Why do we need a visual doorbell?

Purchase reason:

New home floor is relatively low, for security considerations, decided to configure security equipment to make up for the short board of home safety. As a loyal user of Dama station, I referred to many security product experience articles in the station, and finally selected 360 visual doorbell d819 under the recommendation of many big men.

360 visual doorbell: packaging and accessories

▼ We thought that the packaging of this 360 video doorbell would be relatively simple. After all, the price was very beautiful. But after the arrival of the goods, the exquisite outer packing really brightened people's eyes and didn't feel embarrassed when it was used as a gift：

After opening the package, the black and white doorbell host and signal base station are very eye-catching.

▼ The 360 visual doorbell body has a simple and mellow overall shape. There is no redundant design on the appearance, and the functional area planning is obvious：

▼ The top is the indicator light, photosensitive probe, camera and microphone; the middle is the infrared night vision lamp, which supports the night vision function;

▼ The bottom is the doorbell button. When the visitor approaches the doorbell, the light will be on automatically, and the doorbell information will be sent in real time by pressing the button.

▼ A 360 view of the back of the doorbell:

The doorbell is designed as a detachable structure, which is not completely locked. It has a built-in 5000mAh rechargeable battery and uses standard USB port for charging. It can support 6 months of battery life under frequent use to avoid frequent charging. The charging port and switch button can be seen in the figure below.

▼ In addition to the USB charging cable supplied with the package, 360 also comes with expansion screw accessories. The key point here is that there are two installation methods for the 360 visual doorbell light, one is 3M glue fixation, the other is screw fixation. PS: I tried it. 3M glue with industrial strength on the back is really hard to shake on the wall

Signal base station and installation

▼ Indoor signal base station with 360 video doorbell: Although the volume of the signal base station is small, it is the guarantee that the doorbell can work normally.

Firstly, the loudspeakers of the signal base station can ring like the traditional doorbell to remind guests to visit; secondly, the base station is the transfer station connecting the doorbell and the mobile phone app to ensure the audio and video transmission between the mobile app and the doorbell host, so as to realize the function of visual doorbell;

Finally, there is a TF card slot on the side of the signal base station. In addition to 48 hours of video cloud backup, TF card can also be installed for local storage to achieve double insurance.

▼ The signal base station supports wide range voltage of 100 ~ 240V, and the label on the base station positions the 360 intelligent visual doorbell as "video playback equipment with storage medium"

It is suggested that the doorbell should be installed at a height of 1.4m. If there are children at home, it can be further adjusted according to the specific situation.

▼ The installation effect of 360 visual doorbell is relatively small, fixed on the door does not feel abrupt.

In addition, 360 visual doorbell can be fixed at the position of door frame or wall. If it is installed on the metal door, the signal reception will be affected. However, before pasting, the door can be closed to test the signal strength and then determine the specific position of pasting. Friendly reminder: be sure to select the installation position before pasting.

▼ The ring blue light will produce the effect of breathing lamp when someone is close to the door, indicating the position of the key. When the doorbell is pressed, it will turn around and the base station will remember the bell.

App installation and debugging

Installation and commissioning:

Use 360 visual doorbell with "360 smart camera" app. Enter the app home page and click the + sign in the upper right corner to add the device:

▼The 360 security ecosystem is still very rich. "360 smart camera" not only supports the visual doorbell, but also supports other 360 security products, such as small water drop camera. Select 360 visual doorbell in the upper left corner to start setting:

▼ The 360 visual doorbell needs to be used with the signal base station. Follow the app's setting guidelines, connect the signal base station to the home 2.4G Wi Fi signal, and then complete the pairing between the doorbell host and the indoor signal base station. The setting of app is simple and easy to understand, even if it is Xiaobai

360 video doorbell functions

360 visual doorbell provides rich setting options. Detailed function options are in further settings. It is recommended to read the complete setting options for the first time.

Ultra wide field of view and clarity:

360 visual doorbell provides a 162 ° angle of view, and the left and right half is 81 ° and 90 ° with only 9 ° difference, and the distance between 180 ° is not big. If you want to further increase the viewing angle, you need to configure a large angle convex lens similar to a fisheye lens. As a result, the manufacturing cost will rise, and the distortion of lens will also make the picture distorted. According to the actual test, the 162 ° wide angle of the doorbell achieves a balance between the picture and the image quality, and the 1:1 picture ratio can also obtain more pictures in the vertical direction. I tried to keep my body close to the wall, but I still didn't escape the eye of the doorbell. It can be seen that under the 162 ° visual angle, it is still very difficult to hide myself.

