UniFi G6 Dome vs G6 Pro Dome: Worth $220?

Both cameras exist for the same kind of position: somewhere a camera can be reached, struck, or pushed aside. The G6 Dome arrived in June 2025 as the vandal-rated version of the $199 cameras. The G6 Pro Dome followed in October 2025, putting the Pro tier's larger sensor and zoom lens behind the same kind of cover.

The vandal rating is a tie, so the $220 is a question about the picture. Most dome positions are close-range: a corridor, a lobby, a doorway. A few are not, and those are where the Pro belongs. How to choose a UniFi Protect camera maps all ten G6 cameras this site tracks, and the Security Cameras hub lists every model.

With the same eight megapixels on each, a bright scene a few meters away will look much the same from either camera. The larger sensor pays off when light is short, because each pixel has more area to gather it. The zoom lens pays off when the subject is far, because it puts the full frame on the area that matters instead of cropping a wide one.

Dome positions that need both are specific and recognizable. A car-park ceiling camera watching an entry barrier thirty meters off. A school entrance camera that must show a face at the gate, not just a figure at the door. A platform camera looking down a long, dim concourse. In a four-meter corridor, none of this applies and the fixed 109.9° lens is the better fit, since it sees the whole width.

The extra ten meters matter mainly with the lens zoomed in, where the Pro can frame a subject the G6 Dome's illuminators would not light. Indoors, where many domes are fitted, both ratings exceed the length of the room and the point is moot.

Any dome has one night-time quirk: the curved cover in front of the lens can pick up the camera's own IR if it is dirty or scratched, which shows as haze. Keeping the cover clean matters more to night image quality on either camera than the difference between the two ratings. These are manufacturer IR figures, not identification distances.

Power is the practical gate. A corridor of G6 Domes at 9.25 W each runs happily from an entry-level PoE switch; the same run of Pro Domes needs PoE+ ports and sixty percent more budget. PoE budget planning totals a run, and how to choose a UniFi switch breaks down port counts, PoE standards, and budgets across the four switches this site tracks.

The microSD slot gives the Pro somewhere to keep recording if its link to the recorder drops; the G6 Dome has no fallback and relies entirely on a gateway or NVR running Protect. Weight matters for the flush mount both bodies accept: 1.2 kg is a lot to hang from a suspended-ceiling tile without support above it. The GbE port is a convenience, since a 4K stream fits well inside 100 Mbps.

The shared limits are worth knowing before choosing either. Neither dome is rated below -20 °C, so an exposed position in a hard-winter climate points to a turret instead. The G6 Pro Turret keeps the Pro optics and reaches -30 °C, a trade set out in G6 Pro Turret vs G6 Pro Dome. And neither dome's spec sheet lists a speaker, so a camera that must talk to visitors is a different body.

Both run the same detections: person, vehicle, and animal, with face and license-plate recognition. If the choice is really between a dome and a cheaper non-vandal body, G6 Dome vs G6 Turret covers that decision at the lower tier.

The vandal rating is settled, so ask how far away the subject is and how dark the scene gets. Close and lit is the G6 Dome. Far or dim is the Pro.

Buy the G6 Pro Dome if:

• The subject is distant. An entry barrier, a gate, or the far end of a concourse needs the 45.5° tele view.
• The scene is poorly lit. The 1/1.2" sensor and ƒ/1.5 lens are built for it.
• Recording must survive a link failure. Only the Pro has a microSD slot.
• One camera carries the identification. Spend on the view that has to stand up later.

Buy the G6 Dome if:

• The view is a room, corridor, or doorway. A fixed 109.9° lens covers the width, and zoom would go unused.
• You are fitting a run of them. $220 saved per position funds more positions.
• Your switch supplies plain PoE. 9.25 W suits ports that fall short of the Pro's PoE+ requirement.
• The mount is a ceiling tile. 820 g is kinder to it than 1.2 kg.
