TRENDnet TV-IP310pi Night Vision Fix

Let’s face it, it’s not fun when things don’t work properly which is why I was a little annoyed recently – very big understatment! – when I discovered my TRENDnet TV-IP310pi cameras had a slight flaw, a flaw which is scarcely documented but fairly fundemental to the overall use of the camera… oh and did I forget to mention I own 5 of these cameras, all installed around my house, all which had the same problem? Yup!

So what is the actual problem?

Well the cameras work perfectly in the day delivering 25 frames per second of crisp 1080p footage which is great BUT when the night time comes – as it does – performance takes a dramatic hit and you are lucky to get a maximum of 4 frames per second… which is pretty rubbish! For months I’ve been thinking it  was a problem with my home server – an Intel I7 920 quad core 2.4GHz  running VMware – and I came to the conclusion that I needed a new rig as it just couldn’t cope with the amount of data passing through but oh was I wrong!

Anyway, long story short after pestering my friend Chris at work – who also runs his own CCTV system, only with the identical Hikvision DS-2CD2032F-I cameras – some extensive testing was done – I’ll spare you the details – but we came to the conclusion that the hardware was good, the network was good and were stumped until we found an Amazon review which also mentioned the same problem!

This unfortunatley opened up a can of worms and what followed was a very stressful 3 days which involved not sleeping much, scouring forums, downloading all sorts of firmware and almost losing ALL hope and contacting support! However, I’m very pleased to report that all of my cameras are now running the latest TRENDnet firmware – v5.3.4 – and are delivering 25 FPS 1080p footage at night time – Wow!

So how easy is it to fix?

The fix is easier than you might think, but you do need to be brave as we are essentially going to ‘brick’ the camera and make it an expensive paper weight by installing the Hikvision firmware, then we will reload the TRENDnet firmware fresh and enjoy ALL the frames per second! You might think this is a mad idea, but the TRENDnet TV-IP310pi is actually a rebranded version of the Hikvision DS-2CD2032F-I, so deep down the hardware is the same it just has a different sticker on the side.

I used the following files found below, combined with an XP laptop that was connected by cable directly to the PoE switch, this was connected to the camera directly and ideally  you’ll want to unplug all other devices so you only have the camera and the laptop plugged in but I might have got a bit lazy towards the end… Also, my Windows 7 laptop struggled to transfer the firmware as the TFTP file transfer kept looping and wouldn’t complete, hence using an old XP machine.

I’m up for the challenge!

Great! Before you continue please be aware that I won’t be liable if this goes wrong and it will reset your camera back to the factory default settings! I’ve done this process 5 times flawlessly so far but still – proceed at your own risk!

Whenever the camera boots it scans a predefined IP for a TFTP server, if it finds this server it looks for a specific file and because of this we can do the recovery without having to open the camera up or get ‘hands on’! I reflashed all my cameras with them still fixed in position on the house, minimal effort required!

  1. Download the files found here, extract them somewhere safe and keep reading
  2. Change your computers network settings so the IP address is 192.0.0.128, see picture below:
    trendnet_tv-ip310pi_recovery-network-config
  3. Connect your computer to the switch along with the camera, disable any other connections network – FLASH VIA ETHERNET CABLE ONLY!
  4. Copy the Hikvision_5-1-6–digicap.dav file into the TFTP Server folder and rename it digicap.dav
  5. Run tftpserv.exe and then restart your camera, after a few seconds you should see the following:
    trendnet_tv-ip310pi_recovery-tftp1
  6. Now you won’t get any confirmation here, so leave it 2 or 3 minutes then unplug your camera, close the tftpserv.exe and repeat step 3 but this time use the Trendnet_5-3-4–digicap.dav file
  7. Now start tftpserv.exe again and connect your IP camera, this time after a few minutes you’ll see a system update complete message like below:
    trendnet_tv-ip310pi_recovery-tftp2
  8. Close of tftpserv.exe and reboot the camera, after a few minutes check your router and you’ll have a fresh IP camera sat on DHCP waiting be configured! If you can’t find your camera straight away, don’t panic! Install the auto discovery program (SADPTool_V3.0.0.100.exe) and find the camera that way

Conclusion

I did try updating to the latest TRENDnet firmware via the web interface before going down the TFTP route but it still gave me low frames per second at night using the identical 5.3.4 file… I’m guessing installing the Hikvision firmware first completely screwed things up, after that the camera is left fresh, ready for the TRENDnet firmware? Either way it worked and I’m a happy nerd!

Notes

  • Again, I can’t be liable if this goes wrong for you!
  • The files in the link above were all found on the Internet, I take no credit, all  credit belongs to the respective authors (presuming that is Hikvision? Thanks!)
  • If you get really stuck I can reflash your cameras, after all not everyone has an old XP relic lying around! Drop me an email, pay for postage and send your camera in a box along with a little gift!
  • I found an easy way to tell the camera state during the reflashing process which is to do a constant ping to the IP addresses below – Note that in order to use this method you’ll need to assign your network card two IP addresses (192.0.0.128 and 192.168.1.128):
    • 192.0.0.64 – Camera is in rescue mode
    • 192.168.1.64 – Camera firmware has updated but not yet rebooted
    • No response from either – Somethings not right!
  • You can find the latest TRENDnet firmware direct from their website here
  • From various forum posts I read some people were saying you can flash using any TFTP server software, however this isn’t the case as you must use the Hikvision TFTP server as there is a special initiation process which waits for certain key to be sent back and forward before the firmware updating process begins
  • Make sure you clear your browser cache before logging in again otherwise things might not work properly

Webmin 1.610 on CentOS 5.8 (x86)

The following commands can be used to install Webmin 1.610 on CentOS 5.8. Make sure you’re logged in as root and then follow the steps below.

