UN1A-16X8 and UN1A-32X16: Going beyond the Plug-and-Play port count

UN1A-16X8 and UN1A-32X16
Going beyond the Plug-and-Play port count
ULTRA-IP NVRs have a fixed number of Plug-and-Play ports on the rear panel. The maximum number of fully
Plug-and-Play cameras supported by an ULTRA-IP NVR is the same as the number of Plug-and-Play ports on
the rear panel. In addition, the maximum number of IP cameras that can be connected through the PoE switch
on the rear panel is the same as the number of Plug-and-Play ports on the rear panel*.
For the UN1A-4X4 and UN1A-16X16XL, that is rather straightforward. Cameras can be connected as Plug-and-
Play to the PnP ports. Cameras can be connected as “manual” configured cameras through either the PnP ports
or the LAN/WAN network port. Either way, on these two models, the maximum number of connected cameras
is exactly equal to the number of PnP ports on the rear panel. If any camera is connected via the LAN/WAN
network port, that is one less camera that can be connected to one of the PnP ports.
The UN1A-16X8 and UN1A-32X16 are a different story. Each is capable of connecting up to twice the number of
cameras as there are PnP ports on the rear panel. Given that a maximum of 8 cameras can be connected
thought the PnP switch on the rear of the UN1A-16X8 and a maximum of 16 cameras* can be connected
through the PnP switch on the rear of the UN1A-32X16, how are the additional 8/16 cameras connected?
They must be connected through the Gb/s LAN/WAN network port on the rear panel of the NVR.

*While additional cameras may be connected to the internal switch, as the switch capacity is 100Mb/s spreading that bandwidth across
more than 16 cameras may reduce system performance and reliability.
Does this mean that for the additional 8/16 cameras, or any cameras connected though the LAN/WAN port
there is no Plug-and-Play convenience? Not exactly. Depending on the network setup, if they are KT&C Plug-
and-Play capable cameras, it is possible to quickly and conveniently set up and access those cameras.
