Buying Guide for Motion Sensors

Motion Sensor Buying Guide


If you would like to take steps to safeguard your home or business from intruders, then you are likely wondering what approach you should take so that you can have peace of mind. Although you can try many methods, installing motion sensors is one of the best ways to protect the things that matter the most. It won't take long, however, for you to discover that several types of motion sensors are for sale, and choosing the right one can be a difficult challenge to overcome.
Taking the wrong path will force you to get stuck with a product that does not make sense for you, which is a waste of time and money. Rushing into the buying process without giving it much thought is a mistake that you need to avoid, but getting the right type of motion sensor for your property and needs will be easy once you learn about the things for which you should look.

Wired Systems


Motion detectors that connect to a security system with wires are a popular choice when it comes to home protection. They will provide a stable connection and have a constant supply of power, so you know that they will always be active when you need them. Unless you are trained, you won't be able to install a wired system without the help of a professional.
Also, a team of experts will usually monitor a wired system and call the police if they notice something that is out of place. You will need to pay for that service, however. Even though it will offer a high level of protection, a wired system is more costly to install than the alternatives, so you will need to take your budget into consideration before moving forward. If the price does not concern you, then this option will work wonders to put your fears to rest.

Wireless Systems


Because they are cheap and easy to install, some residents and business owners prefer wireless motion detectors. Once you put them in position, they will monitor the area for movement and notify the control panel when anything happens. If your device is armed, the alarm will sound, giving you enough time to react. A high-end motion detector can connect to an app on your smartphone and send notifications when something triggers it.
You can also find cheap models that don't include advanced features, but you will need to decide what balance is right for you. The biggest downside to this path is that you will need to replace the batteries on a regular basis. People sometimes forget to do so, and their motion detectors are rendered useless as a result. Because wireless sensors depend on Wi-Fi to operate correctly, a criminal could use a Wi-Fi jammer to disable your entire security system.

Infrared


Motion detectors use different types of sensors to detect movement, and you must take this factor into account before you make a purchase. The first type at which we are going to look uses infrared technology to protect your home or office. When you activate your security system, the infrared monitor will read the temperature of the room to establish a baseline. If it detects changes in the temperature that are consistent with the amount of heat that humans produce, it will activate the alarm.
This option is a smart move when you plan to use the sensors outside, and they will work well no matter how much light is present. Infrared sensors are not easy to defeat, and having them installed is one of the best ways to ensure that your personal belongings don't fall into the wrong hands. Depending on your area, you might even enjoy insurance discounts for installing an infrared system because it reduces the odds of a theft taking place.

Radar


If your goal is to prevent intruders from gaining access to a building, radar sensors are another option that can get the job done right. They operate by sending radio waves into the room and monitoring the way that they bounce back to the sensor. If people enter the area, they will change the way that the radio waves are reflected, and this will set off the alarm.
Consumers who use this type of sensor are often pleased with the results, and you will probably feel the same way if you follow in their footsteps. But it's important you realize that not all radar sensors are equal. Cheap models will still let you know when something moves, but they can be set off by animals or cars in the distance. A quality radar sensor can tell the difference between people and most animals, so you don't need to worry about false alarms.

Photodetector


With a photodetector, you will place a laser on one side of the room and a sensor on the other side. The laser will provide a consistent beam, and anything that crosses it will break it, causing the alarm to activate. You can even opt for models that use a type of light that is invisible to the human eye, allowing you to install the system outdoors without stress. These sensors are useful in most cases, but they are not without limits.
If someone knows the location in which you have placed your photodetector, they can take steps to avoid detection. A criminal could also use a laser to blind your photodetector and to move freely without problems. You are not likely to encounter someone who is willing to go through that much trouble to gain access to your property, but it's still a risk about which you should think if you want to see the whole picture.

Final Thoughts


When it comes to the safety of your property and family, you don't want to take chances. With the right plan and a little dedication, you can find the perfect motion sensor with ease, and you will have confidence in your decision. Some consumers have opted to install more than one type of sensor to make their security system all but impossible to defeat, and doing so is a wise move if it won't break your budget.
