    Ethics of reviewing a camera provided free without disclosing it was received free

    Good for you @Adamsdaddy, unfortunately, there are a lot of fake / paid reviews on Amazon. The request to upgrade the review to 5 stars is unethical as well.

    What are the best color low-light cameras? What should IPVM include in our test?

    I'll let Ethan answer model specifics but we normalize exposure to 1/30s to minimize blurring of moving objects in testing.

    What are the best color low-light cameras? What should IPVM include in our test?

    Thanks for the feedback. Ethan, who leads our video surveillance testing, passed along the following: Domes have historically been the most popular models installers use, which is the main reason we use them so much. In shootouts, we often prefer to go with domes for standardization, but we're...

    New ColorVu cameras

    We found the same pattern. While the camera(s) are spec'd for 30 meters / 100 feet, the camera has problems in 'complete darkness' at longer ranges. We measured the lux levels at various distances which underscored those challenges:

    What are the best color low-light cameras? What should IPVM include in our test?

    We (IPVM) are doing a color low-light shootout. We have a list of 19 models already from various manufacturers. On the Dahua side, which is popular here, Dahua USA reps have recommended the N45EM63, a 1/1.8" 4MP "Night Color" model. What do you think is best and would like to include? Please...

    NX witness V4.0 is released

    Just use Blue Iris. I am kidding, sort of, but genuinely curious, given the affinity for Blue Iris here, how do you see NX Witness comparing to Blue Iris?

    ONVIF suspends Hikvision and Dahua

    Blue Iris simply violates ONVIF's terms but ONVIF is lax generally in enforcement, so probably not an issue for you. I think, as a user, you should be fine but nobody can really tell how the US / China conflict will evolve and how it will impact various industries.

    ONVIF suspends Hikvision and Dahua

    Roughly speaking, they should work as they have before. Keep in mind, Blue Iris has never been officially ONVIF conformant. Blue Iris claims to support ONVIF but it is unauthorized and untested by ONVIF. As such, from the perspective of making Dahua and Hikvision work with ONVIF, unless Dahua...

    US blacklists Chinese surveillance companies over human rights abuses

    I agree with you that 'use' should not be a basis for sanctions. However, the issue withDahua and Hikvision is that they have more than a billion dollars of direct contracts with the China government to supply, deploy and operate these systems. In your analogy, this would be like Toyota going to...

    Hikvision and Dahua Blacklisting

    The way the entity list / 'blacklisting' works is that if a US company wants to sell technology to Dahua or Hikvision (think Intel, NVIDIA, Western Digital, etc.), they need to get a license which is typically not approved, ergo it's 'blacklisted'. However, Dahua or Hikvision are still free to...

    US blacklists Chinese surveillance companies over human rights abuses

    No, this is new. There were media reports earlier in the year that the US government was planning this but today was when it actually was announced/implemented.

    US blacklists Chinese surveillance companies over human rights abuses

    Our (IPVM) post: Hikvision And Dahua Sanctioned For Human Rights Abuses For US people buying Dahua and Hikvision, they can still buy Dahua and Hikvision. The transactions carry a 'red flag' but are not banned. There will be indirect impacts as various partnerships will be reevaluated but I...

    Recognition, License Plate Reading aka AI

    Usually, LPR cameras are bullet or box format to better accommodate the lensing and IR illuminators to optimize capture/recognition performance. There might be some that are bullets, that I don't know.

    Recognition, License Plate Reading aka AI

    Facial recognition is somewhat similar structurally. In practice, there are 2 parts - capturing a face and then recognizing a face. Some cameras can capture a face (i.e., 'know' and mark where a face is), a smaller number can actually capture and recognize a face (i.e., attempt to match a...

    Recognition, License Plate Reading aka AI

    For license plates, there are 2 fundamental elements: - the ability to capture the license plates, that is to see the characters clearly in various conditions, dark, headlights, angles, etc. (i.e. a human can now see the plate's characters is ABC-123) - the ability to recognize what all the...

    New ColorVu cameras

    The default shutter speed for ColorVu is 1/12s. Can you check if that is what you are using? You can see blur in the second video Do you have a lux meter to check the exact light levels? You say 'complete darkness' and I am sure it's dark but for cameras, it makes a difference if it is 0.2...

    Are Shipping costs from China to the US going to rise this fall?

    Can you elaborate on that? What is the 'cheap slow way'? How did it destroy retail even in China?

    Dahua DORI vs real world ?

    DORI is an antiquated concept and rarely used professionally these days. I'd just ignore it.

    Dahua DORI vs real world ?

    If I am reading Dahua's spec sheet for that camera correctly, their 'identify' level maps out to ~65ppf which will, in good lighting conditions, allow identifying a person. If you understand PPF, and you do, it is probably clearer/easier to communicate using the PPF number you desire rather...

    Is this Peak IP Camera?

    Good question. Product improvement is shifting currently to video analytics and cloud management. There is only so much value in increasing resolution for most cameras so manufacturers are shifting to compete on software (AI, VSaaS). Agreed about product pricing being steady or rising, part of...

    US Government Ban of Dahua, Hikvision, Huawei Takes Effect Now

    Tariffs might become an issue for the DIY/Home markets but the (separate) ban effect is really focused at government and those users that get funding from the government. DIY/Home is quite far from those areas. There might be some sort of worse case scenario where the impact of the ban and...

    US Government Ban of Dahua, Hikvision, Huawei Takes Effect Now

    The 'news' is (1) that it has officially 'taken effect'. When it was passed last year there was a year before it went 'live' and there was hope among Hikvision partners that this would be reversed beforehand. (2) The rules that were released include 'essential components' of equipment, which...

    Amcrest IP2M-841 firmware going backwards?

    We had the same question when we examined this last week. Interestingly, the Dahua patched firmware is 2.622.0000000.7.R but the Amcrest patched one is V2.420.AC00.18.R. Certainly, any company can choose any method for how it increments/enumerates firmware but what Amcrest did here is strange.

    camera spreadsheet

    We (IPVM) have aCamera Finder that might help. It's freemium, part of the results are members only, part is public. It might help for scanning through different options. We do keep it up to date and we add cameras daily for both that and our Camera Calculator.
