Sunell Panda Cam Body Temperature Measurement Camera Tested

By Ethan Ace, Published May 14, 2020, 11:53am EDT

Sunell is far less well known than its gargantuan domestic competitors Dahua and Hikvision but the company's 'Panda Cam' is going head to head against them worldwide in the booming coronavirus fever camera market.

IPVM Image

However, the name Sunell is generally not used, as the company's sales strategy is to let seemingly anyone relabel it, including companies like InVid, Watchnet, CohuHD, CBC Ganz, Bolide (cleverly disguised), etc.

We tested the Sunell system and inside this report, we examine:

  • Sunell's accuracy compared to an IR thermometer
  • Sunell's temperature measurement strategy and what it gains and loses from this approach
  • How Sunell misses 'elevated skin temperature' detections
  • How common conditions triggered elevated skin temperature detections
  • How software setup impacts performance and measurements
  • How Sunells's engineering recommendations conflict with their sales and marketing

This is the 4th in our series, joining Dahua Thermal Temperature Monitoring System Tested, Seek Scan Thermal Temperature Screening System Tested and Smartphone Thermal Camera Body Temperature Measurement Tested (FLIR / Seek). Upcoming reports on Hikvision, FLIR, ZKteco, and more on the way.
