NOTES:

• It may take up to 1 minute for cameras to start up and transmit video to your recorder.

• This guide covers connecting IP cameras to your security recorder only. For full instructions on

installing your cameras, please refer to your camera’s documentation at lorex.com.

• Connecting cameras to a router, or a network switch without PoE, requires a power adapter for

each camera. Refer to your camera’s documentation at lorex.com for the correct power adapter

model number.

NOTES:

• If you are using a PoE switch, ensure the switch is connected to the same network as your

recorder.

• To receive automatic rmware updates and enable remote viewing with mobile apps, a high

speed Internet connection is required (minimum upload speed of 5Mbps required for 4K viewing;

3.5Mbps for lower resolutions). All other system features can be used without an Internet

connection.

The NVR stores recordings on an internal hard drive and allows for backup to external USB flash drives.

Usage Features

Initial Setup:

The Quick Setup Guide outlines a straightforward process for getting the NVR operational.

Connect Cameras: Cameras can be connected directly to the NVR's PoE ports or to a PoE switch/router on the network. It's recommended to test cameras before permanent installation. The system may take up to a minute for cameras to start transmitting video.

Maintenance Features

Backup Recordings:

Recordings can be backed up from the NVR's hard drive to a USB flash drive.

Insert a USB flash drive into a free USB port on the recorder.
From live view, right-click and select "Main Menu," then "BACKUP."

- Select the desired recordings and click "Start" to begin the backup, or use "Onekey Backup" to back up all matching files.

Changing the Recorder's Output Resolution:

To ensure optimal picture quality, the NVR's output resolution should match the monitor's highest supported resolution.

From live view, right-click and select "Main Menu," then "Display."
Set the "Resolution" to match the monitor (e.g., 3840x2160 for 4K, or 1920x1080 for 1080p).
