Add to list Operates on a long-range wireless LoRaWAN network to report occupancy state anonymously without recording video.

Transmits simple counter or occupancy values over IoT networks, completely bypassing privacy issues.

To further narrow down the selection, consider:

Information on networking hardware or platforms for office utilization is available upon request.

Yes. For desk-level workspace utilization without cameras, I’d focus on under-desk PIR/thermopile sensors or mmWave presence sensors rather than ceiling cameras.

Best options I found

• Milesight VS341 Desk & Seat Occupancy Sensor - $103.85 (Vemco Group)

• Milesight VS340 Desk & Seat Occupancy Sensor - $83.24 (Innon Energy LTD)

• Milesight VS341 Desk & Seat Occupancy Sensor - $105.01 (Innon Energy LTD)

• Milesight VS340/VS341 Desk & Seat Occupancy Sensor - $97.50 (MCCI)

• Milesight VS341 — probably my top choice for an actual office deployment. It combines PIR + thermopile, is designed specifically for individual desks/seats, and claims up to 98% accuracy. Milesight describes the VS34x family as intended for hot-desking and workstation utilization.

• Milesight VS340 — similar concept but PIR-only, making it a simpler/lower-cost option. It's designed specifically to report desk/seat occupied vs. unoccupied.

• Disruptive Technologies Wireless Desk Occupancy Sensor — particularly interesting if you want a very small, unobtrusive sensor. It uses temperature rather than a camera, has adhesive installation, reports occupied/not-occupied, and the manufacturer specifies up to 9 years of battery life.

• Occuspace — worth considering if you need floor/neighborhood-level utilization rather than one sensor per desk. Its system uses passive BLE/Wi-Fi sensing and mmWave radar, explicitly without cameras or video.

What I'd choose

If your goal is something like "How many of our 200 desks are actually being used, and which desks are occupied?", I'd start with the Milesight VS341. It is purpose-built for desk/seat occupancy rather than being a general smart-home presence detector.

For a large deployment, I'd evaluate these criteria:

One important distinction: PIR alone can miss someone who sits completely still, whereas thermopile or mmWave can improve stationary-presence detection. Research on under-desk PIR has demonstrated that it can work for long-term desk occupancy mapping, but accuracy depends on the installation and sensing method.

If you tell me roughly how many desks you have (e.g. 20, 200, 2,000) and whether you need real-time desk availability, utilization analytics, or both, I can narrow this down to 3–5 enterprise-ready systems with approximate per-desk cost, connectivity, battery life, and software/API options.

Yes. There are several camera-free desk occupancy sensors specifically designed for workplace utilization analytics. The best choice depends on whether you want simple occupied/unoccupied data, higher accuracy, or integration with an existing building-management platform.

• Milesight VS341 Desk & Seat Occupancy Sensor - $103.97 (Vemco Group)
• Milesight VS340 Desk & Seat Occupancy Sensor - $83.29 (Innon Energy LTD)
• Milesight VS340/VS341 Desk & Seat Occupancy Sensor - $72.50 (MCCI)
• Milesight VS340 LoRaWAN Desk Occupancy Sensor - $71.26 (shopiot)

Good options

• Milesight VS340/VS341 — A strong fit for a modern office. The VS340 uses PIR, while the VS341 adds thermopile infrared, giving you desk/seat-level occupancy without cameras. LoRaWAN versions are useful when you have many desks to cover.
• Sensiable sensiDESK — A compact wireless under-desk sensor using passive infrared/heat and motion sensing. It reports occupied/unoccupied status and is designed specifically for workplace utilization; the manufacturer states that it captures no images.
• Pressac Desk Occupancy Sensor — PIR-based, mounts underneath the desk, and can provide ongoing occupancy updates. It supports local/cloud data and integrations through MQTT, AWS and Azure, which is attractive if you want to feed utilization data into your own analytics system.
• Xandar Kardian CT100 — More sophisticated than a basic PIR sensor. It uses IR-UWB radar, can detect very small presence such as breathing, and explicitly operates without cameras or microphones. It's particularly interesting if you need reliable occupancy even when someone is relatively still.
• AVUITY VuAI — Better suited if you want to monitor a group of desks rather than install one sensor at every workstation. Its motion zones can provide seat-by-seat analysis, while the system reports occupancy without PII.

What I'd choose

For individual hot-desk utilization, I'd start with the Milesight VS341 or Pressac. For a large deployment, I'd favor LoRaWAN because you don't need to put every sensor directly on the corporate Wi-Fi network.

If privacy and detection of people who sit very still are especially important, the Xandar Kardian CT100's UWB radar is worth considering.

One important distinction: PIR sensors detect heat/motion, so someone sitting exceptionally still can sometimes be missed. Radar-based sensors are better at continuous presence detection; GSA's occupancy-sensor guidance likewise notes that radar can sense without movement, whereas PIR relies more heavily on motion.

If you tell me your approximate number of desks, desired budget per desk, and whether you already have Wi-Fi, LoRaWAN, or a building-management system, I can narrow this down to 2–3 systems and compare price, accuracy, battery life, connectivity, and software/API integration.

When tracking desk occupancy without cameras, privacy-compliant solutions generally rely on Passive Infrared (PIR), Thermal/Heat, Microwave/Radar , or Under-desk/Surface Sensors.

