Dahua Full-color + SMD Enables Greater Safety and Convenience


HANGZHOU, China /February 25, 2020 We are always in pursuit of clearer and more colorful images not only for their eloquent appearance but also for practical reasons, since clarity and vividness usually means more information concerning safety. A lot of violent crimes are more likely to take place at night in major cities according to a 2019 report from Security Magazine. And the demand for cameras to perform in low light environment is on the rise, as shown in 2019 IHS report, growing at 20.6% CAGR from 2018 up to 2023.

Dahua Technology, a world leading video-centric smart IoT solution and service provider, introduces Full-color to Smart Motion Detection (SMD). The two technologies make a perfect match that is capable of identifying humans and vehicles in full color even in extremely low light environment. It effectively filters false alarms while retaining more useful details that can be easily cross checked though its built-in AI. The integration of these two technologies is the first of its kind in the industry, delivering unparalleled value to Dahua customers.

Dahua Technology offers two series of Full-color cameras –LED series and Non IR series – that both adopt large aperture lens that collect higher amount of absorbed light and present a more vivid and colorful image under dark environment.Dahua Technology offers two series of Full-color cameras –LED series and Non IR series – that both adopt large aperture lens that collect higher amount of absorbed light and present a more vivid and colorful image under dark environment.

Cameras of LED series are equipped with warm light that serves as a supplementary light in dark environment. The warm light also serves another purpose – to deter intruders – that can significantly reduce crimes in places like dark alleys or parks at night.

Cameras of Non IR series have no complementary light device and do not emit light like infrared cameras at night, which means it will not interfere with ongoing activities or contribute to light pollution in the environment. Also, it prevents reflections on rainy days and attraction of small insects, making it an ideal silent security guard in dim places like stores, parking lots and casinos.

SMD can easily process the visual information collected by Full-color cameras. Boasting an enhanced accuracy thanks to Full-color technology (see chart below), Dahua SMD can effectively filter false alarms triggered by irrelevant objects, such as pets, insects, leaves, branches, raindrops, lights, etc., focusing only on real threats – human and vehicle.

With advanced AI algorithms, SMD also supports quick target search from recorded videos by extracting and classifying humans and vehicles from massive video data. Users can easily trace and analyze past records using specific features such as certain colors of human and vehicle, saving huge amount of time and labor on event retrieval.

In addition, another advantage of this solution is its Alarm Visualization function, which is the capability of SMD to show clearly whether there is a human or vehicle intruding the property. Supported by real-time visual evidence, it is unlikely for users to miss or misperceive the real cause of the event.

When combined, the two technologies of Full-color and SMD stand as an excellent choice for customers with small and medium-sized projects since all practical demands are covered with a relatively low cost. Likewise, it is also suitable for distributors and channel engineering companies with general requirements for intelligence.

The following are some scenarios in which security will be significantly enhanced with the combined strengths of Full-color and SMD.

For shopping malls and supermarkets at night, the two technologies together can record all theft incidents that happened in the dark with clear features of the suspect such as hair color and clothes. More importantly, it can send real-time alarm to the user and police before the crime takes place. Anyone who approaches the door during odd hours will be automatically detected and recorded.

The same benefits also apply to residents of villas in suburban areas where it is essential to be able to detect any intruder in the dark. Once a person or a car is detected, users will receive an alarm push notification on their mobile phone so they can act and respond accordingly.

This versatile product is also qualified to guard an industrial area that is off limits, which varies from factories processing dangerous chemicals to warehouses containing valuable inventories. Due to the vastness and complicated structure of industrial parks, it is unlikely for security guards to patrol the place 24/7, especially at night. But with a security system that features Full-color and SMD, a safe and effective protection of factories at night can be achieved with less labor cost or even unmanned.

Overall, the Full-color and SMD combination is nothing less than sharp eyes plus sharp minds, which is fully capable of meeting the demands of most ordinary users at a relatively low price. With its mission of“Enabling a safer society and smarter living”, Dahua Technology will continue to focus on “Innovation, Quality and Service” to serve its partners and customers around the world.
