Smart Lock - Sliding Glass Lock (G9S)

A glass door smart lock for the one door most locks cannot go on: frameless glass. Shopfronts, showrooms, meeting rooms and reception areas, where the door is a sheet of toughened glass with no frame to screw into. It clamps the glass instead.

Five ways in: fingerprint, code, IC card, the Tuya app and a mechanical key. Wi-Fi is built in, so there is no gateway to buy. For a business that matters more than it does at home: staff get their own fingerprints, a contractor gets a one-time password that dies after a single use, and the app keeps the record of who opened up in the morning.

It holds 300 users, nine of them administrators, and has a colour screen, a doorbell and spoken prompts. Fingerprints read at any angle and match in 0.6 seconds.

The glass must be 8 to 12 mm thick. It suits a single glass door or a pair. The door handle is not included, so if you are fitting this to a bare glass door, budget for handles too. Grey anodised aluminium with a black glass front.

The door most locks cannot go on

A glass door smart lock clamps the glass rather than screwing into a frame, which is what makes it fit a frameless toughened glass door. Shopfronts, showrooms, meeting rooms and reception areas are all built that way, and an ordinary mortise or rim lock has nothing to fix to.

The glass has to be 8 to 12 mm thick, and it suits a single glass door or a pair of them.

Why a business wants a glass door smart lock

Five ways in: fingerprint, code, IC card, the Tuya app and a mechanical key, with Wi-Fi built in so there is no gateway to buy. For a business that matters more than it does at home. Staff get their own fingerprints, a contractor gets a one-time password that dies after a single use, and the app keeps the record of who opened up in the morning.

It holds 300 users, 291 of them standard and nine administrators, which covers a shop or an office without running out of slots.

Screen, doorbell and speed

There is a colour screen, a built-in doorbell and spoken prompts, so nobody is guessing at what the lock is doing. The semiconductor sensor reads at any angle, matches a print in 0.6 seconds and reacts in under 0.1 seconds. Published rates are a false rejection rate at or below 0.1% and a false acceptance rate at or below 0.001%. The keypad is a 12-key touchscreen taking 6 to 8 digit codes.

Two things to settle first

The door handle is not included. If you are fitting this to a bare glass door, budget for handles as well, and tell us and we will quote them with it.

The body is grey anodised aluminium with a black glass front, 190 x 70 x 39 mm. Four AA alkaline cells power it, with a 5 V USB Type-C port for emergency power and a low voltage warning at 4.6 V. It works from -25 to 60 degrees C.

Glass thickness, and the handles

Two things before you order. Your glass has to be 8 to 12 mm, which covers most shopfront and partition glazing but not all of it. And the door handle is not in the box, so if the door is currently bare, budget for handles and we will quote them alongside.

For a shop this earns its keep on the access log more than the lock: staff prints, a one-time code for a contractor, and a record of who opened up. Other locks: smart locks. App: tuya.com.
