Dahua Technology's HDCVI technology can simultaneously transmit 3 signals (audio, video, data) over one coaxial cable. HDCVI cameras offer high-resolution images, sometimes support an audio input or an integrated microphone and communicate with the HDCVI DVR via control signals. Please use our filter if you are looking for cameras with audio input or microphone.
Dahua Technology's HDCVI technology supports resolutions up to 4K UHD. The higher resolution allows more details to be seen, so the information content of the images increases. The distance of the camera to the monitored area plays a major role in selecting the appropriate resolution. If you place your camera at great heights, or if you use it to survey larger areas, then a high resolution offers you the possibility of recognising details at a greater distance when using digital zoom.
The frame rate, specified in "fps", is an important component in recording, as a smooth image reproduction provides more usable information. A higher frame rate ensures that even fast objects can be easily recognised in the recording.
With the help of numerous junction boxes, extensions, hanging mount adapters and mounting boxes, you have a wide range of options to install your cameras safely even in difficult locations. By using baluns, you can operate your analogue cameras over existing network cables (UTP CAT5e/6) even without existing coaxial cables, saving you time and labour costs.
Full-colour cameras are particularly suitable for applications where colour information such as vehicle and clothing colour is important even in very low light (e.g. only outdoor lighting). Or to put it simply, full colour is always the right choice when you want to see colour images even in very low light (as an alternative to IR mode). In our shop you will find a wide range of Full-Color cameras.
The IoT cameras (Internet of Things) offer the possibility to measure temperature and relative humidity at the place of use through additional sensors. This makes them well suited for use in server rooms or greenhouses, for example.
Wide Dynamic Range
Wide Dynamic Range (WDR) is a technique for balancing light and dark areas in the image. Especially in scenes with very high contrast, the WDR function ensures that an even exposure takes place. In this way, even people standing in front of a light source, such as a window or a spotlight, can be easily recognised.
The analogue cameras from Dahua are available in white and black.
Surveillance cameras come in a variety of designs. The best known of these are the "bullet" cameras, which resemble a tube due to their design. These cameras are preferred for outdoor use. Dome and eyeball cameras often have round and very compact housings. In the case of "dome" cameras, the lens of the camera is protected under a glass dome from external influences such as weather or vandalism. When buying, look for the IK10 rating, these cameras are vandalism-proof! Thanks to their very short focal length, fisheye cameras have the special ability to create a very wide angle of view. With the help of a suitable recorder that supports "Fisheye Dewarp", you have the possibility to display several image sections of the fisheye camera undistorted. Pinhole cameras are used in places where a standard camera would be immediately detected. Due to their size, they are easy to install and can be hidden in their surroundings. PTZ cameras (pan-tilt-zoom) have the function of being controlled remotely. This allows you to quickly change the camera's field of view or follow events.
With our filters you can quickly find the resolution you need. High resolution provides a more detailed image and ensures that even at high digital zoom, many details such as number plates, faces and more, remain recognizable.
IR LED Illumination distance
A high illumination distance of the infrared LEDs ensures that even larger areas are illuminated for the camera at night. The infrared light can only be seen by the cameras and offers the cameras the possibility to produce a black and white image even in complete darkness..
Choose between a motorised lens where you can easily adjust and change the focal length yourself, or a fixed lens with a fixed focal length for use in places where it is not necessary to mechanically change the angle of view.
Use the audio input of your HDCVI camera to connect a compatible microphone. Often the quality of the built-in microphone is not sufficient, or the camera is placed in a location (e.g. near a TV or ventilation) where audio recordings are rendered unusable. By connecting a microphone, you can influence and improve the recording location and quality yourself, e.g. by using an omni-directional microphone with noise reduction.
Many HDCVI cameras already have a built-in microphone and, thanks to Dahua's HDCVI technology, can transmit the audio signal over the existing coaxial cable.
Via the alarm input of your HDCVI camera, you can connect devices such as sensors or infra-red motion detectors that have the ability to trigger your camera to perform an action, e.g. start a recording, when motion is detected.
Devices such as acoustic sirens or warning and alarm lights can be triggered directly by the camera in the event of an alarm. To do this, connect your devices directly to the alarm output of your camera.
