Thanks and i checked those and wanted to know about quality during day and night compare to normal bullet camera DS-2CD2042WD-I
 
there are plenty of images and comparisons here you can search for. I have both of them and the IR on the DS-2CD2T42WD compare to the other is like "night & day" ... a little joke there . ha-ha . But it´s true the IR is way better spread out . and for the distances that is stated . perhaps reduce it with some 30 % at least to get a more accurate distance where the IR is good.

The DS-2CD2042WD-I is a smaller and neater form factor though so it all depends where and how you will mount it. The IR is good enough if it is used properly. but a more round and centered IR compared to the other one.
 
All the 2-series x42 cameras have the same sensor, electronics and firmware, so the only possible differences are:
* Mechanical. Mount options, size, physical appearance. Obviously, your 2 cameras are very different. the "T" is much larger than the regular bullet. See a picture at: https://www.skstore.com.au/image/ca...n/Hikvision-Comparison-IMG_6585-1600x1600.jpg
* Lens. It seems that both use a f/2.0 lens, so no difference there.
* IR. The "T" has multiple substantially more powerful IR power options and that is its main advantage over the regular bullet.
* I/O options (SD, wifi, audio, I/O). Looks like none of these is available for either camera.
 
The turret form factor is better for outside installations.

Not really. IMO of course, but IMO one will have less issues with IR reflection and spider webs with a turret over a bullet or dome form factors.

Ok true dat. On my small bullet I get alot of spiderwebs from time to time. On the "big" bullet nothing so far

That is because your big bullet has exir - separate ir led, like the turret.

I think manufacturers must put up a mirror reflector post at 30 meters and if they can see it in the camera then they say the IR has a 30 meter range. 30% is probably not enough to shave off the IR specs on most cameras.
 
Divide by half minimum. Just completely ignore it actually. Like they actually test it? I mean Hikvision don't even test their firmware releases.
