Network scan IP Camera (Dahua)

Hi,
I am building an app for Dahua camera's. It seems to work all but I would like to implement the list_devices function so that only Dahua Camera's will be shown. This means I need to scan the network somehow and identify what is a Dahua camera. Anyone thoughts how to do this?

From what I can infer from the code (not at all tested, just to get you going):
const ipcamera = require('node-dahua-api');const checkForDahua = async (ip) => {
const client = new ipcamera.dahua({
host : ip,
... /* other options */
});
return new Promise((resolve, reject) => {
dahua.once('error', reject);
dahua.once('connect', () => resolve(client));
});
};
class DahuaDriver extends Homey.Driver {
...
async onPairListDevices(data, callback) {
let cameras = [];
for (let i = 2; i < 255; i++) {
try {
let client = await checkForDahua('192.168.1.' + i);
cameras.push(client);
} catch(e) {
}
}
return callback(null, cameras);
}
}
Thanks. This is almost the same what I tried but this is taking relative long. So I first want to scan all the ip address an look for a manufacturer that is dahua and then do this on the limited set of ip addresses. But I am not sure how to find the manufacture (as for example you will see in Advanced IP Scanner).
Unfortunately I cannot use the api as I am on windows and they use net-keepalive which is not supported under windows.
If you need testing, just let me know.
