Dahua vs Reolink vs Hikvision Varifocal Lens Camera

Hikvision has very large inventory of security cameras ranging from low end products to high end products targeted for business needs for offices, process plants, mining projects etc. Its main competitor is Dahua, with large inventory that is arguably the same as Hikvision, and most Dahua products with similar specs and features compared to Hikvision are sold cheaper.

However, if you have a lower budget, Reolink offers a similar product, slightly lower spec but cheaper than Dahua, especially when compared to Hikvision. And most varifocal motorized zoom lens cameras are tagged with more expensive price than fixed lens cameras.

Should you require varifocal motorized zoom lens cameras, consider Reolink when budget is low. However, when high end heavy duty and smart outdoor security cameras with varifocal lens, you may consider Dahua and Hikvision.

Reolink vs Dahua vs Hikvision

If the specs and features offered by Reolink rlc-522 are still not sufficient to meet your business needs, you can consider Dahua or Hikvision products with higher specs and richer features than Reolink. We take Dahua Ipc-Hdw5831r-Ze and Hikvision Ds-2cd2h85fwd-Izs as competing products, both of which have 4k resolution with varifocal lens.

Table 1 is presented to help you understand the spec comparison for Reolink rlc-522 vs Dahua Ipc-Hdw5831r-Ze comparison, while table 2 shows you spec comparison table between Reolink rlc-522 and Hikvision Ds-2cd2h85fwd-Izs.

By combining the two tables you can easily find spec comparison table for Dahua vs Hikvision.


Note that Dahua and Hikvision offer a higher resolution i.e. 4k resolution, while Reolink only goes up to 5MP @30 fps real time. Note, however, that at the same 30 fps, Dahua is only up to 3M (2304 × 1296) @ 30 fps, and Hikvision up to 5MP (2944 × 1656) @ 30 fps is the same as Reolink offers.

When resolution @ real time is your concern, Reolink rlc-522 is more preference with lower price and fit your resolution need up to 5MP @30 fps.

Camera lens

The three security cameras are equipped with varifocal lens which the view angle can be adjusted on the fly remotely by the mobile app or nvr system. Reolink’s focal length range is shorter than Dahua and Hikvision, both of the last two products feature 4x optical zoom. Zoom settings are motorized, so it’s not manual so you can customize it via mobile app or NVR system.

Hikvision Ds-2cd2h85fwd-Izs
Hikvision Ds-2cd2h85fwd-Izs 4k Outdoor turret camera

With slightly difference in focal length range, Reolink is still preference with cheaper price.

Night vision

These three products are equipped with IR LEDs for Black and White night vision. Reolink and Hikvision provide the same IR distance, while Dahua provides longer range. Hikvision is equipped with the widest maximum diaphragm compared to Dahua and Reolink, so light is captured faster to image sensor for faster processing needs.

Reolink doesn’t specify the minimum illumination spec, but Dahua and Hikvision do. With ambient light still above the minimum illumination, the camera still provides color night vision until the light drops below it and finally switches to B / W night vision.

For the needs of B / W night vision, Reolink is sufficient. However, if color night vision is required, Dahua and Hikvision can be used by increasing the ambient light around the camera so that it doesn’t drop below minimum illumination.

Actually there are few models of security cameras with color night vision such as Lorex lne8964 4k turret camera or Lorex lnz44p4b 2k ptz camera. Hikvision introduces ColorVu series cameras that offers full color 24/7, see one of its series Hikvision DS-2CD2347G1-LU ColorVu 4MP Turret.

Smart features

Up to here, Reolink Rlc-522 is adequate for the needs of your home, or small business. However, if the need for outdoor with additional smart features, Dahua and Hikvision should be considered.

    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.
