Right here · In this room · Nearby ### Distance, not just signal Each device's signal is turned into an estimate in meters, adjusted for open space, an ordinary room or walls in between. AirTag · Tile · Chipolo ### Trackers called out Known trackers are recognized from what they broadcast and flagged the first time each one is heard. 60 makers · 32 services ### What each device is Makers are named from the company code a device broadcasts, and common services like Heart Rate or Battery are spelled out in words. ## See it in action ![Find it mode showing 1.4 m, Warmer, and a rising signal graph for the last minute](https://evlarsoft.com/apps/bluetooth-detective/s2.jpg) Walk around and watch the number.

It never pairs or connects. ## How a PC can tell how far away a device is Most Bluetooth gadgets announce themselves several times a second so phones and computers can find them. Those announcements carry a name, sometimes a maker code, and arrive at a measurable strength. Signal strength falls off with distance in a predictable way, so a strong signal means a device is close and a weak one means it is further off. Walls, bodies and furniture soften the signal, which is why the app lets you say what kind of space you are in. It is an estimate, not a tape measure. It is very good at telling you which of two devices is nearer, and whether you are getting warmer as you walk. Bluetooth carries no direction, so to find a lost device, turn slowly on the spot and walk the way the reading improves. ### How to find a Bluetooth device with your PC Bluetooth Device Scanner lists every device advertising near you with a signal meter and an estimated distance. To track down one in particular, use Find it and follow the reading. - Set the kind of space you are in, open space, an ordinary room or walls in between, so the distances fit it. - Find the device in the list, open it, and press Find it. - Carry the PC and watch the large distance readout, which refreshes four times a second with the last minute of signal drawn beneath. - Walk the way it says warmer, and turn on the ticking to sweep the room without looking at the screen. - If it holds steady, turn slowly on the spot; your body blocks the signal, so walk toward the direction where it peaks. ### What a Bluetooth scanner can tell you about each device Open any device for its details: the maker, named from the company code it broadcasts for sixty makers, the signal in dBm, its transmit power and the services it offers. Thirty-two services are spelled out in words, such as Heart Rate, Battery, Keyboard or Mouse, and Eddystone Beacon. Apple devices are told apart from what they broadcast, so you see AirPods or Beats, Watch is nearby, Apple TV or HomePod, or Find My tag rather than a bare address. Devices Windows is already paired with are listed too, marked as paired or connected. ### Reading the list: rotating addresses and devices that go quiet Nearly every phone and tracker advertises a randomized address that changes every quarter of an hour. That is deliberate, and it is why one phone can appear as several rows over an evening. A name you give a device is kept against its address for as long as that address lasts. Devices advertise in bursts, so one that goes silent for a minute has usually not left. Instead of vanishing from under the pointer, it moves to a Gone quiet section below the list, folded away until you open it. ### Scanning for AirTags, Tiles and Chipolos Trackers are recognized from what they broadcast and called out the first time each one is heard. Close the message and it stays closed until a tracker you have not seen before appears, which raises it again. The scanner only listens. It never pairs or connects, changes nothing on your PC or anyone else's device, and nothing leaves the PC unless you save the list yourself as CSV or JSON. ![](https://cdn.evlarsoft.com/related/v1/icons/bluetooth-detective.png)**Bluetooth Device Scanner**Utilities & tools One payment.

[Ask us](https://evlarsoft.com/contact?topic=support&app=Bluetooth%20Device%20Scanner) ### Does it pair with or connect to anything? No. It only listens to what devices broadcast in the open, and changes nothing on them or on your PC. ### Why does one phone show up several times? Phones and trackers change their Bluetooth address every so often for privacy, so the same device can look new. Names you give are kept against the address it is using. ### Can it prove there is no tracker on me? No. It finds trackers that are broadcasting. A tracker sitting near its owner's phone can stay quiet, so an empty list is not a guarantee. ### Why don't my keyboard and mouse show a distance? Many of them use older Bluetooth that does not broadcast. They are listed from Windows' own paired devices instead, without a signal reading. ### Does it need the internet or an account? No. Everything happens on your PC. ### Which versions of Windows does it run on? Windows 10 (version 1809 or later) and Windows 11. ### Is it a subscription? No. Bluetooth Device Scanner is a one-time purchase of $2.99, and updates are included. ### How do I get it? Buy it on this page and your license key arrives by email.

