Hardwired or Wireless

Security alarms systems can be installed with a physical wire, other wise known as hardwired, or it can be installed wirelessly with each device being powers by batteries. Hardwired alarm systems are more reliable and require less maintenance. Hardwired alarm systems are more labor intensive and sometimes not possible at all due to other factors. Wireless alarm systems are very flexible and use less labor to install. Wireless alarm systems do take more to maintain reliability and have a high upfront cost.

Components

Security alarms systems use different sensors to detect different activities. Motion sensors detect the movement in an area using infrared light. Door and window sensors use a magnet and contact to detect when a door or window changes state from open to close. A beam detector works like a motion detector by emitting a beam of infrared light over long distances and detects when the beam is crossed. These components can be used on either a hardwired alarm system or a wireless alarm system.

Integration
