Hi, I was wondering if anyone else has run into issues updating firmware on Annke nvr’s? The nvr my buddy gave me has an older version of firmware version 3.4.97. I’ve downloaded the updated firmware for my model of nvr (N48PAW).

When I try to update from nvr using usb stick I get a mismatch error. When I have the system check for an update it says in broken English that there isn’t a new version available.

when I try from the nvr’s web interface using IE on a windows 7 desktop it also fails. I updated the webplugin for IE but no luck. I tried moving the file location in case it was due to path or folder permissions. Still no luck however the error changed from “progress can’t be displayed “ and failing . After moving file and setting permissions on file I now get an “upgrade failed “.

ieven Try finding the firmware for a hikvision nvr with similar specs, but file type isn’t recognized. I’m currently trying the tftp method, but not sure I fully understand that process. I can’t get nvr to find tftp server.

Any advice would be greatly appreciated.

You really need to be asking yourself why are you updating? If it is just for grins and giggles or OCD behavior to be running the latest firmware, think twice.

A common theme around here is don't fix what ain't broke. If the unit is working and meets your needs, in many instances an update breaks what you had working and provides you with something you didn't need or bricks the camera. In most instances, updates are simply security vulnerability patches (usually years after the breach was found), but since we do not give our cameras internet access, the update is useless to us.

Here are issues I have seen people report here where they were upgrading just for the sake of upgrading:
  • A Dahua Z12E that someone updated and then constantly reboots comes to mind,
  • The Dahua 49225 PTZ that loses autotracking with an update come to mind,
  • A Hikvision ANPR camera losing half the FPS and loses the ability to read US plates - those are big deals to have happen.
  • A Hikvision camera that the user lost ability to control the LED light function at night.
  • Countless other instances where the camera simply bricked and became useless.
  • Countless examples where the camera went into Chinese.
Don't do it unless it is fixing a problem you are experiencing or adds a feature you really need.

Further, it is best to obtain any firmware updates from the vendor you purchased it from so that you do not run into issues. Any firmware you find here or elsewhere is obviously proceed at your own risk. We have many threads here where someone tried an update with a firmware they found on the internet and bricked their unit.

Many units being sold are Chinese hacked units into English that will either brick or go into Chinese upon updating. Some vendors will be upfront and tell consumers that as part of their website, but many do not or the consumer forgets...here is one such example....

Why release an update if they aren’t addressing security flaws or introducing new features?

They will introduce new features in a new model - why add a feature to something someone already purchased....

As I said, most of the time, updates are to fix a bug (which if your unit is working correctly for your needs, why chance it) OR it is to fix some security vulnerability that was probably found years ago and they just now got around to it.

Most of us here do not allow these units access to the internet and instead we VPN back into our own system (not a paid VPN to hide you IP address for illegal streaming and porn) to access our systems remotely. If your system doesn't have access to the internet, then there is virtually zero security risk. Many of us here are running original firmware from when we bought it.

In fact, the NVRs I have had over the years maybe either only had one update or none. It is ironic, but these security devices are not very secure when it comes to the internet, so we simply do not allow them access to the internet.

Got it, I just got the nvr and wanted to make sure it had all security patches. I can’t find any release notes on vendors site, so not exactly sure what the update changes.

I’m going to try setting up vpn for my first time this weekend as suggested. I’ve already created a separate network on my router for the nvr, now just need to create the vpn tunnel.

any tips or suggestions on how to test the security after setting up vpn?

once again thanks, and I do apologize if I’m asking obvious questions. It’s just that I’m new to all this, but do have a little technical knowledge
