Two questions, about a minute. Keep a tape measure handy.

Where is this lock going?
This is a door lock. For a gate, our SL-G1 has a 34 mm panel made for narrow gate uprights and fingerprint readers on both sides.
Measure from the faceplate of your existing mortise to the centre of the square spindle hole. What does it read?
60 mm backset, 85 mm centres. This is the one most Australian doors take.
45 mm backset, 85 mm centres.
If your door slides, order the 3585 hook bolt version instead — a straight bolt will not hold on a slider.
If your door slides, order the 2885 hook bolt version instead.
A straight bolt has nothing to grip on a sliding door. Measure your backset, then order the hook bolt version of that size — 2885 hook or 3585 hook.
Measure from the faceplate to the centre of the square spindle hole. The sizing guide shows it with a diagram.

Guides and installation
One mortise, 6068, so the fitting question here is thickness rather than backset. Doors under 40 mm will not take this lock — measure the door edge before you order, because many Australian entry doors are 35 mm.

The manufacturer publishes no certification for this model. Not CE, not FCC, none. That is unusual and you should know it before spending $894.99. If you need documentation for a strata building, an insurer or a commercial fit-out, talk to us first — we would rather tell you now than after it is on your door.
No weather rating. Fit it under an eave, a porch or a roof. A facial recognition module and a screen are not things you want taking direct rain.
Doors under 40 mm will not work. Most Australian entry doors are 35 mm or 40 mm — if yours is 35 mm, this is the wrong lock. Measure the door edge before ordering.
Facial recognition is convenience, not perfection. Heavy rain, harsh backlight and a full face covering will all send you to the fingerprint reader. Every face-unlock lock on the market has the same limits.
The manufacturer's listing mentions warehouses in Mexico and Brazil. That is their copy, not ours — your order ships to you in Australia. Ask us for the current lead time before ordering.
Low stock. This is a small-quantity line. Message us before ordering more than one.
Before you buy
Fitting and measurement questions in depth live in the sizing guide. How to choose between our five types is in the buying guide.
The backset does, yes — 60 mm is the Australian standard. The catch is thickness: this lock starts at 40 mm and many Australian doors are 35 mm. Measure the edge of your door before ordering.
About a second as you walk up. That is the whole appeal — you do not stop and do anything.
It reads in three dimensions rather than as a flat image, which is what defeats a photograph. As with any biometric, treat it as very good rather than infallible, and keep a code as backup.
It uses a built-in rechargeable battery and warns you well ahead. Set a reminder the first time it does.
Yes — that is what the two-way intercom is for, through the app over Wi-Fi.
The manufacturer publishes no certification for this model. If you need compliance paperwork, contact us before you order and we will tell you honestly what we can and cannot supply.
