    Image comparison of 3MP Turret vs 4MP Dome at Night

    The 4MP used (DS-2CD2142FWD) is a higher end 120dB WDR model that uses a slightly better sensor, whereas the 3MP (DS-2CD2332) is a Digital WDR model that costs half as much (even when it was still a new model). The comparison between those specific 3MP and 4MP models can therefore mislead some...

    Hikvision cameras WDR

    One of the issues with Digital WDR is that it is implemented in software and therefore is prone to bugs and artifacts. I'm pretty sure that 120dB cameras are designed with a different sensor and they add DWDR on top. So even if you turn off WDR you're still taking advantage of the sensor's...

    New Hikvision 76xx firmware

    Can anyone confirm what firmware version brought the bandwidth upgrade to the DS-7608NI E2/8P or to another similar NVR?

    Hikvision cameras WDR

    As I understand it, DWDR is performed as a post-processing step by the processor chip after the image has been captured by the sensor. As with any image processing, you lose something from the image with DWDR (level of detail, noise, day vs. night etc.). The result can be something acceptable or...

    Hikvision cameras WDR

    I'm actually trying to figure it out for the Chinese cameras which would not be listed on that page (or anywhere on the "overseas" hikvision website). Basically, I need to find out if the DS-2CD2x45 cameras have 120dB WDR. I've been getting conflicting information from different sources: the...

    Hikvision cameras WDR

    Is there any way to check whether a Hikvision camera has 120dB WDR or DWDR without using the model number? Because apparently the specs listed on the website are quite often wrong

    New Hikvision 76xx firmware

    I vaguely remember reading on the forum that the DS-7608NI got an upgrade in bandwidth from 50Mbps to 80Mbps with a recent firmware. Anybody know if the DS-7608N also got a similar firmware and bandwidth upgrade? And if you are aware of the firmware for the DS-7608NI that I'm talking about (but...

    Hikvision NVR POE

    I'm not quite sure what you mean by that. Is there more of a difference than just 4/8/16POE+1 Fast Ethernet (for non-POE) vs. 1 gigabit Ethernet (for POE)? Precisely why I was trying to avoid the separate switch and get by with resetting the cameras through a Hikvision POE NVR. I would have...

    Hikvision NVR POE

    Thank you for the answer! Physical access to the NVR and hardware won't be easy in my new setup so being able to power cycle the cameras remotely is crucial. It's the main consideration for me in deciding between a POE NVR model and a non-POE with a separate switch.

    Hikvision NVR POE

    Do the Hikvision DS-76XXN/NI NVRs reset the POE ports if there is a software reboot? Is there even a manual/automatic reboot feature on these NVRs for that matter? I need to know if it's possible to power cycle the cameras through the NVR before getting one.

    PTZ 10x 2MP vs. 20x 1MP

    I'm not an expert in photography/camera theory, but I assume a shorter exposure time would be better suited for capturing moving objects in low light conditions. Would one camera have an advantage over the other in needing less exposure (assuming same sensor size and quality)?

    New arrival today, DHL is impressive

    Do you by any chance own a DS-2CD2345-I or know if there are any other differences (compared to the DS-2CD3345-I) other than metal vs. plastic mount? In particular, does the DS-2CD2345-I actually have 120dB WDR as listed on the Hikvision website? Thanks!

    PTZ 10x 2MP vs. 20x 1MP

    All else being equal, if you had to choose between a PTZ camera with a higher optical zoom or another one with a higher resolution, which would you pick? For example, 10x 2MP or 20x 1MP? And in what scenarios would you pick one over the other? The main things I can think of are: night vision...

    Huisun Cameras Hikvision Protocol

    If you own a Huisun camera (any model), could you please state the model number/type (e.g. mini dome, speed dome, bullet) and whether it supports the Hikvision protocol. I'm aware that the popular mini bullet has the protocol but I'm not 100% sure about other Huisun cameras. Thanks!

    Differences Between Hikvision 4mp DS-2CD3345-I And Hikvision 4MP DS-2CD2345-I

    I'm basing that on the assumption that the specs on the Hikvision website are correct. It has 120dB listed under WDR which corresponds to the true WDR cameras. The Chinese 4MP cameras with model numbers DS-2CD2X45 seem to be higher end ones compared to the DS-2CD3X45 and all have the same...

    Differences Between Hikvision 4mp DS-2CD3345-I And Hikvision 4MP DS-2CD2345-I

    It seems that the DS-2CD3345-I has Digital WDR whereas the DS-2CD2345-I has true 120dB WDR (better in theory).

    Hikvision NVRs Questions

    I'll sum up my questions into a single one so that hopefully I can get an answer to what ultimately matters to me: if I want to continuously record 8 cameras at the same time @1080p 15fps, are the DS-7108N-SN/P or DS-7608N-E2/8P suitable NVRs?

    What sort of compatibility problems? Serious stuff, like the cameras not detecting cameras plugged directly into the NVR's POE ports, or just minor annoyances?

    Thanks for the clips, I really appreciate it! Hikvision demos are so rare (especially for the Chinese versions) it's hard to believe Hikvision is the world's largest CCTV equipment manufacturer. The camera has EXIR, is it on in the clips or is there some other light source?

    Unfortunately, the Chinese Hikvision cameras (+DS-2CD2120F-I) are the only ones I can get with my budget (sucks). The best ones for night vision have true WDR (like the ones you suggested) but they don't come cheap. I believe there are Chinese cameras from other manufacturers with Sony sensors...
