As you may have understood by now, I’m an avid fan of all things security. I have tried to cover as much subjects as I can throughout my site so you have one place where you can find all the information you need.
In this section, I’m going to deal with forced entry detection sensors, and you might be surprised to know these are available for more than just doors or windows.
However, let’s start with the more obvious.
Most door and window sensors work by sending a signal back to the control panel when you’ve armed your alarm system. If someone tries to break-in, the contact between door and frame activates and sets the alarm off.
Standalone door and window alarms work much in the same way, only instead of sending a signal to your security system they’ll set off an alarm themselves.
Recessed door and window sensors are becoming ever more popular, and the main reason for that is that no one can see them. They can either be hard wired or if you have a little more money to spend, wireless. I have yet to find a standalone recessed sensor though, as they are designed to work in conjunction with your alarm system.
Window sensors work in exactly the same way as door sensors and are particularly useful if you have windows that are easily accessible (for example ground floor windows). Both window and door sensors are a very useful option if you want to add more security to the perimeter of your home, and if you use recessed type sensors you can do so without it interfering with the décor.
You may be interested to know that most security companies offer these sensors in one of their packages, but if you’re planning on installing one yourself you can check my 6 mini-reviews here.
Indoor/Outdoor Motion Sensors
Motion sensors for indoor use usually work by detecting heat with the help of a technology called PIR or passive infrared. They are designed to react when the temperature rises rapidly, meaning that if someone walks past it their body heat sets the alarm off. This type of motion sensor design also helps reduce the number of false alarms you might get.
Sensors that give 360 degree coverage work in the same way as standard motion sensors. They are installed on a ceiling so the whole room is protected, perfect for places where lots of expensive equipment is housed.
Outdoor motion sensors may cost you extra because they need to be weather proof, and additional technology is used to prevent false alarms. That said they come in a huge range of designs so it’s easy to find one that fits your budget.
Motion sensors are an excellent addition to your security system (especially overnight), and just like door and window sensors they can be added to most service contracts. However if you’re looking for a sensor without the use of a security company, these are my 6 recommendations.
Now, let’s move on with the less obvious.
Glass Break Sensors
Because it’s possible to bypass a window sensor if the window is broken instead of opened, I just had to include some information on this type of sensor. Glass break sensors work differently to a window sensor in that they detect vibration or sound, which means they’re the perfect addition if you want to completely eliminate the chance of undetected window entry.
Of course, they’re available for all types of window so it doesn’t matter if you have tempered, plate, laminated or even wired windows there are sensors on the market that will work for you. Just like all the other sensors I’ve talked about here, you can buy both wired and wireless types.
You can get really simple glass break sensors that can be taped to the corner of a window. If the glass is broken (and your alarm system is on) this triggers a signal which sets the alarm off.
You may think I’m taking security a little too far here, but think about it. At the office there are laptops, safes and filing cabinets with sensitive information in them. In the home you might have a safe hidden in a closet somewhere, an expensive television or all manner of other items that are dear to you. All of these can easily be stolen if a burglar manages to gain entry, and that’s where shock or vibration sensors can help.
There are many different models to choose from and they can either be hard wired into your alarm system or wireless. At the cheaper end of the market, you may need to consider the amount of false alarms you’ll receive due to vibrations that occur around the item you want to protect, so make sure you research this before hitting that “purchase” button.
Garage Door Sensors
Just like any other door in your home, the garage door is a potential security flaw. Many garages have access doors that lead to the inside of your home and this is something to think about when you’re looking at added security.
Garage door sensors come in an array of designs and you can buy what’s called “door contacts” which can be connected to your alarm system so you’re alerted if the garage door is being opened. These will also tell you if the door has been left open by mistake. The more elaborate models use infrared technology and work by sensing movement if the beam is broken.
There is a fair bit of information to take in on this page and some of it might seem a little “overkill”. However, I wanted to make sure you have information on all the possibilities open to you.
Of course, the most common used sensors are door, window and motion sensors, but depending on your home situation and personal needs a garage door or glass break sensor may just be what completes your security system.
