Density Sensors are designed to work on all common Enterprise network configurations while allowing easy and secure access and data transmission to our cloud services.

Connection Types

  • 1 x Gigabit Ethernet 10/100/1000 (preferred)

  • 1 x WiFi 2.4GHz (requires the Density Unit Setup App to locally set up the device)

    • Note: Wireless should not be used for a deployment consisting of more than 10 density sensors, as this can lead to network congestion and a poor user experience

Power Requirements

  • Entry: PoE+ 802.3at, 30W

  • Open Area: PoE 802.3af, 15.4W

Unsupported Connection types:

  • Network with captive portal

  • Network with proxy server

  • 802.1x wired authentication

  • 5GHz Wireless

  • WPA2 Enterprise

  • Hidden SSID (Note: Can be used if temporarily made visible during initial provisioning)

Switching

Density sensors are compatible with most enterprise-grade unmanaged switches that meet the above power and network requirements (30W per Entry and 15.4W per Open Area Sensor)

IP Configuration

Density sensors must be assigned an IPv4 or IPv6 address. Most commonly this is done via DHCP, although static IP addressing is also supported, via our Unit Setup mobile app. A DNS server must also be configured.

Network Bandwidth

Density sensors communicate with the Density cloud service and use an average of 1-3 Kbps / per Entry sensor, and 5-10 Kbps / per Open Area sensor. Please ensure the network being used is able to support this amount of traffic for the number of devices being installed.

Device Updates

Density sensor software is automatically maintained by Density using an OTA (over-the-air) software update system. Density will notify customers when a new update is available and will schedule, perform, and monitor sensor software updates for all online sensors.

Firewall/Whitelisting

Density sensors need to be able to communicate with the following Density services. All communication from Density sensors is outbound, over HTTPS (port 443) unless otherwise specified below. Please whitelist the following services on your firewall:

  • *.density.io (ports 443, 8443)

  • *.amazonaws.com

  • *.gstatic.com

If using Public DNS, please ensure the following are whitelisted (optional):

  • 8.8.8.8

  • 8.8.4.4

For NTP and time synchronization, please ensure the following are whitelisted:

  • *connman.net

  • *.ntp.org (port 123)

Proxy Servers

Density Sensors do not support networks that require a web proxy, or that require SSL inspection. Please configure the network’s firewall to whitelist the services listed in the Firewall section above.

Static Provisioning

There is no need for the Unit Setup app if you choose to use DHCP on ethernet. For static provisioning, there is no alternative - you must use the Unit Setup App provided. For more information on how to use the Unit Setup app, refer to this guide.
