Exporting an archive from an Ajax NVR via USB enables users to download videos locally to a connected storage device without Ajax apps or an internet connection.
System requirements
All Ajax NVRs with HDMI output, running firmware version 2.547 or later, support exporting video recordings to an external storage device via the USB port.
An Ajax video recorder can export an archive to a connected storage device, such as an HDD/SSD or a USB flash drive. HDD and SSD drives must be connected to the USB port via a special adapter and require an external power supply. The following storage device file systems are supported: FAT32, exFAT, and ext4.
Use an external power supply if the storage device requires more power to operate than the USB port can provide.
Operating principle
Ajax NVRs with HDMI output can export video recordings to an external storage device connected to the USB port. This allows users to download videos directly from the video recorder connected to the display via HDMI. No Ajax apps or internet connection are required.
Only local users and users with a cloud account who have the rights to view and download videos from the archive can export video recordings via USB.
When an external storage device is connected to the video recorder via USB, you can perform the following actions in the selected camera’s video player:
Select the storage device you want to use if multiple devices are connected to the video recorder.
Navigate between the folders on the storage device.
Manage data on the storage device, such as creating folders and deleting folders or files.
Format the storage device (to the exFAT file system).
Video recordings downloaded from an Ajax NVR have an Ajax digital signature, which verifies the integrity of the exported video. To verify the authenticity of downloaded video recordings, use the Ajax Media Player tool.
