TVI-Firmware Upgrade

A firmware upgrade allowing for the use of SPD and other recovery apps should a password be lost.

To upgrade, simply follow the attached the instructions in this message, as well as download the firmware upgrade below.

Follow the instructions in Section G, which require you to copy the software upgrade to a USB drive, and then plug that drive into the rear DVR USB Port.

Then power the system off, then on and the software should be upgraded.

Make sure to download and use the correct update for your system. If the DVR is 720p, download the 4CH 720p DVR folder, if it's 1080p, download the 4CH 1080P folder.

These upgrades are only for 4 channel TVI units, do not attempt to upgrade any other unit besides these.
