About Some Simple Door Alarm Systems
There are different kinds of battery operated door alarms which a person can now install into the doors of their home.
These work on the principle that, as soon as the door is opened or has been forced open, then the alarm goes off. Certainly, once it has been triggered, it is loud enough to wake up anyone inside the house, and is also a great way of scaring off the burglar.
It is important, however, that the alarm you do install is a good quality one, and will work for extended periods of time. Also, you should only use high quality strong batteries in the alarm so it remains functioning correctly. Unfortunately, a battery that is dead will not keep the system working properly, and in fact, the system will be completely useless, and this is when the burglar will have more opportunity to gain access to your home.
There are now also ultrasonic alarm devices available for doors which, although are expensive compared to the battery operated ones, are very effective indeed.
This particular type of alarm is placed in the corner of a room and it contains a transmitter and receiver, which then saturate the room with ultrasonic sound waves. These waves bounce of the walls in every direction, and when these waves then are broken, the alarm is triggered. This particular system, once triggered, can then turn a light on, or sound an alarm, or do both at once.
You may also want to consider a wireless intercom unit in your home, as this allows you to hear certain key noises as they occur around the home. Such systems often require no wiring to take place, and usually they can be plugged directly into an electrical socket in any room in the home. Also these systems allow a person to communicate with other people in other rooms in the home, as well as allowing you to hear what is happening throughout the home. There are various different systems now available, and as mentioned, some do not need wiring (they are wireless), while others do.
The great thing about many of these systems is, however that they are pretty inexpensive, and quite easy to install. If you are unsure about what you are doing, and where exactly you should be installing them, contact a very reputable home security service, and they should be able to provide you with the assistance that you require.
