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
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 );
});
});
git clone https://github.com/noahpeters/overlook.git
var Overlook = require('overlook');
var cam = Overlook();
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.
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 );
}
}
);

Get basic details from the camera.
cam.status( console.log );

Get camera sensor settings.
cam.camera_params( console.log );
{ resolution: 32,
brightness: 96,
contrast: 4,
mode: 1,
flip: 0,
fps: 0 }
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 );
Save current camera position in preset #id
. You can set presets 1 to 16.
cam.preset.set( 3, console.log );
Move camera to the position as stored in preset #id
. You can use presets 1 to 16.
cam.preset.go( 3, console.log );
Control camera movement, like pan and tilt.
- command - The command to execute. This can be a string (see below) or number.
command | api id | description |

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' )
});