When something moves it saves a clip — and because it is always holding the last few seconds, the clip starts before the motion did, so you see what caused it rather than what followed. Choose the camera, the sensitivity, how long it keeps rolling, and where the clips go. It records at whatever resolution your camera offers, sounds an alarm if you want one, and keeps watching from the notification area after you close the window. $1.99 · lifetime · 3.6 ](https://evlarsoft.com/apps/webcam-motion-detector) More in this category ## Network and web [All 23](https://evlarsoft.com/apps/category/network-and-web) - [ARP Table Manager](https://evlarsoft.com/apps/arp-table-manager) - [Battery Report](https://evlarsoft.com/apps/battery-report) - Bluetooth Device Scanner - [CPU Core Load Reporter](https://evlarsoft.com/apps/cpu-core-load-reporter) - [DNS Switcher](https://evlarsoft.com/apps/dns-switcher) - [Easy Subnet Calculator](https://evlarsoft.com/apps/easy-subnet-calculator) - [Internet Connectivity Checker](https://evlarsoft.com/apps/internet-connectivity-checker) - [Latency Checker Widget](https://evlarsoft.com/apps/latency-checker-widget) - [Link Maker](https://evlarsoft.com/apps/symbolic-hard-link-maker) - [Link Unshortener](https://evlarsoft.com/apps/link-unshortener) - [Memory Usage Monitor](https://evlarsoft.com/apps/system-memory-reporter) - [Network Adapter Statistics](https://evlarsoft.com/apps/network-adapter-statistics) - [Network Indicator Widget](https://evlarsoft.com/apps/network-indicator-widget) - [Network Monitoring](https://evlarsoft.com/apps/network-monitoring-widget) - [News Ticker Widget](https://evlarsoft.com/apps/news-ticker-widget) - [Routing Table Manager](https://evlarsoft.com/apps/routing-table-manager) - [RSS Keyword Alerts](https://evlarsoft.com/apps/rss-news-alert-notifications) - [Subnet Master](https://evlarsoft.com/apps/subnet-master) - [Subtle Blink Reminder](https://evlarsoft.com/apps/subtle-blink-reminder) - [Taskbar RSS Reader](https://evlarsoft.com/apps/taskbar-rss-feed) - [Tracert Route Tracer](https://evlarsoft.com/apps/tracert) - [Trip Cost Calculator](https://evlarsoft.com/apps/trip-calculator) - [Webcam Motion Detector](https://evlarsoft.com/apps/webcam-motion-detector) Browse by category [Photos and images _54_](https://evlarsoft.com/apps/category/photos-and-images)[PDF and documents _42_](https://evlarsoft.com/apps/category/pdf-and-documents)[Keyboard and mouse _28_](https://evlarsoft.com/apps/category/keyboard-and-mouse)[Audio and music _27_](https://evlarsoft.com/apps/category/audio-and-music)[Files and disks _24_](https://evlarsoft.com/apps/category/files-and-disks)[Developer tools _18_](https://evlarsoft.com/apps/category/developer-tools)[Display and screen _16_](https://evlarsoft.com/apps/category/display-and-screen)[Productivity _15_](https://evlarsoft.com/apps/category/productivity)[Clocks and timers _14_](https://evlarsoft.com/apps/category/clocks-and-timers)[System and battery _12_](https://evlarsoft.com/apps/category/system-and-battery)[Security and privacy _10_](https://evlarsoft.com/apps/category/security-and-privacy)[Video _8_](https://evlarsoft.com/apps/category/video)[Games _6_](https://evlarsoft.com/apps/category/games)[Desktop widgets _5_](https://evlarsoft.com/apps/category/desktop-widgets)[Health and wellbeing _3_](https://evlarsoft.com/apps/category/health-and-wellbeing)[All 305 apps](https://evlarsoft.com/apps) --- Source: https://evlarsoft.com/apps/bluetooth-detective
