Documentation

foscam

Remote control, view and config a Foscam/Tenvis IP camera.

All included methods are based on Foscam's (fragmented) API documentation. Some features may not be supported by non-pan/tilt, older cameras or old firmware. So make sure you keep a backup of your camera settings, just in case.

Usage

var cam = require ('foscam');

cam.setup ({
  host: 'mycamera.lan',
  port: 81,
  user: 'admin',
  pass: ''
});

// start rotating left
cam.control.decoder ('left', function () {

  // stop rotation
  cam.control.decoder ('stop left', function () {

    // take a picture and store it on your computer
    cam.snapshot ('/path/to/save.jpg', console.log);

  });
});

Installation

Stable: npm install foscam

Develop: npm install fvdm/nodejs-foscam#develop

Methods

Every method takes a callback function as last parameter. The callbacks are the only way to procedural scripting.

NOTE: Some methods require a certain access-level, i.e. admins can do everything, but a visitor can only view.

Basic

setup

( properties, [callback] )

In order to connect to the camera you first need to provide its access details. You can either do this by setting the properties below directly in cam.settings, but better is to use cam.setup(). When the callback function is provided, setup() will attempt to connect to the camera and retrieve its status, returned as object to the callback. When it fails the callback gets false.

name type default description
host string 192.168.1.239 Camera IP or hostname
port number 81 Camera port number
user string admin Username
pass string Password
cam.setup (
  {
    host: 'mycamera.lan',
    port: 81,
    user: 'admin'
    pass: ''
  },
  function (status) {
    if (!status) {
      console.error ('ERROR: can\'t connect');    } else {
      console.log (status);
    }
  }
);

status

( callback )

Permission: everyone

Get basic details from the camera.

cam.status (console.log);
{ id: '001A11A00A0B',
  sys_ver: '0.37.2.36',
  app_ver: '3.2.2.18',
  alias: 'Cam1',
  now: '1343304558',
  tz: '-3600',
  alarm_status: '0',
  ddns_status: '0',
  ddns_host: '',
  oray_type: '0',
  upnp_status: '0',
  p2p_status: '0',
  p2p_local_port: '23505',
  msn_status: '0',
  alarm_status_str: 'no alarm',
  ddns_status_str: 'No Action',
  upnp_status_str: 'No Action' }

camera_params

( callback )

Permission: visitor

Get camera sensor settings.

cam.camera_params (console.log);
{ resolution: 32,
  brightness: 96,
  contrast: 4,
  mode: 1,
  flip: 0,
  fps: 0 }

Camera

snapshot

( [filename], callback )

Take a snapshot. Either receive the binary JPEG in the callback or specify a filename to store it on your computer.

When a filename is provided the callback will return either the filename on success or false on faillure.

// custom processing
cam.snapshot (function (jpeg) {
  // add binary processing here
});

// store locally
cam.snapshot ('./my_view.jpg', console.log);

preset.set

( id, [cb] )

Save current camera position in preset #id. You can set presets 1 to 16.

cam.preset.set (3, console.log);

preset.go

( id, [cb] )

Move camera to the position as stored in preset #id. You can use presets 1 to 16.

cam.preset.go (3, console.log);

control.decoder

( command, [callback] )

Control camera movement, like pan and tilt.

The command to execute can be a string or number.

command description
up start moving up
stop up stop moving up
down start moving down
stop down stop moving down
left start moving left
stop left stop moving left
right start moving right
stop right stop moving right
center move to center
vertical patrol start moving y-axis
stop vertical patrol stop moving y-axis
horizontal patrol start moving x-axis
stop horizontal patrol stop moving x-axis
io output high iR on (some cameras)
io output low iR off (some camera)
cam.control.decoder ('horizontal patrol', function () {
  console.log ('Camera moving left-right');
});

control.camera

( name, value, [callback] )

Change a camera (sensor) setting.

name value
resolution 240 (320x240) or 480 (640x480)
brightness 0 to 255
contrast 0 to 6
mode 50 Hz, 60 Hz or outdoor
flipmirror default, flip, mirror or flipmirror
cam.control.camera ('resolution', 640, function () {
  console.log ('Resolution changed to 640x480');
});

System

reboot

( [callback ] )

Reboot the device

cam.reboot (function () {
  console.log ('Rebooting camera');
});

restore_factory

( [callback ] )

Reset all settings back to their factory values.

cam.restore_factory (function () {
  console.log ('Resetting camera settings to factory defaults');
});

talk

( propsObject )

Directly communicate with the device.

property type required value
path string yes i.e. get_params.cgi
fields object no i.e. {ntp_enable: 1, ntp_svr: 'ntp.xs4all.nl'}
encoding string no binary or utf8 (default)
callback function yes i.e. function (err, res)
cam.talk (
  {
    path: 'set_datetime.cgi',
    fields: {
      ntp_enable: 1,
      ntp_svr: 'ntp.xs4all.nl',
      tz: -3600
    }
  },
  function (response) {
    console.log (response);
  }
);
