Any DIY enthusiast will happily tell you that Hikvision and Dahua CCTV and IP cameras are the absolute best choice for the task. Both of these security camera brands are extremely popular in Singapore, with Hikvision probably being a more sought-after choice as of now. There is no particular reason for that phenomenon, although generally speaking, Hikvision is the slightly cheaper choice out of the two options.
In any case, Hikvision is the world-leading IP camera manufacturer as of right now, and at the time of writing this (2017), it has a 17% market share. Dahua is the second one with a respectable market share of 5.5%. (Data source: IHS)
For demonstration purposes, we will be comparing the latest 4MP IP cameras, Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS, because this resolution will likely become the golden standard for home CCTV cameras in the near future.
1. ONVIF and RTSP support for Hikvision and Dahua IP Cameras
ONVIF and RTSP are probably among some features you should look for in an IP camera, especially if you have existing NVR. Hikvision as well as Dahua security IP cameras both support them just fine.
ONVIF is there to make sure the camera is compatible with equipment from third-party manufacturers, while RTSP allows software and other equipment to access your camera’s video stream. One example is the ever-popular VLC player.
2. The sensor used in the IP Cameras
Both Hikvision and Dahua IP cameras have a 1/3” Progressive Scan CMOS sensor, the most common one you can find in these type of IP cameras.
When buying a security camera, the size of the sensor is quite important. It directly influences the low light ability of a camera, and this holds true for camcorders as well. Basically, larger sensors are better suited to operate in low light conditions.
Here is how it works: by trying to cram more and more pixels into a sensor that has the same size, additional noise is created, which – in turn – reduces the details in the video. As you can see, a larger sensor effectively reduces the problem.
In any case, both Hikvision, as well as Dahua 4MP models, have true 120dB Wide Dynamic Range (WDR). This serves to further improve the video quality.
3. Minimum illumination
Minimum illumination measures the minimum amount of light required for a CCTV camera to produce a viewable image. In this category, both IP cameras are the same: both are capable of 0.01 lux and 0 lux with IR on.
4. Lenses used in Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS
Both Hikvision and Dahua security cameras allow multiple fixed lenses with different focal lengths. Hikvision has 2.8mm, 4mm and 6mm, 8mm and 12mm lenses, while Dahua uses 2.8mm, 3.6mm, and 6mm. Hikvision offers a consumer a bit more options.
5. Max bitrate of the IP Cameras
(Read here to know what is bitrate) Another difference between Hikvision vs Dahua security cameras is that Hikvision’s model has a max bitrate of 16Mbps, while the Dahua’s model has a max bitrate of 10 Mbps. However, that is a bit far from being a reason for concern. Both bitrates of up to 10 Mbps are usually more than enough for what you’re going to need.
6. Weight and dimensions
In terms of weight, both cameras are nearly identical: they are both around 0.5 kg. As for the dimension, Hikvision is 4.4” × 3.2”, while Dahua is 4.33”×3.19”. Again, these differences are minimal and noticeable only if you put one camera next to another to compare them. In practical scenarios, the difference is probably not going to matter.
7. Price of the IP Cameras
Generally, Hikvision security IP cameras tend to be slightly cheaper for some reason. However, there are different ranges of IP cameras with different features coming with totally different price ranges.
Therefore, we recommend that you make your decision based on the features each of these models provide, not price alone.
8. Resolution of the IP Cameras
Both Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS IP cameras have the resolution of 2688 x 1520 as the maximum.
9. Simultaneous video streams
Here is another difference between the brands: in this category, Dahua outperforms Hikvision, since Dahua allows for 3 simultaneous video streams at different resolutions, while Hikvision only allows for 2 streams.
Note: this is only relevant if you’re trying to do multiple simultaneous streams at different resolutions. If the resolutions are going to be of the same quality, this will not affect you in any way.
10. Frame rates
Typically, you can expect the frame rate to jump anywhere between 20 and 30 fps. Dahua’s technical sheet promises for it to never fall below 25 fps, while Hikvision runs at 20fps with the resolution of 2688×1520, 25fps with the resolutions of 1920×1080 and 1280×720. In all of the other modes, however, the minimal fps you can expect to see is 25.
11. Motion detection
Motion detection is one of the most desirable features for a reason: it helps conserve storage space, as well as saves time when reviewing the recorded footage (since you probably only want to go over the parts when something moves unexpectedly). Long story short: both models support motion detection feature.
Conclusion of comparison of Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS
While there are subtle differences between Hikvision and Dahua security IP cameras, comparing them really comes down to personal preferences. You can’t go wrong with either one of them.
