Installation Guide

This section guides you on how to correctly mount Portal Beam. There are two scenarios covered—how to mount Portal Beam for room occupancy and desk occupancy due to Portal Beam wide angle thermal camera nature. There are differences in coverage for both of these scenarios.

What's in the box

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



On the side of the device you can find:

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


All of the above are covered by device casing, and are not visible for users.


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

Occupancy monitoring

For occupancy features it is crucial to calculate the coverage correctly and mount Portal Beam in the correct part of the ceiling depending on what area you need to monitor. Portal Beam is equipped with a Far Infrared Wide Angle therma camera so the coverage depends on how high it is mounted. The lowest point you can mount Portal Beam is 2,4m and the highest is 4,0m to achieve 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 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

As Portal Beam needs to be able to see the thermal image of the 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 average people height of 185cm.

Mounting options

Tape Mount

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


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
