Fix TRENDnet TV-IP310pi Corroded PoE Connector

Following Storm Doris back in February 2017, one of my cameras at the back of my house stopped working. Part of the roof had been blown off (only a plastic cover, thankfully nothing more serious) which exposed the cable and allowed things to get a little damp.

On closer inspection the 3 far pins in the connector had corroded as seen below, click any picture below to see a bigger version:

I’m presuming the corrosion had been going on some time and the storm was the icing on the cake. I tried a mixture of WD40 contact cleaner followed by a strong acid based electrical cleaner and the pins had cleaned up nicely but it still wasn’t working.

I was really trying to avoid was chopping the connector off completely as after all it is over £100 worth of camera, but that happened…

As you can see from above I opted for jelly crimps (scotch locks) as these are waterproof, the alternative was either a  surface mounted punch-down box or RJ45 coupler both which would have corroded over time and eventually left me with a broken camera again.

After making sure everything was working I wrapped the jellys in a fair amount of electric tape followed by a healthy dose of vaseline.

I would have exposed more of the camera cable which would have made things look neater and given me more room to position each jelly connector but ultimately I wanted to cut as little as possible, and the fact it was now working again was a good enough excuse to leave it alone!

Colour Combinations

It came as no suprise that the camera didn’t use standard 568B colours but here is the combination I used:

Key: 568B Standard Cable / TRENDnet Cable

  • Orange WhiteOrange
  • OrangeYellow
  • Green WhiteGreen
  • BlueGrey
  • Blue WhitePurple
  • GreenBlue
  • Brown WhiteBrown
  • BrownWhite

I found the colours by refering to this guide here. I did manage to get the green and green white cables mixed up, however this hasn’t affected the camera in any way that I can tell. If it does ever cause a problem I will swap the cables around at the patch panel to avoid having to tamper any further.

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 thrdropough 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!

Update 24/03/2017 –

I can confirm the same process below works on Windows 10 Pro, the firewall had to be switched off but that was all – 79 seconds from start to finish!

  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
  • The default user/password combination is admin/admin

Encrypted AES VPN tunnel between pfSense 2.3 and Draytek 2830

For a long time now I’ve managed several VMware ESXi servers and for easy management I’ve created a local area network on each making backups, monitoring and the usual sysad tasks a breeze.

The icing on the cake is that I recently swapped from m0n0walll to pfSense and went about setting up a lan to lan VPN tunnel to my home network, so now I can access everything locally as if I was on the same network.

Home Network

My home network uses a Draytek 2830 connected to a Virgin Media Superhub. Unfortunatley the Draytek is getting on a little bit now and doesn’t have the processing power to deal with my 100mbit connection speed, so I’ve had to double NAT the network using the Superhub in router mode and then DMZ everything towards the Draytek.

This isn’t a bad thing though as all the “dumb” wireless devices (mobile phones, Roku’s, Nest thermostat, etc) connect direct to the Superhub whilst my home server and everything crucial connect via the Draytek. All in all I get 70mbit through the Draytek on average and there’s plenty of bandwidth left for the devices connected to the Superhub.

In the example below the home network subnet will be 192.168.100.x

Remote Network

The remote network is pretty simple, they are all setup the same apart from x is a different number based on the virtual host name – a pfSense machine sits at x.1 and deals with traffic to the local network.

In the example below the remote subnet will be 192.168.150.x

Important

  • Each local area network must be on a seperate subnet, otherwise things can quickly get messy and conflict!
  • Make sure you use a secure pre-shared key, anything above 32 characters will do nicely
  • The example details below are fake, replace them with your own details if you want this to work

Configuring pfSense

The guide below lists only the parts you need to change, if the option isn’t listed then leave it as is

Fairly straight forward, go to VPN > IPSec > Click Add P1

  • Enter the Remote Gateway as the WAN IP address of the Draytek (or the Superhub in my case)
  • Enter a brieft description in the Description box
  • If you are double NAT’d like me select Peer identifer as KeyID tag then enter the WAN2 address of Draytek else leave as Peer IP address
  • Enter your pre-shared key in the Pre-Shared Key box
  • Press Save

That’s your Phase 1 entry configured, now for Phase 2:

Go to VPN > IPSec > Click on Show Phase 2 Entries for Home

  • Enter Remote Network as the home network subnet – 192.168.100.0/24
  • Put a brief description in the Description box
  • Set PSF Key Group to 2
  • Press Save and then hit Apply Changes

Finally, we need to create a firewall rule to allow traffic to pass over the VPN:

  • Go to Firewall > Rules > IPSec and click Add
  • Change Protocol to any
  • Enter a brief description in the Description box
  • Press Save any hit Apply Changes

Configuring the Draytek

Now it is time to configure the Draytek – Go to VPN and Remote Access > LAN to LAN

For Common Settings:

  • Enter a Profile Name
  • Tick Enable this profile
  • Make sure Call Direction is set to Both

For Dial-Out Settings:

  • Set type of server to IPSec Tunnel
  • Enter the Remote WAN IP in the Server IP/Hostname for VPN box
  • Enter the pre-shared key set previously in the Pre-Shared Key box
  • For IPSec Security Method set it to High (ESP)AES with Authentication
  • Under Advanced set IKE phase 1 propsal to AES256_SHa1-G14 and IKE phase 2 proposal to AES256_SHA1 then press OK

For Dial-In Settings:

  • Set the Allowed Dial-In Type to IPSec Tunnel
  • Tick the box to Specify Remote VPN Gateway and enter the remote network WAN IP
  • Enter the pre-shared key set previously in the Pre-Shared Key box
  • For IPSec Security Method untick all apart from High (ESP) – AES

Under TCP/IP Netowrk Settings:

  • Set Remote Network IP as the remote network subnet – 192.168.150.0

Hit OK at the very bottom to save the profile, leave it a few seconds and it should connect. If it doesn’t connect automatically, head to the IPSec Status page in pfSense and hit Connect manually

Install EPEL Repository on CentOS 7 (x64)

The simple one line command below will enable the EPEL repository on CentOS 7

rpm -Uvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm

Once ran you will see confirmation that it has been installed successfully, that’s it!

