A wireless motion detector is an integral part of the motion alarm system which you may have installed in your home which can help to protect your property from any potential intruders. You can also purchase a wireless motion detector separately and install it in any room you want to protect as part of a home improvement plan. They are available at quite a low cost these days, but they can be a very useful security addition to any home.

These products operate by sending out an infrared beam (Passive Infrared Sensor) and when motion is detected they will trigger the alarm in to action. The range of operation of the unit will vary depending on which product you have but commonly they are effective to around a maximum of 40 feet. If you wish to install a motion sensor independently from an existing home alarm system then you can do that very easily as they can be mounted on any wall or on flat surfaces and most of them will simply run off batteries. Following this we have reviewed two of the best models that you may wish to consider when you are planning to shop for your installation.

Honeywell RCA902N1004/N Wireless Motion Detector

This motion detector is an add-on for the Honeywell RCWL300A, RCWL330A, RCWL330A and all the Honeywell Decor series chimes. It runs on a 9 volt battery and will also require the RPWL305A converter for use with the door chimes. You can use this unit to detect motion in any room or alternatively to detect people who are approaching your property. This Honeywell product is designed to work both indoors or out. You can find the Honeywell RCA902N1004/N online with free shipping for less than $40.

Remote Control PIR Wireless Motion Detector

Whilst the Honeywell product mentioned above is an add-on unit for an existing door chime this system is a stand alone device which can be purchased in two packages containing either one or three detectors. It comes complete with a key ring based remote control for wireless activation and deactivation. Once mounted on the wall the sensor head can be adjusted to point exactly to the area you wish to protect. The range of operation is 110 degrees of coverage and the product will sense motion from up to 30 feet away.

The device is armed with the remote which can send a signal from up to 25 feet away. You can then select between either a chime which can be used to simply to alert you if somebody enters your property, or the powerful 120dB alarm which can help to deter any thieves who may enter to try and steal your possessions. You can program a delay of 45 seconds allowing you to leave the property and an entrance delay of up to 15 seconds before the device is activated if it senses any movement.

As well as the PIR sensor this device comes complete with a set of magnetic sensors which can be placed on a door or window and enable the alarm to be triggered if the magnetic connection is broken. So you can enjoy two levels of protection at the same time. The Remote Control PIR Wireless Motion Detector is powered by 3 AA batteries and retails for less than $30 for the single unit and less then $90 for three units. You can also purchase extra remote control units for this item which is very useful for all the members of your family and the customer reviews of this alarm have been generally very favorable. It is a very good value for money item and if you buy it from Amazon you can enjoy free shipping!

If you need to place a wireless motion detector outdoors you may wish to opt for the first product from Honeywell as is fully operational indoors or out, but for indoor use the second item is really great as it comes complete and ready to protect your house. You could for example place one device by your back door and put the magnetic sensor on the window so that the area is fully protected and the alarm will be activated if it detects any movement in that area or by the window being smashed. The chime function on the second device would also be suitable to alert you to the entrance of a customer in to a small shop or business.
