We supply various types of voltage protector including TV Guard, Fridge Guard, Digital Voltage Protector etc.
The voltage protector is good for an automatic protection of the home appliances in case of under-voltage, ultra-voltage and electricity stoppage. For instance, it may be always harmful to the normal operation, cut their service life, or even burn down the compressor motors for air-conditioners, refrigerators and freezing cabinets if the supply voltage is too low or too high. Especially, instant power stoppage and restarting supply with the electricity net creates a strong voltage impact which is very hazardous and may damage the compressors. This protector applies a digifax technique, which can immediately disconnect the load supply and provide the compressor with a time-retardant power reconnection with a perfect result of protection for the compressor.

With the development of networking and the intervention of telecom operators, the development of 3G wireless surveillance technology has brought great development space to the security market. Industry experts pointed out that the civilian market will become the area of ​​greatest potential for video surveillance.
For individuals, security products have a wide range of applications, including security, collaboration, and entertainment. Therefore, the business of security products mainly focuses on uploading videos and browsing video information in real time. To achieve the goal of uploading video anytime, anywhere, the front end of the system will no longer be confined to traditional IP cameras. In the office, users can upload video and PC screens in real time through PC+USB cameras to achieve collaborative applications. In the outdoors, users can use the camera. The real-time uploading of video data by smart phones is used for video site or microblogging entertainment sharing. In the emergency scene, real-time uploading of live video data through handheld terminals or smart phones provides intuitive and reliable basis for emergency command. To browse the video anytime, anywhere, the client is no longer limited to the previous PC, you can choose smart phones, handheld terminals, and even 3G Internet access iPod.
Under such circumstances, civil defense must first solve technical problems and ensure that monitoring points and browsing points are not restricted by time and place. First, the location of monitoring points can be either mobile or fixed, and the encoding device can be IP. Cameras, PCs, smart phones, and other multimedia terminals, transmission can be based on wired, 3G, WiFi and other types of network; Second, the browsing point to be unlimited. Whether at home, office, on business trip or on the road, users can access alarm information anytime, anywhere through PC, smart phone or other multimedia terminal devices, browse real-time video or playback video, and learn what they need.
In addition, civil defense needs to solve operational problems. Telecom operators have a strong basic network, user base, and mature operating experience. They are relatively suitable operators. Security operation companies have rapid operations and flexible business models. They are the best candidate carriers; there are also some emerging network operators. Business, can provide users with a variety of entertainment, home video and other information, which is the basis for its involvement in the civil defense market. However, because these emerging operators have not been developing for a long time, it is still necessary to pass the test of time when they can be competent for the work of operators.
It is not an easy task for security to enter the civilian market and it is not easy to solve the problems at all levels of technology, operations, and users. It is a gradual process.
The security needs of the shops and homes and the security business model are similar. They are all monitored when there is no one, and are monitored when there is no one. The purpose is fire prevention and theft prevention. The family may also involve remote care. The focus of monitoring in these areas is to allow users to obtain detailed information on events in a timely manner and help users access the system at any time. At present, the business model of shops and home monitoring is IP cameras + various types of alarm detection equipment + platform access. In this mode, when the user leaves, the alarm is triggered. When an unexpected situation occurs, an alarm is triggered. The alarm information is sent to the user in the form of a short message. At the same time, the alarm is activated and the IP camera is enabled to perform preset rotation, capture of pictures, and start of recording. After receiving the message, the user logs in through a PC or mobile phone and browses the live video in real time. After the confirmation, the user takes the measure and the user disarms after returning.
