Reolink vs Dahua vs Hikvision Security Camera Systems

When folks ask question which one is better, Reolink, Dahua or Hikvision? Read the following article to understand the three security camera systems.

Reolink, Dahua or Hikvision

The question above is a common one, because the three vendors produce various kinds of security camera devices, including recording units and accessories. However, in general the products released by Reolink are relatively cheaper than Dahua and Hikvision with the same / similar specs and features.

Dahua and Hikvision

Both Dahua and Hikvision were founded in 2001 and both are from China. Both Dahua and Hikvision have dominated the security camera market in large number of countries worldwide. Dahua majority shares are owned by a Chinese husband and wife and partly controlled by the China government. 

Unlike Dahua, Hikvision is a state-owned manufacturer Chinese government. However, because the USA considers that the Chinese government uses Hikvision camera security systems for monitoring purposes in human rights violations in Xinjiang, Hikvision has been banned by the USA since Jan 2019.

No wonder you will have difficulty getting original products from Hikvision and Dahua in the market, except for OEM products.

When to use Reolink, Dahua or Hikvision? Of course this is a general question because it depends on your business needs regarding security systems. We take a look at some of the flagship products of these three vendors.

Security camera

We will take a series of flagship cameras from each of these vendors that can represent the latest technology, at least camera technology that can detect human / vehicle, or AI (artificial intelligent) technology with sophisticated algorithms to be able to recognize faces captured by the camera and compare them with facial data in the system. .

Dahua N85CB5Z

This product is one of the newest products released by Dahua which is a 4k resolution bullet model security camera with varifocal lens and is equipped with e-poe technology allowing data transmission up to 800m via UTP or coaxial cable.

    You’re comparing garbage like Reolink in the sub $100 range to 4K cameras with a lot more features in the over $250 range.
    A bit of a ridiculous comparison. You are not even comparing the same feature set. There is no metion of iFrame rates or anything that is actually useful to serious surveillance.
    As a note, the Reolink RLC-822, the 4K version, has exactly the same flaws, particularly with night vision.
    I own a REOlink RLC-520. Night vision is complete garbage and limited to 12FPS in B/W and it switches to B/W mode when there is still over about 30lux brightness. The 12FPS is confirmed by Reolink tech support. Colour night vision is impossible. Anything under 15lux gives a compeltely black image.
    Additionally, due to the ridiculously low iFrame rate, that is not user adjustable, B/W night vision in particular is a blurry mess of ghosting and unusable footage. Face identification at anything over 15 feet is virtually impossible and not legally usable.

      What is taken into consideration is the available budget. If your budget is under $ 100 what camera features do you get compared to other feature-rich and high-spec products that may cost two or three fold the price of a low-priced product? Selecting the product with features and specs that suite to your needs, that is the point I think.
