Does blink motion detection work through glass?

Author: Wendell Cummerata  |  Last update: Tuesday, July 7, 2026

The Blink cameras cannot be used to face out a window. Blink's PIR sensor cannot detect motion through glass, so a Blink indoor or Blink XT/XT2 camera positioned behind a window will not create clips when armed.

Can Blink detect motion through the window?

The Blink cameras can not reliably detect motion on the other side of glass. Some users have placed cameras facing out a window or through a glass door to use Blink's Live View option.

Why doesn't my Blink camera work through the window?

The Blink cameras use A PIR sensor to detect motion. Unfortunately this type of sensor is not able to detect movement through glass.

Can motion sensors work through glass?

PIR motion sensor security camera doesn't t work reliably or sometimes doesn't work at all through windows or glass because most glasses used in modern houses today are insulated, limiting heat coming through the glass, which in return undermine motion detection.

Can a security camera detect motion through a window?

Passive Infrared sensors work entirely by detecting infrared radiation (radiant heat) emitted by or reflected from objects. Motion detection behind glass will be unreliable since the infrared radiation will not pass through glass.

Does the Blink Video Camera Work Through a Window?

Can I use a Blink outdoor camera inside?

The new Blink camera packs a punch in a compact, weather-resistant design that can now be used indoors or outdoors with the purchase of the new Blink Weather Resistant Power Adapter (sold as part of a bundle or separately).

Does digital night vision work through glass?

- Digital Night Vision: Digital night vision devices use sensors and processors to capture and enhance images in low-light conditions. Similar to image intensification, digital night vision may struggle to see through glass due to reflections and distortions caused by the glass.

Where should you not place a motion sensor?

The Least Effective Placements:
  • Near Windows. This is a bad location for two reasons. ...
  • Near Heat Sources. A heat source could potentially create a false alarm, so it is a good idea to keep motion sensors away from hot air vents and radiators.

Is there a motion light that works through glass?

Sensitive radar motion sensor

The motion sensor light bulb can penetrate the glass, veneer and walls to detect the motion, the led sensor bulb also can detect the pets. The radar sensor bulb will turn on when it detecting any object moving.

Can you place an indoor security camera in your window to see you outside your house?

FYI: Have you thought of using an indoor camera to monitor the outside of your home through a window? We recommend against that! Indoor cameras with PIR-sensitive motion detection don't work through glass windows.

Why are my Blink cameras not picking up motion?

On your camera's thumbnail, tap More . This menu displays whether Motion Detection is on or off. If Motion Detection is off, tap the Motion Detection button to turn it on. You can also check your camera's Device Settings > Motion Settings to see if Motion Detection is turned on .

Where is the best place to put Blink outdoor cameras?

The best range of detection is within 5 to 20 feet (about 1.5 to 6m) from the camera. By placing your camera higher off of the ground, you can avoid smaller animals causing motion alerts. Mini cameras have been used to detect motion through glass. Remember, this is not the most accurate way to detect motion.

Does Blink have window sensors?

Blink pros and cons

No alarm system or door/window sensors, just cameras and doorbells. Offers both wired and battery-powered devices. Some devices can do both, and battery-powered devices have a two-year battery life.

How do I increase the range of my Blink camera?

Selecting Your Camera's Network Coverage Type
  1. From the Home Screen, tap the More (...) ...
  2. Tap Device Settings.
  3. Tap General Settings.
  4. Under Network, select Camera Network.
  5. From the Network Selection screen, choose either Wi-Fi, Extended Range (XR) or Extended Range Plus (XR+), then tap Save.

What is the difference between motion alerts and motion detection?

The key distinction between these two features is that motion detection is the underlying technology that recognizes movement, while motion alerts are the notifications that inform users of such detections.

Is ring better than Blink?

After testing both, we recommend Ring for its bigger selection of cameras, more advanced hardware, and better app than Blink. Editor's Note: Let's cut to the chase. Ring has better cameras than Blink. But we highly recommend the Ring Alarm 8-piece kit, which comes with entryway sensors, motion sensors, and cameras.

Do motion detection cameras work through glass?

The camera will shoot video through the window but the motion detector will not work because glass blocks infra-red (IR) and the motion detector is IR based.

Is there a security camera that works through glass?

The eufy Indoor Cam C120 stands out with 2K high-resolution imaging and advanced night vision, ensuring reliable surveillance day and night when used as a security camera that works through window.

Do motion sensors work through Windows?

Motion sensors do not work through glass reliably. Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated.

What interferes with motion detectors?

Devices like radios, televisions, routers, or even faulty wiring emit electromagnetic radiation that interferes with the signals transmitted by motion detectors, causing them to malfunction and trigger false alarms.

Where is the best place for a motion sensor in a house?

The best placement for a motion sensor is in a corner of the room that has a good viewpoint of your entryways and easily detect any changes in the room.

What is the difference between a motion sensor and a motion detector?

While a motion sensor typically refers to the actual device that detects motion, a motion detector encompasses the entire system, including sensors, alarms, and control panels. But, these days, you can use either terms to mean the same thing — a device used to sense motion for the purpose of security.

Can a Ring camera detect motion through a window?

No. Unless you get a motion activated camera that has the window in its range. Or if the ring device is close enough to the window to detect motion in its range.

Does the glass block the camera from detecting the light?

Essentially, visible light passes through glass, but glass acts like a mirror for infrared wavelengths (which is why thermal imaging camera lenses are often made of germanium or zinc selenide rather than glass).

How to make a night vision camera work through glass?

Try these tips to find out if you can place an IR camera behind glass and make it work:
  1. Place the camera closer to the glass. This prevents glare from getting between the window glass and the camera lens.
  2. Turn off the status lights. ...
  3. Use motion-activated lights. ...
  4. Put it somewhere darker. ...
  5. Disable it.
