How to make a home security electrical circuit.?
Hi, i'm trying to figure how to make a home security circuit. I can't figure how to make a buzzer go off if a door/window is opened. Am i right in thinking i'm going to need a parallel circuit with with 2 resistors with a higher resistor above the door (higher resistor meaning with more resistance) and a lower resistor on the door for when the door's closed. Thanks
Depends on how complex you want to get. The easy way is with magnetic switches. The switch is next to the magnet when the door or window is closed and in the open position. When the magnet is moved away from the switch because the door or window is opened, the switch closes and the buzzer sounds off. Each switch would be on it's own parallel circuit.
For a little better security, wire the switch so it is closed when the door or window is closed. The switch opens when the door or window is opened, releasing a relay that then closes to activate the buzzer. This way, you get notified if the circuit is cut.
There are many more ways, some actually measure the resistance of the circuit and alarm if it changes, etc.

Home Security Systems
How do I determine what is the best home security system?
I have bought a new home and am concerned about rising crime incidents in my area. How do I determine what is the best home security system for my particular place?
You should get an estimate for your particular home by contacting a security expert that lives in your area. There are a lot of scammers out there who are running "security companies" out of the trunks of their cars and with cell phones. You want a company and an installer who is local to you, is licensed and has good referrals. You want to look through their site and see what their Better Business Bureau rating is.
If they are registered with the BBB ( a good thing) and their rating is good, you will see this "BBB" logo somewhere on their site. Ideally, you will find someone with an A, or better yet, A+ Rating.
My company, www.MulhollandSecurity.com, is such a company. My policy is to do the best for the customer -- we don't let anyone go away unhappy.
There are so many variables in home security systems that you need to have an expert on your side who has a record of acting in the best interests of the customer. When you see that high BBB rating, it basically means that they are doing their best for the customer: getting the best equipment for the budget and making sure the installation is correct.
Some of the slickest websites for home security are not really home security businesses. They are websites and toll-free numbers that take your information and then sell the lead to a locksmith in your area.
I would suggest you find these qualifications: website. high BBB rating. and lots of referrals on their site. Call and make sure that they are local company with a real office or shop.
A person like this will not steer you wrong in deciding the best system for you. He is concerned with his PR and reputation enough that he will do the right thing with you -- get the best and most appropriate system at the lowest price.
