Mini-Review EmpireTech IPC-Color4M-T

Is the sensor onboard, Sony, Omnivision, or a no-name brand?
 
I told you it was a winner!

It is my new favorite fixed lens camera.

From the two-way audio to be able to send out an audible alarm, to the better imaging, and the dual light option, it is hard to beat.
How does this fixed lens version stack up against the -TZ (Varifocal) Color4M model?
 
What confuses me is the TZ (varifocal version) of this model. It has a fixed Iris control as per the specifications. How does the varifocal compare versus this fixed model? @wittaj
