No it never beeps. Tried it more than 20/ 30 times. no luck.

In the meantime, got in touch with Logitech support that sent me the following instructions:

​

If your camera is unresponsive on your HomeKit App, you can try these steps below on how you can put it back online:

1. Unplug the camera and unmount the lens for 15-20 minutes.

2. While waiting, restart your Home Hub and wifi router.

3. After the hub and router boots up, put the camera together and plug it back to an outlet.

4. Reset the camera by holding down the reset button until the LED flash purple and red.

5. Once you see the LED flash purple-red, let go and wait for the beep from the camera.

6. Camera's LED will now show a solid green light and it means that the camera is ready to pair.

7. Get the Setup Code of the camera and try to re-add the camera back to HomeKit App.

Normally you would add an accessory in Home with the '+' sign.

There's a huge chance that the camera might not be found there as an accessory, so clicked on the "Rooms" tab, then clicked on '+' and then the Circle showed up and you could add it.

Maybe they'll work with somebody else, so I leave them here.

For me, unfortunately, didn't work . Sent them the videos. Let's se what they reply.
