Alarm Systems


In its simplest form, an electronic alarm system is a low-voltage electrical circuit with sensors on entry doors and windows. When a door or window is opened, its sensor detects the interruption in the flow of electricity and triggers a warning signal such as a siren or strobe light.


In addition to perimeter sensors, many systems also include motion detectors that monitor large areas inside the house. When something moves within the detector's range, a sensor sounds the siren. The most sophisticated motion detectors are able to distinguish between the threat of an intruder and the nocturnal wanderings of the family pet, reducing the possibility of false alarms.


When these perimeter sensors and interior motion detectors are part of a stand-alone system, the siren and flashing lights are the only deterrents for discouraging the intruder and thwarting the break-in. In a monitored system, operators at the system manufacturer's central station also notify the police.


In order to choose the best alarm system for your home or workspace, consider the following options:

  • 1. Electric Current Alarm System. This is a basic monitoring tool that only monitors entry points like doors and windows, and often installed when a home is being built. When installed, a low-voltage electrical circuit flows between two points and if doors and/or windows are shut, the current flows easily. But, if they are opened, the circuit is disrupted, and an audible beep is triggered.

  • 2. Wired Alarm System. The wired security system relies on your landline phone connection to transmit signals to a monitoring center. Though it supports basic monitoring capabilities, it is vulnerable because physical onsite wires can be cut or destroyed, thereby, rendering the system ineffective. However, cellular backup is recommended to prevent weather and/or other landline interferences.

  • 3. Wireless Alarm System. These are alarm security systems without wires. These alarm systems typically use a control panel and a series of sensors that are connected with built in radio frequency transmitters. Once the alarm system is triggered, a signal is transmitted to the control panel and the alarm is activated. Its benefits include allowing for remote system management through mobile devices, and integrating with other smart home functionality like lights, video surveillance and thermostats.

  • 4. Unmonitored Alarm System. Also known as “local” alarms rely on you or a concerned person near your home to alert the authorities of an emergency. With this system, when tripped, audible and visual alarms are triggered. Unmonitored systems don’t provide the same level of protection, as they do not notify a monitoring center of your emergency for subsequent first responder dispatch. Even if the alarm sends an alert directly to your phone, you may be unable to respond if you have bad cell reception or are away from your device.

  • 5. Monitored Alarm System. Having a trusted professional looking out for you is always comforting. A monitored home alarm system helps ensure that authorities are notified quickly in event of a break-in 24/7/365. This is because monitored alarm systems alert both the homeowner and monitoring center operators when an alarm is triggered.
