Learning Objectives

After reading this article, you’ll be able to:

  • Install PointGrab devices, using PoE or WiFi

Make sure to check PointGrab Xovis hardware & network requirements prior to sensor installation.

Create a sensor plan before going on site, so that all parties are aligned on PointGrab Xovis installation location.

Physically installing PointGrab™ sensor devices

Unboxing

Contents of the XOVIS package:

  • device (lenses covered with protectors)

  • white cover

  • information booklet

  • 2 screws?

Mounting instructions

After defining the sensor layout with your Spacewell Consultant, you'll need to install the physical CogniPoint™ XOVIS sensor devices on the ceiling. The sensor layout that you defined determines the exact installation location , height and view direction of the sensors, and you must make sure that you install the sensor devices according to the defined specifications.

Info

How to keep track of installation location per device? Best practice is to tape the sticker on the Sensor Plan or take note of the sensor ID (number starting with 4000… 4000…) in an excel at the place of installation.

To physically install a CogniPoint™ sensor, use following steps.

Option 1: PointGrab powered + connected to the network using Power over Ethernet

Expand
titleStep 1. Secure the flat ceiling adapter to the ceiling, using two wall plugs and two screws.

Image RemovedImage Removed
Caution: Make sure the view direction marker on the adapter aligns with the required view direction.

Expand
titleStep 2. Route the PoE cable in one of the following ways:

  • Into the ceiling

  • In parallel to the ceiling, through the adapter side openings

Expand
titleStep 3. Connect the sensor to the Power Source

Connect the RJ-45 plug and route the Ethernet cable (RJ-45 (Cat 5e cable or better)) through the cable lead clips.

Note

Only Shielded LAN cable should be used

Image Removed
Expand
titleStep 4. Attach the Sensor to the Adapter

Make sure the view direction arrow is pointing in the required direction. Attach the sensor securely to the adapter (there should be no gaps between the sensor and the adapter).

titleStep 5. Removal of Lens/Sensor Cover

Once the sensor is installed it is important to remove lens/sensor cover (Lens cover of full sensor cover is dependent on production batch). Failing to do so will seriously effect sensor functionality.

Option 2 and 3: PointGrab powered using DC power or PoE + connected to the network using WiFi

Technical specifications

  • Only works with 2.4 GHz Wfi 802.11n.

  • Can handle hidden networks as well.

  • Power input interfaces (Sensors are normal, they expect ethernet first but are configured to WiFi by script described below):

Expand
titlePointgrab v1 (shipped with white package)

  • DC Input: Connector/cable type = 2x Terminal Connector, 12-22AWG (Wire gauge 1.5mm2 / 15AWG); Power rating: 12V-24V

  • PoE: Connector/cable type = RJ-45 (Cat 5e cable or better); Power rating: conforms with 802.3af Class 2

Info

Only Shielded LAN cable should be used

Expand
titlePointgrab v2 (every new project starting 2023 will include v2 sensor; new package design is colored red)

  • DC Input: Connector/cable type = USB-C; Power rating: 5V

  • PoE: Connector/cable type = RJ-45 (Cat 5e cable or better); Power rating: conforms with 802.3af Class 2

Info

Only Shielded LAN cable should be used

Preparation steps (can be done beforehand)

You will need:

  • WiFi-network name + password (password is not saved, but we generate a PSK = hashed combination of password + network)

  • Advanced IP scanner (free software)

  • Power for the PointGrab, either PoE-injector or DC power (12-24V power)

  • Router or similar to connect the laptop and PointGrab to the same network + PoW injector or external DC power for the PointGrab sensor

  • Package with config software for PointGrab:

Configuration of PointGrab on your WiFi network

Expand
titleStep 1. Connect your laptop and the Pointgrab CogniPoint™ sensor device to same network

Connect your laptop and the PointGrab CogniPoint™ sensor device to same network (on a router): both devices need an IP address

Expand
titleStep 2. Check the Pointgrab IP address

Use https://www.advanced-ip-scanner.com/ to detect all network interfaces on the connected router -> PointGrab devices will turn up in the list as “Raspberry Pi Foundation”

Image Removed
Expand
titleStep 3. Add the IP address to the package

Insert IP address into the list on the package (“ip_list.txt”); just add them one below the other if you want to configure multiple PointGrabs for use over WiFi network

Expand
titleStep 4. Run Pointgrab configuration tool

Run "PG device configuration tool" from File (In the root of the package)

Expand
titleStep 5. Confirm you want to set up WiFi

Check box in front of WiFi > select WiFi-button

Image Removed
Expand
titleStep 6. Fill in WiFi network details

  1. Insert SSID name

  2. If network password available: check box and insert password

  3. If network has no password, don't check box

  4. If you have hidden SSID network you can select this also

  5. Run

You'll get a confirmation stating if running the tool was successful.

Expand
titleStep 7. Pointgrab reboot

After a couple of seconds, the PointGrab device will reboot.

Expand
titleStep 8. Confirm Connection to Pointgrab Cloud

  1. On premise: the device will connect to the configured WiFi network, LED will turn off to indicate connection to the PointGrab Cloud

  2. When remote: LED will be blinking blue because the device can’t connect to the WiFi

What do do when your network is not password protected, but devices are whitelisted by their MAC address?

How to extract the MAC address and configure the PointGrabs:

Expand
titleStep 1. Connect ethernet cable to your laptop to run DHCP

Connect a switch to your laptop with ethernet cable and share the internet connection from WiFi to the ethernet connection so that you get DHCP running there.

Expand
titleStep 2. Check Pointgrab MAC addresses

Run the Advanced IP scanner to get the MAC addresses of the PointGrabs when doing the configuration.

Image Removed
Expand
titleStep 3. Configure SSID and no password

Configure the PointGrabs by setting the values in the configuration file to the correct SSID and no password:
network={
        ssid="Telia wifi"
        key_mgmt=NONE
}

Expand
titleStep 4. Run WiFi configurator

Run the WiFi configurator with the IP addresses in the list and got reasonable results like:
C:\Users\xxx\OneDrive - Spacewell\Desktop\pg>Wifi_configurator.exe -m FromFile

In order to install the sensor you must buy a separate mounting plate which comes as an accessory

  1. Fix the drop pole adapter (Mounting plate) onto the ceiling using four M4 screws of your choice. Please define the appropriate screw type depending on the ceiling consistency.

Info

The fixture must be able to carry the fourfold weight of the device, which would correspond to 20N for the sensor.

  1. Pull the Ethernet cable through the hole in the back of the mounting destination and plug in the sensor.

  1. Fit the sensor onto the mounting plate and use the two M4x25 Hex lobular socket flanged button head socket screws to fix the sensor.

Quality Assurance

Without the sensor being configured in the Pointgrab XOVIS and Workplace Platform, there is not much you can check.If the sensor has already been added to the Pointgrab Platform, Pointgrab connection lights should not be blinking or giving any color. If there is a light, checkhttps://spacewell.atlassian.net/wiki/spaces/KB/pages/31064091/Pointgrab+Troubleshooting.

Next steps

After the sensor installation, your Spacewell Implementation Consultant will follow the PointGrab Xovis configuration guide, and then will follow the Quality Assurance Occupancy/Utilization Sensorinstructions to verify the set-up.

In case you encounter any issue with your devices, don’t hesitate to check PointGrab Xovis troubleshooting.
