Shelly Presence Gen4 counts people differently on the US and EU pages
Shelly's US page says Presence Gen4 tracks up to ten people, with radar and no camera. The EU page says six people and 42 square meters. Ambient's headline is about $85.
The short version
The US page says a radar sensor with no camera, up to ten people, up to ten zones, and coverage up to 450 square feet. The EU page says up to six people and up to 42 square meters, at 69.90 euro. The Ambient's headline says up to ten people, no camera, for about $85.
Two storefronts, two ceilings
Shelly's US product page for Presence Gen4 White describes a millimeter-wave radar sensor with no camera. It says the device tracks up to ten people, supports up to ten zones, and can hold a still-presence reading. Coverage on that page runs up to 450 square feet. The same company's EU page, for a product with the same name, says up to six people and up to 42 square meters, and it lists 69.90 euro. This brief will not average those sentences into one global spec. A buyer reads the page for the plug and the currency in front of them. The Ambient's October 17 headline follows the ten-person, no-camera line and puts the price near $85. A camera that was sold as local, and still opened a stream off the device, is a different dependency.the local-camera brief.
What the US page is willing to enter
The US page aims the sensor at restrooms, bedrooms, and offices, which is a placement claim that depends on the no-camera sentence. Radios on that page are Wi-Fi, Zigbee, and Bluetooth, and the page says the sensor is Matter-certified. Still-presence is the feature that is supposed to notice a person who has stopped walking. Zones are the feature that is supposed to divide one room into several areas. None of those lines is a promise about a second region's firmware. The smart-homes desk isSmart Homes.
What the EU page is willing to enter
The EU page's six-person ceiling and 42-square-meter ceiling are the figures a European listing is willing to print. The euro price sits on that page. Treating the US ten-person line as a correction of the EU page, or the reverse, would invent a reconciliation Shelly has not published on either URL this brief used. Two listings can share a product name and still publish different limits. Privacy, for a key that stays with the holder rather than a room sensor, isthe key stays with the holder.
What The Ambient adds, and what it does not
The Ambient headline is a third account of the no-camera, ten-person framing, plus a dollar price near $85. It does not replace the EU page. It does not convert 450 square feet into 42 square meters. A headline that matches the US people-count is evidence that an outlet repeated the US listing, which is useful, and it is still one outlet. The paper is Asked directly, Why does this page refuse to merge the US and EU people counts? The US page says up to ten people. The EU page says up to six. Those are different product sentences. A reader in one market should not be handed the other market's number.Futureweb.
Matter is a certification line, not a floor plan
Matter on the US page means Shelly is willing to say the sensor is certified for that standard. It does not tell a reader how many zones a particular controller will import, or whether a still person in a bedroom will count the same way on every hub. Certification is a membership claim. The people-count and the area are separate claims, and they already disagree across Shelly's own sites. Networking, for a path rather than a room sensor, isNetworking.
A sensor without a lens is still a sensor
No camera is a narrower claim than no data leaves the house. Radar that tracks people, zones, and stillness is still a measurement of who is in a room. The US page calls that privacy-friendly for rooms where a lens is unwelcome. A reader can accept the no-lens sentence and still ask where the occupancy events go after they leave the radio. That question is not answered by the people-count. Hardware, for a board rather than this sensor, isHardware.
What this page will keep separate
The record is three pages. The US listing: radar, no camera, ten people, ten zones, 450 square feet, Wi-Fi, Zigbee, Bluetooth, Matter. The EU listing: six people, 42 square meters, 69.90 euro. The Ambient headline: about $85, ten people, no camera. Full production rumors, pet tuning, and a US street price beyond that headline are outside this page. Software, for a version string rather than a sensor listing, isSoftware.
Who the disagreement binds
A US installer who quotes ten people is quoting the US page. A European installer who quotes six is quoting the EU page. A reviewer who quotes $85 is quoting The Ambient's headline, not a Shelly invoice. The dependency is which sentence a buyer is allowed to rely on. Security, for an advisory rather than a storefront, is Asked directly, Does the US Shelly page say Presence Gen4 uses a camera? The US page describes millimeter-wave radar and says the sensor has no camera. That is the privacy claim this brief will repeat, and it will not add a recording feature the page does not list.Security.
Where the listings sit
The two Shelly URLs are the product pages. The Ambient URL is the headline account. Feature claims in this brief come from those pages. Nothing here is a teardown, a radio capture, or a promise that every unit in a carton matches the higher number. The short answer this page will stand on is this: The US page says a radar sensor with no camera, up to ten people, up to ten zones, and coverage up to 450 square feet. The EU page says up to six people and up to 42 square meters, at 69.90 euro. The Ambient's headline says up to ten people, no camera, for about $85.

Questions
Does the US Shelly page say Presence Gen4 uses a camera?
The US page describes millimeter-wave radar and says the sensor has no camera. That is the privacy claim this brief will repeat, and it will not add a recording feature the page does not list.
Why does this page refuse to merge the US and EU people counts?
The US page says up to ten people. The EU page says up to six. Those are different product sentences. A reader in one market should not be handed the other market's number.
What area does each Shelly page print?
The US page says coverage up to 450 square feet. The EU page says up to 42 square meters. This brief leaves both figures on the page that printed them.
What price does The Ambient's headline use?
The headline puts the sensor near $85 and says it tracks up to ten people without a camera. The euro price on the EU page, 69.90, is a different tag.
Which radios does the US page name?
The US page lists Wi-Fi, Zigbee, and Bluetooth, and it says the sensor is Matter-certified. The Ambient headline is the price and the people count, not a second radio list.
