Ubiquiti UniFi G4 Doorbell

Compiled by SmartHomeWorkflow Research · UniFi · Cameras & Doorbells · ~$199 (price at time of research: $199 on Ubiquiti's own US store, read 2026-08-17. The console is the real price. UniFi Protect requires a UniFi console by Ubiquiti's own statement, so this doorbell is not a standalone product; the cheapest console we verified that runs Protect is the UniFi Cloud Gateway Max at $279 as configured, and a console without a storage disk records nothing, since Ubiquiti says a disk 'is only required to save recordings'. Realistic entry for a recording doorbell is roughly $199 plus $279 plus storage. Never treated as a live price.)

⚠ Similar names, different products: ⚠ Ubiquiti sells at least three doorbells and the names are one word apart: this 'G4 Doorbell' (UVC-G4-DoorBell, $199), the 'G4 Doorbell Pro' — a different, higher-tier product Ubiquiti describes as having an enhanced package-detection camera and an integrated display — and a 'Doorbell Lite' (UVC-Doorbell-Lite) below both. There is also a 'G4 Doorbell Pro PoE Kit', which is the Pro bundled with its power hardware rather than a fourth model. ⚠ And note the power difference this catalogue cares about: unlike Ubiquiti's PoE cameras, THIS doorbell runs on ordinary doorbell-transformer power and joins by WiFi.

Compatibility

? Inconclusive means we researched that ecosystem and the evidence doesn’t settle it — the catch says why, and the sources are listed below. It is a statement about the available evidence, never a verdict on the product. A Setup Check researches your exact setup where the official sources don’t answer.

Protocols: WIFI · BLUETOOTH^[1]

Needs before it works: Yes, and this is what separates a UniFi doorbell from every other doorbell here. Ubiquiti's own requirement for UniFi Protect is 'A UniFi Console running Protect'; there is no app-only mode and no cloud account that substitutes, so without a console this hardware does nothing. The cheapest console we verified that runs Protect is the Cloud Gateway Max at $279 as configured, plus a storage disk if you want recordings kept. Unlike Ubiquiti's other cameras, this doorbell does not need a network switch that powers it: it runs on ordinary doorbell-transformer power at 16 to 24 volts AC and joins the network over Wi-Fi.^[3]

What it can do^[5]

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[3]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

⭐ No subscription and no licensing, stated by Ubiquiti in the negative: 'Absolutely not. Our goal is to provide you with a feature-rich security solution without any hidden or recurring fees', and 'Run 4 or 4,000 cameras - licensing is still $0.' On a shelf where the dominant business model is $5–20/month for recordings and person alerts, that is the whole argument for buying into this system — recordings live on hardware you own, and the detection runs locally. The cost is front-loaded into the console rather than spread across a plan.

Maintenance reality

• Works without the internet: Yes — the core function runs on the device or your home network. A vendor cloud may still be involved in remote access.^[8]
• Nothing to charge; it runs on the doorbell circuit at 16 to 24 volts AC, the same transformer feed the wired Ring and ecobee doorbells need. Two limits before mounting it: weatherproofing is splash-rated (IPX4) rather than the sealed ratings seen elsewhere here, and the operating range is 14 to 104 °F, noticeably narrower than Ubiquiti's own G6 Pro Bullet, so a genuinely cold porch is worth checking against that floor. Built-in microphone and speaker; flat and 20° wedge mounts in the box. Ubiquiti states the product is NDAA compliant.

Security updates^[7]

UniFi publishes no security-update support date for this model. That is a gap in what the manufacturer has published, not evidence either way — some makers declare a support period and some say nothing at all.

ASSESSED AND FOUND ABSENT, not unchecked (2026-08-20). Ubiquiti publishes an active security programme and no support period. What exists: a live advisory stream at ui.com/security-updates, running to Security Advisory Bulletin 066 at the time of reading, covering Cloud Gateways/CloudKeys, Protect and Network. What does not exist anywhere we could reach: any statement of how long a product receives security updates. Ubiquiti's own Vintage and Legacy page defines the two end-states in words — Vintage products "will continue to receive critical bug fixes and security updates", Legacy products "have stopped receiving updates" — but attaches NO duration, NO date, and does not list this product in either state. The practical position for a buyer: this vendor patches visibly and promises nothing in writing, so there is no date to hold them to.

The catch

Two things to weigh. First the system cost: a UniFi console is required, not optional, so a recording doorbell realistically means $199 plus about $279 for a Cloud Gateway Max plus storage, and Ubiquiti says plainly that without a disk the console keeps nothing. Second the generation gap: this is a 2-megapixel doorbell in a line whose current cameras are 8 megapixels, so it trails the 2K and 4K doorbells elsewhere here, and its splash rating and 14 °F floor are the least weather-hardened numbers in this group. What you buy for that is the absence of a bill: no subscription, no licensing, detection that runs on your own hardware, and recordings you own.

Who it's for

A household already committed to UniFi — one that owns or is buying a Protect console anyway — and wants the doorbell to live in the same system as the cameras, with no monthly fee and footage on its own hardware. Home Assistant homes get the strongest path here. If you want the sharpest doorbell image on this shelf, or a doorbell that works on its own out of the box, this is the wrong product: the resolution trails and the console is mandatory.

The integration's Event Entities list names a "Doorbell Ring Event". The same page states which cameras have Smart Detections: "All 'AI' series cameras … All 'G4' series cameras. This includes the G4 Doorbell, G4 Bullet, G4 Pro and G4 Instant. G3 Series cameras do not have Smart detections."
