Passive Infrared Motion Detecting Sensors Posts

Last week, we took a look at three of the best alarm panels in the industry. These were the Honeywell Lyric, the Qolsys IQ Panel 2 Plus, and the 2GIG GC3e. Today, we are checking out the sensors that you can add to support these systems. Here is our 2020 Security Sensor Buying Guide!

Sensors are accessories that are added to alarm systems to report specific activity. Each sensor has its own job of looking for a certain type of activity in its designated location. All of the sensors on a system communicate with a single centralized panel or hub. This panel is actively listening for any sensor that is triggered due to a potentially important system event. Adding new sensors is perhaps the best way to expand upon an existing system, and they make awesome gifts and stocking stuffers for the security enthusiast in your life.

Broadly speaking, sensors can be split into two main categories, which are security and life safety/environmental. Security sensors look for activity that suggests potentially unauthorized entry into a monitored and protected location, such as a door being opened, movement in a room where nobody is supposed to be present, or a window being broken. Life safety/environmental sensors look for activity associated with unwanted or potentially harmful conditions that affect the well-being of those in the area, such as a flood, an extreme temperature, a fire, or the presence of CO gas. We'll be taking a look at life safety/environmental sensors another time. Today, our focus is on security sensors.

Wireless Sensor Basics

Before we dive into specific security sensors for our top panel picks, we're going to start by giving you some general, generic information that can be applied to any sensor out there. First, understand that this post is focusing only on wireless sensors. These are almost always the sensors chosen for use with wireless alarm systems. Wired sensors can also technically be used with wireless panels but a converter module is almost always needed. Not to mention the fact that wireless sensors are significantly easier to install, especially for DIY users. The only time you will realistically see wired sensors used with a wireless panel is if a user is upgrading from an older wired system and bringing over their old wired sensors, or in new construction where a user wants to integrate the sensors in with the building. But if you're expanding upon a wireless system by getting new sensors, then the new sensors will almost certainly be wireless.

The important thing to remember when choosing wireless sensors for a wireless alarm panel is making sure the sensor is compatible with the system. It doesn't matter if a sensor has all the specs and features if it doesn't work with your panel! The way to determine compatibility is to look at the lineup that the sensor is from. Petty much every wireless sensor out there is part of a larger grouping of sensors that will all have the same compatibility.

To make it easier for you, we have the three panels we mentioned before (well, make that five, as the Qolsys IQ Panel 2 Plus actually comes in three versions), and all their compatible sensor lineups conveniently listed. We hope that this sheds some light on your options. The only caveat is that for any panel listed here that supports the Honeywell 5800 Sensors, we must be clear that this is only for the uni-directional sensors with one-way communication in the lineup. Any bi-directional Honeywell 5800 Sensors with two-way communication will not work with any of the aforementioned systems. The bi-directional Honeywell 5800 Sensors are only compatible with the Honeywell LYNX Touch and VISTA Systems, which were not included in our buying guides.

With that out of the way, here are compatible sensor lineups by system:

• Honeywell Lyric - Honeywell SiX Series, Honeywell 5800 Series, 2GIG 345 MHz Series
• 2GIG GC3e - 2GIG eSeries Encrypted Sensors, 2GIG 345 MHz Series, Honeywell 5800 Series
• Qolsys IQ Panel 2 Plus 319.5 MHz - DSC PowerG Sensors, Qolsys S-Line Sensors, Qolsys Legacy 319.5 MHz Sensors, Legacy Interlogix Sensors, Legacy GE Sensors
• Qolsys IQ Panel 2 Plus 345 MHz - DSC PowerG Sensors, Honeywell 5800 Sensors, 2GIG 345 MHz Sensors
• Qolsys IQ Panel 2 Plus 433 MHz - DSC PowerG Sensors, Legacy DSC 433 MHZ Sensors

You will notice that some of the sensor groups listed above are italicized and underlined. That is done to identify the lineups of encrypted sensors. These encrypted sensors have special protection measures put in place to make them more secure and less prone to being hacked or defeated by malicious attacks. Encrypted sensors tend to have more restricted compatibility. They may follow a special enrollment process. Encrypted sensors often use bi-directional communication so that the sensor knows that it is actively paired with the system. Many encrypted sensors may only be paired with a single system at any given time, and the sensor will need to be deleted from its existing system before it will work with a new one.

It's okay to use non-encrypted sensors with your system, especially in zones that are less likely to trigger an alarm, like a second story window. Many users will opt to use a mixture of both encrypted and non-encrypted sensors. Other users feel comfortable using entirely non-encrypted sensors. It really comes down to your level of comfort. Non-encrypted sensors are secure in most situations, and they are still tricky to defeat. But going fully encrypted is recommended for anyone seeking maximum security. One tip if you do decide to go with some non-encrypted sensors is to avoid letting others know what wireless frequency your sensors use or what type of system you have installed. Knowing the frequency and the system being used makes it much easier for a savvy intruder to defeat a sensor.

