People also ask
- What is a lens in CCTV?
The simplest CCTV lens is a piece of glass (or plastic) to focus the light from the outside world onto the camera’s imaging sensor. This lens’ only adjustable mechanism is its focus-ring, part of the barrel body, which you turn until your image is as clear as possible. - How to choose CCTV lens?
This means that for areas like the front door where you are capturing someone 1-4 metres away, 2.8mm is ideal. Sides of homes, 4mm may be more ideal. Driveways which are say 10 metres long will get more ideal image with 4-6mm if what you’re trying to see is closer to the entrance of the driveway. - Can CCTV listen to you?
Can CCTV Cameras Pick Up and Record Sound? In short, yes, they can. CCTV cameras can record audio, although this works differently depending on whether you have IP CCTV cameras or more traditional analogue cameras.
