Hikvision Product Comparison

Thanks ! For some reason my camera seems to be missing. DS-2CD2342WD-I It is a 4PM dome camera with IR.
 
Hello there - Is there any comparison available for these Hikvision ColorVu cameras?



Both have the same senor. Can someone comment which one has a better tech spec?

Thanks,
JT
They are the same camera. Just different lens sizes.
note they are not ip cameras if that is what you are looking for.

I found good price analog cameras:



maybe someone try it?

I agree this information would be extremely useful, but I can't find a single camera in the spreadsheet, only NVRs, and I searched all tabs. What am I missing here?

Confused with Hikvision model numbers? And features included in specific cameras? Please have a look at this easy-to-read spreadsheet. It'll also give you the prices of cameras from three reputable sellers, it is safe to order from them. In this thread, you can also ask about differences of the models.


>> Hikvision Product Comparison - Google Sheets
(both cameras and NVRs now compared!)


Important thing to note:
If you purchase a Hikvision camera / NVR from Aliexpress, you should not upgrade the firmware. If you upgrade it, the user interface will be in Chinese only. Despite there are some solutions to this issue, it's better not to upgrade the firmware if you are unsure.

I think the sheet is broken.... there is nothing there.
 
it appears that spreadsheet allows anonymous edits, and people have been scribbling all over it.

i'm looking at the version history, see if I can find an older version thats still useful but the file seems really blown up. my normally quite snappy fast computer is crawling trying to load the history of that google sheet.
 
wow, had to go back to september 2015 to find one that looked un-pooped on. I was going to restore it and try to lock it down, but thats so old, not sure its worth it.
 
Decisions, decisions. I think the 4MP hybrid on the 1/1.8 would be the best, but for 5 bucks less I can get a 4K. Im sure you can turn the strobe option off and have just IR?
$170
(ebay)
$165
(Andy can hook me up)

4K cameras have tiny pixels, which means much weaker night vision, many cameras try and compensate for that by having much brighter IR illuminators, but those attract spiders who make webs all over your lens every night.

This post has been very helpful with my development. I have just downloaded the latest SDK and have noticed there is a new Login function "
NET_DVR_Login_V40".

I am trying to use it but unfortunately I keep getting error 17, Parameter invalid.

I have spent a long time and I cannot see the error of my way maybe someone can check my wrapper and ensure that it is correct and if they can use the new SDK function correctly. I have a feeling it may be in my wrapper struct declaration.

Thanks in advance.

Im struggling to understand what does "SL" and "(ef)" mean in model specifications. I understand the LI, LU etc specs but not the above that are after the / in model number
 
Hello,
im new here. And I have a question. Does anyone know the real distance between these two models please?

DS-2CD2T87G2-L model from 2021 with verry old firmware. If it is possible to update to the firmware from 2024, how please?
and
DS-2CD2T87G2-L(C) - actualy model with current FW from 2024

The model without the letter "C" costs 1x less than the model with the C mark. Which is strange.

Thank you very much for your reply

My understanding, which hopefully others will confirm, is that the (C) suffix indicates a hardware variant, driven most likely by the supply chain issues that have existed for several years. An implication is that a variant of firmware is consequently needed.

Actual model (C) are using big 1/1.2" image sensor.
Check is the same with old variant in spec sheet?
it can be smaller one (1/1.8"), which give worse night performance..
