Average rating:

(based upon one review)

The Qolsys IQ Motion-S sensor is a companion PIR device to your IQ Panel 2 that detects motion within a 35-foot range of unobstructed space. It is easy to install in any room or place where you need to guard against unauthorized entry. It uses our proprietary S-Line Technology to encrypted signals to your IQ Panel 2. It also is backward for legacy 319.5 systems.

You needn’t worry about accidental detection of pets moving through a space. The smart device won’t trigger a response for animals under 40 pounds. Like other products in this line, you can customize the Qolsys IQ Motion-S sensor with automation rules to fit your needs.

For example, you can program it through the IQ Panel 2 to turn on a light if motion is detected in a room. You can also set rules if to increase your energy efficiency and save money on electric bills by turning off lights when there is no activity for a set time. The Qolsys IQ Motion-S sensor puts you in control of managing your home security system.

What Is a PIR?

PIR stands for passive infrared. The Qolsys IQ Motion-S works by sensing changes in the temperature of a room when a person enters a space. Body heat will affect the ambient temperature and trigger the sensor to respond as you have it set. The smart device remembers what the typical conditions of the place.

It works in a passive manner only detecting changes rather than running continuously and going through batteries frequently. That conserves its battery life for optimal operation. It is an effective sensor that runs at an affordable cost for you.

Specifications of the Qolsys IQ Motion-S

The range of the sensor is 35 feet (10.7 meters) by 50 feet (15.2 meters) of open area, so proper placement is essential to protect the maximum amount of space. The maximum horizontal sensing angle is 80 degrees. The sensor will alert you when it detects motion, during pairing, tampering, and even when the battery is getting low.

Installation of the Device

You can install the sensor in a corner of a room or even on a shelf. Places above doors or away from windows are ideal locations for maximum coverage of a room. To begin, you will need to open the device to remove the tabs on the batteries which are included with each sensor. It has three different mounting types to fit any site, flat, corner, or angled. Pick the one that works best.

Then, secure your Qolsys IQ Motion-S in place. You will need to set the sensor to auto-learn so that it can detect the normal conditions in order to determine when a breach has occurred. You can then tamper the device by open and closing the case. The value of the sensor comes from the customization options that you can set next for each smart device in your home.

You can give a unique name for each device you have in your home so that you know exactly where there is an unauthorized entry. You can also set your automation rules for each unit so that it responds appropriately for a given location. Remember, the sensor will learn the conditions when a room is unoccupied so that you can have unique setting for each space.

You can use that information to set it up so that a light turns on when someone enters a room. No more stumbling around in the dark trying to find a light switch. You can also customize the response to turn off light or change the thermostat if no one is detected in a room. You’ll save money on electric bills by making your heating/cooling system run more efficiently.

You can even set it to sound an alarm if the sensor detects activity in a room. The sensitivity of the device ensures that you’ll always know when someone enters a space. No entry will go unnoticed by the Qolsys IQ Motion-S. You can rest assured that your home is protected at all times.

You can change the settings anytime to fit your needs. For example, you can set rules for summer to turn up your thermostat or down during the winter. You can turn lights off or on for a particular room. Simply access the device through the IQ Panel 2 whenever you need to make a change. You can get more value out of your purchase by optimizing it for your situation.

Tips for Proper Operation of the Sensor

You should install the device at least six feet high to give it a good vantage point to scan a room. You shouldn’t put in places that could accidentally trigger a response such as near ceiling fans or HVAC ducts. While they won’t give off infrared light, temperatures changes caused by your HVAC output may cause false alarms and decrease the efficiency of the unit.

For optimal performance, it needs unobstructed space in order to detect temperature changes. The sensor will not go off if your pets (under 40 pounds) enter a room. You won’t get a false alarm if the family dog walks into the 35-foot range of the device. However, you should verify the installation to make sure it responds appropriately as per your automation rules.

While the device will alert you if there is a low power, plan on replacing the two AAA batteries every three years to keep your space secure. The sensor operates best when the casing stays intact. Make sure the unit is completely closed when replacing the batteries. Check the sensor occasionally to make sure it’s working correctly.

The Qolsys IQ Motion-S sensor gives you the peace of mind you need to make sure that your home stays secure whether you’re away or in the next room. You can customize it to fit your needs to get the most out of your home security system. With the Qolsys IQ Motion-S protecting your space, your family is always safe.

Note: Qolsys sensors operate at 319.5 MHz. They will not work with the 345 MHz and the 433 MHz versions of the Qolsys IQ Panel 2 Plus. They are designed for the 319.5 MHz IQ Panel 2 Plus and other 319.5 MHz systems.

Great Motion Sensor

The Qolsys IQ Motion-S is a motion detection sensor for compatible wireless security systems. The sensor operates at a wireless frequency of 319.5 MHz, and it uses Qolsys S-Line rolling code encryption when paired with a Qolsys IQ Panel 2 or compatible Qolsys IQ Panel 2 Plus. The IQ Motion-S has since been discontinued in favor of a slightly upgraded and refined model. However, these updates were fairly minimal, and the IQ Motion-S still works great if you happen to come across one. And if you already have one you are using, then there is virtually no reason to replace it with a newer model. This is a trustworthy and reliable motion sensor that you can count on. We give it a 5 Star rating.

There are many things to like about the IQ Motion-S. For one, it is super easy to program and configure. It supports both corner and flat mounting to give you some different installation options. The sensor offers pet immunity for small animals weighing up to 40 pounds. This is very good if you have a smaller dog or a cat in your household. The wireless range of the Qolsys S-Line Sensors is pretty good, and you should have no communication issues in a typical home. Finally, the S-Line Encryption provides strong security if you are using the sensor with an IQ2 or compatible IQ2+.

The downsides to the IQ Motion-S are fairly minor. As mentioned earlier, the sensor is discontinued, and it can no longer be purchased new. But if you can find a used model somewhere, it should still wrok nicely. Some might consider the coverage area to be small at just 35 feet by 50 feet. However, this is still perfectly adequate for most homes. As a wireless sensor, you will need to replace its batteries periodically. But since the sensor uses just two (2) AAA batteries, it shouldn't be too hard to find some replacements. Use lithium AAA batteries for the best results.

We love the IQ Motion-S, and we think it is a great option for nearly any residential user with a 319.5 MHz system. We give it 5 Stars.

Good: Easy to Program, Corner & Flat Mounting, Pet Immunity, Good Wireless Range, S-Line Encryption

Bad: Discontinued, Somewhat Small Coverage Area, Batteries Must Be Replaced Occasionally

Bottom Line: 5 Stars
