12 best safety technology motion sensors

Safety technology motion sensors, often referred to as motion detectors, are electronic devices designed to detect movement within a specified area. These sensors are widely used in various applications, including security surveillance systems, home automation, and industrial settings. They play a crucial role in enhancing safety and security by triggering alarms, lights, or other actions in response to detected motion. Here's what you need to know about safety technology motion sensors:

  1. Types of Motion Sensors:

    • Passive Infrared (PIR) Sensors: PIR sensors detect changes in infrared radiation emitted by warm objects in their field of view. They are commonly used in security systems, turning on lights or alarms when motion is detected.
    • Ultrasonic Sensors: Ultrasonic sensors emit high-frequency sound waves and detect changes in the reflection of these waves caused by moving objects. They are used in applications like occupancy detection and burglar alarms.
    • Microwave Sensors: Microwave motion sensors emit microwave signals and measure the reflection off objects.They are sensitive and suitable for large areas and outdoor use.
    • Dual Technology Sensors: These sensors combine two technologies (e.g., PIR and microwave) for increased accuracy and reduced false alarms.
    • Vibration Sensors: Vibration sensors detect motion or tampering by measuring vibrations in surfaces. They are often used in anti-tamper systems.
    • Image Sensors: Image sensors, such as cameras, can detect motion by analyzing changes in video frames. They are used in security cameras and video surveillance systems.
  2. Applications:

    • Home Security: Motion sensors are commonly integrated into home security systems to detect intruders and trigger alarms.
    • Lighting Control: Motion-activated lights are energy-efficient and enhance safety by automatically illuminating pathways and areas when motion is detected.
    • Occupancy Sensing: In commercial buildings, motion sensors are used to control lighting, heating, ventilation, and air conditioning (HVAC) systems based on occupancy.
    • Industrial Automation: Motion detectors are employed in manufacturing and industrial settings for tasks such as equipment monitoring, quality control, and robotics.
    • Video Surveillance: Motion-activated recording in surveillance cameras helps conserve storage space and focuses on relevant events.
    • Smart Home Automation: Motion sensors are integrated into smart home systems to automate various functions, such as turning on lights or adjusting thermostats.
  3. False Alarms: To reduce false alarms, modern motion sensors incorporate advanced algorithms and adjustable sensitivity settings. Careful placement and calibration are essential to minimize false positives.

  4. Power Sources: Motion sensors can be wired or wireless. Wired sensors are connected to a power source and a control panel, while wireless sensors use batteries or solar power for energy.

  5. Integration: Many modern motion sensors can be integrated with other smart devices and security systems, allowing for remote monitoring and control via smartphones or computers.

  6. Privacy Considerations: In areas where motion sensors are installed, privacy concerns may arise. It's important to use motion sensors responsibly and ensure compliance with applicable privacy laws and regulations.

In summary, safety technology motion sensors are versatile devices used to detect motion in various applications, from security and lighting control to industrial automation and smart homes. They enhance safety and security by triggering appropriate responses when movement is detected within their designated areas of coverage.

User questions & answers

Question: Will this work with an Arlo camera
Answer: This product does not have a hinge or a lock. I used two hard plastic cable clamps on the left side of the cage, to mimic a hinge.

User questions & answers

Question: Does the Driveway Monitor have to be in line of site with the receiver
Answer: For reliable detection w/o high sensitivity mode and false alarms, in my application the vehicle needs to be within about 4 feet. And by the way, I found the solar powered model's nicad batteries die after the first winter - buy the regular battery powered one (which only lasts a few years more before crapping out)!
Question: Where are the batteries located
Answer: No, it is not directional.
Question: How close must a vehicle be to the monitor to be detected
Answer: Not really. The slots are not big enough to fit your fingers through to push a doorbell. It's made to screw mount to the wall so you would have to modify it or remove the screws to change the battery.
Question: Is the sensor directional
Answer: STI manufactures wire cages specific for cameras, the best way to determine the correct cage would be with your dimensions H x W x D, visit this link to view our options https://www.sti-usa.com/series/cctv-guard/.

