About this lock
A lock and a video peephole in one outside panel. With the Kezvion camera lock you see who is at the door on your phone instead of opening it, and you unlock from wherever you are. Wi-Fi is built into the lock — it joins your home network directly, with no gateway to buy or power.
Check the backset first
This lock has a 22 mm backset, which is narrow by design. A standard hinged timber front door is usually 60 mm and this lock will not fit it. The 22 mm backset pairs with the distance between centres — 147, 160, 170, 180, 190 or 240 mm — the measurement you take on a narrow aluminium or glass-framed door. Door thickness 35–55 mm. The sizing guide shows where to measure; a photo of your door edge with a tape across it is enough for us to confirm the option.
Ways to unlock
- Fingerprint — stored on the lock.
- Keypad code — permanent, temporary or one-time.
- RFID card — for regular visitors.
- Tuya app — camera feed, access log and remote unlocking.
- Mechanical key — the override.
Good to know
- It is a video peephole: it shows and records who is at the door. It is not a security-camera system — no cloud recording plan is included and there is no continuous recording.
- No published weather rating — sheltered doors only.
- Compliance marking (CE) is stated by the manufacturer; documentation is being verified.
- Not certified for fire doors or required exit doors.

Backset CalculatorTwo questions, about a minute — find the exact mortise for your door
Two questions, about a minute. Keep a tape measure handy.
1Your door
Where is this lock going?
The gate lock suits that better
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.
2Your measurement
Measure from the faceplate of your existing mortise to the centre of the square spindle hole. What does it read?
Order the 6085 mortise
60 mm backset, 85 mm centres. This is the one most 60 mm timber doors take.
Order the 4585 mortise
45 mm backset, 85 mm centres.
Order the 3585 mortise
If your door slides, order the 3585 hook bolt version instead — a straight bolt will not hold on a slider.
Order the 2885 mortise
If your door slides, order the 2885 hook bolt version instead.
You need a hook bolt
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 the mortise, not the door
Measure from the faceplate to the centre of the square spindle hole. The sizing guide shows it with a diagram.

Guides and installation
Check the size, then follow the guide
This lock is measured in centres, not backset — the two figures in each option are the 22 mm backset and the distance between centres. That 22 mm is narrow: a standard hinged timber front door is 44 to 60 mm and will not take it. Measure before you choose.

Read this before you order
Read the backset again: 22 mm. If you have a standard hinged timber front door, its backset is 44 to 60 mm and this lock will not fit it. Order the Fingerprint & Code lever lock or the Long Handle push/pull lock instead. This is the single most likely reason someone returns this product.
No weather rating. The manufacturer publishes none. Sheltered doors and internal doors only.
The camera is a video peephole, not a security system. No cloud recording package is included and no continuous recording is claimed. Judge it as a peephole you can see from your phone.
One option is labelled “Signal” in the manufacturer's list and is not clearly documented. Message us before choosing it and we will confirm what you would receive.
CE marked according to the manufacturer (documentation being verified); no UKCA marking is claimed. Ask us before ordering if you need compliance paperwork.

Before you buy
Questions people ask about this lock
Fitting and measurement questions in depth live in the sizing guide. How to choose between our five types is in the buying guide.
Will it fit my front door?
Only if your door has a narrow stile with a 22 mm backset — typically aluminium-framed or glass. A standard timber front door (44 to 60 mm backset) needs a different lock. Measure before you order.
Do I need to buy a gateway?
No. Wi-Fi is built in, which is unusual at this price and is the main reason to choose this model.
Can I see the camera when I am not home?
Yes, through the Tuya app over your home Wi-Fi.
Does it record continuously?
No. Treat it as a peephole you can view and check from your phone.
Can it go on an exposed door?
No — there is no published weather rating. Sheltered entries only.
How do I measure the centre distance?
On your existing lock, measure from the centre of the handle spindle to the centre of the key cylinder. That number matches one of the options.
