The Wireless Alarm
A wireless alarm is different from a wired alarm because the communication between the control unit and the detectors is done by radio waves. Indeed, as the name suggests, the wireless alarm does not require any power cables or wires to communicate. Wireless alarm systems have many advantages and their reliability has evolved. Although wireless alarm systems compete with wired alarm systems, they dominate the home alarm market and are the top selling systems.
Advantages of a Wireless Alarm
It may not be necessary to use a professional installer for personal security system packages utilizing a wireless alarm. Indeed, the primary advantage of a wireless alarm is its ease of installation as it does not require any special knowledge. A wireless alarm is usually sold as a complete kit including a manual, accessories, detectors, a central unit and batteries.
This is a real advantage compared to a wired alarm where you have to add the price of the equipment to the price of the installation. The second advantage of the wireless alarm is directly linked to the first one. Its ease of installation makes it possible to dispense with a professional installer and thus to reduce significantly the final price.
The wireless alarm works with batteries, so it is not necessary to connect it to the mains. That makes it completely independent and therefore improves the safety of your home even during a prolonged power failure.
Disadvantages of a Wireless Alarm
The main disadvantage of a wireless alarm system is that it is necessary to regularly check the state of the batteries because a loss of energy would render the alarm system out of service. The main advantage of a wireless alarm can therefore turn into its main disadvantage.
As the name suggests, the wired alarm needs wires to communicate and an outlet to operate. This is the system advocated by the professionals because it is the one that presents the best reliability and security. Wired alarm systems account for about half of the home alarm market.
Advantages of a Wired Alarm
In a new house, you get a level of integration similar to an wireless alarm with the advantages of wired communication. A wired alarm works very well for houses under construction because the wires will be completely hidden and there will be no additional cost for the installation of the system.
The wired alarm works very well, for example, for very large houses or multi-storey houses because walls, floors, ceilings are elements that can block or disrupt communication signals. Because of its wired design, it is not subject to anything like piracy and jamming of radio waves since the communication between the control center and the various detectors is done by cables.
In the event of an electrical power outage, a wired alarm system has a back-up battery to take over. That gives it a good level of autonomy while waiting for the restoration of the power, which in the US never takes very long.
Disadvantages of a Wired Alarm
The wired alarm works better for homes with several levels and houses under construction than for houses already built. The installation of a wired alarm usually requires the intervention of a professional installer. That will increase the total cost of the system.
For existing homes, the wireless alarm is more appropriate, as it has a lower cost. For a perfect integration, it will be necessary to embed the wires in the walls, which will further increase the cost. If it is improperly installed, your interior decoration will be affected by the visible presence of wires.
