[Heart Harbor]

Home is out of the house, my heart is worried;

Home is a cold winter, the warmth of the heart;

Home is the reunion of hearts as the Spring Festival approaches;

Home is the harbor of the soul.

Are the doors locked and the windows closed? What are the family doing?

There are elderly parents, beloved ones, lovely ones and cute ones at home... you are always worried about wandering outside.

Don't worry about my dear friend, Dr. Peng has recently launched the Smart Home π family security suite, which is not only easy to install and has clear images, but also has intelligent joint defense, infrared night vision, remote control and other functions to help you master the situation at home at any time.

[Concentrate]

Dr. Peng Intelligent focuses on providing professional intelligent security protection asset service products and indoor environment intelligent control products for families and enterprises. Relying on the full support of the parent company Dr. Peng Telecom Media Group and years of intensive work in the field of network security and safe cities, it has incomparable network resources, strong data processing ability, strong after-sales ability of products and stable supply.

[Don't follow the routine]

Every detail of Dr. Peng's design reserves space for users to use their imagination and creativity. In this case, we might as well put aside the routine of conventional evaluation and analyze the actual effect in combination with product details. First, let's take a look at the complete set of household security equipment, including: Genie camera 1.0G, door and window closing detector, human movement detector, camera transformer, power cord, etc. Each product has a separate manual, and the manufacturer has introduced each detail very completely, which will not be repeated here. The accessories are also very considerate. The two sets of batteries, card reader and mounting screws of the detector have also been prepared.

[Central Gateway]

The 1.0G smart detector head is exquisite and has the following figure (101mm high, 62mm wide, 50mm base and 112g weight). It is not only a camera device, but also a central gateway for other devices to obtain connection and transfer data. The device can be bound by scanning the QR code at the bottom of three products through the mobile phone client. This leaves a lot of space for the design of the entire home security. Each user can design a home system according to their own needs and manage the devices in groups.

[Intelligent Storage]

Dr. Peng can not only watch the live broadcast at home online, but also store the video in the cloud. He can also save the video in the TF storage card cyclically, supporting data offline storage. Even if there is no network at home, important information can be recorded (the memory card will be automatically overwritten when it is full, and the data will be saved in scrolling mode) for users to check when they go home. In order to better record the pictures you need, you need to adjust the trigger conditions of the camera and insert a TF card with larger storage capacity (more than 32G is appropriate).

[Random rotation]

The lens and the base are connected by a round head rod, which can rotate 360 degrees horizontally, 120 degrees back and forth, and swing about 30 degrees left and right. The 2D code image on the base of the smart camera is surrounded by a black anti-skid circle, and a circular magnet is below the black anti-skid layer.

[Magnetic chassis]

The built-in magnet on the base has a strong adsorption capacity, which can be firmly attached to various iron appliances such as refrigerators, air conditioners, washing machines, chandeliers, etc. at home. As shown in the following photos, there is no problem with leveling, handstand, wall hanging or ceiling mounting, and they will not shake or fall off.

So, the problem has come - since Dr. Peng's camera can be placed in so many places, how to solve the problem of power supply and wiring? Do you want to add a camera power cord or patch panel to your home?

[Convenient power supply]

To solve the above problems, first carefully observe the power supply design of Dr. Peng's camera. Different from the transformer power line supplied by other brands, Dr. Peng adopts a separate design, and the interface uses the most widely adapted USB Micro USB, which not only makes the product more compatible, but also leaves a lot of creative space for players.

[Creative Play]

As shown in the following picture, the power supply can be solved by mobile power supply. The smart camera has low power consumption. The conventional 10000mA power supply can guarantee its uninterrupted operation for several days (turn off the indicator light to save energy), which can solve the aforementioned problems of wiring and power supply. I hope that the students who have read this post will use this method in the right way, and do not have evil thoughts!!! In order to guide the readers correctly, I briefly introduce two creative play methods: 1. Investigation car; 2. Poisoning sound bomb.

The reason for the length of the evaluation only briefly introduces the car structure, which is similar to using a single chip computer as a reconnaissance car. Put the mobile power supply (Wan'an mobile power supply weighs about 100g, and is fixed with cold gel) and the smart camera on the remote control car, and cooperate with the WiFi or mobile phone hotspot (outdoor) at home to form a remote detection car (please do not use it for peeping). It has been tested for everyone. Choose a remote control car with fast speed and quiet sound. Remember to put lubricating oil on the motor first, so that if you play, you will not be caught. Students who have stepping motors can make camera rotating discs by themselves.

[Infrared night vision]

Dr. Peng Smart camera adopts full glass lens. Compared with the black camera of a brand in the above figure, it is more convenient to wipe without worrying about the lens being blurred; 2.3 Large aperture can obtain greater light flux. Even if the ambient lighting is insufficient, the captured image is still clear and not easy to blur. With 10 850nm infrared lamps, each detail of the image can be clearly captured even in a completely dark environment.

