Hello @gluedots, thank you for your interest in our work!

If this is a bug report, please provide screenshots and minimum viable code to reproduce your issue, otherwise we can not help you.

thanks @gluedots; to confirm, which version of the firmware is your camera on now?

[gluedots]

It's a v2 on 4.9.7.798

I believe this is due to DTLS being enabled on the newer firmware to patch the recent security vulnerability in tutk.

You can see which of the cameras have DTLS enabled with:

import wyzecam
auth_info = wyzecam.login(email,password)
for device in wyzecam.api.get_homepage_object_list(auth_info)["device_list"]:
    print(f"{device['nickname']:15} v.{device['firmware_ver']} DTLS: {device['device_params']['dtls']}")

[mrlt8]

This should generate the authkey, but I think you'd still need tutk 3.1.10+ to make the connection...

key = self.camera.enr + self.camera.mac.upper()
hash = hashlib.sha256(key.encode())
bArr = bytearray(hash.digest())[0:6]
authKey = base64.standard_b64encode(bArr).decode().replace('+', 'Z').replace('/', '9').replace('=', 'A').encode()

Where can you get tutk 3.1.10+ .dll and .so files?

Did anyone solve this?

[mrlt8]

Yes, see my post above.

Here's a working example.

You'll need to supply your own libIOTCAPIs_ALL v3.1.10 or higher.

Just want to confirm if libIOTCAPIs_ALL v3.1.10+ is freely available or if it requires a paid license or maybe shady browsing.
Where can we get this?
@mrlt8 How did you get your copy?

[mrlt8]

Depending on your target platform, there are a few libraries floating around.

I believe you will need an SDK license key for v4+.

You could always contact tutk directly, but you will need to fill out a couple of forms and sign some NDAs.

Can someone share a copy of the library?
I have searched quite a bit and unable to connect to the latest firmware update. I see DTLS:1 in the device. Any idea on how to solve it?
