    Awesome. Thanks! The online spec sheets are often wrong, as I can set my cameras to 10240, but the spec says it maxes out at 8192. 20Mbps is much better, and is more reasonable for a 4MP camera.

    One more question. Do you know what the max bitrate is at 1080/30 res/framerate?

    For this camera, I was able to contact Andy in regards to the SmartIR and he replied back yesterday saying "The Smart IR we are working on it, no worry. I think can be solved soon.". Can't get an estimate date/time from him but hope this helps :D.

    Just an update:

    I compared the 3.6mm fixed camera in this review (IPC-B5442T-ASE 4MP Starlight+ fixed 3.6mm bullet)
    to the Vari-Focus version (HFW5442E-ZE)

    The fixed lens has better min. illumination specs and it seems to hold true.
    IPC-B5442T-ASE (Fixed) Minimum Illumination 0.001 Lux@F1.6
    HFW5442E-ZE (VF) Minimum Illumination 0.002 Lux@F1.8

    As expected, the fixed 3.6mm lens performed better capturing more light which is clearly seen in the images below.Captures are 13 seconds apart.

    Cameras are literally stacked 1/2" apart, same exact settings; 1/30, Gain 55, DNR50, Defog-Auto.

    The picture from the cam looks fantastic and has convinced me to get a couple.

    I’m sure I saw something posted about the field of view being different to the 5231-ZE. With the 5231-ZE zoomed fully out what mm version of the cam should I get?

    The fixed only comes in 2.8, 3.6, and 6mm

    The full zoom on the varifocal is 12mm

    From the Dahua specs, this model's Angle of View is:
    H: 114°–47°, V: 62°–26°

    5231R-ZE:
    H: 101°~31°, V:54°~17°

    So zoomed all the way out (to max width), this model looks like it "sees" an extra 13° horizontally (114° vs the 5231s 101°) and an extra 8' vertically (62°vs 54°).

    I think I might order a 2.8 and a 3.6?

    So the 3.6 to go here, so effectively zoomed in a bit

    And the 2.8 here, so effectively zoomed out a bit

    Both are mounted pretty high, may get ID on the bottom one, unlikely on the top one

    Yes the top one is in the lowest it could go not ideal. I have them setup to trigger each other so hopefully will get both views when triggered.

    I've just placed my order with Andy for the fixed version as I was impressed with the picture quality posted above Day & Night.

    I have LED street lighting outside the house and in the street so should work fine for my needs.