[Clear call]

The author has used Hikvision, Epedo and many other brands of smart cameras of different models. The first thing I feel when summing up the experience is not the picture quality, but whether the call is clear. As shown in the figure below, the distance between the speaker at the upper end of the camera back and the microphone at the lower end is not more than 4 cm. Although the speaker at 8 Ω/1 W is not large, the call is clear without echo.

[Human body detection]

In order to enhance the ability to capture moving objects, and to reduce misjudgments and improve the accuracy of human body recognition, this security suit naturally needs human body detection devices. Dr. Peng's intelligent human body mobile detector uses infrared thermal radiation to sense the human body, and transmits data through the smart camera gateway as described above. The power consumption is low, and two No. 5 batteries can supply power for more than half a year. When the power is low, it will automatically remind the client.

Dr. Peng's intelligent human motion detector has strong anti-interference ability, and can accurately judge the volume of infrared objects to eliminate false alarms brought by pets. Although the official standard configuration of double-sided adhesive tape allows the detector to be ceiling mounted and wall mounted without damaging the wall, since it is a sensor, it should be hidden. There are good reasons for its small size and good concealment characteristics to be placed in the corner of the shoe cabinet, door frame, etc., and integrated into various home environments (as shown in the photo below, placed in the corridor potted shadow).

[Doors and windows closed]

This detector adopts the principle of electromagnetic induction, and uses the change of magnetic field to form a current signal to judge whether the doors and windows are closed. The author did not put it in the window according to the instructions, because there are too many windows at home, but suggested putting it in the cupboard to judge whether the cupboard for important items at home was opened. It can also be placed next to the iPad and game controller to see if the child has played games secretly. Please note here that the detector should not be too far away from the camera, or the signal cannot be transmitted through the gateway.

[Clear and optional]

Dr. Peng's design is based on the different use environment of each family: indoor, daytime, outdoor and night four modes. At the same time, the definition can be adjusted according to the installed network speed and the need for image clarity. Dr. Peng provides three kinds of definition options: high-definition (1280x720) standard definition (720x405) smooth (352x288). The following group of photos is a comparison of three kinds of definition effects of the same scene (the original image is clearer after screenshots are compressed). It can be seen from the pictures that the height of the pictures taken in different definitions is the same. The difference lies in the width and resolution of the pictures. The picture size is wider in high-definition mode. If the network speed allows, high-definition still looks comfortable.

[Effect Comparison]

In addition to the above mentioned picture definition and width, there are also color restoration, contrast and so on to evaluate the camera effect. As the amplitude of the picture is relatively large, there is no way to talk about it without contrast width and narrow. In order to make people feel more intuitive, you can use two cameras to make a comparison. Since the horizontal review is about to find a strong opponent, the author chooses to use the intelligent camera of Epedo, which used to be expensive, as a sword test stone.

From the following group of photos, we can intuitively feel that Dr. Peng is much higher than similar products in terms of picture quality and picture range, more accurate color recognition, no color deviation in the picture, and the picture height and width are much higher than the comparison products (the maximum support of the comparison model is 720P). According to official data, its picture angle: horizontal angle of view is 90.8 °, vertical angle of view is 49 °, and diagonal angle of view is 112 °. This data is close to the width of residual light of both eyes.

[Joint defense cooperation]

Dr. Peng not only has better picture quality, but also the smart camera is only an integral part of the home security system. The whole equipment has accessories such as door and window closure, human movement detector, etc. In the future, external devices (such as Dr. Peng's intelligent environment kit) can be expanded as needed at any time, creating a large space for expansion. Compared with the traditional camera, Dr. Peng's equipment is group warfare.

[Multiple security]

There are many highlights in the design of Dr. Peng's software, such as the free setting of joint defense deployment and control, the indicator light can be turned off, the division of virtual rooms, etc., because the instructions have been very detailed, there is no need to repeat. But one of the highlights has to be mentioned, because it is the first time to see such multiple security protection designed after playing with so many cameras.

First of all, the device QR code mentioned above is bound. Each device can only be bound by one account. Second, the device has an independent password, and the system reminds you to change the initial password. Third, the mobile client needs to unlock the graphic password every time it is used. Fourth, you can share the device with family or friends, but only for mobile phone numbers, and you can set the sharing time limit.

[Experience summary]

I looked for him thousands of times in the crowd. When I looked back, the man was in the dim light. In order to keep track of the situation at home at any time, the author has also gone through thousands of mountains and rivers to look for, and thanks to the ZNDS crowd test for giving Dr. Peng the opportunity to experience the smart and safe living π family security suite in this issue. There is no rhetoric and no need to stack data in this issue. Through truthful demonstration of the actual use effect and objective and pertinent horizontal comparison, I believe that everyone can judge the good and the bad, and have a new understanding of Dr. Peng's set of products. It is recommended to start with families in need, so that your warm home can be protected safely.

[Optimization suggestions]

1. Adjust the detection sensitivity of door and window closure to reduce misjudgment;

2. Use a slightly more powerful speaker to enhance the sound effect;

3. A stepper motor for the rotary camera is added to the base.
