Traditional analog camera

Remote monitoring requires a digital camera. The differences between the two are as follows:

First, the subject is different.

1. Analog camera: A camera that uses analog signal processing.

2. Digital camera: It is a digital signal processing camera.

Second, the principle is different.

1. Analog camera: The output is an analog video signal. Analog video signals generated by video acquisition equipment can be converted into digital signals by encoders and then stored in computers.

2. Digital camera: Digital component signal Y/R-Y/B-Y can be output after digital processing, which can be directly used by digital component equipment, and analog component signal and composite full TV signal can also be output after digital-to-analog conversion.

Third, the advantages are different.

1. Analog camera: Video data can only be stored locally, and cannot be viewed remotely, so it is not easy to be destroyed by criminals.

2. Digital camera: With the adoption of digital processing technology, many tasks that analog cameras can't accomplish can be realized, which greatly improves the overall performance and image quality of the camera.
