lib32100

Library implementing port 32100 UDP Cloud protocol used by many P2P cameras. You can find a description of the protocol in the wiki

News

• Check my new Wireshark dissector to analyze the protocol
• Warning: since the commands directed to cams turnedo out to be vendor-specific, they will be deprecated and afterwards removed in next major release, keeping just the transport protocol in core lib and leaving higher-level payload interpretation to specific client implementation.

Install

npm install --save lib32100

Usage

Require the Library

const lib32100 = require('lib32100')

Istantiate a client

const client = lib32100.client()

Note that each client can handle one device (camera) and multiple cloud servers.

Add servers

client.addServer({host: "myserver.example.com", port: 32100})

Set the device UID

client.setUid('PROD123456ABCDE')

Add listeners

client.on('stun', (e) => console.log(JSON.stringify(e)))
client.on('lookup', (e) => console.log(JSON.stringify(e)))

Send commands to the Cloud servers

client.sendSTUNRequest()
client.lookupUid()

Add camera address

client.addCamAddress({host: "192.168.0.100", port: 10088})

Set camera credentials

client.setCamCredentials({user: 'admin', pass: 'password'})

Open direct camera session

client.openDirectCamSession({host: "192.168.0.100", port: 10088})

Check credentials

client.checkCredentials()

Get snapshot

client.getSnapshot()

Send custom GET request

client.sendGet('/custom_url.cgi?myparam=hello')

Send multiple GET requests

client.sendMultipleGet(['/custom_url1.cgi', '/custom_url2.cgi', '/custom_url3.cgi'])

Get live video stream

client.getVideoStream()

Get live audio stream

client.getAudioStream()

Stop video stream

client.stopVideoStream()

Stop audio stream

client.stopAudioStream()

Get various information

client.getParams()
client.getCameraParams()
client.getFactoryParam()
client.getStatus()
client.cameraControl()
client.getMisc()
client.login()
client.getRtsp()
client.getOnvif()
client.getRecord()
client.wifiScan()
client.getWifiScanResult()

Move in directions in steps

client.stepDown()
client.stepLeft()
client.stepRight()
client.stepUp()

Move in directions

client.moveDown()
client.moveLeft()
client.moveRight()
client.moveUp()
client.stopMove()

Close session

client.closeCamSession()

Events

You can listen on the following events:

stun (server response)
lookup (server response)
lookupACK (server response)
unknownMsg (any message not yet parsable by the library)
pingpong (camera ping or pong)
close (camera closed session)
confirmed (camera comfirmed ID i.e. session opened)
ack (camera acked a message)
http (an http response)
audio (live audio data)
video (live video data)
complete (a complete http response)
lostConnection (the connection was lost)

TODO

• improve documentation
• improve reliability (add various checks / validations)
• parse camera id in response
• automate connection (from uid lookup to selecting the address)
• add other connection methods (relays, ...)
• add methods to retrieve / set parameters / reboot / etc
• parse responses
• add more details in events
• verify send acks and correct sequence numbers
• add callbacks / promises
• authenticated http requests
• send audio to the camera
• implement server
• emulate camera
• translate stream to RTP

DISCLAIMER

This implementation is not based on official specs but purely on reverse engineering of the protocol. I cannot guarantee it will work on every device.
