Looking to buy Motion Sensors?

One of the most effective ways of keeping your home safe is by installing a motion detector inside. Once it’s properly set up, a motion detector can keep an invisible eye out for you while you’re asleep and when you’re away from home. Easy to activate or deactivate by entering a code in their keypad, they’re the set and forget solution for home security!

As well as providing protection from break-ins, motion detectors can be useful in a range of other situations. For instance you can set up a motion detector to alert you if a pet or young child has found their way into an area of the house that’s out of bounds, like the basement or the shed.

Are all motion sensors the same?

Although all motion sensors perform the same job, they aren’t all the same, and understanding the difference between them will help you make the right choice for your home. The most common type of motion sensors are called PIR sensors. PIR stands for Passive InfraRed, which means that PIR sensors use infrared radiation that’s naturally generated from heat sources to detect movement. PIR sensors are cheap and effective motion sensors, but they aren’t the most effective type of sensor available, and you need to consider heat sources when you set them up.

Another common type of motion sensor are microwave sensors. These motion sensors emit pulses of weak microwaves and measure the reflection of moving objects. It’s the same concept that radars and sonars use, just on a smaller scale. Microwave sensors cover a larger area than PIR sensors and are more precise, but they’re more expensive and can be too sensitive - placing a microwave sensor towards a window can cause the sensor to pick up leaves falling from trees outside. It’s quite common for manufacturers to combine microwave sensors and PIR sensors into a single motion sensor for additional security.

Where should I place motion sensors?

Most of the motion sensors you’ll find in this category are completely wireless, meaning that they’re easy to set up yourself. There are a couple of things to bear in mind when you’re installing them to maximise their effectiveness.

First you should think about the places in your home that make for attractive entry points for a burglar. These include your front and rear doors, patio doors, garage doors and windows that face onto side streets. You should also consider placing your new motion detectors along major hallways in your home, as a burglar is likely to use them to move from room to room in your home. If you’re installing PIR sensors, make sure to avoid placing them in range of a radiator, heating pipes or anything else that heats up, as this will cause false alarms.