Select a temporary directory to save the download to. We will only use the downloaded file once so it’s pointless keeping it.. free up space and put it in /tmp!

cd /tmp

Begin the download of Webmin using wget:

wget http://prdownloads.sourceforge.net/webadmin/webmin-1.610-1.noarch.rpm

Install Webmin by unpacking the archive:

rpm -Uvh webmin-1.610-1.noarch.rpm

Done! You can now login to your fresh installation of Webmin by heading to http://hostname-or-ipaddress:10000 using the root username and password.

Notes

  • You can download the file used in the example above by clicking here
  • If you don’t have a server to try this on I’d recommend DigitalOcean hands down – virtual servers start from $5 a month

Virtualmin GPL on CentOS 5.8

Update: 08/03/2017: The following guide was originally written many moons ago for installing the Virtualmin GPL (free) control panel on CentOS 5.8 x86, however it will work exactly the same on the current version of CentOS (7.0).

The following guide will assume you are logged into your CentOS machine via command line, ready to enter the following commands.

First you will want select a temporary directory to Virtualmin installation file to. We will only use the downloaded file once so it’s pointless keeping it, so to free up space and put it in /tmp!

cd /tmp

Download the Virtualmin GPL installer:

wget http://software.virtualmin.com/gpl/scripts/install.sh

Run the installer:

sh install.sh

The installer will then launch and prompt you to approve if you’d like to proceed. Simply type “y” and press enter and the installation process will begin.

After a short while you will see a message saying the installation has been completed. You will then be able to login to installation of Virtualmin by heading to https://hostname-or-ipaddress:10000 using the root username and password.

Once logged in you will then be guided through a final configuration process, once completed the installation will be complete and ready for use. Another guide will be written soon to explain how to configure Virtualmin.

Notes

  • You can download the original .sh file used in the example above by clicking here
  • If you don’t already have a server to try this on check out Linode, they offer reliable good spec servers starting from $5 a month
  • Depending on your CentOS installation you may get an error message about the Perl package being missing. To resolve this run the following command in terminal and then relaunch the installer:
    • yum install perl -y

Upgrade Windows Phone 8.0 to 8.1 Before Main Release Using Developer Preview

Recently I lost my smartphone and after lots of searching decided to give up and buy a new phone. As I only really use my phone for checking emails, a little remote desktop access and the odd bit of mobile banking I didn’t need anything overkill and I fancied a change from Android so I went for a Windows based Nokia Lumia 520.

The Lumia 520 can be picked up for £69.00 on O2 pay as you go (as of 01/07/2014, see here) but I paid a little extra and got mine the same day. I was initially blown away by the Windows Phone operating system as it was better than expected and I couldn’t find any flaws. I’d setup my email, installed the mobile banking app and so on which lead me to my final task which was to install the Remote Desktop app. You’d think this would be a straight forward task installing a Microsoft product on something Microsoft powered but no, when heading to the Microsoft Store on the phone the Remote Desktop app wasn’t showing so I searched the Microsoft Store online and it came up saying that it wasn’t compatible with the Windows Phone 8.0 operating system that was currently on the phone.

I had three options, to cry in the corner, wait for the update to be released or to try upgrade the phone manually. After a little research the update was said to be released within the “…first two weeks of July…” but there was no exact date and I just couldn’t wait.

After more research it turns out that you can use a free app called Preview for Developers which allows you to basically get the update there and then instead of having to wait.

Upgrading Windows Phone 8.0 to 8.1

Below you’ll find a guide on how to upgrade the Windows Phone operating system. Please note that any changes you do here are irreversible and this will no doubt void your warranty.

  • First things first we need to create a free account with Microsoft’s App Studio using the link found here as this will give you access to the developer previews service and give you the magical updates – I used my main Microsoft account that’s linked to the phone to keep things simple
  • Once you’ve created the account go to Microsoft Store on the phone, search Preview for Developers and install the app
  • Once the app has installed launch it and you will be asked to accept the terms and conditions and login using the account details created previously
  • Next you’ll see information about what the app does and so on, all we need to do here is tick the box next to Enable Preview for Developers and press done
  • Now that’s enabled head to Settings > phone update and press check now and then follow the on screen instructions – You may need to repeat this process several times as it took me two updates to prepare the phone before the update to Windows 8.1 was offered
  • After a little while you will now be running Windows 8.1! – You can check this by viewing Settings > about > more information under the OS version heading

Notes

  • Make sure your phone is fully charged before attempting any updates as things could seriously go wrong otherwise!
  • As with anything in development stages things may be a little buggy so be aware that you may stumble across the odd glitch every now and again
  • Although not tested I assume the same steps will work for phones other than the Nokia Lumia 520, if you can confirm this I’d be grateful
