Your security system’s network of sensors, connectivity and control panel determines whether or not it is wired. Wired systems connect sensors through wires to the control panel and then communicate externally with a landline connection. A wireless security alarm system’s sensors communicate with the control panel through Radio Frequency (RF) technology and then externally with a cellular link, as though your system is a cellphone itself. Additionally, a security system can be a hybrid. The two main communication types in a security system are from sensors to the control panel and the control panel to the external world.
If you don’t have an active landline, you may opt for a completely wireless security alarm system. However, if you have an active landline connection, you can choose landline as the primary and cellular as the secondary external connection. A wired security system may seem reliable due to connectivity issues during power outages. However, a wireless security alarm system has many advantages. It can be used in many places, even hard to reach locations where wiring is damaged or difficult. Wireless systems are easier to install if you rent a house or do not want to drill holes in your walls and pay for the renovation. They also give a cleaner look to your home. It is easier to dismantle and reinstall wireless alarms at your new place if you move around a lot.
A wireless security alarm system costs more than a wired alarm system but has a lower installation cost and time. Wired systems take longer to install as they require drilling and hiding the wiring. They also have additional accessory costs such as clips and cables. The backup batteries of both systems will need to be changed by you or a professional after approximately five years. Wireless alarm devices have batteries that may need to be changed every two years, though this is not the case with wired alarm systems as their devices are powered through wires. Due to being operated through batteries, wireless alarm systems are easier to expand on if any additions or extensions are made to the system. A wired system will require a new cable from the control panel, and is a messy and complicated procedure. Unless you have a vast property where coverage may be an issue, a wireless security alarm system or a hybrid will suit most of your needs.
