Cameras are versatile tools. As versatile tools they have many versatile functions.

It’s useful to understand all of the functions of a video camera. It can pay dividends later if you understand the ins and outs of your equipment initially.

Focus

Most cameras have automatic focus functionality. All you need to do is angle the camera and it will automatically adjust its lenses to keep an image in focus. However there are cameras that have manual focus. The ability to manually focus the camera is great for a static camera. Once you have adjusted the focus to the optimal setting it will remain that way for as long as the camera is in its initial position.

Zoom

Cameras usually have zoom functions. Long-range type cameras can have very strong zoom functionality, allowing the camera to pick up movement from great ranges. This can be great if you want to pick up potential intruders before they know they are in vision range.
