NodeJS Module: node-dahua-api

sure, the API being: /cgi-bin/configManager.cgi?action=setConfig&VideoWidget[0].CustomTitle[1].Text=

I'll add this function to this project in the next version.

Thank you! This can be very interesting to play with. Do you also know if it is possible to enable/disable a certain custom text-overlay by API?
I never knew these Dahua cams are so scriptable...

On a side-note: I seem to get less to none garbled snapshots after playing the the snapshot settings in the camera (I lowered the quality and set interval on 1 sec).

I finally got to nodejs on my ubuntu 16.04 system (I have been on a longish vacation). I have installed nodejs 4.2.6, npm, pm2 and node-dahua-api (last two globally). Runing "npm list -g --depth=0" gives:
/usr/local/lib
node-dahua-api@1.0.2
pm2@1.1.3

When I try to run "sudo node dahua.js", I get the following:
module.js:328
throw err;
^

Error: Cannot find module 'node-dahua-api'

So what am I doing wrong here?
Thanks.

With the last firmware of dahua ip Cam (09/10/2016) Dahua Node Api cant connect to the cam, i think could be by autenthication method.

ipcc for domoticz cant connect to the cam at last firmware.

With the earlier firmware can connect.

In the new firmware, dahua uses digest autenthication, Can you implementing?

Thanks!!!!

Hello - I am having some issues trying to get this working.
Camera: Dahua IPC-HFW4300S

Here is the error message that i am getting when i set trace to true:
ReferenceError: options is not defined
at handleConnection (/Users/Desktop/68/node_modules/node-dahua-api/dahua.js:176:43)
at Socket.<anonymous> (/Users/Desktop/68/node_modules/node-dahua-api/dahua.js:35:10)

at emitNone (events.js:91:20)
at Socket.emit (events.js:185:7)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1077:10)

When i have the trace set to false it connects but none of the triggers are firing. I am using the example that you have provided on github.

When i set the options in the Dahua.js file this is the message that i am receiving:
Connected to 10.3.3.201:80

Any ideas on what I am doing wrong? Any insight would be much appreciated!!
 
it looks like your config might be malformed; it says options is not defined.

@uronito, what camera and firmware are you having trouble with?
 
Hi @nayr ,

My cam is Dahua DH-SD29204T-GN-W,

with the firmware 2.400.0000.16.R.T4.484.9A.NR, build : 2016-05-17, dahua-node.js work correctly,

but with the last fimware DH_SD-Mao-Themis_Eng_P_Stream3_IVS_V2.422.0000.3.R.20161009 , dahua-nodejs connect but close connection at 1 second, response is 401.

i think that dahua changes method authentication.

i have had downgrade for dahua-nodejs works again.

Thanks!!!!!

Regards.
 
what would that accomplish? the numerical ID should be adaquate.
 
of the preset
 
Sorry, I don't understand you. I would like to get a list of user defined presets with corresponding IDs and captions. Is this possible?
 
you can dahua.ptzPreset(10), and it'll go to preset #10.. if that preset is not setup on the camera, then it wont do anything... I know of no way to extract any configurations you have for that preset.. just to use it.

If you can give me a valid use case; I may look into it.. but right now, I see absolutely no use in such a function..
 
Very simple... For instance, you want to make some custom UI where you want to display presets and allow user to click preset to go to it.
 
most Camera UI's give you a numeical input, or selection box where you select 1-50 or something.. Not even Dahua's own apps do what your wanting so dont hold your breath.

You could always have them give names in your app, they dont nessicarly have to share names with the camera presets.. those preset names are only used if you enabled the status OSD text... like add preset, #1 - Yard, save.. now you have a button that says Yard and calls preset #1

If your wanting to make a camera app like you describe, you should look into using ONVIF so its not specific only to Dahua brand.. this module wont work with non-dahuas.. It was designed for those wanting to do some automation w/Dahuas and less for making a full featured Dahua client.. theres a ton of API calls I have not implemented, I only started with those most needed w/automation scripts.

It's sounds silly for me to expect that user will remember dozens of presets by numbers. And I were pretty sure that it's nor problem at all - as long as I can see the list via camera's web interface. If I can receive the list to show on web interface, so why I can't receive it via API?
