Why is my security camera fuzzy at night?

Basically, the IR lights are what make the security camera see in the dark. However, quite often this IR light bounces back from a close object and comes back “blinding” the camera’s lens (eye). This light reflection is what makes the image show as blurry or foggy.

What causes ghosting on CCTV cameras?

Ghost on CCTV cameras can also be caused by slow shutter speed, high gain, high DNR, high DWDR and smoothing settings. Taking the noise reduction for example, the higher the noise reduction is, the worse the CCTV camera ghosting effect becomes.

Why do snowflakes have 6 sides?

All snowflakes contain six sides or points owing to the way in which they form. The molecules in ice crystals join to one another in a hexagonal structure, an arrangement which allows water molecules – each with one oxygen and two hydrogen atoms – to form together in the most efficient way.

Are snowflakes rare?

“We are photographing these snowflakes completely untouched by any device, as they exist naturally in the air.” “These perfectly symmetric, six-sided snowflakes, while beautiful, are exceedingly rare – perhaps one-in-a-thousand at the most,” says Garrett.
