A netizen told about his startling moment in the morning：

At about 6:00 a.m., she was awakened by the rustle of the lock at the door. She lived alone and no one should visit at this time. She immediately realized that someone was crowing the door. She wanted to confirm the situation outside the door through the cat's eye, but the people outside had obviously thought of it and blocked the cat's eye.

So she banged on the door, hoping to scare away the people at the door. But the people outside the door were not scared away, but answered: open the door! The girl immediately chose to call the police, and opened the public release, telling the door: I have called the police! The door is quiet, the girl is very smart, she did not open the door to confirm, but chose to wait for the police to come.

Fortunately, after the police arrived, the people at the door had left. Unfortunately, the police did not find any traces of crime, so they did not file a case, and the community also refused the party's request for investigation and monitoring.

Old people who live alone have always been the targets of thieves. They leave marks at the door and wait for them to enter the room quietly after they go out or in the dead of night......

In fact, these potential risk factors can be avoided. Just install a smart doorbell D1 at the door of your home. All the potential dangers can be solved easily!

Installation reason 1: large visual range, dim and clear light

Xiaozhi's home uses the intelligent doorbell, and the most intuitive feeling is: whenever there is movement outside the door, no matter whether the corridor light is on or not, you can see it very clearly.

You can take a look at the image comparison of the intelligent doorbell with the eye when the light is sufficient and dim. In addition to turning black and white, the image effect of the intelligent doorbell under night vision mode is similar to that when the light is sufficient. The details of the picture are still kept intact~~~

In addition, Xiaozhi also compared the image effect of a certain brand of intelligent doorbell. It can be seen that under the same environment, the image effect of the intelligent doorbell will be better, clearer and less distortion.

Installation reason 2: 24 hours online, abnormal knowledge more timely

Some friends may say that they can see all of them, even if they use cat's eyes. Cat's eye can see, but you can't lie outside the door 24 hours a day, can you? If someone throws a garbage at your door, or a thief stealthily draws a mark, you hear the sound and then look out with cat's eye. Can you see it?

Definitely not.

But it's different from the smart doorbell. You stay outside the door 24 hours a day. If someone passes by, the smart doorbell can immediately record a video and directly push this video to your mobile phone. You can know the situation outside the door even if you stay at home! Is it super convenient to walk outside without hearing the sound. Most importantly, when you are not at home, you can also clearly know the "story" that happened outside your home.

In addition, the intelligent doorbell also has the function of face recognition, which can capture the faces in the picture, and identify family members, friends and strangers through intelligent learning analysis. The recognition rate is as high as 99.9%, reducing the disturbance of frequent push messages, and ensuring your property safety at all times.

Installation reason 3: remote visual call to see people outside

When someone presses the doorbell, you can also have a high-definition video call with someone who is thousands of miles away. If you are a stranger, you can ask what the other party is up to; if you are a family friend or a cleaning aunt, you can also share the temporary authorized key of the smart door lock to the opposite party.

In addition, in terms of standby time, according to the experimental detection, trigger 15 times a day and record 15 seconds of video each time. The smart doorbell D1 can last for 8 months. Surprise, surprise, surprise!
