Wired Sensor Configurations: Power and Data Over Ethernet

VergeSense wired sensors have flexible and reliable network configuration options. The Power and Data Over Ethernet option uses IEEE 802.3af PoE protocol over an ethernet cable to provide the sensor with both power and data. PoE makes the deployment of sensors a breeze and ensures the most stable and reliable data connectivity. Simply install the sensor and plug in the PoE ethernet cable.

Data Flow


Data Flow: Sensors > Network

  • Each sensor requires a PoE connection (home run to a PoE port)

  • The sensors collect and process raw data into JSON

Data Flow: Network > Cloud

  • JSON file sent from SENSORS to the VergeSense Cloud via ethernet connection to the corporate network

  • All data in transit is encrypted using TLS 1.2

Network Requirements

DHCP: Dynamic IPs assigned by the network

DNS Safelist, Open port: 443

Cabling and Power Requirements

  • Cat5e, Cat6, Cat6a

  • Sensors are PoE class 2 (802.3af)

  • Average consumption ~4 Watts

  • Peak consumption <8 Watts


Frequently Asked Questions

The following answers apply to wired sensors. 

  1. What protocols are used to send data from sensors to the cloud? VergeSense wired sensors can send data over an 802.3af PoE or WiFi 802.11 a/b/g/n (2.4 GHz) network.

  2. How is data encrypted? Data-in-motion is encrypted using TLS 1.2. All cloud-hosted databases are encrypted using AES-256.

  3. What is the volume of network traffic? Do the sensors cause network interference? Data is sent in small packets and in staggered intervals, thus preventing spikes in network traffic and network interference. Data is processed locally on the sensor and each sensor sends ~1 KB of data to the VergeSense Cloud every 1 minute.

  4. How do sensors receive firmware updates? The sensors automatically deploy device updates when available. As the sensors send data to the cloud, they also check for available device updates. If an update is available, it is downloaded and installed. For security purposes, all communication is outbound from the sensor to the cloud; there is no cloud-to-sensor-initiated communication inbound.

  5. What type of data is collected? Where is data processed? The sensor continuously captures raw data using its wide-angle (170 degrees) fisheye lens. The raw data is a 352x288 array of pixels, which is processed locally on the device through a neural network pipeline. Processed data (anonymous person counts in JSON format) is transmitted to VergeSense’s cloud analytics portal through an on-premise network. Devices can be configured to operate within the corporate firewall. All cloud communication uses TLS 1.2 encryption. After completing processing, the raw sensor data is discarded (it is only temporarily stored in RAM).

  6. How long is raw sensor data stored? Raw data is processed on the sensor itself and discarded within seconds.