▼Meanwhile, 2 million 100 thousand of the super clear pixels are also very awesome. From the real-time pictures of the 360 smart cameras APP terminal, we can see that the picture effect is quite clear. Moreover, I have also paid special attention to the delay of the next picture. The delay is still relatively low, within one second.：

Infrared night vision function：

In addition to ultra wide HD field of Vision coverage, 360 visual doorbell also claims to have Ultra HD night vision function, and the dark corridor can be seen clearly. Because the corridor lights in my community are managed by the property, they are on all night. In order to experience the infrared night vision function, I had to take the doorbell to my friend's house to rub the corridor, which was also a fight.

▼ The following figure is the imaging effect in the elevator hall, which is satisfactory to me. You can see the patterns of the tiles, you can see the elevator is now on the first floor, and even the downlights on the ceiling in the distance. I was also surprised that the wide-angle vision was not lost while night vision was being recorded：

Movement detection：

The 360 video doorbell also has the function of detecting the abnormal movement in front of the door. After turning on the human movement detection in the 360 smart camera App settings, as long as someone stays at the door for more than 15 seconds within 3 meters of the door, our mobile phone will receive a reminder to check the situation at home in time. This function is very easy to use. Usually, we can't stare at the real-time screen at the door 24 hours a day. Therefore, when someone is staying at the door, we can know the situation of the door from the push message, and we can also use voice reply to give warning.

▼ In app, you can see the pictures of someone staying at the door in recent years. The first section is the neighbor opening the door, and the second section is the courier passing by. If you live in a community with 2 elevators and 3 households, you won't get the picture of neighbors entering the door, which will dispel the concerns of the neighbors.

Demolition alarm：

▼Because the doorbell is installed in an outdoor conspicuous position, the doorbell not only protects the safety of the home, but also is very important for its own safety. Therefore, the 360 visual doorbell has the function of forced demolition alarm. After the function is turned on, if someone tries to remove the doorbell host from the mounting seat, the doorbell will automatically record the video information, push the alarm information to the mobile phone, and at the same time send out the alarm sound through the loudspeaker to deter criminals.

After testing, the oversized alarm sound shocked all the neighbors upstairs. In the app record, you can also see the warning of forced demolition: "someone is forcibly dismantling the doorbell.".

Face recognition function：

In order to identify the identity easily, 360 visual doorbell has added the character recognition function, we can carry on the identity remark to the person who appears recently. In the "home page" - "character recognition", you can see the picture information of the person near you, the doorbell will automatically take photos and make a backup, and then classify this part of information to identify the frequency of the characters.

People can be noted to family tags. There are also options such as "suspicious person", "dangerous person" and "express" in the optional items. When visitors press the doorbell, the indoor base station will broadcast the identity information, which is convenient for us to obtain the identity of visitors outside the door when we use the mobile phone screen (this function is especially suitable for the elderly who are not good at using smart phones).

Endurance

360 video doorbell uses a large capacity lithium battery with 5000mAh built-in, which can be recharged and used repeatedly. It can be used continuously for 6 hours after full charge About months ago, from the perspective of the products on the market, I feel that the battery life is very good, and the recyclable charging is really convenient. Finally, I can say goodbye to the environmentally friendly dry batteries. In addition, there is a real-time power display in the app, which will remind users to charge when the power is low.

▼It's been a long time since I bought it without charging. At present, it shows that the battery is still 59%.

360 visual doorbell: experience

The crime rate is often lower in the monitored areas, and the price of the video doorbell is not expensive. On the one hand, you can buy a safe one, on the other hand, you can avoid a lot of unnecessary trouble. The existence of the visual doorbell can serve as a warning to potential dangerous elements. Compared with the traditional cat's eye, 360 visual doorbell has larger angle, less blind line of sight, and more reliable identification. It can be called in real time on app, and communication is convenient and fast.

Suitable crowd:

1. There are children and children in the family.

2. People living alone, especially women.

3. The residents who rent more houses and have complex living environment.

4. Middle aged and elderly users. (the combination of character recognition and doorbell broadcast is very suitable)

In addition, spending more than 300 yuan to buy a visible doorbell is like setting up an invisible warning line. I think it's worth it. Compared with all kinds of news about "cases cracked within hours", I think the lowest cost is prevention.
