Delicious - Hardwired vs. Wireless Security Alarm Systems - How Secure is your Security System
Age old questions abound which spark a constant series of debates. Which is better, Chevy or Ford, Coors or Budweiser, winter or summer?
Ask a couple of alarm guys which is better, hardwired or wireless and you are sure to receive some pretty strong opinions supporting one or the other. Battle Lines being drawn, let’s try and get to the bottom of this shar

Hardwired alarm panels are less expensive than wireless panels, but they are harder to install. Keep this in mind if you are planning on doing the installation yourself. An average home installation with a hard-wired system takes about 12-16 hours. A typical wireless installation will take less than 4 hours.

The main difference between a hardwired and a wireless alarm panel is how each one communicates with the protection devices connected to the system. A hardwired panel will require a wire to each “zone” or device on the system, while a wireless system utilizes a radio frequency to communicate with the “zones” or devices that are

e, even the most sophisticated wireless alarm panels are useless if the transmitter batteries are dead, therefore supervised wireless panels are programmed to check in with each of the remote transmitters at least once every 24 hours. If your transmitter has a low battery, the keypad/arming station will immediately inform you of the trouble condition.
