Wireless alarm systems are the simplest to install and the most popular choice for homes that are already built. They are the perfect solution for installing a security system into an existing home where running wires is impractical. A wireless kit requires no wiring except for the connection between the control panel to the transformer which plugs into a standard wall plug. On average, you can secure your entire home in 1-3 hours …even if you’ve never installed anything before.
The high-end Honeywell/Ademco wireless equipment is extremely dependable but you must be prepared to spend a little money for all of the wireless sensors.

Hardwired alarm systems are ideal for installation in “new construction” and homes with easily accessible attics and basements. In new construction, because the walls and ceilings are still exposed, wiring is easily accomplished without having to “fish” wires through finished surfaces. In homes with accessible attics or basements, wiring to the various protection points will typically require “fishing” the wires into the wall cavity where the sensor will be attached.
In general, hardwired systems are less expensive than wireless systems, do not require batteries for sensors and allow for locating the control panel remote from keypads. This adds a layer of security because the control panel cannot be disabled by knocking a keypad off the wall.

The current trend in home security is to install a hybrid system. These systems incorporate both hardwired and wireless features. The control panel is hardwired to the keypad which contains a wireless receiver that will accept wireless signals from the wireless sensors. A hybrid system allows you to use both hardwired and wireless sensors.
In the areas that you can easily hardwired a sensor to the control panel, you will save money on the sensor. In areas that cannot easily be wired, you have the convenience of using a wireless sensor.
Existing hardwired systems can be made hybrid by simply wiring a stand-alone wireless receiver to the control panel
