Generic Camera Device using local connection (new version now available)

DjAnu · March 8, 2016, 1:17am

Hey Can you please share your code ? I have 2 Hikvision cameras that I believe has image size issue. I had been using them with swanny’s code - Synology Diskstation & Cameras - #229 by Bevanm8. Which works great for notification but I am not able to see any images on ST…Tx.

drewross · March 8, 2016, 10:00am

I have a foscam that did that. I changed the internal ip to a external ip and it worked fine.

adamrhoades · March 15, 2016, 2:20pm

Hi there, I’m also trying to add multiple cameras from the same IP, got one working great, but suspect I’m having the same issue as you, would you mind explaining your modification to a random UUID please?

Fuzzyligic · March 15, 2016, 5:00pm

@adamrhoades unfortunately i am no longer using this solution for my web cam needs with ST as it was far too buggy. all i am doing now is managing this and motion detection into smartthings as a contact sensor only using a scripts on my zoneminder box. stupidly this was a modification i did on the fly and didn’t upload to my github so i dont actually have a copy any more.

the basic crux of what i did was on the function that took the picture just before the pic was taken i set the Network ID with the correct hex IP:Port combination and i just added a step to update the Network ID of the device with a randomly generate GUID after the picture was taken so the next time another camera was used to take a pic it didn’t complain about a conflict with the Network ID, worked great until two were triggered at the same time

@pstuart - I just wanted to thank you because I simply could not have done any of the few projects I’m linking below to show you how and where your work evolved. Here’s is one notion that feel compelled to share. I’m now changing device ID to random number at end of execution so multiple devices can point to the same internal IP. This has been really useful especially when I want to point to the single Raspberry Pi but run completely different Device Handler logic. Here’s the line of code I use and it’s done at the end of the parse() function right before doing any returns.

device.deviceNetworkId = "ID_WILL_BE_CHANGED_AT_RUNTIME_" + (Math.abs(new Random().nextInt()) % 99999 + 1)

Here’s a list of my projects of mine that borrow a LOT of your contributions Thanks again, not only for figuring this out but sharing it with us. FYI, lots of folks fail above and have corrupt images. Your description of the issue is more than clear and I made sure to open a support case to give them a piece of my mind. The hubAction/S3 integration breaks at about the 40KB mark.

Raspberry Pi with PHP (or Arduino/ESP8266/NodeMCU) to GPIO to Relay to Gate/Garage Trigger Community Created Device Types

Hi all, I’m pretty excited to be able to bring this project. It ties together and old Raspberry Pi running latest version of Raspbian with HTTPD and a PHP script. The PHP code runs the gpio command in order to trigger pin 4 of the RPi for a second then turns it off. This triggers a simple 5v relay which in-turn shorts out my gate. The obvious difference of what I’m sharing here is the fact that I wrote a SmartThings Device Handler which uses a “hubaction” which means it can be triggered from a WAN connection w/o having to put your device out on the web with a public IP. The hub performs a local action on a local IP. The project is essentially a generic HTTP Device Handler for SmartThings. The goal was to keep it as small/simple as possible. So it consists only of a single PHP script and …

SmartGPIO - Raspberry Pi with PHP Returns GPIO Pin Status to ST Image Tile Community Created Device Types

Hi all, This project consists of a Raspberry Pi running Raspbian OS. It runs HTTPD with index.php as the source. The PHP has many functions but this device driver is specifically to see the GPIO status of all pins in a picture format. Here’s a related topic which contains the PHP file needed. I didn’t want to keep a copy in two places so pick up index.php from this post: [https://community.smartthings.com/t/raspberry-pi-to-php-to-gpio-to-relay-to-gate-garage-trigger/43335] Use the TEST button first to make sure that you install a required graphic component for PHP called php5-gd. Once my app senses that this component exists, it will populate the image tile. Otherwise the TAKE button will not work and not return an image as expected. SOURCE CODE: Enjoy! [image][image]

All the best!

@adamrhoades see my post just above. Should answer your question.

blebson · April 11, 2016, 6:44am

That’s a great idea for the Device ID, though it would obviously only work if something was passed back to the parse method (which it generally does). I’m going to give it a shot in my new DCS-5222L devicetype if you don’t mind

meavydev · April 11, 2016, 11:12am

I have been trying to get the generic camera code working with my ComPro IP90s.