Several reliable options fit various deployment types and budgets:

• Milesight VS341 Pro Desk & Seat Occupancy Sensor Go to product viewer dialog for this item. : A tiny, non-invasive, dual-technology sensor designed specifically to mount under desks or on seats. It offers high-precision anonymous detection without capturing any video or images.
• Elsys EMS2 Desk Sensor Go to product viewer dialog for this item. : A Scandinavian-designed wireless sensor meant to mount discreetly underneath a desk. It measures desk occupancy via internal sensing technology along with temperature and humidity, running on a long-life replaceable battery.
• Yealink RoomSensor Go to product viewer dialog for this item. : An enterprise-grade wireless Passive Infrared (PIR) sensor that mounts cleanly on walls or ceilings near work areas/rooms to track motion and occupancy via Bluetooth without video surveillance.
• Discreet Thermal / Heat-based Sensors : Many corporate spaces use overhead or corner-mounted thermal footprint counters (like specialized non-optical infrared grid arrays) that map body heat signatures as simple coordinate data rather than recognizable pictures.

To help narrow down the best fit, tell me:

• Are you looking to mount the sensors directly under/on each desk , or overhead/on walls to cover a cluster?
• What kind of IoT network or platform (e.g., LoRaWAN, Bluetooth, Wi-Fi) does your facility use?

Yes. There are several camera-free desk occupancy sensors specifically designed for workplace utilization. The main technologies are PIR/thermal sensing, thermopile, and mmWave radar.

Best options I found

Milesight VS341 Desk & Seat Occupancy Sensor

$103.09

Milesight VS340 Desk Occupancy Sensor

$70.66

Milesight VS121 AI Workplace Sensor

$383.40

Logitech Spot Presence & Environmental Sensor

$498.99

For a desk-by-desk deployment, the VS341 is probably the first product I'd evaluate. It combines PIR with thermopile sensing and is specifically designed for desk/seat occupancy rather than generic motion detection.

Another particularly interesting option

Xandar Kardian CT100 uses IR-UWB radar rather than a camera. It is designed specifically for desk occupancy, measures presence and dwell time, and the manufacturer states that it collects no images or audio. It claims 99.9% presence-detection accuracy.

Sensiable sensiDESK is another purpose-built option: a small wireless PIR sensor mounted under the desk, with claimed 2+ year battery life and real-time occupancy data. The company explicitly states that it doesn't use camera imaging.

What I'd choose

• Lowest-complexity desk deployment: Milesight VS340/VS341
• Higher precision / privacy-sensitive environment: Xandar Kardian CT100
• Large office with utilization analytics across zones: Milesight VS121 or a workplace analytics platform such as VergeSense
• Very low-maintenance wireless deployment: Sensiable sensiDESK

One important distinction: "camera-free" doesn't necessarily mean "identity-free." For maximum employee privacy, I'd favor sensors that output only occupied/unoccupied, dwell time, or aggregate counts rather than devices that transmit imagery for cloud processing. ASC, for example, explicitly markets its workplace solution as presence-only with no cameras or identity data.

If you tell me roughly how many desks you need to monitor (e.g. 20, 100, 1,000+) and whether you need a dashboard/API, I can narrow this down to 3–5 systems and compare sensor price, battery life, connectivity, accuracy, software/subscription costs, and deployment requirements.

What I'd choose

One important distinction: PIR sensors are inexpensive and excellent for “occupied/unoccupied,” but can miss a person who remains very still. Thermopile or mmWave approaches generally provide more robust presence detection.

If you're deploying this across an office (e.g., 50–500+ desks), I can also narrow this down by price per desk, battery life, wireless protocol, API/integration options, and whether it can feed Power BI/office-management software.

1. Milesight VS340 / VS341 — my first choice for individual desks
These are specifically designed for desk/seat occupancy. The VS340 uses PIR, while the VS341 combines PIR with thermopile sensing for improved detection. They're wireless and suited to measuring which desks are actually being used.

2. Logitech Spot — best for enterprise workplace deployments
A battery-powered mmWave radar sensor designed for workplace occupancy, with additional environmental measurements. It communicates over LoRaWAN and is designed for privacy-preserving occupancy monitoring rather than video.

3. Pressac Desk Occupancy Sensor — simple, purpose-built solution
Uses PIR and mounts underneath the desk. It can provide occupancy updates to local or cloud systems through Ethernet, LTE, or Wi-Fi gateways, with MQTT/AWS/Azure integration.

4. Sensiable sensiDESK — wireless desk-level analytics
A compact PIR-based sensor that attaches under the desk and reports occupied/unoccupied status over a low-power mesh network. The manufacturer claims up to two years of battery life.

One important consideration

If employees may sit very still for long periods, I'd favor thermopile or mmWave over ordinary PIR. PIR primarily detects movement, whereas radar can detect very small movements from a stationary person. The U.S. General Services Administration also notes this distinction when comparing occupancy technologies.

For a typical office, I'd narrow it down this way:

If you tell me roughly how many desks you need to monitor (e.g. 20, 100, 1,000) and whether you already have Wi-Fi, LoRaWAN, or another building-management system, I can narrow this to 2–3 specific systems and compare sensor cost, gateway requirements, battery life, accuracy, and software/analytics.
