Set up your IT network as needed for PointGrab installation

Hardware Requirements

PointGrab CogniPoint™ sensor devices are a wired solution. So make sure that you are allowed/able to foresee cabling and drill holes in the ceiling where needed.

The PointGrab CogniPoint™ sensor devices can be installed in 2 different ways:

1. powered + connected to the network using Power over Ethernet

2. powered using “DC power” or PoE + connected to the network using WiFi, with following power input interfaces:

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

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
Power consumption = 4W

Only Shielded LAN cable should be used

Network Requirements

General network requirements for Pointgrab devices

On the network, all devices must have HTTPS & MQTT/TLS access via different ports. Please find below the current “List of IP addresses for outgoing traffic” to know which ports to open.

A Dynamic IP is required.

We sync all our hubs to the same open NTP (network time protocol) servers so we have consistent timings in our data warehouse.

We recommend not to use specific IP addresses or DNS destinations in the firewall as they can and probably will change in the future!

→ The ports will remain the same, so we recommend to communicate / open the ports outbound.

Destination	Port	Server Name Indication	Protocol	Direction	AL description

Destination	Port	Server Name Indication	Protocol	Direction	AL description
upgrade.pointgrab.com	443		TCP	Outbound	Upgrade sensors firmware version
debug.pointgrab.com	443		TCP	Outbound	Sensor should be able to push logs to this endpoint so debug the issues with the sensor
pki.pointgrab.com	443		TCP	Outbound	Automatic Sensor certificate updates
iot.pointgrab.com iot2.pointgrab.com	8883	iot2.pointgrab.com	TCP	Outbound	Telemetry data push

(*) Network should support local NTP Server (DHCP option 42) or provides access to one of the
following external NTP servers:
• 0.ubuntu.pool.ntp.org
• 1.ubuntu.pool.ntp.org
• 2.ubuntu.pool.ntp.org
• ntp2.aliyun.com
• ntp4.aliyun.com
• ntp6.aliyun.com
• time2.google.com
• time3.google.com
• time4.google.com

Specific network requirements for Pointgrab devices connected to the network using WiFi

Supported WIFI gigahertz frequency differs depending on the Pointgrab version used:
- Pointgrab v1 (shipped in white package): supports 2.4 GHz WIFI 802.11n.
- Pointgrab v2 (new package design is colored red; serial number that starts from 3000040): both 2.4GHz and 5GHz WIFI are supported.
PointGrab v1+v2 can handle hidden networks
PointGrab v2 sensors can handle Open WIFI also

If you have PointGrabs using WiFi, make sure to set up the WiFi Access Points so that they don't drop the relevant GHz bands when there is lots of traffic on the specific WiFi AP.

It might look like the WiFi is up and running, but the PointGrab sensors go offline and might come back online, or they will just stay offline with the blue LED on and will require a restart (power cycle) to come online again.

FAQ

Yes, a sensor that was used on wifi can be relocated and work on POE in the new location.

Also good to know: there is then no reconfiguration needed.
