Note: Read this article on how to update the firmware on an H.264 DVR. Below is the whole list as sourced from Uniforce. So, be careful because you may end up damaging the unit and losing the recorded footage. However, in some certain DVRs, especially the older ones, the wrong firmware may go through and the DVR will get bricked. Most of the time, nothing will happen when updating with the wrong firmware, the DVR will just refuse it and automatically reboot. If you can access your DVR, navigate to the Version section (usually under the Information section) and check the current version as shown in the picture below.Įither way, don’t update the DVR or NVR if you’re not sure about the firmware. If that’s the case, we recommend contacting your seller and getting the firmware from them (or let them give you the original manufacturer’s model).Īdditionally, you can check the sticker on the DVR and google the model number for any possible hints (or try to google the DVR’s chipset). Sometimes the seller/dealer changes the brands of the DVRs or uses their own model numbers in an attempt to hide the true origin of the product. Inspect the list below to get firmware that matches your hardware model/version. If you can’t find your DVR model, then open up the DVR’s cover and lookup for the chipset model (as shown in the picture) typically there is a printed hardware model/version on it.
