion detector would be nice.

PLEASE HELP!!
I WANT A SECURITY ALARM! NO CAMERAS!

I want to set up an outdoor video surveillance and need to know what I need.

1. Need a wireless, solar camera because it will be installed 500 ft from my house. Do they have these?

2. Need an Internet camera that broadcasts on the Internet and saves the images so I can view it while working on the computer.

3. Night vision because there are no street lights here.

Please tell me which online stores have them and step by step instructions if possible.

Recently moved in to a newly built home in a rural area, right next to a busy road.

Recently I’ve noticed weirdos stopping in front of my home and taking photographs of my property. When I go outside to let them know I can see them, they take off.

At nights, there are strange cars parked on the road with their headlights on near my home.

I have expensive new cars parked on my property so I am thinking they are planning to carjack them or rob my home.

So far I’ve:

Installed a fence around the property.
Got a large dog that bark at strangers and will bite if they happen to jump the fence

Which is the best wireless security camera that works in the total darkness (there are no street lights here) and that can be broadcast on the Internet?

I have a chain linked fence only, so what can I do so they can’t see throught it?

Any other ideas?

Installing the cameras, sensors, wires, etc and then connecting it all to a main computer and then set up the wireless alerting devices - notifying you and then the police department? Is this a difficult project but worthwhile since there is no need for a monthly fee that you pay with other security systems?

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!!
