What's the difference between digital camera and network camera in monitoring system?
Digital cameras include three mainstream products on the market at present: network cameras, SDI cameras and network cameras. Network cameras belong to one kind of digital cameras.
The digital camera collects video signals and then converts them into digital signals for output. Generally, signals are not compressed, so the definition is high, but at the same time the bandwidth is also large. The output signal is usually input to dvr, video matrix processing, storage array, etc.
Network camera also collects video signals and converts them into digital signals for output, but when it outputs signals, the signals are compressed in a large proportion, and the distortion is higher than that of digital cameras. But it is precisely because of this that signal transmission is more convenient. Just like upstairs, it can directly access the Internet through RJ45 cable to enjoy resources.
