Wireless or hard wired; which security system is best?

A wireless security system is relatively easy to install. Simply put the sensors in place, install the keypad with a backup power supply and connect to a telephone line. Most installations can be accomplished in a relatively short time with minimal fuss or muss.

Wireless systems will work well for a time; years even, but what happens when the batteries die or a sensor goes bad?

Evolving technology guarantees that by the time a sensor fails, there will most likely not be a compatible sensor available to replace it. This means either going without that sensor or installing an entirely new alarm system.

If you go without the sensor, why have the alarm system to begin with?

Replacing the entire system can become costly as you will probably need to change every sensor as well as the keypad. The learning curve for the new system should be factored in as well.

How does a wireless system work?

Each sensor is fitted with a battery. This powers the sensor allowing it to send a signal if the contact is broken by the opening of the door or window. For whatever reason, though, batteries used to power these sensors are not typical AA, AAA, or other readily available battery you can easily obtain. Usually you must return to your alarm company to get a replacement battery for your sensors.

A wired system means just that. Wires connect all sensors to the junction panel eliminating the need for batteries to power them. Installation can take all day for a typical house with an average number of sensors. Drilling through walls, floors, and ceilings may become necessary. The junction panel is much larger and may be hidden in a closet or other hidden space. The junction panel will also need wires from the keypad control and the telephone wires connected as well.

Benefits of a wired system include:

The main panel is hidden making disconnecting harder for thieves. They can still cut the telephone line, but they will have to do it elsewhere. Reputable alarm companies will also recommend how to protect the phone lines outside your home to aid in preventing this.

No batteries to replace, ever, in the system (exception is the backup battery that power the system when there is a loss of electrical power).

The sensors are smaller than wireless because they do not have to contain a battery to power the unit. These lighter sensors are easier to install and do not break as easy.

Typically, it seems these systems may be lower priced than the wireless
