    A customer recently asked “Does the Infrared on CCTV Security Cameras Work Through Glass Windows?”

    Infrared CCTV

    Here is the full question he asked.

    I have a first alert H.264 CCTV DVR. My current security camera is a CMOS 420 TVL and I have it inside my detached garage facing out the garage window so I can monitor the backyard and backdoor to my house. The night vision / infrared capability is terrible. The backdoor is about 35′ from the camera and I really cant make out any image once the sun goes down.

    I think part of the problem is that the camera is so close to the garage window that the IR creates glare. The other problem is the camera.

    Do you think the BIPRO-9007 is an appropriate camera for my scenario? If I get the camera but am not happy with its performance, what is your return policy.

    Here is the answer that CCTV Camera Pros provided:

    The IR illimunation of infrared cameras does not work well when placed indoors looking out through a window. I recommend that you mount your camera outdoors for much better infrared performance.

    I recommend that you try this first before spending money to replace your existing camera.

    If you are still not happy with how well the IR works on your camera, I would recommend that you consider the BIPRO-540L6 which you can find here:

    I am basing this recommendation on you mounting the camera about 35 feet away from the back door.

    The BIPRO-540L6 will provide better IR illumination than the BIPRO-9007. Also, the 6mm lens of the 540L6 will provide a more zoomed in view of the door.

    Also the BIPRO-540L6 is a 700TVL camera, so the resolution will be better that both your existing camera and the 9007.

    You can return the camera within 15 days for a full refund if you are not happy with it’s performance. Please note that you can not mount the camera though. Please test the camera by holding it outside in the area for testing. Once a camera is mounted, it is no longer new and can not be returned for a refund.
