Taking the noise reduction for example, the higher the noise reduction is, the worse the CCTV camera ghosting effect becomes.

Solution 2: Clean your security camera lens on a regular basis to get rid of the possible smudges, bugs, fingerprints, dust, etc., thus removing the possible CCTV camera ghost effect.

Now read through the following scientific explanations to figure out what causes ghost images on security cameras as well.

Solution 6: Ghost caught on security cameras could also be the result of bad connections or a ground loop. If so, you may get a ground loop isolator to remove the security IP camera ghost effect.

Or in some cases, the CCTV camera ghost video is just a prank or hoax for fun. After all, almost everyone loves a good ghost story.

Hopefully, this scientific explanation has shed some light on the mystery of what causes ghost images on security cameras. If you have experienced ghosting issues with your CCTV camera, you can try the practical solutions mentioned to address the problem.

Solution 4: Choose higher resolution security cameras, like 4K security cameras to obtain more image details. And this will help you pinpoint things often mistaken for surveillance camera ghosts, such as reflections and video artifacts.

Infrared Linear Variable Filters are narrow band filters where the Centre Wavelength (CWL) changes with distance along it’s length, this is shown in the diagram below for a 2.5-5.0 µm type. Our range of stock LVF s allow the user an opportunity to explore the technology but at a relatively low cost.

Truth is, however, the ghost caught on camera from Youtube, instead of being the evidence of apparition presence, are merely the results of good editing with graphics or animation software.

Actually, even a high resolution security camera is also likely to (much less odds compared with low-resolution ones) capture ghost-like images due to other factors like unnoticed shadows or reflections.

The purpose, as we’ve discovered, is easy to understand – the unscrupulous photographers are keen to grab your eyeballs and bring a viral hit for more profit.
