What are surveillance cameras? A surveillance camera is a device that captures an image or video of a person or an object. There are two kinds of surveillance cameras: analog and digital. A typical analog camera has an image sensor to capture the image, a lens that converts the image into visible light and a lens cover to protect the lens.
A digital camera captures the image in a digital format. The image sensor of a digital camera is also used for capturing the image in an analog format. Some newer digital cameras also have the ability to capture video.
Analog cameras
Analog cameras capture a color image that is transmitted over a low-power analog line. The image on the analog line is transmitted to a television set and viewed by the person. Some analog cameras can also be connected to a digital camera to send the video from the camera over the analog line to a remote television.
Digital cameras
The digital camera captures an image by using an electronic image sensor and converts it into a digital format. This digital image is transmitted over the high-power digital line and is available on a personal computer. You can send the images over a local area network or Internet.
The analog and digital cameras have certain features that distinguish them. For example, the analog cameras can not record a continuous video in a single file. You can transfer the images from one camera to the next. With a digital camera, the images can be stored in a single file.
