I picked up on your reference from earlier in the thread (see below), “Normal standard cable does not work.” So I’m presuming you mean pre-made cables one might buy in a store.
Pre-made cables are available that will work in place of the Zmodo camera to NVR interconnecting cable, these are Straight CAT, also referred to as Patch Cable:
CAT5 supports speeds up to 100Mbps
CAT5e supports speeds up to 1000Mbps (a Gigabit)
CAT6 supports speeds up to 10-Gigabit
The design of the cable is dependent on a number of things including the number of twists per-millimetre, thickness of the wire, shielding and air-gap, crosstalk, power drop-off etc.
All the above is relatively unimportant when considering the marginally low data rate from a camera.
I've successfully used CAT5 but would recommend CAT5e plus it's easier to get. CAT6 has the added advantage of using larger diameter copper and therefore less power drop on a longer run. The higher data rates are irreverent in these applications.
You mentioned you've had no success with CAT5e or CAT6, I'm presuming you're talking about pre-made cables. I can only think these were NOT, Straight CAT, also referred to as Patch Cable and the normal pre-made cable sold when unspecified. The main criteria being that the pins of the plugs at each end of the cable are connected to like-pin-numbers. eg. Pin-1 to pin-1, 2 to 2, 3 to 3 . . . . . . . pin-8 to pin-8.
Crossover CAT cables do not follow this protocol and should not be used in place of the Zmodo camera to NVR interconnecting cable or they will cause problems.
