Sorry for my question but what is the difference apart from the price?
Also the S2 has slightly better low light ability i Have them both and they both are great. You should also use more lighting at night and these cameras show great detail at night in color with using bright white 5000k lights.

Is there a way the varifocal will tell you on the screen what mm you're looking at? i wanted to use this camera in various locations and adjust the focal point to see if i needed to order 2.8,3.6,6mm, etc cameras. the IPVM tool doesnt do it for me.

There's a multi-step way to do it:
On your camera, go to the Zoom and Focus tab and hover your mouse over the current zoom setting. The browser should display a value for a few seconds. It was a PITA to grab a screenshot, but if you look closely below (it snapped the screen right as the value was fading out), you'll see the value is 300. Write that down.

You also need to know the highest zoom value, so zoom the camera all the way in and record that value. For my camera (older 5231R-Z), that value is 1400.

Take those values and click Tools > Focal Lens Calculator at the top of IPCAMTALK.COM (blue menu bar at top of this browser tab).

For the top left, enter in your camera specs. They will differ from mine below. For the T2231T-ZS, your Fmax would be 13.5, Fmin would be 2.7, and Zmax would be whatever value max zoom value you got from that camera.

Then go to the bottom right and put your zoom value in the Zsp box and it should tell you the MM.

So for my camera, a zoom value of 300 = 4.7mm.

thanks aristo! the 2231T goes from 0-2343 when i max it out and hover my mouse over the slider. so if my calculations are correct we get the following:

2.8mm = 21
3.6mm = 195
6mm = 715
12mm = 2017

here's a photo of the camera on the side of the house, my goal is to cover the two windows directly on the wall below the camera. i figured i'd need a 6mm for this shot. this is the 2231T factory defaults.
