- New security equipment for these systems is less expensive than for wireless systems.
- Can be combined with a wireless system
- Hardwired: A system that uses cables to connect all sensors to a central control panel within your home. The cables are usually installed within the walls or floorboards of your home. The control panel then uses your home’s landline connection to call for assistance (police, fire, medic).
- Wireless: A system which uses wireless technology (wi-fi) to connect all sensors to your home’s central control panel. The panel uses the established network to communicate with the outside for assistance.
- A combination of hardwired and wireless: Custom systems can be configured to have a home totally hardwired and equipped with wireless outside communication (no landline), or have a totally wireless home and hardwired outside communication.
