Why do ISS cameras have dots?
Many of the modules have these dots within circles mounted on the exterior. They are targets that are part of the no-longer-used Space Vision System (SVS).
Does a camera work in outer space?
Cameras used on spacecraft are similar to digital cameras, except a lot tougher and a lot more sensitive. Instead of film, cameras on spacecraft have special light-sensitive devices similar to computer chips. These are called charge-coupled devices, or CCDs. Each filter lets through only a certain color of light.
Is ISS live really live?
People have been getting very excited about videos from the International Space Station (ISS) apparently broadcast “live” on Facebook – but they are not what they appear to be.

How to protect your surveillance camera system from hackers?

Let that sink in for a moment…these companies do not even use the type of cameras they are selling to the public, and there is a good reason why.
What is the difference between 360° & 720° surveillance cameras?
360° & 720° surveillance cameras use a specialized fish eye or spherical camera lens to offer a far wider viewing area compared to a normal/standard camera. 360° cameras can see in all directions, though in one hemisphere only. 720° cameras can see in all directions at the same time…up/down and left/right.