The camera returns JPG stills in response to HTTP Gets with basic authentication:

HTTP/1.0 200 OK
Connection: close
Server: MJPG-Streamer/0.2
Cache-Control: no-store, no-cache, must-revalidate, pre-check=0, post-check=0, max-age=0
Pragma: no-cache
Expires: Mon, 3 Jan 2000 12:34:56 GMT
Content-type: image/jpeg

I have tried reducing the image size down to 7KB and I still get a generic parse respone with no data.

I tried using HTTP Get and got a ClientProtocolException.

Using the hubAction with or without the putputMsgToS3 option below doesn’t seem to make any difference:
hubAction.options = [outputMsgToS3:true]
I just get a parse response that looks like:
Parsing ‘index:17, mac:001F1F8E3773, ip:C0A800D4, port:0050, requestId:c09b8f63-d199-4cdc-9b3d-94477ce595a8’

These are on the European SmartThings website, as my hub is in the UK.

Anyone got any suggestions?

JZst · April 11, 2016, 10:43pm

Considering how much code I ripped from your projects to enrich mine, I definitely don’t mind, in fact honored

JZst · April 11, 2016, 10:49pm

Looks like you’ve tried it all including reduction of size. However, the S3 call, when it works, looks like this, notice the key & bucket. I’ve never seen an image come through w/o a good key/bucket combo. My guess is the S3 implementation with ST which has always been interesting:

I’ve been trying to get this to work with a Sercomm 8221. I get nothing. It sends the request and I see “HTTP 1.1” and that’s it, any ideas?

JZst · April 17, 2016, 5:05am

Gotta provide the log if you want help. Also show a screenshot that a regular web browser shows the image URL correctly. Lastly, try flipping between GET & POST.

Latest version of code, can’t edit the top post… Nothing new, just got lost in the shuffle.

Mbhforum · April 19, 2016, 1:00am

Is this the new code you’ve been testing?

pstuart · April 19, 2016, 1:00am

Nope, old code. Just updated link cause link at top doesn’t work and can’t edit that post.

kevin · April 27, 2016, 7:05pm

Can all this be simplified if you just want to show an image via URL on a carouselTile (similar to SmartTiles.click web client)?

Richierich · April 28, 2016, 10:52pm

ok so I had two of my IP camaras working with the new generic video in minutes, but I’ve never got it to work with this device.
I have the working feed for my vivotek camera and tested it…

‘http://username:password@192.168.1.197/cgi-bin/viewer/video.jpg?resolution=640x480’

I’ve traced through the code and it appears to give a sensible log…

e9519546-9d01-47a4-8f35-3d01af29ce36 ‎23‎:‎15‎:‎28: debug Parsing ‘index:17, mac:0002D10ED0B3, ip:C0A801C5, port:0050, requestId:fb93c50b-7191-448f-b357-fadde25f6e25’

The problem seems to be in the parse and the putImageInS3 is never called.
Not sure what to expect in descriptionmap to know why the if statement is false.

Can someone give me a little steer please?

thanks

blebson · April 28, 2016, 10:53pm

Does that URL return a single JPEG file (still image)?

Richierich · April 28, 2016, 11:48pm

Yep still image
And reading back through the threads is similar problem to #348 meavydev

gorgas99 · May 3, 2016, 2:26pm

My Sercom 8021 was working for MONTHS after Patrick helped me, but now it’s broken again. The last change was a ST hub update.

I look in the log and what do I find ? Every time I try and take a picture the ST hub shows a disconnect !

“HUB hub has disconnected hub has disconnected hub has disconnected false”

I can reproduce it consistently. I have the same setup in another house and it’s working OK at that other house.

Inside the house the cameras are working fine.

Any ideas ? Last time the issue was my DSL MTU was wrong. If it SOMEHOW got chagned back I can’t see that causeing the hub to show a disconnect in the log when I take a pic. Or could it ? I’m not at that house so I can’t check the DSL setup.

@pstuart Should I try and update your generic camera device and see if that helps ? I’m running older code ( if it an’t broke, don’t fix it) : Generic Camera Device v1.0.07102014

I opened a ST support ticket and will post any meaningful repy.

THANKS !
