Home monitoring solution

With the strong support of national policies, projects such as Safe City and Safe Community have been deeply promoted throughout the country, and the concept of national security has been basically formed. This has laid a solid mass foundation for the rapid expansion of the home security market. The demand in the home monitoring market is mainly for network monitoring, which can achieve remote monitoring. In addition to having a certain mass base, the emergence of 3G networks has also provided certain technical support for the development of the security home market.

1、 A Brief Discussion on the Functions of Home Surveillance

What functions should home security have, at what price range are devices equipped with these functions, and what should be noted when purchasing home security equipment?

（1） 720P has become a standard configuration for home monitoring

Looking at the entire civil security field, the resolution of home monitoring equipment generally reaches 1280 * 720, which is 720P image quality. This is not only to allow users to pay more attention to the details of their love for home, but also to enable users to communicate and share information with their families through this product. In order to cater to consumers' psychology, businesses equip their home products with high lens resolution, so the image quality of home monitoring equipment is one of their selection criteria.

（2） Strong practicality of motion detection function

After considering the picture quality, home monitoring devices need to consider what functions they need. For household users, there are usually elderly and children in most households, as the motion detection function is extremely practical. This function can not only meet the needs of families facing illegal intrusion, but also enable the device to intelligently identify moving objects and report to the "owner"; It can also provide alerts when children move or when elderly people fall, allowing users to stay informed about the situation at home and ensure timely understanding of their family's situation.

The motion detection function is still a good helper for lazy fathers and lazy mothers. Generally, when children are young, parents are always worried that their children may fall to the ground if they move around. However, this function can remind parents in a timely manner, so they don't have to stay by their children's side all the time. Even if you are asleep, it can detect your child's condition in a timely manner, allowing parents to easily have good sleep.

（3） Night vision function helps parents' take care of 'their children

For families where children have just slept in separate beds from their parents, parents are always worried about their children falling off or not resting well, but they are not always worried about the impact on their children's rest. Night vision function can help users eliminate their worries. You only need to open the mobile app to view your child's every move, and you no longer have to worry about disturbing their rest. The design of this feature is really thoughtful and can help parents solve many problems.

（4） Yuntai allows you to focus on a wider range of areas

At present, the appearance of civilian security equipment on the market is divided into two "factions", namely, relatively traditional appearance and very fashionable appearance. Home security equipment that retains the traditional appearance generally supports pan tilt zoom operation, in order to allow users to observe the situation of their loved home from multiple angles; And another type of enterprise testing sacrifices product functionality to support its fashionable appearance, using the beautiful appearance of the product to attract users and make it more like a home decoration.

No matter what aspects users consider, home monitoring products should be equipped with clarity, motion detection, night vision functions, etc. The appearance of the equipment also depends on whether users pay attention to appearance or functionality. In short, when purchasing home monitoring equipment, they should pay more attention to its performance and whether it can meet their own usage needs. They should not blindly pursue low price and high end, but should purchase according to their own usage requirements, so as to purchase the products they really need.

2、 Security analysis of home monitoring storage types

Next, let's talk about storage. In fact, the functions of current home monitoring devices are not much different, and they can generally meet the needs of home users. Therefore, the choice of functions is often not a big issue.

（1） Classification of Storage for Home Surveillance Cameras

As is well known, the earliest security industry did not distinguish civilian and industrial applications so clearly. If home users had monitoring needs, they only purchased some low-end devices for simple control, such as connecting them with analog monitoring devices through hard disk recorders. Nowadays, the application of home monitoring devices is very simple, realizing an integrated monitoring and storage platform, and the size is greatly reduced, making it convenient for users to place them in any corner of their home.

The current storage methods for home surveillance cameras are mainly divided into two types, namely local storage and network storage (cloud storage). In response to the needs of a large number of users, home monitoring devices have achieved remote monitoring. Through the deployment of APP software on mobile devices, users can view everything about their beloved home wherever there is a network, achieving no geographical or time restrictions.

For ordinary home users, these two storage methods may not have a significant impact on your application, but for those who require large storage capacity, cloud storage based home monitoring devices should be used.

（2） Portability of monitoring storage

When it comes to portability, whether the home monitoring device uses local storage or network storage, as long as there is a network, users can view their loved home. Through the alarm function of the home monitoring device, once a stranger enters, users can also receive timely warning information and watch everything happening in their home by turning on the camera. From this perspective, the portability of both may not be apparent.

But portability is not only reflected in one aspect, but also a comprehensive consideration of the performance of monitoring equipment. At present, the TF card supported by home monitoring devices is only 32GB, which may not be able to meet users' long-term recording needs for real-time home recording. However, network storage does not have size requirements for space, and massive storage space can be freely stored. Users can select or demand video recordings from anywhere, making it more convenient to apply.

And the author has previously tested home monitoring devices, recording for 11 minutes and generating approximately 71MB of video files. Each minute produces approximately 6.5MB of video, which takes up about 9GB of space. It can be seen that localized storage is not suitable for long-term video recording.

Some locally stored monitoring devices, in order to reduce the space occupied by video data, adopt the method of image storage, that is, whether the user actively captures the image or the device itself alarms and takes screenshots, they are all presented in the form of images. Although it can save a lot of space, it also loses the ability to capture animation image information and misses too much important information.

（3） Security of Home Monitoring Storage

For home users, home monitoring information involves too much personal privacy, so information security becomes very important. What are the impacts of local storage and network storage on security, and which method is more secure?

Most people may think that storing video information in cloud storage is not secure enough, as it is not as practical as having a nearby storage card. However, have you considered that once a hacker invades your monitoring device, the video information stored locally will be fully exposed to the hacker, and of course, privacy issues cannot be discussed.

Previously, CCTV had already exposed vulnerabilities in surveillance equipment, allowing criminals to easily enter the home monitoring network. Not only individual users, but also some * and shops have been targeted. Hackers can not only view your information, but also manipulate the surveillance footage. The footage that users see may not be the real footage at home, but rather a "false impression" created by hackers for users.

Cloud storage, on the other hand, stores video information on a dedicated server. Both users and others require certain permissions to access it, and the stored data is encrypted. Even if it is invaded by criminals, they still cannot see your video information, which is of great help in protecting user privacy and security.

For these two storage methods of home monitoring devices, it cannot be simply said which one is better or worse. However, from the development trend of home monitoring storage, more monitoring devices will apply cloud storage in the future, and technologies such as big data, cloud storage, and intelligent analysis will definitely be the major trend of future monitoring device development.