Door & Window Alarm Sensors

Now that you know some basics that apply to almost all wireless sensors, let's start talking about specific types and models. Door and window sensors will let a system know when a door or window has been opened or closed. These are some of the most basic and easy to use sensors on a security system. These devices work by using a larger sensor portion and a smaller magnet portion. The sensor is placed on or inside the door or window frame, and the magnet is placed on or inside the moving portion of the door or window. When the door or window is opened, the magnet will move away from the sensor. This will trip a metal reed switch inside the sensor, which will tell the sensor to alert the system to the opened door or window. All of the sensors we've listed here follow that same method of operation.

Door and window sensors can be split into two (2) main categories. Surface-mount door and window sensors are mounted outside the door or window and its accompanying frame on the surface. The advantage to surface-mount door and window sensors is that they are very easy to install, and they can usually be mounted using double sided foam tape. But some users may not like how they are visible on the outside of the door or window. If you don't like the appearance of visible surface-mount door and window sensors, then you might instead consider recessed door and window sensors. A recessed door or window sensor is installed inside a door or window and its frame, so that it is hidden and cannot be seen from the outside. Recessed door and window sensors are more difficult and time-consuming to install, because you must drill holes in both the door or window and its accompanying frame. Whether you decide to use surface-mount door and window sensors, or recessed door and window sensors is up to you. Most DIY users and Alarm Grid customers in general will use surface-mount door and window sensors.

Now let's look at some door and window sensors.:

Motion Sensors

Motion sensors use passive infrared (PIR) technology to detect movement within the sensor's coverage area. This is done by looking for the changes in infrared (IR) energy that occur when a person, animal, or object comes within the sensor's field of view. Standard motion sensors are typically PIR only. These are appropriately called PIR motion sensors.

Some motion sensors will also use microwave technology in addition to PIR technology. This involves having the sensor send out microwave signals and seeing how the signals bounce off of objects in the area. Movement will change the pattern of these microwave signals, and the sensor will be able to detect this. These motion sensors that use both microwave and PIR are called Dual-Tech motion sensors. The purpose of using both PIR and microwave together is to prevent false alarms. A Dual-Tech motion sensor will only activate and alert the system if both its PIR sensor and its microwave sensor are triggered. A microwave sensor is not vulnerable to the same environmental issues that may cause a false activation on a PIR. You will not find a motion sensor that uses microwave technology without PIR detection, as microwave alone would result in too many false alarms without having PIR to confirm movement.

One feature that you will often see listed on a motion sensor is pet-immunity. A motion sensor that has been set up for pet immunity can be configured to not "look" in the areas close to the ground where pets and small animals walk. Instead, the motion sensor only looks in the areas higher up, where humans move while walking upright. A pet immune motion sensor is not impervious to small animals, and you must position it carefully so that it works as intended. Pet immune motion sensors normally have a weight limit, where animals under that weight limit should avoid triggering the sensor, assuming that the sensor is installed properly. Please note that most pet friendly motion sensors will require you to set the sensitivity for the sensor to the lowest possible setting.

When it comes to motion sensors, mounting them carefully is very important. A motion sensor may cause false alarms on the system if it is not installed properly. These sensors should not be facing any vents, air ducts, ceiling fans, or curtains that may cause the sensor to activate without any movement. If you are using the motion sensor for pet immunity, then it should also not be facing any furniture or stairwells that your pet could use to get within the sensor's field of view. You will likely want to perform a Walk Test of your motion sensor to make sure that it responds properly when movement is present, and does not respond due to other external factors when there is no movement. You should also have any pets participate in the Walk Test to ensure that pet immunity is working properly.

We recommend reading the following FAQs to learn more about motion sensors:

Glass Break Sensors

The last type of security sensors we will be discussing are glass break sensors. These sensors include built-in microphones, and they actively listen for the unique sound of glass breaking. Most of these sensors will need to hear both the high-pitched shattering sound of the glass breaking, as well as the low-pitched sound of an object striking against the glass in order to activate. This design choice is to prevent false alarms caused by similar sounds. Most users will use glass break sensors to monitor windows, but they have also been known to work effectively on protective glass display cases that store valuables, such as what you might find in jewelry stores or gun shops. Most types of glass will work with glass break sensors, though there are some exceptions. For example double and triple pane glass windows won't work reliably. The same is true for coated or "safety" glass. Refer to the manual for the exact glass break detector you are using to determine compatibility.