User questions & answers

Question: Is it possible to add additional remote sensors. Are they battery powered. How far away can they be placed
Answer: you can have may of these units, however, they are not able to communicate with each other they will all just work as individual units. You may have some interference if the beams cross.
Question: Does anyone think Rex would work in a barn directed outside to deter a cougar? It would be directed towards the woods beyond the barn. Thanks
Answer: Here is a SWAG (scientific wild ass guess) - it might work. Our Rex is pointed out our front door and if I run up to the door (not what I think a cougar would do) it doesn't bark until I'm right by the door (which seems a bit late to me). If I tarry in the driveway, about 15 feet from the door and talk with someone (like a stealthy cougar slowly approaching?) Rex eventually catches on and starts barking. My theory is that the further away the cougar is when the barking starts, the better the cougar is deterred. And my theory is the cougar would approach slowly. Ideally your cougar friend would have a fear of dogs. Now if the cougar considers dogs yummy, then Rex could be an attractant!
Question: What is the perimeter range of the unit? If someone approaches from the back of where the unit is located will it still detect
Answer: 6-2-13 -- My unit is aimed from a bedroom through a stucco house wall to the carport where people approach my front gate. At full sensitivity my Rex II picks up activity at about ten feet ahead and four feet from the back. I only turn it on when I go out or if I anticipate solicitors, in which case I close the door to the room so the cats won't be scared, although they have become used to it.
Question: Will something as small as a cat walking by trigger the alarm
Answer: Yes. Anything in front will trigger the alarm.

User questions & answers

Question: I can't really see the back of the case. Is this sensor easily mounted in the 90-degree corner of a room, or must it be mounted on a flat surface
Answer: I purchased two(2) of these in March of this year and tried pairing them with my Smartthings v2.0 Hub. They were both recognized as a Z-Wave Door/Window Sensors. I contacted support and Alex responded very quickly by changing it to a Z-Wave Motion Sensor and running the fix utility. Though the change was reflected on my mobile phone, it seemed to list both sensors as continuously detecting "Motion". Alex gave me some documentation to read while researching the issue. In the mean time it still wasn't working so I ended up excluding it and reincluding it several times. My first thought was that this device did NOT work with Smartthings v2.0 Hub, However, in frustration, I hid them underneath something and waited a longer time. What I found was that it reports motion for a MUCH longer period than the SmartSense Motion Sensor. With the SmartSense Motion Sensor I can sit still for a couple seconds and it will reset to "No Motion", with the Ecolink it stays active (i.e. detecting motion) for a much longer time (~4 minutes). Hope this helps.
Question: Does this device re-broadcast the received z-wave signal? I've recently learned not all devices do this
Answer: 01/27/2015 - Yes! My Wink hub is now on software version 00.56, and both the latest Android (2.6.0.4) and iOS (2.5.0.3) apps can now create robots that respond to motion.12/25/2014 - Better, but still No. Downloaded updates for Android, iOS, and hub firmware yesterday. This appears as a motion sensor under the new sensors category in the app. Blue light on hub flashes green when motion is detected, and sensor status shows motion detected. But robots can't select the motion event as something to detect.12/7/2014 - No. If you use the hub's z-wave controls to include it, it will show up under Sensors as a generic Spotter. The app indicates that it's on battery power and has only motion and light sensing enabled. So far so good. But no signals are ever received.
Question: Does it work with the SmartThings hub
Answer: Turn the Ultrasonic dial to level "4" for the highest sensitivity. You can also select Option 1 for the Trigger Mode so that the sensor catches as much movement as possible.
Question: Will this work with the Wink hub
Answer: I did not. Just connect load to load, white to white, and ground to ground. If you it’s 3 way switch, also connect red to red.
