J3 Video Doorbell Camera — 2K 2560 × 1440, AI Human Detection, No Wiring
- 2K — 2560 × 1440 — roughly twice the pixels of a 1080p doorbell, so a face at 3 m still has detail to give a police report.
- AI human detection — filters passing cars and moving foliage, so the phone only buzzes when a person is at the door.
- One unit replaces three — doorbell, camera and peephole viewer in a single housing.
- 5 m IR night vision — four 850 nm LEDs with automatic ICR switching.
- Loud indoor chime in the box — 5200 mAh battery, 1–3 months per charge, USB-C.
One Unit Replaces Three
Doorbell, camera and peephole viewer in one housing. On a door that already has a peephole, the J3 takes over the job — no second hole, no second app.
2K Video, Not 1080p
2560 × 1440 at up to 15 fps. The extra pixels are what let a distributor answer the only question that matters at the shelf: can you read a face, not just see a shape.
5 m Night Vision
Four 850 nm IR LEDs switch on automatically when the light drops, covering a driveway approach at night.
Answer the Door from the Phone
A ring opens a live call in the app. Talk to the visitor, or just watch and decide — useful for deliveries, useless for door-to-door sellers.
A Chime You Can Hear from the Back Room
The indoor chime in the box is deliberately loud; a visitor outside a closed door is not missed inside the flat.
AI Alerts That Skip the Noise
Human-shaped movement triggers an alert; a cat, a branch or a passing car does not. Fewer notifications means the ones that arrive get read.
Everyone in the Household Sees the Door
Device sharing in the app gives each family member their own login to the same doorbell — no shared password, no arguing over who has the phone.

Frequently Asked Questions
How is the J3 different from a 1080p doorbell?
Resolution. The J3 records 2560 × 1440 instead of 1920 × 1080, so faces and number plates keep detail at a distance where a 1080p frame has already turned into a smudge.
Does the AI detection need a subscription?
No. Human detection runs on the device. Cloud storage is a separate, optional service.
What is the field of view?
67° diagonal / 59° horizontal, covering a 90° scene up to 5 m — a normal doorway plus the step in front of it.
Can it be fitted to a rental door?
Yes. The mounting kit uses adhesive or two screws, so there is no wiring and no electrician.
How long does the battery last?
1–3 months of typical use, up to 3 months standby. Heavy live-view use and cold weather shorten it.
Is a chime included?
Yes — one indoor chime, in the box, on every unit.
Do you offer OEM and private label?
Yes. Logo, packaging, manual and colour from 300 units per model — send the target market and we quote.

Where the J3 fits in the range
The J3 is the value step into 2K. It keeps the no-wiring, chime-in-the-box formula of the J1 and J2 but doubles the pixel count and adds on-device human detection — the two features retail buyers actually ask about at this price band.
Sell it as the middle SKU: below it a 1080p model for price-led shelves, above it the J4 for buyers who want the battery figure printed on the front of the box.
