Revision History
* Rev. 1.0: Initial release.
Some low quality Ethernet cables with smaller core diameter can seriously reduce the
transmission rate. Use CAT5e or CAT6 cables with a wire gauge of 24AWG for NVR’s uplink
port. A thicker core 24 AWG network cable can off er less resistance than a 26 AWG or 28 AWG
network cable.
Use shielded cables in high noise environments where cross talk and EMI can occur.
IMPORTANT:
Due to the limitation of system resources, the fi sheye's all dewarp modes (including
1O/1R/1O3R/1O8R) can only take place in a 1x1 view cell, for one fi sheye camera.
The onboard PoE are end-span ports.
IMPORTANT:
1. Delete a volume erases the recordings in it.
2. The lift on the 16TB volume limitation also applies to USB3.0 texternal storage.
IMPORTANT:
1. Installation and maintenance service should only be performed by qualifi ed technicians.
2. At all times, maintenance of the inside of the chassis should be carried out after all power is
disconnected.

1. Replacement of a battery with an incorrect type that can defeat a safeguard (for example, in
the case of some lithium battery types);
2. Disposal of a battery into fi re or a hot oven, or mechanically crushing or cutting of a battery,
that can result in an explosion;
3. Leaving a battery in an extremely high temperature surrounding environment that can result
in an explosion or the leakage of fl ammable liquid or gas; and
4. A battery subjected to extremely low air pressure that may result in an explosion or the
leakage of fl ammable liquid or gas.