A single glass break detector can monitor multiple windows or display cases, as long as the glass it is monitoring is within its detection range, which is typically 15 to 25 feet. Any glass that is being monitored must have a direct line of sight with the sensor, with no obstacles blocking the path that sound will travel through. When testing your glass break sensors, it is strongly recommended that you us a glass break simulator. These devices will mimic the sound of the glass breaking and activate your glass break sensors without actually breaking any glass. Remember to refer the instructions of your glass break simulator for more information. When choosing a glass break simulator, it is best to use a simulator from the same manufacturer, if possible. We have a Honeywell Glass Break Simulator and a DSC Glass Break Simulator available on our website. If you get one of the 2GIG Glass Break Sensors mentioned in this buying guide, then the Honeywell Glass Break Simulator is best for testing. Otherwise, just match the manufacturer.

Door & Window Alarm Sensors

Now that you know some basics that apply to almost all wireless sensors, let's start talking about specific types and models. Door and window sensors will let a system know when a door or window has been opened or closed. These are some of the most basic and easy to use sensors on a security system. These devices work by using a larger sensor portion and a smaller magnet portion. The sensor is placed on or inside the door or window frame, and the magnet is placed on or inside the moving portion of the door or window. When the door or window is opened, the magnet will move away from the sensor. This will trip a metal reed switch inside the sensor, which will tell the sensor to alert the system to the opened door or window. All of the sensors we've listed here follow that same method of operation.

Door and window sensors can be split into two (2) main categories. Surface-mount door and window sensors are mounted outside the door or window and its accompanying frame on the surface.

Whether you decide to use surface-mount door and window sensors, or recessed door and window sensors is up to you.

You will likely want to perform a Walk Test of your motion sensor to make sure that it responds properly when movement is present, and does not respond due to other external factors when there is no movement. You should also have any pets participate in the Walk Test to ensure that pet immunity is working properly.

Glass Break Sensors

The last type of security sensors we will be discussing are glass break sensors. These sensors include built-in microphones, and they actively listen for the unique sound of glass breaking. Most of these sensors will need to hear both the high-pitched shattering sound of the glass breaking, as well as the low-pitched sound of an object striking against the glass in order to activate. This design choice is to prevent false alarms caused by similar sounds. Most users will use glass break sensors to monitor windows, but they have also been known to work effectively on protective glass display cases that store valuables, such as what you might find in jewelry stores or gun shops. Most types of glass will work with glass break sensors, though there are some exceptions. For example double and triple pane glass windows won't work reliably. The same is true for coated or "safety" glass. Refer to the manual for the exact glass break detector you are using to determine compatibility.

A single glass break detector can monitor multiple windows or display cases, as long as the glass it is monitoring is within its detection range, which is typically 15 to 25 feet. Any glass that is being monitored must have a direct line of sight with the sensor, with no obstacles blocking the path that sound will travel through. When testing your glass break sensors, it is strongly recommended that you us a glass break simulator. These devices will mimic the sound of the glass breaking and activate your glass break sensors without actually breaking any glass. Remember to refer the instructions of your glass break simulator for more information. When choosing a glass break simulator, it is best to use a simulator from the same manufacturer, if possible. We have a Honeywell Glass Break Simulator and a DSC Glass Break Simulator available on our website. If you get one of the 2GIG Glass Break Sensors mentioned in this buying guide, then the Honeywell Glass Break Simulator is best for testing. Otherwise, just match the manufacturer.

Hi DIYers! Some of the most important sensors used with alarm systems are passive infrared (PIR) motion detectors. When installed properly, these devices do an excellent job of detecting any motion that can occur inside a home or business. They are critical for a complete security setup.

But while motion sensors provide many great benefits for alarm systems, they are also some of the most prone to experiencing problems and issues. These problems are usually the result of PIR motion sensors being mounted poorly and/or in unsuitable locations. Problems may also occur if a motion sensor is ever used in an improper application or setting for its intended use.

By obtaining a better understanding of motion sensors and how they operate, a user is less likely to experience reoccurring problems with their PIR motion sensor. Just a few tips and general guidelines need to be followed. It all comes down to installing the motion sensor correctly, selecting a good location for the device and choosing the correct type of PIR sensor. If these three tips are followed, then a motion sensor will be much more likely to work properly.

First, it's a good idea to understand what a motion detector is trying to accomplish and how it works. The goal of a good motion sensor is to detect the motion of a human intruder, while also ignoring unimportant sources of motion, like a ceiling fan, curtains or a pet. But this is easier said than done. If a motion is too sensitive, then false alarms will occur. But if it isn't sensitive enough, then it won't detect intruders.

A PIR motion sensor works by taking a reading of the infrared (IR) energy in a room and detecting any significant changes in IR energy that occur. All people, animals and objects give off some amount of IR energy. When a person, animal or object comes into the field of view of the motion sensor, it causes a change in detected IR energy. Once the motion sensor has detected enough of a change, it will send an alert to the alarm system to let it know that motion is present. The alarm system will then respond accordingly based on the programming settings.

