So you believe all the marketing hype LOL. Of course they are going to tell you that. And this is with a static image with the shutter slowed down to allow in all the light, but then motion will be a complete blur.
And no, downrezing will not work because it still uses the 8MP "screen" that will need over 4 times the amount of light of a 2MP on the same size screen.
Many of us have been there/done that and the difference between 2MP on a 1/2.8" sensor versus 8MP on the same size sensor is the difference between getting a clean capture of the perp the police can use versus just telling them what time it happened.
Many people start here with the Lorex cameras and then "upgrade" them to lower MP cameras on ideal MP/sensor ratios.
Here is a recent
example someone posted with an 8MP on the 1/2.8" sensor (common combination for a budget camera) versus 8MP on the proper sized sensor - which image looks better to you?
Of more importance is that the top picture is default settings, so a horribly slow shutter of maybe 1/12 so any motion would be a blur. The 2nd picture is a 1/100 shutter and will get a clean capture. The faster the shutter speed, the more light that is needed. That bottom picture at 1/100 shutter is impressive. If the top camera was set to a 1/100 shutter it would be a very dark image.
Almost any camera can do well in the daytime with enough light, even cameras that are 8MP put on a sensor designed for 2MP. But keep in mind that usually the processor and other stuff are still designed around 2MP, so the camera struggles trying to keep up with 8MP worth of data.
So buying an 8MP camera on the same sensor as the 2MP processor means that the processor is potentially working 4 times as hard for the 8MP camera. The camera you are looking at is designed for 2MP, so when they pop an 8MP lens on it, the processor is still the same and has to work harder. In some situations that is problematic.
Take a look at this thread I created that is a good study for NOOB on the value of MP/sensor ratios and the importance of focal length over MP.
At the urging of several folks here, I created a thread to show the importance of focal length and how focal length can be more important than megapixels (MP). I mentioned some of this in the post regarding The Hookup’s latest video demonstrating different cameras, including one sold from a...
