    T54PRO-ZE vs IPC-Color4M-TZ

    The SMALLER the aperture number, the "bigger" it is ... so more light is let in ... F/1.2 is actually better than F/1.8.

    Slow download speed of recordings in SmartPSS Lite

    I doubt you could buy a (micro) SD Card these days that is NOT capable of at least 10 MBYTES/sec ... and therefore able to saturate the 100Mbits/sec Ethernet connection. So that is NOT a bottleneck! BTW, as someone who did the referenced post, an easy "end-to-end" test of your connection is to...

    IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results

    I agree with all that you guys wrote above ... and yea, comparing the T54PRO-ZE and 5442-S3 using the SAME(!) settings (to see if the sensor/lens improved) may not be easily doable. Ideally (again!) shutter speed should be straightforward - in the examples above 1/10s (locked - not 0-10msec)...

    IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results

    Here's the exact same setup after turning on BOTH onboard IR lights (with max manual settings) which adds a little bit of light to the scene.

    IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results

    For grins, I moved the external IR illuminator to the edge of the roof ... so it's closer to the driveway and therefore more lit-up ... and I was able to increase the shutter speed to 1/10s. As before, other params are iris 100, gain 0, and NR 0 ... as I'm trying to just compare the IR...

    B54PRO-Z4E first impression

    The underlying OS must have CPU/Memory/Performance monitor - be really nice if we could see this easily!!!! P.S. I run mine at 10/15 FPS ... as I don't see a need to capture MORE images ... but I certainly want BETTER images ... ;-)

    B54PRO-Z4E first impression

    This picture is real good example of what I mean when I say that the "3D NR multi-frame averaging'" of the 54PRO may be overly aggressive ... which provides a cleaner STATIC image but would cause more motion blur. The brick, grass, etc. look pretty decent ... but several examples associated...

    B54PRO-Z4E first impression

    LOL that would be nice ... but perhaps more realistically, I would suggest @EMPIRETECANDY that you keep enlisting folks to test new firmware ... and ideally new camera's. Let me know Andy when you have that BIG SENSOR camera with an F/1.0 lens! ;-)

    B54PRO-Z4E first impression

    Remember how Dahua should hire Mrs. @bigredfish for hair testing? Now they need to hire Mr. @bigredfish for golf cart testing! ;-) BTW, that's actually a nice "moving object" test situation since I'm guessing you have a lot of golf carts go by at similar speeds. LOL @lookee with "Haunted...

    IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results

    It's possible (but unlikely) that IF the 54PRO is LESS sensitive to IR, that in order to expose the picture properly, it has to run at slower shutter speed and/or higher gain ... which would both contribute to motion blur. So that's why I was trying to assess using locked down exposure settings...

    B54PRO-Z4E first impression

    I'm thinking that compared to the 5442, the "3D NR multi-frame averaging" of the 54PRO may be overly aggressive ... which provides a cleaner STATIC image, but would cause more motion blur ... and also when you have scene changes such as caused by fog.

    B54PRO-Z4E first impression

    Updated my previous comments/posts - "IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results" This ideally should be a fairly simple test - we are just looking at exposure - not sharpness, noise, motion, etc. It's frustrating that my results were not consistent between...

    IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results

    That's a good test @tigerwillow1 ... especially since you used the SAME illuminator to compare 'em. Would have been slightly better to have used an external illuminator so you don't have the light source right on the optical axis of the 54PRO ... but I'm looking at 'em to compare exposure .. and...

    B54PRO-Z4E first impression

    I realize probably a contrarian point-of-view ... but I'm happy with the 54PRO-ZE "upgrade" from my 5442-S3 ... but this is for MY application ... and I agree that there is certainly some "funkiness" with the 54PRO-ZE processing.

    Dahua WizColor 5x59-PRO and SmartLight 5x59-IL new series

    We've got a couple of threads going on about various issues, so I created a separate post specifically about my testing of the "IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results" - title and conclusions updated after further testing. Snippet/summary from thread. In...
