That's a heck of a lot of work @Wildcat_1 .. thanks!
Personally, from what I'm seeing thus far, I have no doubt I would choose another Color4K-X over this camera though.
Are there any plans for a night review with zoom ? I mean.. nice review, always happy that you invest so much time to show us the products..
but this is varifocal camera,.. so why no zoom ? Most people would buy fixed lens when mounting it like that ?
According to spec sheet the 2831 is F1.9 and this one here is F1.4 , .. so in theory it should be better ?
Just about to put the link up that @EMPIRETECANDY provided. Looks like he has 4 on Amazon right not at $249.99. Link is HERE and I will also update Post #1Awesome job wildcat! What is price of these?
You clearly invest a lot of energy in the production of such videos. Have you intentionally left them unlisted (so they do not return in YouTube search results)?
Also forgot to say, remember the 5842 comes in a Z4 variant so if you need a little more reach That’s another option this cam in that variant can give you.@NightLife thanks for the comments. Yes the Color4K-X is a powerhouse of a cam as I showed in my review of it BUT remember it has a place and its own limits since it a) is fixed (not vari) therefore does have limits on install location based on FOV and target requirements for some and b) does not have IR. Therefore as I mentioned in my 5842 Turret review, these 5842 cams really do have a key role and place in the Dahua portfolio but more critically in anyones overall security buildout. What I mean by that is that they (5842) can either be a primary 4K (with other cams in the mix) based on a particularly difficult FOV (lighting or distance to target perspective etc.) or can augment a Color4K-x at a particular install location. Augmenting a Color4K-x with a 5842 is a great combination because it ensures that should a) you need to target (zoom) on a particular area of an FOV or b) light is problematic or may change without your control, then having the 5842 covering the same FOV albeit from a different angle etc (redundancy is always good in planning a robust security rollout installation) will ensure you get a usable capture. I'll always advocate for having a B&W + Color cam (2 cams) as a minimum covering 1 area (of course depending on size of coverage area). This also ensures that the B&W with IR can give you crisp detail in dark areas or where color cannot keep up with facial detail while the color gives you of course color ID details both of which are great for evidential use should you need to engage LEO etc.
Also in my testing (especially with the newer FW I made mention of RE: SmartIR) there really is no need now not to consider moving from a 5442 (either as an upgrade or at point of purchase) to the 5842 as the PQ is extremely good and light handling does not take a beating as it did in older 4K's. Noise is also similar and in fact almost identical in newer FW. In other words you / we are not having to compromise when adding the 5842 into installs any more. The price between 5442 and 5842 is also narrowing therefore my recommendation if anyone is considering the 5442 is to now go for the 5842.
As I said before, its nice to see Dahua bringing better products to the portfolio that allow for great choices of camera for each environment that not only critically complement your overall setup but also importantly, each other.
HTH
Thank you for doing these, they are always very useful.
I may have missed it but what do you use to measure Lux?
Also, what are your thoughts on the IPC-HFW5842E-ZE-S2 vs the IPC-HFW7842H-Z?
The specs are almost identical, the 7842 is Wizmind 7 vs Wizmind 5, I couldn't find the diference between the two online. Also, the 7842 has 2GB RAM instead of 1GB.
@Wildcat_1 What a killer set of videos! I like the picture inset that shows what is being tested.
I have a 3 cams in the review plus a 5442. The best seems to be the 4K-X if size if foot print
and size doesn't matter.
One question, I abuse a 4K-X as a sky camera. I would like to turn off the IR shutter and force color
at night. Currently the blue from washes out all but the brightest stars. Is my line of thinking wrong?
thanks for reaching out. Will respond with a detailed answer for you in my thoughts and recommendations on this tomorrow.
