This is an almost complete visca-over-ip implementation that can be used to control pan/tilt/zoom cameras from various manufacturers. I created this because the other options were bloated, didn't function, were complex or lacked documentation. This project aims to be as simple as possible while still complying to all visca protocol specifications.
This project is heavily inspired by Utoputopiantools visca implementation. A part of the command handling was originally created by utopian and restructured/rewrited by me. Thanks!
The inquire commands and add complete documentation are in the pipeline but I'm just really busy. Feel free to create a pull request!
This implementation consists of two classes, a ViscaCamera class and a ViscaCommand class. The ViscaCamera class does the communication with the camera and handles the packets/commands, and ViscaCommand is a wrapper around a visca command on which you can tie events.
const { ViscaCamera, ViscaCommand } = require('visca-over-ip');
var camera = new ViscaCamera('10.99.10.104', 5672);
var command = ViscaCommand.cameraPanTiltHome()
command.on('ack', () => {
console.log('Command acknowledged')
})
camera.on('connected', () => {
console.log('Camera connected')
camera.sendCommand(command)
})
