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

  • Install PointGrab devices, using PoE or WiFi

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

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

Physically installing PointGrab™ sensor devices

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

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…) 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

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


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

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

  • Into the ceiling

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

 Step 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.

Only Shielded LAN cable should be used

 Step 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).

 Step 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):

 Pointgrab 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

Only Shielded LAN cable should be used

 Pointgrab 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

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

 Step 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

 Step 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”

 Step 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

 Step 4. Run Pointgrab configuration tool

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

 Step 5. Confirm you want to set up WiFi

Check box in front of WiFi > select WiFi-button

 Step 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.

 Step 7. Pointgrab reboot

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

 Step 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:

 Step 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.

 Step 2. Check Pointgrab MAC addresses

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

 Step 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
}

 Step 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
(SensorPG1_SensorTypes.EMBEDDED) [D]: Configure
(SensorPG1_SensorTypes.EMBEDDED) [D]: Open Session
(192.168.137.54 SSH) [D]: Opening Paramiko Transport And Connect
(192.168.137.54 SSH) [D]: Connected After: 0.492593
(192.168.137.54 SSH) [D]: Connected After: 0.492593
(SensorPG1_SensorTypes.EMBEDDED) [D]: Close Session
(192.168.137.54 SSH) [D]: Connection Closed After 1.306829 sec
(192.168.137.54 SSH) [D]: Closing Connection

 Step 5. Connect the pointgrabs

Connect the PointGrabs to the network.

On site: installing PointGrab powered using DC power or PoE + connected to WiFi network

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


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

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

  • Into the ceiling

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

 Step 3. Connect the sensor to the Power Source

  • if using DC power (12-24V power), connect the two wires to the corresponding DC wire terminals. Make sure the polarity is correct

  • if using PoE for power: Connect the RJ-45 plug and route the Ethernet cable through the cable lead clips.

Only Shielded LAN cable should be used

 Step 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).

 Step 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.

Quality Assurance

Without the sensor being configured in the Pointgrab 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, check https://spacewell.atlassian.net/wiki/spaces/KB/pages/31064091/Pointgrab+Troubleshooting.

Next steps

After the sensor installation, your Spacewell Implementation Consultant will follow the PointGrab configuration guide, and then will follow the Quality Assurance Occupancy/Utilization Sensorinstructions.

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