Thinking about setting up a trail camera behind a window to capture some backyard wildlife or add a bit of extra home security? It sounds like a smart and simple idea. Just place the cam on a windowsill, close the blinds behind it, and wait for the footage. But there’s one problem that catches most people off guard: trail cameras and glass don’t always get along.
So, can trail cameras see through glass? Technically, yes. But in most cases, they won’t work the way you expect. Here’s why.
Why Glass and Trail Cams Don’t Mix Well
Trail cameras rely on infrared (IR) sensors to detect motion, especially at night. These sensors need to pick up heat changes from moving objects, which glass tends to block or distort. That leads to two main issues:
1. Motion detection won’t work properly
Because IR sensors can’t see through glass effectively, your camera might not trigger at all when something moves outside.
2. Night vision gets ruined by glare
At night, the camera’s infrared lights reflect off the glass and bounce back into the lens. You’ll likely end up with washed-out images or nothing usable at all.
What About Daytime Recording?
You’ll have better luck during the day, when infrared isn’t needed. If you’re only interested in recording video or taking snapshots during daylight, some trail cams can still give you decent results through a window.
But remember, the motion sensor still won’t work. Unless your model has a time-lapse or manual mode, it may not capture anything useful.
Using Trail Cameras Indoors
Trail cameras are designed for outdoor use, but they can still come in handy indoors in the right setting. If you’re using one inside, try these tips:
- Avoid placing it behind glass or shiny surfaces
- Point it at open spaces like hallways or large rooms
- Use time-lapse or scheduled recording modes if motion detection isn’t reliable
- Keep it steady and positioned at entry points if you’re using it for basic security
It’s not a perfect substitute for a purpose-built indoor security cam, but for general observation, it can do the job.
Are There Trail Cams That Work Through Windows?
If you’ve been wondering whether you can use a trail cam through a window, the short answer is: not reliably. Even the best trail cameras in Australia tend to struggle with this kind of setup. That’s because infrared motion detection and night vision don’t work well when trying to shoot through glass. The technology simply isn’t designed for it.
When it comes to using a trail camera indoors, you’ll get better results if the camera isn’t placed behind glass. Set it up inside an open room, hallway, or garage to allow the motion sensors to function properly. Just be mindful that most trail cams are optimised for outdoor use, so results may vary depending on the model.
If you’re looking for clear, dependable footage, the better choice is to mount your camera outside, where it can operate as intended. Here are a few tips that might help:
- Use external motion sensors with the camera if your model supports them
- Mount the camera outside with weatherproof brackets
- Try a solar-powered model for areas with limited power
- If you're after indoor monitoring through a window, a standard home security camera may work better than a trail cam
