This is interesting to me, the 4kt in @jmcu excellent videos looks fantastic quality, I guess it would make sense that 8MP sensor will require more light. I have some of the 54Pro cameras arriving and my guess is these will fair better with the onboard only lighting than the 4kt, would that be a fair assumption?

Regardless the sensor on that 4kt looks superb, path detail and general exposure, I guess the downside is lack of IR if that is an issue for some. It almost looks too good to be true! :clap:

The 4KT is on a larger sensor 1/1.2" vs 1/1.8". That's why it can get away with being 8mp and still deliver a better night time image. It doesn't come down to pixel count alone but pixel size when it comes to delivering good pictures in low light and putting more pixels on the same sensor size, means reducing the individual pixels in size, hence why 8mp on 1/1.8" isn't recommended as the pixels size is such that the light gathering ability isn't great. 8mp on a 1/1.2" though is a whole different ball game. The extra real estate allowed for not only more pixels but potentially larger more sensitive ones as well. That's why the 35mm camera from 2016 has the best night picture of all. It was either 8 or 12mp (I forget) but 35mm is huge compared to even 1/1.2" so by comparison, the pixels were huge and gathered much more light. That said all cameras have advantages and disadvantages. eg the 35mm I mentioned came in around $10k with lens!!! The 4kt's have numerous areas some of us would wish were improved. I'm sure you'll find the same with 5442's and even the new 54 pros as you can tell from what some of us are observing. The thing with all of these is not to see it as rubbishing the camera but just critique and realise no camera is perfect. Sometimes feedbakc leads to improvements, sometimes not. However, I'll always give honest critique in the hope it will help improve things and so I and everyone else know what the strengths and weaknesses of any given camera are. IT's all about finding the best of the best, then the best of those that fit your needs / compromise. The perfect camera doesn't exist, so far at least...

interesting he’s running 1/60 and very little blur

Sometimes it depends on the angle and distance to the camera, Moving left to right as opposed to straight at or away, also results in more relative movement. When I had my issue with blur I had 6ms set which should have been plenty, but when I was close up one night, when I reviewed the footage, I blurred despite the relatively fast shutter and slow movement. That's why I dropped mine to 4ms max (whenever possible). Prior to that, I'd had no issue at 6ms. 1/60th seems very slow to avoid blur unless eveything in the picture is static or moving directly at the camera.

Thanks for the detail, I am a full frame camera guy so understand the theory, still that 8MP is impressive, I will be adding one to my next order along with a 54Pro AS it would seem! kind of annoyed because I almost ordered the two mentioned and a ZE, instead I got three ZE's which was stupid in hindsight. Not to worry, can never have too many cameras and I still have two which need upgrading anyway. Re the video clip showing blur from the scooter riders, of course that will not be a useful still image but during playback it isn't too shabby considering the shutter speed. The motion is angular to the camera also, half way to the subject coming towards which will help with the motion blur to some degree as mentioned above.

Yeah the 1/60 is fine when the target is under that streetlight, but close in and someone at your door you're going to have to run faster shutter, at least 1/120 (0-8.33) and let the camera turn on the white LED's on motion

You know you can set the white LEDS to come on with the IVS tripwire for a set period of time, like say 20 seconds

Do you mean the warning light under ivs?

This is looking pretty impressive so far, the ambient will be helping though. Once the on camera LED's are running this should look very nice! again, thanks for posting these and taking the time :clap:

Quite pleased I have some ZE's coming now, nobody mention the AS :wtf:

I can only imagine how many cameras are at @CamCrazy's house ... ;-)

The scooter footage is "illuminating" (pun intended) as @CCTVCam points out, since because there the floodlight isn't on, the gain (and NR) has to get pushed up.

This is why I'd be curious to see footage with NO lights (and in color of course) ... and especially if you do a shootout against the T54PRO-ZE (thanks in advance for doing as I saw you responded), that seems like a good test to compare the "raw" capability between the two cameras.

P.S. @CamCrazy - when you do your shootout, you should toss in a picture taken from your full-frame camera ... just to show that when it comes to sensors, size matters! ;-)

On the one hand too many, on the other not enough. It is a necessity and hobby which got a bit out of hand, no doubt others on here in a similar position. Researching and testing is fun, some of my original 2mp starlight cameras have been up since 2018-19, not a bad service life, I only have 3x 5442 out of 12 cameras in total, one of those is purely ALPR and two are PTZ's, the rest are at critical pinch/entry points. Planning to upgrade 7 by the time I get another order through, then they will all be 4MP with two 8MP added in the mix.

Looks like @Chokolinho could be posting some more videos tomorrow which will be great to see, so far it is looking quite promising.

Once mine get installed I will take a while for proper feedback, although will post first impressions pretty quickly once setup with usual manual configuration. Keep the images and videos coming :thumb:
