Close to high-definition smart phone monitoring to a new height

The mobile video surveillance application is a product of wireless communication network and video surveillance development to a certain stage. Currently, the average downlink speed of the three major operators has reached more than 1Mbps, and the mainstream smart phone CPU also exceeds 400Mhz, which can achieve clearer and smoother monitoring results.

Two kinds of mobile phone monitoring modes. P2P mode refers to direct access to monitoring devices such as DVRs and IP Cameras through mobile phones. Advantages There is no need to deploy streaming media servers. All audio and video data only occurs between the device and the mobile phone, providing better privacy protection for users. The disadvantage is that the network setting of the surveillance camera equipment is relatively complicated. In general, the IP address needed for the mobile phone access must be obtained through port mapping and the like. For the average user, the threshold is higher. Most of the equipment manufacturers that are currently positioned as foreign trade models use the P2P model to provide mobile video surveillance.

2. The CS mode refers to the way in which the monitoring camera device transmits video to the streaming media server and the mobile phone obtains audio and video resources from the streaming media server. To deploy a streaming media server or to rent a streaming media server provided by an operator, you must pay a monthly fee for the functional service fee. The advantage lies in that the front-end encoding device is simple to set up, and almost all types of access networks can be quickly accessed to implement mobile video surveillance functions. The CS model is more suitable for large and medium-sized projects. Companies that are interested in the domestic market and are good at integration projects mostly adopt the CS model.

In the future, close to high-definition smart current mobile phone monitoring has become a standard feature of various monitoring devices. However, according to statistics from professional survey companies such as third-party data, such as the APPStore monitoring software download data, the opening rate of the current mobile video surveillance function is only about 30%, and the proportion of foreign countries is slightly higher than 50%. The reasons for the popularity of this feature: compatibility, different brands of operating systems are not compatible; charges, high-volume mobile phone monitoring services have generated high costs; power consumption, most mobile phone monitoring using the phone's CPU decoding operations, power consumption Large; effect, mobile video surveillance using wireless network bandwidth, many areas do not cover 3G, insufficient bandwidth results in poor playback.

However, the factors that restrict the development of mobile video surveillance applications are changing with the development of science and technology and the transformation of the whole business operation. The development direction of future video surveillance is high-definition and intelligent. The development trend of mobile video surveillance will keep up with the trend. Higher bandwidth, higher resolution, and stronger decoding capability will surely bring HD video playback to a new level. height. At the same time, intelligent monitoring algorithms will also be ported to mobile phones in the future. The integration of PCs and mobile phones can be seen on the iPad. In the future, any function that can be realized on PCs will appear on mobile terminals. The era of monitoring at anytime and anywhere is quiet. advent.
