Capture the Whole Scene with Dahua Full-color Dual Lens 180° Panoramic Cameras

Imagine walking on a busy street at night when suddenly you heard loud shouting followed by a large commotion. An incident has just happened right at the corner of your eye. You probably heard some noise and saw bits and pieces. Nevertheless, chances are you would not be able to recall every detail of what happened based on your line of sight and by just plain memory. It was dark after all.

This is basically the same dilemma many establishments face nowadays with traditional security surveillance. There might be cameras in the area, but not enough to cover large scenarios. Large areas typically require more cameras, leading to high deployment costs that many of us cannot afford. Under dark conditions or during nighttime, images captured by traditional cameras are normally just dull black and white footage; ‘recorded with a potato’ as some would say. Also, these devices are typically not equipped with a microphone or speaker, meaning Two-way Talk is simply impossible during an event.

In places such as squares, parking lots, and hallways where full coverage with absolutely no blind spots is imperative, installing a panoramic camera is a no-brainer. A panoramic camera, as its name suggests, is a fixed camera that can provide wide-area coverage, making it an excellent alternative to the daunting installation of multiple cameras just to cover a large scene.

In terms of features and functionalities, the Dahua Full-color Dual Lens 180° Panoramic PTZ & IPC devices tick all the boxes of an efficient security solution that can address the abovementioned monitoring challenges. Let’s check out below what they have to offer.

Seamless Stitching & Advanced Image Fusion Technology

The Dahua Full-color Dual Lens 180° Panoramic PTZ & IPC devices are equipped with dual sensors that deliver a 180-degree field of view. Now, how do these cameras generate a single 180° panoramic image?

First, the right and left lenses capture an image. Next, using standardized image correction technology, the camera calculates the feature values of the left and right images to avoid warping and pixel loss. Lastly, the Dahua advanced pixel-level metadata fusion algorithm enables seamless splicing of the image. The result: a seamless 180° wide-angle image of a large scene using just one camera!

Full-color Technology

For better image performance, both panoramic PTZ and IPC devices utilize Dahua’s very own Full-color technology. Each camera lens supports an F1.0 aperture to collect more light. Compared to the F1.6 aperture, the light intake of the F1.0 aperture is 3 times larger, providing a significantly brighter and clearer color image of the monitored scene even in dark environments or during nighttime. In addition, underneath the lenses are two warm lights, which have a lesser effect on the human eyes, and help reduce light pollution in the monitored area.


One cool feature of the panoramic IPC is EPTZ (electronic pan, tilt, and zoom) which uses digital zoom technology to provide real PTZ-like features on a fixed non-PTZ camera. It provides a panoramic image for a wider view of the scene, as well as sub-images that focus on specific areas or targets. It offers five different layouts or modes. Each mode includes a wide-angle view that can hold 1, 3, or 5 different sub-images for a more convenient monitoring experience.

Independent Mode and Smart Linkage Mode

Both panoramic and detailed views support AI functions for the panoramic PTZ camera. Two cameras can be independently deployed in different directions to cover wider areas. What’s more, the smart linkage mode can be integrated with IVS, enabling the panoramic camera to capture the whole view of the scene while the speed dome camera zooms in to acquire details when alarms are triggered, thus increasing safety in the monitored area.

Two-way Talk

This Dahua panoramic camera is also equipped with a built-in microphone and speaker that supports the Two-way Talk function. When connected to the network, users can communicate through the camera anytime, anywhere. How convenient is that?

AI Functions

These cameras will not be complete without AI functions. The Perimeter Protection utilizes a deep learning algorithm to accurately identify targets with high accuracy. It supports up to 6 types of rules and can provide real-time alarms and push notifications via the mobile app. The IPC has a People Counting function that can accurately calculate the real-time statistics of people entering and leaving a certain area, enabling timely dispersion measures to avoid overcrowding and generating traffic flow and valuable data that can aid business analysis. It also includes Smart Motion Detection (SMD) that can accurately detect targets in the monitored scene by filtering out nuisance objects like leaves, animals, headlights, etc.

Capturing the entire scene in one color image is possible with just a single camera. The Dahua Full-color Dual Lens 180° Panoramic PTZ & IPC devices serve as an intelligent solution that provides wide-area monitoring coverage. A larger scene can be constantly monitored with just one camera, saving time and installation costs for installers and end users. Its built-in mic and speaker enable users to communicate to the detected target in the scene anywhere and anytime. And thanks to Full-color technology, this intelligent panoramic camera can provide clear color images even at night, which is essential in providing 24/7 continuous monitoring in large application scenarios such as squares, hallways, and parking lots.
