Doorscope, also known as cat's eye, is a convex lens installed on the door to peep out the door from the inside. Few people will associate it with intelligent products. When our life enters the era of interconnection of everything, everything will become "smart", not only with stronger and more diversified functions, but also with remote control capabilities, Realize intelligent and remote home. As an important part of smart home, electronic cat's eye incorporates disruptive and innovative information technology revolution into tradition, realizes infrared automatic detection, early warning and capture, and transmits images and videos of suspicious persons; When there is no one at home, you can have long-distance two-way conversation with visitors.

With the concept of "technology facilitates your life", Cloud Vision brand is committed to creating a new form of intelligent life with happiness, love, fashion and technology. Cloud Vision K1 is the first generation smart cat's eye product created by the Cloud Vision team, and also the first product in the field of smart home. There is a big difference between the Cloud Vision K1 smart cat's eye and the traditional cat's eye. It can realize the interconnection of mobile phones, cat's eyes and users through the network, so that you can really see everything at any time and anywhere.

The outer package of Yunshitong K1 is exquisite, large, square, and solid. It is wrapped in transparent plastic paper, but has no tamper proof label. The upper cover is printed with Yunshitong's logo. The lower cover is a brief introduction to the functions of the cat's eye. There is a groove between the upper and lower covers. I like this design, which is easy to open and adds a sense of hierarchy.

Compared with the shell, the material of the inner bracket is a little unsatisfactory. The material is soft, and the cat's eye camera installed inside is easy to sink. But what is worth praising is that each accessory has its own small box, and the name or function of the accessory is printed on the outside of the package, which makes it clear at a glance.

There are not many accessories, but there should be some accessories, including charger, 3m long charging cable, removable battery, cat eye camera and fixing screws.

Yunshitong K1 is equipped with a 3000mAh large capacity battery, which can not only avoid the impact on the beauty of the home due to long-term plugging of the power cord, but also ensure that it can continue to operate in the event of power failure. The parameter marked by the charging head is 5V 1A. Theoretically, the charging of 3000mAh battery will be slow, but in the actual test, it takes about 1.5 hours to charge from 10% to 100%, which is quite fast. The charging line and the charging head are separated. When the charging head is broken, it can be replaced at any time.

The top of the host is the power switch and the battery compartment. Press and hold the key for about two seconds to switch on and off the machine. After the battery enters the battery compartment, the position cannot be locked automatically, but the battery compartment door needs to be closed before it can be fixed. The design of the battery compartment door is a bit thin, and the joint position is not fine enough. It is recommended not to open and close the battery compartment door frequently. Below the fuselage are the bell mouth, the Reset key and the Micro USB port. The layout is reasonable.

　　
The bottom of the host is connected to the cat's eye through a push type interface. There is a direction indicating arrow beside it. Press the connector of the cat's eye gently according to the indicating arrow. Of course, before connecting the cat's eye, pass through a metal fixing plate, which is used to fix the cat's eye and the host. The cat's eye and the fixed plate are connected with the fixed plate through the screw guide on the cat's eye, so there is no need to drill holes on the door, and the installation is very convenient. When the host starts up for the first time, it will automatically play an installation video, which is very clear and easy to understand. Of course, it can be replayed, which is worthy of praise.

Yunshitong K1 uses a 5.0 inch display screen with a resolution of 480X800. This resolution is inferior to the current mobile phone screen with a minimum 720P display. The display effect is really ordinary, but it is still no problem to clearly display the faces of visitors outside the door. After the host is powered on, tap the screen or click the Home key to bring up the menu. Various operations, including all parameter settings, can be completed through the touch screen.

Cat's eye has infrared detection function. When a visitor stays outside the door for more than 30 seconds (the time can be set by the user), Cat's eye will give a voice prompt: "Friend, you have stayed outside my door for more than 30 seconds, what can I do for you?" At the same time, it will take pictures of the visitor and send them to the mobile phone. If it is a thief, it will scare him away. If it is a water delivery or express delivery, it is not there, and you can also have a remote conversation through the mobile phone APP. Below the cat's eye is a doorbell button. When pressed, the screen lights up automatically, and the situation outside the door is clear at a glance. At the same time, it will send a video connection request to the mobile phone APP.

As an intelligent device, the corresponding APP is indispensable. The "Cloud Vision Life" app can be downloaded by scanning the Erwei code on the packaging box or the host or through the app store of the mobile phone. The main color of the APP interface is light blue, creating a harmonious atmosphere, which also conforms to the theme of the family. When using APP for the first time, the system will require registration, which can be completed in a few simple steps through email or mobile phone number.

After logging in, the system will prompt to scan the binary code on the host to bind the cat's eye. After binding, the device can be operated and controlled. The host is connected through wifi, so before binding, the host must be connected through wifi. The wifi connection of the host can be completed through the operation of the host itself, and the method is also very simple. There are few ways to connect wifi with mobile phones.

The main interface is relatively fresh. The bound cat's eye will be displayed in the middle of the main interface. After clicking, you can perform related operations on the cat's eye. One login account can add multiple cat's eyes at the same time, and you can share the device with your family to connect, that is, one cat's eye can be bound by multiple accounts.

Real time intercom can be conducted between the host and mobile phone through the APP, and Cat's Eye supports the transmission of real-time video to the APP, but the speed depends on the connected wifi speed. I used 4M telecom broadband to test, and the video quality is smooth, and the speed is smooth in idle hours, but it will be very stuck in busy hours, but it may also be because the server is not strong enough, Because I tested the 360 camera at the same time, the video transmission is relatively smooth. The lens adopts ultra wide angle lens, which has a wide visual range, but has the disadvantage of distortion. The cat's eye lens will automatically turn on the infrared ray when the light is insufficient. It can still shoot images with high brightness in dark environments, but at this time, the definition will decline, and there will be serious color deviation.

Cat's eye supports the infrared detection function. When a suspicious person stays at the door for 30 seconds, in addition to the voice prompt from the cat's eye itself, it will automatically capture photos and send them to the mobile phone APP in real time. If the APP terminal device is self starting, the mobile phone will also give real-time prompts. In addition, you can also click the horn button on the main interface to make the cat's eye give an alarm sound to scare off the bad guys. However, once the button is pressed, it must wait for the alarm to complete before automatically stopping (about ten seconds). There is no button to eliminate the alarm. If you accidentally press the wrong button, it will easily cause embarrassment.

The pixel of the photo is not high, only 1 million pixels. Although the portrait can be clearly identified, this pixel is obviously not enough when you need to zoom in to view details. In addition, there is no button to save the image in the APP, and the image can only be saved by screenshots. This is a lack of functionality, and I hope that future versions can be improved.

Except that some parameters must be set on the host, most functions and parameters can be set online in the APP. For example, time zone, infrared sensor switch, movement detection switch, restart and close cat's eye, etc., but not all functions can be set in APP. For example, the time of staying outside the door, weather broadcast switch, home location, volume, door ringing type, etc., can only be set on the main body. If all these functions can be set on APP, it will be more convenient.

Through experience, the smart cat's eye has indeed overturned our understanding of the traditional cat's eye, providing a strong guarantee for our travel convenience and home safety. The overall function of the Cloud Vision K1 is still good, simple and convenient to install, friendly and easy to understand the operation interface, but there is still room for improvement in the details of workmanship and hardware configuration.
