Dahua Technology is a Chinese video surveillance products provider, with 22 branch offices around the world. The company achieved “the second highest market share of the of global video surveillance equipment market in 2015” and is a well-known brand of CCTV Cameras, Video Recorders, Alarms, Locks, Sensors, among other security devices.
Dahua Technology offers a wide range of products to cover the needs of different environments such as residences, stores, industries and other important facilities. The company invests more than 10% of their sales revenue in Research and Development per year, aiming for the constant improvement of their technologies. In the year 2015, Dahua Technology has revenue of about CNY10.1 Billion (about US$1.57 billion).
Due to the camera’s all-metal construction, it feels very solid and no doubt will be very durable. It’s compact in size, measuring just over 10cm (4″) across the base, and 9cm (3.5″) tall from base to dome.
There is a decent amount of detail due to the sensor, and there are comprehensive controls such as brightness, contrast and saturation in order to fine tune the picture, however, beyond this, the quality is disappointing. There is a distinct lack of sharpness, partly due to the optics not being up to the task of resolving fine detail, and partly due to compression artefacts. The image is muddy and everything beyond a metre or so looks slightly out of focus. The maximum H.264 bitrate that the camera can produce is 8192 Kbps, which is rather meagre for a 3 MP 20fps video stream, and results in noticeable image degradation.
There are four different lens options available for this camera: 2.8mm, 3.6mm, 6mm and 8mm – here we are testing the 2.8mm option, which gives the most wide-angle view, however, there is significant barrel distortion, especially towards the edges of the frame, resulting in a significant fish-eye effect. This will no doubt be less severe with the longer focal length lenses.
- Compact size
- The good feature set, including night-vision and a built-in microphone
- Well-designed web interface that is compatible with OS X web browsers
These are the best Dahua CCTV listed below:
DAHUA 2MP MINI PTZ DOME CAMERA
For those users who don’t want to pay a thousand dollars on an IP PTZ camera, you can look at the Dahua DS42212SN-HN (the new model is SD42212T-HN), which is a mini PTZ camera offers less powerful 12x optical zoom capability. Since the total power consumption to this Mini PTZ camera is not very high, it can be powered either the included power supply or a PoE+ injector/PoE switch.
Though this camera belongs to Dahua affordable Eco-savvy series, and it doesn’t include infrared illuminators, this doesn’t mean it’s a low-end camera. In Carl’s test, Dahua SD42212SN-HN has much better low light capability can compete Hikvision mini IR bullet camera.
Carl’s review to Dahua SD42212SN-HN Camera, as an affordable PTZ camera, it offers high image quality, true colour reproduction image and decent low light performance, it’s definitely the right one for those residential users who looking for a small PTZ camera to secure their outdoor areas.
The pros are can upload video footage to FTP remote server, or onboard microSDHC/TF card (not included), it’s an inexpensive IP PTZ camera with very good low light performance, video capturing can support [email protected] or [email protected]/60fps.
However, when it tested the camera, it would occasionally encounter video delay that lasted up to 5 seconds while using the PTZ controls. Additionally, it’s called mini, but it’s actually a regular size camera if comparing with a Dahua mini dome camera.
DAHUA 3MP MINI BULLET NETWORK CAMERA IPC-HFW4300S
Dahua Eco-Savy series IP cameras boast saving power consumption to be eco-friendly. By utilizing the low consumption power hardware design, the camera’s total power consumption is less than 5 watt, while regular 2MP mini bullet IR network camera e.g. IPC-HFW3200S (3MP cameras has been upgraded to 4MP, the latest model for this camera is IPC-HFW4421S) consumes approximate 6-watt power.
IPC-HFW4300S 3-megapixel bullet camera utilizes a 1/3 inch type progressive scan CMOS image sensor from ON-Semiconductor (formerly Aptina). It’s capable of shooting video with the resolution either in [email protected] (2048*1536) or [email protected](1920*1080) mode. It comes with a standard fixed 3.6mm lens can provide a wide viewing angle, supporting DWDR and 3DNR function. This camera can be powered by DC12V or PoE (IEEE802.3af).
Compared with the IPC-HFW3300C, this camera is a very compact and doesn’t support the rich feature. It doesn’t have audio I/O and alarm I/O, no microSDHC/TF card slot for onboard video recording. As replacing the Sony Exmor CMOS image sensor, this camera can output crisp and vivid colour highly detailed image. Carl commented that Sony Exmor sensor was able to capture a good image with the right colour saturation and contrast, but compromised detail.
Separating Dahua cameras from other brands is the Dahua camera’s web interface offers image profiles. Profiles allow you set different options for day & night video monitoring, you even can set a time when the camera should switch to a different profile. Scheduled profile switching is very handy to installers.
Carl reviewed, Dahua IPC-HFW4300S provides good value for your money, it offered 3MP/20fps or 1080P/30fps video shooting capability, while image quality was awesome. However, it also had shortcomings, for instance, the image might not have the contrast of other cameras in this segment like the Hikvision mini bullet IR camera but the tradeoff was better detail in the shadows.
DAHUA OUTDOOR 1080P IR MINI DOME CAMERA IPC-HDBW2200E
After went through the installation and test, Carl concluded Dahua IPC-HDBW2200E (discontinued, the latest model is IPC-HDBW4220E) was good value for the money, it delivered a crisp image with 30FPS[email protected] resolution as it advertised. Unlike Hikvision vandal-proof cameras, this camera didn’t have IR halo issue. The setback was it only supports 2-axis adjustment limited camera’s placement in some areas.
