Mobile video surveillance is a dynamic mode in which mobile video images are captured at the front end; the back end is a professional-grade surveillance product that is tightly integrated with the traditional security industry, and can be received in a mobile manner such as: monitoring the remote real-time dynamic video through a mobile phone or a computer. It provides a simpler, more convenient, and more timely monitoring solution for businesses and families. The moving image acquires and encodes the image information through the acquisition device, performs the fidelity processing through the Hanhsx optimization algorithm, and performs the airborne transmission of the mobile signal through the CDMA/EDGE/3G multi-channel equipment, the Hanhsx ultrashort wave equipment, and the mobile satellite equipment, using the Wi MAX, 2.4 G, 5.8G and other urban network coverage technologies combine with CMMB for mobile phones, PDAs, MP3s, MP4s, digital cameras, and laptops. Make up the mobile launch, mobile receive mobile video surveillance network.
To achieve mobile video surveillance, you need to have the three most basic conditions:
First, there is a certain amount of network bandwidth. Currently, the actual downlink bandwidth of China Mobile's EDGE data network can be stabilized at 60kbps to 80kbps, and the actual measured downlink bandwidth of China Telecom's CDMA data network can be stabilized at 40k bps. It can be said that the current two data transmission speeds are very close to the optimal solution before 3G. We use the MODEM to access the Internet on the PC and get the image effects. We can get close-up image effects on mobile phones.
Second, mobile phone manufacturers provide development platforms. The development of the mobile phone industry is very rapid. For the sake of industrial development and encouraging the third party to intervene in the development of mobile phone application software, mobile phone manufacturers open the mobile phone development platform and provide an open development platform. This facilitates the development of mobile value-added services, which is also developed for non-mobile phone manufacturers. Mobile video surveillance provides a development platform. The ability of the mobile phone processor is strong enough to complete the video decoding and it is also easy to develop. With the development of semiconductor technology, the mobile phone processor has been rapidly improved in terms of low power consumption, such as ARM9 core provided by ARM, OMAP by TI, and X-scale by INTEL. All have video decoding capabilities.
Third, CMMB is the English English Mobile Multimedia Broadcasting (China Mobile Multimedia Broadcasting) technology is widely used.
Mobile video surveillance camera classification
1. WIFI Wireless Network Cameras WIFI wireless network cameras need to work with wireless routers, and wireless routers must be able to access the Internet.
Advantages: no wiring, installation and increase the number of cameras are more convenient, the cost of the Internet is relatively low. Disadvantages; installation must be done according to the instructions to do some simple network configuration before normal use; network camera to the wireless router's distance is generally required within the range of 30 to 100 meters, if you exceed this range you need to use a dedicated antenna or install a wireless router nearby; In places where wireless routers are used more densely, the operating frequency band of wireless routers must be set.
Second, wired network camera Cable network camera plugs directly in the network port or router that can surf the net to be able to work normally.
Advantages: It is very simple to use, can be used without any configuration, is not afraid of signal interference, is stable and reliable, and the cost of access to the Internet is relatively low. Disadvantages: Network cables are needed.
Third, 3G wireless network camera 3G network camera has mobile TD-SCDMA type, China Unicom WCDMA type and telecommunication CDMA2000 type, need to insert the corresponding mobile phone card in the camera.
Advantages: Easy to use, no need for any configuration to use; no wiring, no need for the user to set up any network, as long as the phone network and power supply can be used.
