There was a time when security systems and home burglar alarms were only found in the homes of the rich. With the advancement of technology however, prices have fallen enough so that ordinary people can afford to install in their homes. There's even an option to buy do-it-yourself systems that come with everything needed to install it.

You may select have a cable or wireless system, activating the alarm when an intruder tries to open a door, or when there is a movement indoors while the alarm is armed.

More choices … open circuit or closed circuit. With a closed loop system, when you open a window or door, the circuit is broken and the alarm goes off. As expected, an open circuit system works the opposite way, if completed the circuit when a door opens and the alarm is disabled.

As the name suggests, motion sensors can sense when there is no movement within a certain range of it. When it detects motion, send a signal to the control panel that will analyze it and determine whether it is a kind of suspicious movement or not. The control panel will react by creating of an alarm or notify the authorities if it is decided that the movement is suspicious.

To reduce the chances of a false alarm, sensors movement can be configured to ignore the movement of pets or walking around the common activity of others in your house. Motion sensors are becoming increasingly common and is a great way to protect your home.

The ideal situation would be to have a combination of magnetic switches on the door and windows and sensors movement within the halls and corridors. The other two options that make up a complete security system is to add a video camera system and, eventually, have a firm that control security system for you and provide a rapid response service.

AquaGuard Inground Pool Alarm System $469.99 The AquaGuard Inground Pool Alarm System detects a child, pet, or object with a minimum weight of 18lbs (8kg) falling into a pool or spa. When the alarm is set off, a siren sounds at the main unit by the pool and in the wireless remote inside the house.AquaGuard technology has been extensively tested to the most rigorous standard for pool alarm in the world (AFNOR) as well as the U.S. ASTM standard. What all this means to you is that the system features excellent performance combined with the highest immunity to wind and other surface disruptions for consumer installed pool alarms.AquaGuard incorporates the latest advances in volumetric displacement technology. When a child or object falls into the pool, AquaGuard accurately measures the amount of water being replaced. If the water displaced is more than 18lbs, then the system triggers the siren to alert the homeowner. The AquaGuard Pool Alarm System provides ease of use and intuitive "messaging" that lets you know the status of the system. When you want to use the pool, you simply enter your access code at the main units keypad or with the wireless remote, putting the system into "swim stand-by".A short while after everyone has left the pool, the system will automatically re-arm. We felt that it is very important for you to know when the system is armed or in "stand-by" mode or if there is a low battery. For this purpose the main unit has a large red visible LED on the rear unit which tells you exactly that and the wireless remote does the same. Whenever the system re-arms you will get an audible via the main unit and wireless remote.Each AquaGuard Pool Alarm System includes a main unit (detector) and a remote unit with an AC adapter.One AquaGuard Pool Alarm system will cover a typical 32 X 16 rectangular or kidney shaped swimming pool. If the pool is larger or irregular shaped, then you will need 2 systems (consult your AquaGuard dealer or us directly with questions). When using 2 systems, they can be operated via one wireless remote for ease of use. A spa will require a separate system.