Dahua followed the footprints of Hikvision, Dahua released the ConfigTool to help users to search and config IP cameras at the initial stage. Enter the default IP address (192.168.1.108), you can access its web interface.
The below image is a daytime shot in Car’s driveway. The colour accuracy, contrast, detail is very impressive. Carl liked 3.6mm lens because it offered the right viewing angle, while 2.8mm lens was a little too wide would cause a distortion on the edge of the image, the 4mm might be too narrow.
DAHUA OUTDOOR 3MP ZOOM DOME CAMERA IPC-HDBW2300R-Z
Dahua IPC-HDBW2300R-Z is the smallest size optical zoom dome camera that Carl had been reviewed. It’s equipped with a 2.8mm-12mm motorized zoom lens which can provide maximum 4x optical zoom capability. This camera still adopts ON-Semi CMOS image sensor, has a day/night ICR filter built-in to provide you crisp image in the daytime and the decent low light performance at night.
Installation of this dome camera is straightforward; it offers DC12V and PoE power supply options. It’s also a vandal-proof dome camera which protects it from vandalism. By leveraging the motorized zoom lens, the camera can adjust the optical zoom and auto-focus to obtain a clear view, eliminating the hassle to adjust the focal length manually.
Intending to solve the IR bleed problem, the include Infrared array LEDs are located further away from the lens. Carl wrote this was a genius idea.
In this review, Carl mentioned how to set DDNS up for Dahua IP cameras. Using the DDNS, users can remotely access the camera’s web interface even the camera uses dynamic IP address. DDNS also converts IP address to easily remember domain name.
Since it can automatically zoom in and auto-focus, this camera is super easy to install, as it uses ON-Semi CMOS image sensor, the image quality superb, clear and has good clarity. Moreover, the IR LED design is so clever; Carl liked this dome camera very much. This camera is also discontinued; you can find the upgraded model – IPC-HDBW5431R-Z.
HDCVI CCTV Cameras from Dahua Technology
HDCVI, High Definition Composite Video Interface is actually an invention brought by Dahua Technologies, which they have allowed to be open to other manufacturers. HDCVI CCTV Cameras are considered as a revolution in the world of video surveillance.
This technology is a new method of video signal transmission via coaxial cables which allows a better resolution. It is a high quality yet cheaper option than Network IP cameras and a better alternative to the same price analogue CCTV cameras, which deliver a lower image quality. Systems with HDCVI technology are able to transmit audio, video, and control through the same cable, while regular analogue CCTV Cameras require different cables for each signal.
Dahua Technology offers several types of cameras under this product segment, divided into several categories: Lite, Pro, Ultra, and Multi-Sensor Series. Lite Series groups 1 to 4 MP cameras with different characteristics regarding shape, such as Bullet, Dome, and Eyeball cameras. Also, varifocal and waterproof models are available.
Pro Series include cameras with 2MP to 4MP resolutions and similar shapes as those mentioned above. The Ultra Series goes up to 8MP. Some models in this series comprise Starlight technology for low-light conditions, such as the MP IR Varifocal Starlight HDCVI Bullet CCTV Camera.
Multi-Sensor series is represented by the 3 x 2 MP Multi-Sensor 180° Panoramic HDCVI IR Bullet CCTV Camera, which includes three 3.6 mm lenses, delivering a 180° Panoramic Output; also offers 2D and 3D Noise Reduction for a sharper image.
Network IP Cameras from Dahua Technology
These types of CCTV cameras work wirelessly via an IP Network, which means it is a higher and more expensive technology. Dahua Technology has a wide offer in this category of IP cameras, including Lite, Wi-Fi, Multi-Sensor, Ultra Smart, Eco-savvy 3.0, Consumer and Panoramic Series. Lite Series cameras range from 1 to 4 MP in several shapes (dome, bullet, and eyeball) and some of them come in the “mini” size version of each shape.
Wi-Fi Series includes cameras with resolutions from 1.3 to 3 MP able to work with both Wi-Fi and Ethernet. Multi-Sensor Series cameras are mainly by the DH-PSD81602N-A360 and the DH-IPC-PFW8601N-H-A180 models. The first one offers a 360° panoramic view with 8 sensors of 2MP each while the second one is capable of delivering a 180° view and includes Ultra-low-light sensitivity for dark conditions. Ultra Smart Series range from 1.3 to 12 MP in several shapes (box, bullet, dome, and pinhole) and some models offer the following features:
- Face Detection
- Tripwire Detection
- Intrusion Detection
- Scene Change Detection
Eco-savvy 3.0 Series groups several models of cameras with resolutions ranging from 2 to 8 MP, also with smart detection functions such as those mentioned above as well as the Starlight technology for better footage in low-light conditions. The Consumer Series goes from 1 to 3 MP in resolution in most sizes and shapes.
Panoramic Series cameras are divided into two groups: Fish Eye and Multi-Sensor (just like the ones described above). Fish Eye cameras are vandal proof and some models include a built-in microphone, all embedded in a different design that brings many benefits to the user.
PTZ Cameras from Dahua Technology
PTZ cameras are devices available for both HDCVI Camera and Network IP Camera. PTZ (Pan-Tilt-Zoom) refers to the feature of automatic motion/thermal detection of the camera, which is capable of changing its zoom control and direction towards an identified target. Dahua Technology offers several types of cameras in this category with very similar characteristics to the ones described above for both Network and HDCVI cameras.
Optical zoom and tracking features are the main characteristics of this specific type of device, which allow the possibility of monitoring certain objectives by detecting changes in the scenes covered and then zooming in the area where the change was perceived. All in all, Dahua Technology works hard in order to offer superior quality products with great features that improve security systems in all kinds of environment.
