Dahua Technology Creates a More Connected World with HDCVI-IoT

Dahua led the industry to introduce HDCVI Technology. Throughout the years, it continues to enhance the technology leadership by bringing state of the art performance in terms of resolution, light sensitivity, intelligence and usability to the HDCVI community. In April of 2017, Dahua unveiled HDCVI 4.0 era to the world, followed by the launch of HDCVI-4K, the first key technology in its technology framework. Now it is the debut of HDCVI-IoT.

What’s HDCVI-IoT

                                                                              HDCVI-IoT Layout

While still a relatively new concept unfamiliar to most people, IoT (Internet of Things) has already brought great convenience to our daily life, ranging from smart lighting and keyless entry access control system to automatic driving, all of which are free from manual control and operate on their own. With intelligent perception and recognition technology, it is possible to directly exchange information between things, meaning IoT does not rely on internet connectivity nor human intervention to operate properly. In many situations, IoT makes things respond more reliably and in a more real time manner than internet remote control systems. In fact, IoT has pervaded every aspect of today’s life, changing the industry, agriculture, construction, energy, medical, retail, consumer electronics and many other industries.

Developed by Dahua patented technology, HDCVI is the world’s leading HD-over-coax technology that can simultaneously transmit audio & video, power & control signals through the existing analog infrastructure. The product line now covers front-end cameras with resolution up to 4K as well as a full range of back-end storage products. Boasting stability and excellent quality image, the product has already been widely used in all industries around the world.

HDCVI HD-over-coaxial technology features a simultaneous transmission of audio and video unaffected by long distance, and can operate on its own without network, which coincide with requirements of IoT technology: real-time-ness, off-line local control, high security performance, etc. Based on which, Dahua, being the first, proposed “HDCVI-IoT” technology that combined existing HDCVI high security video surveillance with IoT consisted of more intelligent off-line monitoring and control system. One of the core technologies of IoT is the integration of sensors and transceivers on each device, rendering intelligence to the device to perceive and judge. For instance, if someone breaks into a high security area, a conventional camera can only re-play the video record of the time while a Motion Eye camera of HDCVI-IoT series, through the built-in high-performance PIR (Passive Infra-Red) sensor in collaboration with built-in video analytics, can accurately filter situations like a dog moving around and natural environment changes such as moving tree leaves, and then trigger the alarm in real time while the video is available to verify the alarm. In short, the technology as well as the function of video surveillance is upgraded from record and replay to reason and respond.

HDCVI-IoT Can Be Applied to Agricultural Production, Storage, Culinary Area, Library…

Features and Applications of LinCa Series

HDCVI-IoT technology works in four steps, to “sense” and “pass” information with the front-end camera; to “calculate” and “control” the scenario with the back-end storage. For small and medium off-line local IoT applications, Dahua has developed LinCa series of front-end products, including the 2Megapixel Camera LC1220T-TH with a built-in high precision temperature and humidity sensor, the 2Megapixel Camera LC1200SL-W with built-in wireless gateway, both supported by back-end storage with built in intelligent control algorithm and easy access to Ethernet.
LC1220T-TH
In many circumstances the data of temperature and humidity requires real time attention, such as the storage of food, medicine and chemicals. In which cases, we need cameras to monitor how the goods are handled from afar, but we also need to maintain the temperature and humidity of the warehouse at certain level or there will be some unnecessary damage. LC1220T-TH front-end camera can do both for us, which means when the temperature and humidity go beyond the set number, the camera that collects both images and data will trigger the alarm and at the same time, through back-end linkage control system, start the air conditioner, light and spray system to restore the normal. Moreover, you can also manage the data through back-end in real time and have a regular output of data reports to avoid any possible energy waste resulted from inefficient use of air-conditioners.、

LC1200T-TH

Besides the aforementioned food and medicine, relics in museums and books in libraries also require a strictly controlled storage environment since they too are highly likely, sometimes irreparably, damaged by climatic factors. One recommendable solution is to keep the existing analog monitoring circuit and replace the equipment with HDCVI-IoT series of products that will ensure a 24/7 video surveillance and environmental monitoring. The system will collect and process the essential environmental data automatically as well as send out alarm signal and make air-conditioners respond accordingly if necessary, all recorded in regular data reports sent to you to review collectively.

In addition, the growth of plants and animals are commonly known as closely related to the temperature and humidity of the environment. They will stop growing or even die in a wrong environment. A LC1220T-TH camera plus a back-end recorder and light intensity sensor is nothing less than an indoor temperature and humidity monitoring system visualized. With various real time environmental data superimposed on the monitoring video, one can have a good control of crucial parameters of agricultural greenhouses, flower breeding rooms and farms, thus optimizing the efficiency.

LC1200SL-W
And as the demand for intelligent alarm system keeps increasing in the security industry, a variety of sensors have been poured into the market, among which, thanks to the continuous innovation of wireless sensor technology, are wireless sensors of smoke detector, water leakage detector, door contact, PIR, etc. They enjoy an increasing popularity among users since compared with traditional wired alarm system they have numerous advantages, including saving the money of wiring, easier installation and better fit to the general aesthetic of interior decoration.

LC1200SL-W

In this context another innovative product in the HDCVI-IoT series, LC1200SL-W, came into being. Based on the built-in low power consumption wireless gateway transceiver of 2MP HDCVI camera, a single camera provides access to 32 wireless alarm equipment within 100m. The gateway camera is compatible with 433MHz /868 MHz /915 MHz, all three major global wireless communication frequencies and conforms to Dahua Airfly protocol. Through wireless transmission, the detection device transmits the alarm signal to the camera which will capture the images accordingly and transmit through coaxial cable the alarm signal superimposed with video signal to the back-end devices. Which, in turn, put the real time surveillance images on the monitor screen and trigger alarm in real time. Meanwhile the alarm signal and the video signal are bound and stored, making it easy for users to search and review the corresponding video clips by the serial number of alarm equipment.

The whole system can be put together in a simple manner. It can be independently installed or uninstalled and operate on its own when not connected to internet. It is highly secure with no delay in transmitting video and trigger alarm, ensuring timely notification when an incident occurs. If connected to internet it allows remote control, rendering it possible for local forces to act at the same time with Alarm Center. The back-end intelligent video segmentation and tagging storage technology facilitates post event investigation. The ease of use and compactness of this system makes it suitable to use at home and small-medium sites monitored by alarm system.
