How many inputs can DVRs provide for multiple cameras and multiplexers?

Digital Video Recorders (DVRs) are designed to handle multiple camera inputs simultaneously, allowing for comprehensive surveillance and recording capabilities. Typically, a standard DVR can support a range of inputs that commonly fall between 4 to 16 channels. This range accommodates various setups, from small-scale security systems with just a few cameras to more extensive systems requiring multiple inputs for numerous cameras.

The reason this range is significant is due to the flexibility it offers for different applications. A 4-channel DVR might be suitable for a small retail store, while commercial buildings or larger installations may require a 16-channel DVR to monitor multiple areas at once. The capability to connect between 4 to 16 cameras means that users can efficiently manage their surveillance needs without exceeding hardware limitations.

Consequently, the other ranges mentioned do not accurately represent the typical capacity of most DVRs, either being too narrow or not representative of common configurations in the field.
