Security monitoring how to achieve security in smart home systems

Various home terminal devices and cameras play an increasingly important role in life. We can get event notifications on mobile devices or via web browsers through professional software to get free cloud storage services for recording videos. With the popularity of the network, more and more home networks access the Internet through ADSL or FTTX+LAN, wireless coverage of indoors using high-performance wireless indoor APs or wireless routers, enabling indoor wireless network cameras to be wirelessly installed. The network is connected to a home wired network. Users can watch video remotely using Wi-Fi wireless technology and home cameras through a browser or other mobile device.

It is understood that the current low-cost home camera can provide professional-level monitoring performance of up to 2 million pixels, 30fps. They offer a much smoother video and image quality than entry-level DIY cameras that typically have only 1 million images and 15fps. Some home cameras even feature mechanical infrared cut-off filters (ICR) that provide sharper images at night and more realistic colors during the day.

Specifically, the home surveillance camera also has the following functions:

1. Remote real-time monitoring

Users can use the monitoring client software to watch remote monitoring videos in real time via the Internet. The monitoring client software can be installed on computers and smartphones.

2. Remote alarm and remote withdrawal prevention

The wireless camera of the home video surveillance system can obtain images within a range of 15 meters, and its video analysis function can send alarm information to the user's mobile phone and client software in the first time. The user can use the computer or mobile client software to remotely and conveniently manage and disarm the monitoring site.

3. Network storage image

The home wireless video surveillance system is capable of saving surveillance video over the network. In the state of no alarm or disarming, the video of the monitoring place can be saved on the network hard disk at a set time interval; in the case of an alarm, the image can be continuously saved on the network hard disk. Until the alarm is released. The user can watch the surveillance video playback through the client software at any time.

4. With night vision, pan/tilt control and other functions

Choose a wireless camera with infrared night vision to shoot normally in a light-free environment. If you use a 360-degree rotating pan/tilt, you can also greatly expand the monitoring range to avoid monitoring dead angles, so that one camera can achieve the effect of multiple cameras.

5. Mobile interactive monitoring function

Mobile phones are the most mobile monitoring tools. Powerful monitoring client software can be installed on smartphones, while ordinary non-smart phones can use the browser on the phone to conveniently view real-time and historical surveillance images. When an alarm occurs, the phone will receive a text message with a link to the monitored image, and the user can open the monitoring image directly in the text message. Users who are not accustomed to using a mobile browser can also send a text message to the service number. The system automatically replies to the short message of the current image link. The user can open the monitoring image in the short message, and can also use the mobile phone short message to perform the operation of removing the defense.

Potential home monitoring market analysis

In addition to the home market, we can see other growing network monitoring needs, such as child and elderly care monitoring services, video access in kindergartens, baby care centers and elderly care centers, where parents can watch old people, children's activity records and live video. In addition, more detailed and real-time communication between parents and teachers can also be carried out. In fact, in addition to security monitoring, modern home network cameras are increasingly inclined to join the intelligent analysis function. For example, for the monitoring of children such as kindergartens and nurseries, motion recognition and analysis can help prevent accidents in young children or take timely action in the event of an accident. For the elderly or medical care, the network camera can play a wider range of functions. When the safety monitoring system is combined with alarms and other sensing systems in the home, the synergy will be much greater than that of a single camera. After detecting an abnormal invasion, the camera can immediately judge and analyze whether it is an intruder, send a signal to the alarm system at home, notify the security company or the police unit to minimize the loss.

According to relevant data, the current smart home market is huge. There are more than 100 million potential smart home customers in China. By 2015, the output value of smart homes will reach 1,240 billion yuan, and it is expected to reach 2 trillion yuan in 2020. Compared with other smart devices (such as smart watches and smart bracelets for health), smart security or newer and more fashionable smart hardware products are more demanding for users. However, the lack of security performance of smart home security makes consumers discouraged, and too high prices make consumers hesitate. This way, even if you have a huge number of potential customers, you can't achieve the popularity effect.

Home camera monitoring faces security issues

When home network cameras move from analog to digital and from full IP to mass market, combining cloud services and big data is an inevitable trend. Security challenges are also a problem in digital home security monitoring systems. In order to link with other smart home products, the heterogeneous network convergence platform is an inevitable development trend. However, the more devices are connected, the greater the risk. A router/home gateway that is considered a smart home hub can implement many services, but the Wi-Fi network has been cracked. Therefore, how to protect the user's use security, so that the surveillance video in the home is hacked and the outflow becomes an important issue. Home network cameras must stand out in a highly competitive market, and different technologies and products must be considered to give users a satisfactory experience.
