I am having the same problem, I am looping through several cameras.
I am calling the function in the server.js and the console.log output is changing fine with the actual ip's. But it uses the same data first time around and randomly jumps between cameras.
Is this a cache issue?
console.log('Current camera ip = ' + params.address);
var device = devices[params.address];
So I get the output in the terminal.
Current camera ip = 192.168.1.37
Current camera ip = 192.168.1.48
Current camera ip = 192.168.1.56

UPDATE.
I have changed the following and it now works but there is a major speed decrees with the init device.init().then(() Is there something wrong in the loop?
var device = devices[params.address];
device.fetchSnapshot((error, result) => {
to
var device = devices[params.address];
device.init().then(() => {
device.fetchSnapshot((error, result) => {
from node-onvif.
Okay anybody else having issue with multiple cameras can use this.
function saveSnapshot(conn, params) {
console.log('saveSnapshot server.js = ' + params.address);
var device = '';
var device = devices[params.address];
if(!device) {
var res = {'id': 'fetchSnapshot', 'error': 'The specified device is not found: ' + params.address};
conn.send(JSON.stringify(res));
return;
}
// Initialize the OnvifDevice object
device.fetchSnapshot().then(() => {
// Get the data of the snapshot
console.log('fetching the data of the snapshot...');
return device.fetchSnapshot();
}).then((res) => {
// Save the data to a file
fs.writeFileSync(__dirname + '/public/camera-public/' + Date.now() + '-' + params.address.split('.').join('') + '-snapshot.jpg', res.body, {encoding: 'binary'});
console.log('Done!');
}).catch((error) => {
console.error(error);
});
}