Notes

  • You can find out more about the EPEL repository here
  • If you don’t already have a server, I’d strongly recommend starting with DigitalOcean

Icecast PHP Stats

A recent project of mine called Coop Cam uses several live video streams served by an Icecast server at different mount points which works great, but I found there was no real solution to simply display how many viewers were actually watching the live streams.

I put together a basic PHP code that reads the Icecast XML stats file and retrieves the current overall viewers (or listeners as its officially known) of all available mount points.

Code

// get the stats xml file //
$output = file_get_contents('http://admin:[email protected]:8000/admin/stats');

// explode to make the magic happen //   
$listeners = explode('',$output);
$listeners = explode('',$listeners[1]);

// output to the world //
echo "Currently <b>$listeners[0]</b> people are watching the live stream!";

Once you have amended the admin password, server name and port the code above will then connect to your server and read the /admin/stats XML file. From here it will literally pick out the content shown between the <listeners></listeners> tags and that then becomes the $listeners[0] variable, simply place this wherever you want to display the amount of current viewers.

Notes

  • This code may or may not work depending on if your hosting provider allows the file_get_contents function – In my case I use my own dedicated servers and it works without issue, if you have any problems I’m sure I can sort something for you!
  • You can show the amount of sources, file connections and so on by amending the code to reflect the correct tags – A full list of tags can be seen by visiting the youricecastservername.com:8000/admin/stats page
  • You can find a live working example of this script here or actually see it in place here

Disable Virtualmin Two-factor Authentication

Virtualmin is constantly being developed and gaining ever useful features, and for a while now has featured two-factor authentication which is great, although what happens if you get locked out of your system? As long as you have SSH or console access then you can follow the steps below to easily get back in.

Disabling two-factor authentication for a single user

  • Get root SSH or console access
  • Edit the file /etc/webmin/miniserv.users, comment out the current line for the user then create a fresh copy above it
  • Remove any mention of “totp” and the long string of characters near the end and save, for example your file should now look like the following:
...
root:x::::::::0:0:::
#root:x::::::::0:0:totp:ZZZZZZZZZZZZZZZZ:
...
  • Restart Webmin and log back in normally

Disabling two-factor authentication entirely

  • Get root SSH or console access
  • Edit the file /etc/webmin/miniserv.conf and find the line “twofactor_provider=totp” and replace with “twofactor_provider=” and save
  • Edit the /etc/webmin/miniserv.users as mentioned above
  • Restart Webmin and log back in normally

Notes

  • I’ve had success with this on Webmin 1.760 running on CentOS 7.0

Setup your own live pet webcam for free using Yawcam

I’ve been experimenting for a while with different ways to stream live to the Internet from webcams, IP cameras and capture cards for the Coop Cam project, here is a basic guide on how to setup a simple live stream using a basic webcam.

What is required?

You will need a couple of things, including:

  • A computer with a webcam
  • An Internet connection with decent upload speed
  • Router access to port forward

Software

To create the stream we will use a free piece of opensource software called Yawcam, you can download it directly from here or learn more about the software here.

Installation is pretty simple, download and launch the installer then follow the on screen instructions.

Configuration

After the installation has finished open your newly installed software, you will see a screen like below:

1

The first thing we need to do is set the stream type, to do this go to Settings > Edit Settings…

2

Under Output select Stream and change the Stream type to MJPEG and hit OK

3

Next we need to select your webcam, head to Settings > Device > Change to and select your webcam from the list

4

Finally, back on the main screen hit enable on the Stream option – we are ready to go!

5

Previewing your stream

Here is the exciting part, previewing your live stream! On the same computer open up your browser and head to http://127.0.0.1:8081/video.mjpg

If everything is configured correctly you should see your webcam displayed live.

Here is my example of Spirit our pet quail:



What next?

The next thing you need to do is configure port forwarding in your router to allow people to connect in and view  your stream. I can’t really go into specific detail as there are many different types of router with different configuration options but basically what you want to do is forward port 8081 to your computer so anyone that connects to your-public-ip:8081/video.mjpg can see your stream.

You will also want to make sure that your computer has a static IP address or DHCP reservation to make sure the local IP address doesn’t change.

If you need help with that part let me know and I’ll give you a hand.

Will my Internet connection be able to cope?

This depends entirely on your upload speed, by default Yawcam only allows 10 concurrent connections.

For added security and to take the strain off your Internet connection I can relay your stream via Coop Cam’s powerful relay servers. They are able to take the single stream from your camera and amplify it allowing hundreds of users to connect at once.

The upside to this is that you will only have one connection being uploaded to the relay server, the server then handles everything else and even hides your public IP address – If you would like to know more please get in touch.

Notes

  • If you want Yawcam to start streaming automatically when you login to your computer then head to Settings > Edit Settings… > Startup and tick Start Stream output
  • You can check that port forwarding has been setup correctly by using the NerdTools Port Scanner, if it isn’t working double check your firewall settings
  • If your Internet connection has a dynamic IP address you’ll want to look into a Dynamic DNS service
