Install a Portal Beam

This section guides you on how to correctly mount a Portal Beam.

There are two scenarios covered — how to mount a Portal Beam to monitor room occupancy and desk occupancy due to the Portal Beam wide-angle thermal camera nature. There are differences in coverage for both of these monitoring scenarios.

What's in the box

A Portal Beam is shipped with 3M double-sided tape that is the easiest way to mount the device, a set of batteries, and a mounting kit to screw the device into the ceiling. Also, there is an additional mounting bracket for a suspended ceiling mount (sold separately).



On the side of the device you will find:

  • Reset button - allows you to reset the device
  • Power switch - to power on/off the device when it's running on batteries
  • DC socket
  • LEDs - indicate the state of the device


All of the above features are covered by the device casing and are not visible to users.


Before you begin mounting the Portal Beam to the ceiling, remember to scan the QR code on the back of the device using the Kio Gateway Installer app.

Occupancy monitoring

For occupancy features, it's crucial to calculate the coverage correctly and mount a Portal Beam in the correct part of the ceiling depending on what area you need to monitor.

The Portal Beam is equipped with a Far Infrared Wide Angle therma camera, so the coverage depends on how high it's mounted. The lowest point you can mount a Portal Beam is 7.8 feet (2.4 meters) and the highest is 13.1 feet (4.0 meters) to achieve the best accuracy. Pictures taken by the thermal camera are passed to ML based algorithms that can recognize people-based heat detection on a picture.


Portal Beam checks occupancy once a minute and provides full privacy. No pictures are saved on the device, the only information sent to the cloud is the number of people detected.


You can use the Portal Beam to monitor room occupancy. You can place a Portal Beam on the ceiling in the middle of the square that you need to monitor. Please note, as for now only one Portal Beam per room is supported.

Coverage table

A Portal Beam needs to be able to see the thermal image of a body, please refer to the below table on what coverage is available for room occupancy scenario (standing people).

Mounting Height Coverage Square size
2,4m 2,27㎡ 1,51m x 1,51m
2,6m 3,99㎡ 2,00m x 2,00m
2,8m 6,19㎡ 2,59m x 2,59m
3,0m 8,86㎡ 2,98m x 2,98m
3,2m 12,02㎡ 3,47m x 3,47m
3,4m 15,66㎡ 3,96m x 3,96m
3,6m 19,78㎡ 4,45m x 4,45m
3,8m 24,37㎡ 4,94m x 4,94m
4,0m 29,45㎡ 5,43m x 5,43m


Portal Beam can also be used to monitor desk occupancy, or just sitting people.

Coverage table

Please see reference calculations for desk occupancy, since the distance from Portal Beam to the body of sitting people is greater than for the room occupancy scenario, coverage is slightly increased.

Mounting Height Coverage Square size
2,4m 7,47㎡ 2,73m x 2,73m
2,6m 10,38㎡ 3,22m x 3,22m
2,8m 13,78㎡ 3,71m x 3,71m
3,0m 17,66㎡ 4,20m x 4,20m
3,2m 22,01㎡ 4,69m x 4,69m
3,4m 26,82㎡ 5,18m x 5,18m
3,6m 19,78㎡ 4,45m x 4,45m
3,8m 24,37㎡ 4,94m x 4,94m
4,0m 29,45㎡ 5,43m x 5,43m


Please note, all calculations are based on an average people height of 5.1 feet (185 cm).

Mounting options

Tape mount

  • Step 1: Peel one side of mounting tape and stick it to the back of Portal Beam
  • Step 2: Peel the other side of mounting tape and stick it to the ceiling
  • Step 3: Ready

Ceiling mount

Standard mount needs to be screwed to the ceiling.

  • Step 1: Put wall plugs in drilled holes
  • Step 2: Put the mounting kit against the ceiling and screw it in
  • Step 3: Put Portal Beam to the mounting kit and rotate it gently to lock it

T-rail mount

T-rail mount allows you to mount Portal Beam easily to a suspended ceiling.

  • Step 1: Put all elements together
  • Step 2: Lock trail to the suspended ceiling bar
  • Step 3: Screw standard mount to t-rail mount
  • Step 4: Put Portal Beam to the standard mount
  • Step 5: Rotate it gently to lock it


T-rail mount is not included with Portal Beam and is sold separately