But most users wouldn't want a motion sensor to activate because of very tiny changes in IR energy. This would cause too many false alarms on the system. That is why motion sensors usually have sensitivity levels that can be adjusted through an adjustable pulse count. The pulse count determines how large of an area needs to experience a change in IR energy before the motion will activate. A higher pulse count will mean that a wider change in IR energy is needed to activate the motion detector, thereby making the sensor less sensitive. Likewise, a lower pulse count will increase the sensitivity. Many motion sensors also have lenses that can be swapped out to provide the optimal view for the device.

But it's important to remember that a PIR motion sensor will only work if it can "see" the movement. That is why it is critical that a motion sensor is mounted at a height where it can properly detect a human intruder. A hypothetical scenario is to imagine a motion sensor that is mounted too high up. In that case, a person could just duck down and move below the field of view without setting off the motion sensor.

Most motion sensors are mounted at a height of about 6 to 8 feet high. This should allow the device to detect any human moving in the room. For optimal coverage, we generally recommend mounting motion sensors in the corner of a room. But mounting height becomes even more important for "pet-friendly" motion sensors. The goal of a pet-immune motion sensor is to detect the motion of a human walking upright, while still ignoring the motion of a small animal walking close to the ground.

Users should realize that pets can still set-off pet immune motion sensors, even if the pet is within the suggested weight limit. But the goal is to prevent this from happening. By setting up the motion sensor correctly and by making it impossible for the pet to get within the field of view (FOV) of the motion sensor, false alarms are much less likely to occur because of the activities of pets.

If a user intends on using a PIR motion sensor in a home with pets, they should first make sure their PIR motion detector offers pet-immunity. A pet-immune motion sensor features a lens that is designed to detect the motion of a human walking upright, while ignoring the movement of pets closer to the ground. If a motion does not have this special type of lens, then it will still see a pet moving throughout the room.

Second, a user should make sure that their pet is within the listed weight limit of the motion sensor. The idea here is that pets that weigh more are usually larger in size. So if a dog is 60 pounds, it is estimated that it will be large enough to set off a pet-friendly motion sensor for pets rated for up to 40 pounds. Of course, the pet-immunity values provided from motion sensor manufacturers are rough estimates. But these values should still be taken into account when planning.

Third, the motion sensor should be mounted at a proper height. It will need to be at a height where it can still detect the movement of a human, while ignoring the movement of a pet closer to the ground. Generally speaking, 7.5 feet high is a good height for accomplishing this. But this height can vary for different sensors. Also, the motion sensor should be mounted at a proper angle. If it is facing at too low of an angle, a pet might still set it off.

Finally, the motion sensor should not be facing any "obstacles" that a pet could climb on top of to get within the FOV of the sensor. Even if the motion sensor is mounted at a good height and at a proper angle, a pet can still manage to set it off if it is able to get up high enough. For example, a pet could climb on top of a sofa or walk up the stairs and get within the motion's FOV. For that reason, motion sensors shouldn't be mounted facing furniture or a stairway if pets are present.

There are also a few general guidelines that a person should follow when choosing a location for a PIR Motion. Remember, these devices respond based on changes in infrared energy. By installing a PIR motion near a vent or an air duct, the flow of hot or cold air could result in false alarms. A similar principle can be applied for appliances such as stoves and refrigerators. It is also advised that users do not install motions facing windows, as heavy sunlight could cause the device to activate. Additionally, motion sensors tend to work poorly in environments such as bathrooms, garages and attics, since they tend to feature high levels of humidity and/or dust. A user should also avoid mounting a motion sensor facing a moving ceiling fan or curtains, as this may result in false alarms.

Some users may also overlook the type of PIR motion sensor that is being used. Not all motion sensors are created equal, and there are many types of possible applications. For one, there are residential versus commercial motion sensors. Residential motion sensors are typically less sensitive and better-suited for homes and apartments. Pet-immunity features are usually only found on residential motion sensors. On the other hand, commercial motion sensors are usually more sensitive and feature lower pulse counts. A commercial motion sensor will also typically feature a larger FOV, making it more suitable for commercial settings.

Another common issue is to use an indoor motion sensor in an outdoor setting. Outdoor rated devices feature rugged exterior casings that protect the devices from exposure to rain, wind, dust and extreme temperatures. If a user tries to use an indoor motion sensor in an outdoor setting, then it is very likely that the device will become damaged due to environmental exposure. And while a user can use an outdoor motion sensor indoors, this is usually not recommended because outdoor motions are considerably more expensive. Make sure that the motion you use is suitable for the desired environment.

Following these tips will help ensure that your PIR motion sensor works properly and doesn't cause you problems. When used properly, these are great devices that do an excellent job of keeping homes and businesses secure. You can buy motion sensors of all types on the Alarm Grid website!
