Camera connection

Possibilities for connecting cameras available in the registrar.

For analogue DVRs and digital NVRs (see "Type") in this case, everything is simple: the number of video channels corresponds to the largest number of incoming video signals that can be connected to the device. Such a signal can come both from a camera and from an intermediate device — for example, a quad that combines a picture from 4 cameras. But in hybrid HVRs, the meaning of this paragraph is more specific. For these recorders, this specifies the maximum number of inputs that the device can handle in AHD only mode (i.e., analogue cameras only, no IP cameras). Data on hybrid mode (AHD+IP), as well as for using only IP cameras, are given separately for such recorders (see below).

Numerous channels ( 32 channels, 64 channels and even 128 channels) allows you to create an extensive video surveillance system based on the registrar without using additional equipment (for example, the same quads). On the other hand, this characteristic significantly affects the price, and for living conditions, registrars for 4, 8 or 16 cameras are quite enough.

USB 2.0

The number of USB 2.0 ports provided in the design of the registrar. USB is a universal interface for connecting various peripheral devices. In the case of registrars, we are most often talking about "flash drives" and other external media that can be used to copy files or update firmware. However, compatibility with other devices, such as manipulators (keyboards or mice), may also be provided.

Specifically, USB 2.0 allows you to transfer data at speeds up to 480 Mbps and provides a relatively low power supply. Because of this, this version is generally considered obsolete and is gradually being replaced by more advanced standards (primarily USB 3.2 gen1 - see the corresponding paragraph). However, USB 2.0 connectors are still very popular in registrars.
