In the first part of this article we covered issues such as 1.Potential Problems When Security Cameras Are Used through Glass or behind a Glass Window? and 2.Do Infrared Security Cameras See through Glass/Window?
Security Cameras: Working behind Glass Windows (Part 1)
If you want to find out whether security cameras can work through glass/window, the information is below:
3. Does Motion Detection/Recording Work through Glass or behind a Glass Window?
There are two main types of motion sensors used in security cameras/systems. One is a motion sensor that triggers alerts by measuring changes in pixels, which relies on software algorithm.
Another is the passive Infrared motion sensor that sets off motion alarms by detecting body heat and infrared energy, known as PIR motion sensor.
Security cameras with a motion sensor that calculates changes in pixels will still be able to detect movement and record through glass or a glass window.
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.
Fixes:
To detect motion and record motions through glass or a glass window, placing the camera outside, mounting the camera on the wall or window ledge, installing them under a soffit or overhang.
For example, installing wire-free security camera outside on the wall to keep an eye on areas of interest.
Or choose motion sensor security cameras that detect motion by calculating changes in pixels and place it in the window for daytime monitoring.
4. Tips for Using Security Cameras through Glass/a Glass Window
When you use a night vision security camera through glass or behind a window facing out to monitor front door, front porch, backyard, driveway, parked cars or your property outside, or place a security camera in the window looking down through glass or a glass window, it’s important to consider these following tips of security camera placement, mounting and usage through glass or glass window.
- Tip 1. Disable IR light at night to reduce IR security camera window glare/reflection.
- Tip 2. Get separate IR illuminators for infrared night vision security cameras and put IR illuminators outside.
- Tip 3. Choose a window mount security camera when using through or behind a glass window.
- Tip 4. Use window mounts or wall mounts for security cameras that face out through window glass.
- Tip 5. Try to find an alternative spot to install or place surveillance camera outdoor, for example, soffit, overhang, ledge, exterior wall.
- Tip 6. If possible, leave the window open for a bit when placing infrared wireless security camera in the window.
- Tip 7. If you really need to point the camera out through the glass, try placing the camera close against the window or glass.
- Tip 8. Make sure the room the camera is in is darker than the outside at night.
- Tip 9. Keep the glass panels or window glasses clean so that the cameras catch more details through the glass window.
- Tip 10. Make sure your home security cameras are placed out of reach and can’t be snatched away easily.
