Choosing the correct CCTV Camera for your digital surveillance system is very important. Typically the Digital CCTV Camera, together with a CCTV Lens, uses a CCD (Charge Coupled Device) sensor that captures the image and turns it into a signal that is sent to the monitor or surveillance system.
You will need to decide the following when choosing a cctv camera & lens for a digital cctv system:
- The Digital Camera Location: Will the camera be situated Indoors / Outdoors
- The amount or variance of light conditions for the digital cctv camera: Will the camera have to record in low-light conditions such as at night?
- The Field of View required for the camera: How wide or narrow an angle of vision is required
- The Focal Length - How far away objects you wish to record will be from the camera
