360 Smart Camera
Friends who have a little knowledge of smart cameras should know that most smart cameras on the market use white+black mixed color matching. The main body part is mainly white, and the camera part is presented in black to form color contrast. Not only smart cameras, but also for other smart home products, this kind of black and white mixed color is more versatile and can be integrated into a variety of scenes without conflict.
video recording
Although Lenovo's Lecoo Premier Watching R1, Mijia Xiaobai and 360 Smart Camera all support 1080P video recording, the difference is that Mijia Xiaobai and 360 Smart Camera both use H.264 video encoding. At present, most cameras in the domestic market also use this video encoding format, while Lenovo's Lecoo Premier Watching R1 uses H.265 encoding format.
H. The compression rate of H.265 video coding is very high. Compared with H.264, H.265 occupies less space. However, high compression ratio does not mean poor picture quality. On the contrary, the picture quality of H.265 is better than that of H.264. H. The huge block data in H.265 is completely independent, and noise is easily generated at the boundary of the huge block in the encoding process, affecting the overall picture after synthesis. H.265 supports Deblocking+filter, which can monitor the huge block boundary data, smooth the huge block boundary, reduce video noise, and improve video quality.
Therefore, Lenovo Lecoo Kanjiabao R1, which uses H.265 encoding, has an inherent advantage in video recording. Its recorded video has not only small capacity, but also higher video quality.
For home surveillance intelligent cameras, the larger the FOV, the larger the range and more content can be monitored. The field angle of Mijia Xiaobai camera is only 100.2 °, the 360 smart camera is 118 °, and Lenovo's Lecoo looking at the family heirloom R1 is 130 °. Lenovo's Lecoo looking at the family heirloom R1 is one of the devices with the largest field angle. Its vision is wider and the monitoring range is wider at the same location.
Security
In recent years, security problems of smart cameras frequently occur. After the smart camera in the home is cracked, the user's daily life is peeped. Such incidents are common. The security problem of smart cameras is widely concerned by society.

Physical privacy masking
For the security problem of smart cameras, different manufacturers have launched corresponding solutions, among which physical privacy masking is a security problem that can effectively prevent smart cameras from "peeping".
In order to prevent the smart camera from spying on the user's personal privacy after being cracked, 360 Smart Camera and Lenovo Lecoo Kanjiabao R1 can both rotate the camera downward to cover the camera. As long as the user physically covers the camera when not in use, it can effectively prevent "peeping". It is worth mentioning that although Mijiaxiaobai's camera also supports rotation, it does not support physical privacy masking, and its camera cannot conduct physical privacy masking on its own.
switch button
Among the three smart cameras, Only Lenovo Lecoo Jianjiabao R1 is equipped with physical switch button and reset button (on the back of the machine body) 360 smart camera is not equipped with a switch button, but only a reset button (on the back of the machine body). Although Mijia Xiaobai is equipped with a button on the front of the machine body, this button has no switch function, but is used to wake up Mijia Xiaobai's voice assistant function.
As we mentioned above, in addition to the physical privacy masking, the physical switch button is also a security guarantee for the smart camera. Users can directly turn off the smart camera through the physical button when not in use. Only Lenovo Watching Premier R1 has achieved this

If the "physical privacy masking" and "switch button" mentioned above belong to "physical defense", the next thing to say is "magic defense". As we all know, if the smart camera does not use cloud storage, its surveillance video must be saved in the Micro SD card of the body. If the Micro SD card is stolen, the surveillance video will be stolen.
The videos recorded by Mijia Xiaobai and 360 smart cameras are ordinary MP4 companies. As long as the Micro SD card is stolen, the monitoring video content will be seen by others. Lenovo's Lecoo Premier Watching R1 uses a unique v265 format to save the file, which cannot be played in the player on the computer. If you want to watch the surveillance video of Lenovo's Lecoo Premier Watching R1, you can view it intelligently through the account bound app, which greatly increases the security.
At present, in the domestic smart camera market, the vast majority of products use ordinary MP4 for storage, Although it is convenient for users to watch videos on the computer, its security is low. Lenovo Lecoo Watching Premier R1 is one of the few smart camera products on the market that uses v265 encryption format to store surveillance video, and its security is stronger than similar products.
App and ancillary functions
Mijia Xiaobai uses Mijia App
In terms of app functionality, Mijia Xiaobai uses Mijia App, which has relatively simple functionality, such as normal monitoring recording (supporting 360 ° rotation control), video calling, intelligent recording (only storing videos of dynamic objects), etc. In addition, users can wake up Xiaobai's voice assistant through the buttons on the front of Mijia Xiaobai's body. The function of the voice assistant is relatively simple, which is to query the weather, temperature, time and date, as well as answer some daily encyclopedias, tell stories, tell jokes, etc.
It is worth mentioning that when new users register, Mijia Xiaobai does not have a free trial cloud storage service, which requires users to pay extra.

360 Camera App
360 Smart Camera basically has the same functions as Mijiaxiaobai, but it has more control over surveillance video than Mijiaxiaobai, and supports cutting, fast forwarding and other functions. It is worth mentioning that 360's smart camera will have its own official advertisement exposed on the home page. At the same time, 360 does not provide new users with free trial cloud storage services, which also require users to purchase additional cloud storage services.
Lenovo sees the Jiabao App
In addition to the conventional monitoring video control, Lenovo Premier Watching also supports simultaneous playback of four monitors. If users purchase four Lenovo Premier Watching R1s and bind them to the same account, then users can view the monitoring pictures of four Premier Watching R1s simultaneously through one App client. Lenovo Lecoo Premier Watching R1 is the only one of the three smart cameras that has 30 days of free cloud storage service for users After a new user registers, he or she does not have a Micro SD card. He or she can also temporarily save the video through a free 30 day cloud storage service.
Lenovo's Lecoo Premier Watching R1 also supports AI voice recognition technology. When a voice appears in the environment, Lenovo's Lecoo Premier Watching R1 will directly push real-time monitoring images to the mobile app, so that users can timely understand family dynamics. If a movable object is found, Lenovo's camera for watching Premier R1 will automatically follow and capture dynamic images, and push alerts and related videos to the App in real time.
summary
For an intelligent camera, video image and security are the most important, followed by control and other ancillary functions.
Mijia Xiaobai's security is the worst among the three. There is no physical mask, entity switch, and encryption format. At the same time, its field of view angle is the smallest, and the content of the observable image is the smallest among the three.
The 360 smart camera performs well, but it is hard to accept that it embeds advertisements in the App
Lenovo Lecoo Watching Premier R1 has formed a triple security protection through physical masking, physical switch and encrypted video format. Its security is undoubtedly the best of the three. At the same time, the encoding format of H.265 and its wide field of view also enable it to have a better video picture than the other two. It also supports the function of 4 monitors playing at the same time.
