Below mentioned are the features you should look for when buying a portable motion detector.
Who do you want the alarm to alert when it declares an intruder? Obviously, you’ll be alerted, but some alarms are connected to a spotlight which illuminates the whole area under their range to scare the burglar away.
Also, some people want their portable motion detector to connect to a surveillance Camera – and the Chamberlain CWA2000 provides that option. In this way, you can monitor from your room and not have to go outside and risk yourself.
Portable detector alarms are good, however, you don’t want them to alert you when even a cat enters their zone, do you? Therefore, when choosing them, make sure they offer different sensitivity levels.
There’s nothing technical in choosing your alarm’s sensitivity. All you have to check is their sound level. For instance, the below mentioned Belle Hop Alarm has a sensitivity of 91 dB which is the same as that of a newspaper press.
- Detection Range and Zone
No two portable motion detectors have the same detection range and zone, even in this review. For instance, while the Bitiwend sensor has a range of 26 feet, the Chamberlain CWA2000 has the range of 1,000 feet.
Therefore, when deciding on the detection range and zone, consider the area you want your sensor to cover. For instance, if you want them to cover only indoors, a 30 feet range is more than enough. Conversely, if you want them to protect outdoors, go for the Chamberlain with its 1,000 feet range.
- Power Source
Most people gravitate towards battery powered motion detectors, but those which are connected directly to your home’s electricity grid have their own advantages. For instance, they keep running 24*7 all the time without requiring any intervention. Also, you don’t have to keep a check on their battery to make sure they are working.
That said, if you’re going for wired sensors, you’d be foregoing the portability which comes with their battery-charged counterparts. It is an important feature to let go especially if you’d be using the same sensor at different locations in your home, in which case you might want them to be extremely portable.
