How to Use Extended Transmission Mode

Long Distance POE/Data Transmission

One problem that a lot of installers run into with IP jobs is Cat5E cable length limitations. With the cable
limitations this requires that some job sites have extra equipment installed such as another switch or
extender. Installing extra devices not only creates more fail points on the job site but it can drastically
increase the price of the job. Uniview offers an incredible solution to this problem! Using Uniview built
in PoE recorders cameras can now be ran up to 300M (900 FT) over Cat5E plenum.

Enabling Long Distance Mode

Enabling long distance mode is very simple, log into the main menu of the recorder and navigate to the
Camera menu. In the camera menu each channel that has a PoE port built in to the recorder will already
have a channel spot reserved for them with an IP address. Double click on one of the reserved channels
to display the channels Modify menu. The last option in the Modify menu will be a check box to enable
Extended Transmission mode. Check this box on and then click the Modify button at the bottom.


Using A Uniview Switch

There is a small extended mode switch in the bottom corner of each uniview switch, this switch comes
off by default. Enabling this switch can give the same performance as a built in PoE switch when it
comes to long distance transmission. Installers will need to use Cat5e Plenum cable though. Each
Uniview PoE switch also comes with at least one gigabit uplink port and one fiber port.

Enabling The Extended Mode Switch 

  1. Power on the switch without plugging anything into it.
  2. Turn the extended mode switch to the “on” position.
  3. Unplug the switch / Turn off the switch for 30 seconds.
  4. Power the switch back on.


The switch will be in extended mode when the switch comes back on. Once in Extended mode the PoE
ports will all act individually without the ability to see the other PoE ports. Make sure that the NVR is
plugged into the gigabit uplink port otherwise it will not be able to see the cameras. If daisy chaining
switches together the gigabit or fiber ports will need to be used to link each switch and then connected
to the main network using the first switches second uplink (8 port switches cannot daisy chain without
an extra dummy non PoE switch to link everything.)

If daisy chaining switches together each switch will need to be link together by each switches uplink
ports. The NVR would then be plugged into the first switch in the chains second uplink port. And the
internet would need to be plugged into the last switch in the chains second uplink port.
