Home Safety Device: Wireless Motion Sensor Alarm
A cost-effective way of safeguarding your home from theft is through a wireless motion sensor alarm. This simple surveillance equipment can detect movement around a designated radius, and set off signals to alert the homeowner. It is a good way of monitoring the safety of your house during the evenings. The sound each unit emits can rouse you from your sleep and give you enough time to take action when a burglar is afoot. You can use this in conjunction with an affordable in-house camera monitor so you get to have a look at the perpetrator before he or she enters your room.
The basic model comes with motion detecting sensors that can sense movement in a set area, and alarm settings with volume controls that can go up to 120 decibels. Other units have infrared features that allow you to indicate the sensor’s scope or coverage. For single, working people without pets who live alone (and are often out of the house), there are models with telephony features that automatically dial a pre-inputted number once it detects unauthorized activity within the area. It alerts the homeowner of the presence of intruders, even when they are out of the city. All they have to do is enter their mobile number. Some units allow up to 3 numbers to be entered. It could be your mobile number, your neighbor’s land line and the local police’s direct line. Once the auto-dialler contacts a designated number, it plays a pre-recorded message of your choosing (e.g., “This is Jane Smith, an intruder has entered my home at 123 ABC Street, DEF Village, GHI City.”).
Depending on the brand, make, and features, prices may vary from fourteen dollars to under four hundred dollars. For instance, a wireless motion sensor alarm with an automatic dialer can cost about thirty dollars.
