Hardware
Both the 4MP Dahua and Hikvision have the most common sensor, 1/3″ progressive scan CMOS sensor.
The size of the sensor has a huge bearing on the low light ability of a camera. The larger the sensor, the greater its ability to gather light and so do well in low light conditions. But as you cram in more and more pixels into the same size sensor, they get smaller and smaller, which adds noise. Noise is the bane of low light video and reduces the detail that you can get out of your video.
So while security camera manufacturers have pushed pixel count from 3MP to 4MP, they have not increased the sensor size. However both the Hikvision and Dahua 4MP models have true 120dB Wide Dynamic Range (WDR) to help improve video quality. Both cameras can do a minimum illumination of 0.01 lux and 0 lux with IR on. Both cameras have fixed lenses available at different focal lengths. Hikvision does 4mm and 6mm, whereas Dahua offers more options with 2.8mm, 3.6mm and 6mm.
Protocol support & Bitrate
Both cameras able to support ONVIF and RTSP protocol, these are two most important features for IP camera. ONVIF ensures that your camera will work with standards-compliant equipment from 3rd party manufacturers. RTSP allows even non-ONVIF equipment (such as software) to access the security camera’s video stream. Hikvision 2CD2042WD-I has a max bitrate of 16Mbps vs. the 10 Mbps of the Dahua IPC-HFW4421S. Usually, 6Mbps is good enough for most of case. Dahua has is the ability to provide three simultaneous video streams at different resolutions, whereas the Hikvision can do only two different resolution simultaneously.
Motion Detection
Both cameras support basic motion detection, as well as advanced motion detection techniques. But the Dahua has the advantage here with face detection, abandoned object and missing object detection.
A major reason for the selection of both these brands is their price option and the lens option that sets them apart from the rest in the market.
However, Dahua camera installation in Lahore the main question is which brand out of these two is better and how can we decide if Dahua camera installation in Lahore is suitable as compared to Hikvision camera installation in Lahore or vice versa.
