Home Security Alarm
Home alarm system ideas
Relying on attentive neighbors and basic safety practices is not always enough to guard against burglary, fire and gas leaks in your home. Setting up a home security alarm system can help you to protect your family from unforeseen hazards, discourage intruders and gain instant access to emergency support. Before purchasing security features for your home, it is important to know what types of security alarms are on the market and the protections they offer your family.
Types of Home Security Alarms
While the traditional burglar alarm is most common, a home security system can also incorporate sensors that detect carbon monoxide, smoke and fires, flooding, and other home hazards. Sensors are designed to respond to specific conditions, such as excessive heat or body movement, causing the alarm to be triggered. The alarm itself may be a simple siren (with or without warning lights), an automatic emergency call or an instant signal sent to a 24-hour help desk.
The effectiveness of individual detectors depends on their complexity and sensitivity. The most inexpensive sensors consist of foil tape forming a circuit, which breaks and triggers the alarm when an intruder breaks a window. However, false alarms are more common for such sensors, which can be disturbed easily by accident. Other options include magnetic switches that respond when the circuit connection is broken and audio discriminators that react to the sound of glass breaking.
Sensors that are targeted towards open spaces utilize more precise methods, such as passive infrared technology that detects heat fluctuations and ultrasonic sensors that detect high-frequency sound. The best detectors use dual systems that trigger the house alarm only after both infrared sensors and microwave detectors sense a shift in the room's conditions.
Setting Up Your Home Security Alarm
The type of sensors in your alarm will depend on the specific security zones you choose to target. Mechanisms like foil tape and magnetic switches are types of perimeter sensors, which are attached to walls and exterior doors to identify an initial entry onto the property. The more advanced infrared, ultrasonic and microwave sensors can protect open spaces like rooms and hallways, and may be triggered even when the perimeter sensors are evaded. However, when using space detectors, it is often necessary to equip the area with several sensors pointing in different directions in order to receive full coverage.
Setting up a security alarm usually requires wiring to connect the sensors to the annunciator (source of the siren) and the control panel. A wireless home security alarm bypasses this step and requires drilling only to mount the control unit.
Instead of waiting for disaster to strike, purchasing a home security alarm allows homeowners to take active and preventative measures in protecting their lives and property. In addition to setting up a security system, always remember to use practical responsibility, such as locking windows and doors when necessary and changing the batteries in smoke and carbon monoxide detectors. If you stay one step ahead, you'll be prepared in times of danger.
