Dahua vs Reolink vs Hikvision Varifocal Lens Camera
Which one is suitable for your business need dahua vs reolink and dahua vs Hikvision varifocal lens security camera. This time I would like to compare three models of security camera with optical zoom, namely Dahua ipc-hdbw4433r zs; Reolink rlc-422; and Hikvision Ds-2cd2743g0-Izs. To make everything simple, in this article all of those complicated product numbers will be called just the name, Dahua, Reolink and Hikvision.
What is the advantage of a camera with a zoom lens? With a zoom lens, you can adjust the focal length to suit your needs without having to move forward or backward to adjust to the object to target. With a zoom lens, we can adjust the focal length without changing position. On the other hand with fixed lens you cannot do that, you only have a single view angle.
Likewise, a security camera with a varifocal lens, you can put the camera in a certain position without having to bother adjusting the required viewing angle because later you can adjust the viewing angle by controlling either through the monitor screen or via your smart-phone by zooming in / zooming out on the fly as needed.
When you want to aim at an object in the distance, small object within the frame, you cannot get the image in detail, so you need to zoom in to get the object as closer as possible to get the object details more clearly.
There are two ways to zoom in / out, namely with digital zoom and optical zoom. With a digital zoom the camera process the image by software by cropping the image within the frame and usually the result is less sharp or much noise.
Conversely, the camera with optical zoom results are very sharp and the results are as good as of the original image without zoom, because everything is done optically with complicated mechanical methods. So that’s why cameras with optical zoom are tagged at a price that is much more expensive than cameras that are not equipped with optical zoom.
Dahua vs Reolink vs Hikvision
To make long writing short, let’s focus on the three camera products with varifocal lens by comparing dahua vs reolink and dahua vs Hikvision. please refer to table 1 representing spec comparison between dahua and reolink, table 2 representing spec comparison between dahua and hikvision.
All the three products offer the same 4MP resolution, however at different frame rate per second (fps) speed. Dahua offers 4MP @20 fps, lower frame rate than both Reolink and Hikvision that are designed with 4MP @30 fps real time speed.
Dahua offers range of varifocal lens with 5x optical motorized zoom. On the other hand both Reolink and Hikvision come with the same range of focal length with 4x optical motorized zoom.
The security camera must still be able to function well both day and night. Almost all cameras support night vision while still being able to view and record in black and white when night falls with the activation of IR LEDs with a certain range. 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.
Dahua is superior compared with the other two products reolink and hikvision regarding range of infrared light.
