Uniview camera firmware is updated on a regular basis, so it's best to use the 'Batch Upgrade' feature in the NVR menu. You can also use the 'Online Upgrade' button within EZTools.
Due to the large number of models and versions, it is not practical to keep this page up to date. If you require a firmware file for an offline upgrade, please contact firstname.lastname@example.org and the team will be happy to supply it to you. It is essential you mention the full product code for the camera.
