This home security product are door alarms.  You have basically two choices when it comes to simple, do it yourself door alarms.  The first type of door alarm is a small device that simply hangs on the doorknob of the door that you want to protect.  This type of door alarm works by sensing motion.  If it is perfectly still and not bumped, the alarm will not sound but if it is moved at all a very loud piercing alarm will go off.  This will not only scare off any potential burglar but it will also provide you with the peace of mind of knowing that if you are home alone you’ll get for warning if someone tries to break into your home.  These hanging door alarms are very inexpensive and obviously easy to install since all you have to do is hang them on the doorknob.

The next door alarms are a little bit more complex but it’s still fairly easy to install.  With this type all you have to do is stick two magnetic sensors on the door and doorjamb in close proximity to each other with the supplied double stick tape.  Once the alarm is activated, if the door is opened it will break the signal between the two magnetic sensors and the alarm will sound.  This type of door alarm is a little bit more expensive than the first type but it’s not out of the reach of most homeowners.  Sense it can be installed very easily in a matter of just minutes, it’s a good alternative to not having an alarm system at all.  This type of door alarm usually has an on/off switch or a keypad that enables you to enter a code to arm and disarm it.

If you don’t have a burglar alarm system installed at your home, do yourself a favor and invest in some door alarms.  They will provide you with much greater sense of security and help prevent you from being a burglarized.

• Signs and Stickers: The first, and I think most important element in an effective burglar alarm system are signs and window stickers.  If a burglar breaks into your home not knowing that a burglar alarm exists, they may leave and not steal anything but they will have likely already caused damage to the home that will cost you to have repaired.  Signs in the yard and on every window will inform a would be burglar that your house is NOT an easy mark.  A common mistake is to only put alarm warning stickers on the front door or the windows on the front of the home.  Most burglars will attempt to enter from a side or rear facing window or door.  You should have stickers on these doors and windows as well.  For businesses, outdoor led signs that warn thieves can really draw attention to the fact that you have a burglar alarm system
• Door and Window Contact Sensors: The next critical component is door and window contact sensors.  These sensors will cause the alarms to activate should any door or window be opened while the burglar alarm is activated.
• Glass Break and Noise Sensors: Should a burglar break a window and climb through, the contact sensors may not be activated since the window isn’t actually opened.  Glass break sensors will activate the alarm if the a window or glass door is broken.
• Motion Detectors: If an intruder were to get past the first three elements, it’s important that the home be equipped with motion detectors.  These can be strategically located in the home to cover the most traveled areas.  With modern detectors it’s possible to buy pet friendly units.  Many times a home owner neglects to activate their burglar alarm because their family pet might set the alarm off.
• Control Center: The control center ties the entire system together.  Here you can program the various elements such as passwords, alarm zones, and alarm activation.
• Video Cameras: Hidden video cameras can be instrumental in catching someone who tries to burglarize your home or business.  The burglar alarm can stop them but the video camera will put them behind bars.

Whether you install your own system or have it professionally installed.  Be sure and utilize all of the elements of an effective burglar alarm.
