Happy with cameras but worried about monitors:
"Camera manufacturers seem to be on top of their game when it comes to embracing these higher megapixels; however, the struggle is with the monitors....
Out of curiosity, I "googled" "highest megapixel monitor" and lo and behold, I found an 8MP monitor that is being used mostly in the medical field. But, with a price point of approximately $35,000 per monitor, I don't think the security industry as a whole is ready for that kind of investment."
The short answer is that very high resolution remains valuable with digital zooming for search / investigations (the most typical overall surveillance use case) and for real time digital zooming on objects / areas of interest.
