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

curious how it compares to its non-oem uniview counterpart.

Will the GEO accept UNV firmware?

Just because the housing is the same as unv it does not mean the chipset or sensor inside is the same. 

As undisclosed 1 said it would be interesting to see direct comparison to UNV branded model.

My point of view, those h/w will be same at least.
4MP sensor for surveillance purpouse seems to be the exclusive place of OV4689.
From the unit price point of view, encode chip have to the same possibility. that is probably Hi3516A.
But I can't know of truth until disassembly. I expect further research by IPVM.

Just because the housing is the same as unv it does not mean the chipset or sensor inside is the same.

How do you feel about the both serial numbers starting with 210235?

Their speed dome camera such as SD2322-IR is also UNV's OEM, unfortunately.
I'm very worried that OEM cam will replace genuine cam.

Thanks, for  knowledge updates.
