4RE - Upgrade the DVR firmware

Introduction

Firmware is the programming, or set of instructions, for a hardware device (more information). The firmware for the 4RE is occasionally updated to add new features and bug fixes.

Procedure

Visit the 4RE - Downloads page to download the latest firmware release.

IMPORTANT: In order to upgrade to version 4.0.1.xxx or higher, the 4RE must be on version 3.6.7.179. For a wireless deployment, all cars must be updated to the 3.6.7.179 version.

If your version is lower, you will need to upgrade to 3.6.7.179 first, then you can upgrade to 4.0.1.101 or higher. Visit the 4RE - Downloads page to download this version.

If downgrading the DVR version (not recommended) the DVR will format the hard drive and all video will be erased.

IMPORTANT: When upgrading via USB, ensure all video has imported prior to processing any upgrades or updates on your 4RE units.
