I'm just wondering if when a DVR says it has 4 ports, if that means
RJ45 for IP and BNC for analog cameras.
thanks
RJ45 for IP and BNC for analog cameras.

Most DVRs only have inputs for analog cameras. Then if equiped they provide
one RJ45 for IP networking to connect to them.

If you have a four port DVR with a single RJ-45 then it will have four
analogue camera inputs and no IP camera inputs, the RJ-45 is to connect the
DVR to the network to allow remote viewing of the system, not to accept
inputs from IP cameras.

Roland said:For the most part a 4 port DVR means 4 BNC type analog camera inputs. Some
really low end units might have use RJ-45 or RJ-11 connections instead of
BNC for "kit" units with their own cameras.
However traditional DVRs in general and especially the kit types are
rapidly becoming as old school as a VCR.
Most all IP cameras support PoE. You do have to double check the power
availability on the switch you select to match the camera load.
In the mega pixel camera market most all cameras are IP based.
Most DVR units, even hybrids, aren't made with enough IP through put
or retention capacity for more than one or two IP mega pixel cameras.
Just said:Plug the cameras and DVR into the same network
switch, [!!!***hub***!!!] or router, and you're good to go.
Most encoders like Verint, Bosch etc. NEVER want you to use a hub. One of
the first checks I make is to see if there is a hub in use. If there is, it
is a show stopper until it is replaced.
