Looking to add Cameras at home.....

Great info and I continue to read documents and drawing things out.

Looking for input on these cameras
Key differences between
Loryta IPC-T2431T-AS Fixed Lens 4MP vs Loryta IPC-T5442TM-AS Fixed Lens 4MP


Loryta IPC-T5442TM-AS Fixed Lens 4MP vs EmpireTech IPC-T5442T-ZE White 4MP

The ZE is Vari-Focal but is there anything else the ZE has over the AS?
 
the most import thing on a camera is the CMOS sensor size, bigger is better.
The 2431 has a sensor 1/3
the 5442 has a sensor 1/1.8 -- bigger better in low light .
