Experience with adjusting your camera matters a lot - this calls for sticking with what you know best as an integrator or dealing with competent distributors that can give you the right settings.
In the cameras we deal with, we have found:
1. the WDR level/mode has typically been set to an non-optimal level for the majority of applications
2. Max gain is too high
3. Min shutter speed is either too low (1/4s) or to high (1/60s)
4. bitrate is either too low (artefects everywhere) or too high (network overload issues)
The list goes on.
Pretty much any camera using Aptina, Sony or Omnivision's 1/3" or larger 60FPS true WDR sensors can be adjusted to achieve acceptable results in any indoor or outdoor daytime environments - provided that: a) the lens is good and b) the web interface allows everything to be adjusted.
In terms of night vision - Axis and Bosch stand above the rest as tier 1 performers each with their own "secret sauce" noise reduction and gain engines (Lightfinder and StarLight).
Below that, we have vendors that provide 3DNR + 2DNR - which gets rid of most of the "sprinking" noise for good mono night vision, but do not have the nighttime colour ability of Lightfinder/Starlight. Lilin is in this group together with quite a few reputatble manufactuers like Sony, Panasonic, Pelco, Avigilon, IQinvision, Honeywell, Dynacolor (Razberi, Micronet, etc), Probe (Digital Watchdog), Dahua (IC Realtime), Hikvision, CNB, Brickcom, Geovision and Vivotek.
Worrying about product quality based purely on the brand name itself will not get you very far - because that kind of thinking leads to the lack of competition, product innovation and price increases (think Honeywell) - from my point of view - the best way to gauge product quality is to examine the cameras's physical quality, disassemble it to check the interior quality, check the picture quality and software features.
