Geovision 4MP Super Low Cost Turret Tested (EBD-4700)

By: John Scanlan, Published on Sep 29, 2017

~$100 cameras, even for 4MP, are now expected by many dealers, as price cuts and ongoing sales have set this expectation.

At the same time, many dealers are looking for alternatives to Dahua and Hikvision, due to cybersecurity concerns, dealer saturation or simply alternative brands.

A recent Geovision camera, EBD-4700, a 4MP outdoor turret, is challenging or beating pricing of their bigger rivals. So we bought one and tested it vs Hikvision.

Inside, we report on:

  • Full light and low light image quality
  • WDR performance
  • IR range and overexposure
  • IR illumination pattern
  • Lens distortion
  • Bandwidth consumption

See our full results inside.
