Q&A

What is the difference between the S6 Max and the V5 Vision?

Both combine biometric unlocking with a video doorbell, but the S6 Max leads with finger-vein and face recognition together, while the V5 Vision leads with hands-free three-dimensional face recognition and adds Apple Home Key and HomeKit support. The S6 Max starts at $1,050 CAD; the V5 Vision starts at $1,150 CAD.

Can the S6 Max show me a package left at my door?

Yes. The dual-camera system covers both the visitor at eye level and the ground in front of the door, viewable on the 4.7-inch indoor display or remotely through the app, so deliveries and missed drop-offs are visible without opening the door.

Does the S6 Max store video footage in the cloud?

Video clips get 3 days of free rolling cloud storage. Biometric data, including your face and vein templates, is a separate system: it is encrypted and stored locally on the lock itself, never uploaded to the cloud.
