overlook

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.

This project was forked from http://github.com/fvdm/nodejs-foscam

Usage

The installation and loading are simple with NPM.

npm install overlook

var Overlook = require('overlook');
var cam = Overlook();

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 );
  
  });
  
});

Or directly from Github

git clone https://github.com/noahpeters/overlook.git

var Overlook = require('overlook');
var cam = Overlook();

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.

setting	description	default
host	IP-address or hostname	192.168.1.239
port	port number	81
user	username	admin
pass	password	[empty]

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.

• command - The command to execute. This can be a string (see below) or number.

Commands

command	api id	description
up	0	start moving upwards
stop up	1	stop moving upwards
down	2	start moving downwards
stop down	3	stop moving downwards
left	4	start moving left
stop left	5	stop moving left
right	6	start moving right
stop right	7	stop moving right
center	25	move to center
vertical patrol	26	start moving vertical (y-axis)
stop vertical patrol	27	stop moving vertical (y-axis)
horizontal patrol	28	start moving horizontal (x-axis)
stop horizontal patrol	29	stop moving horizontal (x-axis)
io output high	94	iR on (some cameras)
io output low	95	iR off (some cameras)

cam.control.decoder( 'horizontal patrol', function() {
	console.log( 'Camera moving left-right' )
});

control.camera

( name, value, [callback] )

Change a camera (sensor) setting.

• name - the parameter name or id.
• value - its replacement value.

Parameters

name	id	values
brightness	1	0-255
contrast	2	0-6
resolution	0	value (aliases) id 320, 320x240, 320*240 8 640, 640x480, 640*480 32
mode	3	value (aliases) id 50, 50hz, 50 hz 0 60, 60hz, 60 hz 1 outdoor, outside 2
flipmirror	5	value (aliases) id default 0 flip 1 mirror 2 flipmirror, flip+mirror 3

cam.control.camera( 'resolution', 640, function() {
	console.log( 'Resolution changed to 640x480' );
});

System

( [callback ] )

Reboot the device

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

restore_factory

( [callback ] )

});

talk

( propsObject )
