Window Security Cameras: What to Look for & Where to Install

Wanna install a window security camera to add an extra protection layer for your home? A smart decision! According to the home burglary statistics, 23% of burglars break into a home through a first-floor window. The security cameras for windows would be a powerful deterrent to home thefts and burglary. Here you’ll know what to look for in a window sill security camera, and if it is feasible to use a security camera through a window.

Here is the key information for you when you want to buy window security cameras:

What for Choose window security cameras
Features Weather-resistant/vandal-proof
Recommended Camera Reolink security cameras
Camera Types Argus 3 Pro/RLC-511WA

So, Can You Use a Security Camera Through a Window

First off, let’s start with the questions you concern the most, like

Can you place a security camera inside or behind windows looking outside? Will the security camera motion detection work through windows? And how to prevent the security camera glare/reflection through windows?

Actually, in our prior post, we have already discussed whether home security cameras can work through windows (with solutions), and below are the quick conclusions:

  • For infrared security cameras behind glass windows, the IR illuminators will be reflected back from the windows into lens, leading to washed-out images.

To reduce the security camera window reflection or glare, you may choose the window security cameras that allow you to turn off the LED lights via the app, like Reolink RLC-422W, and then mount IR illuminators or automated external lights that can provide light source for the camera outside.

External IR illuminators

  • As for the motion sensor security cameras on window sills that work by comparing the changes of consecutive frames, the security camera motion detection won’t be affected through a window.

But not for the window security cameras with PIR motion sensors that detect motion movement by sensing the changes of heat.

As most glass used in home windows today is insulated, it will block heat transmission which is needed for the PIR motion sensors. And that's mainly why the PIR security camera motion detection can’t work through windows.

Essentially, it all comes down where you should place a window security camera for its optimal performance.

Since mounting security cameras inside windows towards outside could incur the unwanted reflection or glare, it is more sensible to install window surveillance cameras between window and screen, out 2nd story window, or hide the cameras in plants.

Window Security Camera Installation

Editor’s Tip: Besides installing window security cameras, check out more useful and inexpensive ways here to secure your home windows.

What to Look for in Window Security Cameras

To quickly land you on the right window security cameras, here are several factors you should consider during your selection process.

1. Weather-Resistant & Vandal-Proof Design

As mentioned above, the security cameras for windows are most recommended to be mounted outdoors to prevent glare or reflection, which means they need to be weather-resistant enough to withstand all harsh weather conditions.

If you are worried that your window security cameras might be damaged or removed by bandits, a vandal-proof window IP camera, like the Reolink RLC-422W with IK 10 vandal-proof rating would be the ideal security solution.

IK Rating Meaning

And by the time someone manages to take away your window mount wireless security camera, you would have received instant alarms and captured the face of intruders.

2. Easy Installation with Minimum Cables

To avoid the possible problems caused by security cameras behind windows, you may have to climb a ladder to install the window security cameras outside.

Any way to get rid of the complex and troublesome installation process?

Absolutely yes – the wire-free battery powered security cameras, like Reolink Argus 3 Pro, require no messy cables and no drilling holes. Simply insert the battery into the window sill security cameras and they’re ready to go.

When you need to remove the battery home window security cameras to another site, you can easily take them done and reposition them in a new site as you wish.

The battery powered security camera Reolink Argus 3 Pro is highly portable and can be placed anywhere you wish. It is not only suitable to be a security camera for windows, but also for your front doors, back doors, backyard, garage, farm, barns, etc.

3. Good Day & Night Vision of Window Mount Cameras

“I need a window security camera with night-vision capability to see everything in front of the house, can I do it?”

Just to emphasize again, the IR security cameras can’t work through glass at night unless you turn off the built-in LED lights and mount external IR illuminators.

But that would bring you more trouble as well as higher cost.

The shortcut is to buy a security camera for windows with good day and night vision capability (at least 1080p) and mount it outside your windows.

And the most reliable way, based on thousands of buyers’ experience, to tell the image quality of home window security cameras is to watch the video samples shared by real users.

For example, below is the night vision video shared by a user of the security camera, Reolink Argus 3 Pro.

4. Storage Option of Window Security Cameras

With so many security camera recorders available, you need to decide where to store the footage of your window security cameras based on your specific situations.

So, if you have mounted multiple security camera for windows, front doors, backdoors, garage, driveway, etc., the best way to manage all these security cameras simultaneously is to buy a dedicated NVR (note that some NVRs are only compatible with the cameras of the same brands.)

Or in case you’d like to save the videos of window sill security cameras onsite, the security cameras with SD card (slot) could be also a handy option. And you can also back up the footage to the cloud storage if you have enough budget.
