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:
powered + connected to the network using Power over Ethernet
powered using DC power or PoE + connected to the network using WiFi, with the advantage of segregation from your main network (this involves creation of a separate WLAN /WiFi-IoT network)
if you have PointGrabs using WiFi, make sure to set up the WiFi Access Points so that they don't drop all 2.4 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.

Remember: Connecting CogniPoint™ sensor is not possible using 4G |
Network Requirements
On the network, the 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.
→ The ports will remain the same, so we recommend to communicate / open the ports outbound.
(*) Network should support local NTP Server (DHCP option 42) or access to one of external NTP servers shown at port 123 |

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. |

Pointgrab does NOT recommend using wifi and POE connectivity together, because the 2 connectivity types could interfere with each other. So POE cannot be a “fall back” for wifi.
The PointGrab team suggests using different subnets for WiFi and Ethernet connections:
