1/2.49" CMOS Sensor
Video Resolution
3840x2160 (8.0 Megapixels) at 25 frames/sec
Lens
f=2.8mm fixed; F=2.0, with IR-cut filter
It is a terrrible cam based on the specs. People get hooked by the marketing of it being 4K which is fine but the sensor is too small and the lens F - 2.0 don't impress. Will take great daytime still photos and videos but when it gets into night motion its not good IMO.

"f" (small f) is focal length, lower numbers are wider, higher numbers are more zoomed in if you will
F (big F) is aperture, lower numbers allow more light in, higher numbers less, the quantity doubles for every 1.4x change, so a F=2 is half as much light as F=1.4 which is half of F=1.0
Sensor size 1/2.5" is on the small side of mid range, 1/1.8" would be probably the largest you'll find in a mainstream affordable camera last I looked. Bigger sensor, more surface area, more light.
Frames per second, I don't get too hung up on this but lower FPS means blurrier/choppier image if something in the frame is moving quickly.
This camera is pretty meh as F=2 is on the slow end and 1/2.5" is on the small end for sensor size.
If you prioritize night vision you may also want to look for STARVIS or BSI (back side illuminated) sensors, I think many are these days but if they tout it usually the camera will be designed around low light use.
