Hello everyone,

I'd like some help on choosing a Speed Dome for monitoring a high rise, that some residents drops drash onto our property, Here is the a picture of the skyrise. It is close to 300M tall will get an IR300M. I am torn between getting a

Cam 1 - 5MP PTZ Smart IR 300M IR-CUT Super Low Illumination 36X IMX355
Cam 2 - 5MP PTZ Starlight Night Vision Laser Infrared 300M 36x Optical Zoom IMX 355
Cam 3 - 8MP 4k PTZ IR 300m 20X Optical 10x Digital Zoom

Although I know 36X optical soom is better than 20X Optical 10x Digital Zoom, I need to keep the camera zoomed out most of the time (like what you see now). Since I need to keep an eye on all units. I am thinking if I get 8MP I can capture MORE detail at 4k resolution and potentially allow Blue Iris to track even very small falling objects. But Cam 1 on the otherhand seems to have the best IR. But there are many lights all around the area so do I need Super Low Illumination or would that do more harm than good?

I can't afford an 8MP with 36X Optical and Super Low Illumination as it would cost 3x more and I don't have the money for that.

Attach are pictures on my older 2MP 30x PTZ Camera with 150M IR
