Ordinary people can also talk and communicate with each other through the camera on the network with video and voice. In addition, people can also use it for various popular digital images, video and audio processing.
Smart cameras are also called smart security cameras. Security is one of the main functions of smart cameras at present. When there is something happening at home, the camera will immediately push a message on the mobile phone to remind users. According to the statistics of the big data of Aurora, as of February 2019, the number of users of smart camera APP in the industry was 49.81 million, an increase of 44.9% over the same period last year. This shows that in the past year, people's demand for remote home and store watching has shown an upward trend, and smart cameras have also become a common household device.At present, the functions of smart cameras mainly include video monitoring, voice dialogue, security alarm and video review.
Video surveillance
Video surveillance is the core and basic function. The current intelligence is that the mainstream resolution of cameras is 1080P HD, which requires a high level of network. Most home cameras transmit data through WiFi, which is convenient to move. Some stores also install such cameras, which are mainly used to monitor the main points such as the cash register. This kind of camera that does not need to move can use the network cable, and the signal will be more stable.
Voice conversation
Most cameras on the market are equipped with the function of voice conversation. Users can directly have voice conversations with their families through the APP. Of course, although many devices on the market support this function, noise elimination, uneven echo and other situations still occur frequently and need to be improved continuously.
Security alarm
The security alarm function is mainly used to record vibration, special noise and other vibrations, and alarm through APP.
Video review
At present, smart cameras on the market all provide the function of video review, but most of them only provide the function of alarm review, that is, the video recorded after the alarm occurs can be reviewed, and the rest of the time can not be viewed, and it is a paid function. Few manufacturers can provide uninterrupted video retrieval function. The reason is simple: the cost of video storage server is too high. Video belongs to large flow files. If you want to achieve uninterrupted recording, storage and review, the cost will be many times or even dozens of times higher.
4G intelligent camera
The deployment of wired network is troublesome or the coverage of WIFI is limited. For example, security monitoring of mature commercial offices or new indoor and outdoor blank areas in residential areas, video monitoring is required for outdoor construction sites, and 4G intelligent cameras are required for the deployment of wired network is troublesome and scattered.
The 4G intelligent camera, also known as 4G camera and IPC, is mainly used for security video surveillance. Its feature is that the 4G communication module is built into the universal surveillance camera, allowing the camera to be directly connected to the network through the base stations of the three operators, breaking the limitations of the original deployment of network cables or WIFI connection, so as to achieve the purpose of remote monitoring.
