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');
});

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
