……

Maybe this one WiFi HD Baidu Cloud Camera - Xiaohei i Ear and eye love can help you with obsessive-compulsive disorder.

Xiao Hei i Erotic eyes Simple operation, convenient installation, real-time intercom, cloud storage, cloud push.

Next, let's talk to Vitas Let's see Xiao Hei i What is the specific performance of love for ears and eyes.

[Packaging, details, disassembly 】

Xiao Hei i Aimu's white cuboid box is standard. Vitas got a black "limited edition" with complete package. Why is it called "Limited Edition", continue to see below.

The trial equipment consists of the first media of mobile Internet intelligent terminal Lei Feng Yes.

▲ i Aimu packing box is based on the concept of family use.

▲ i All items in the Alem box. Data cable, camera, main frame and base.

The small black package obtained by Vitas is complete and normally sealed, but there is no manual, certificate of conformity, warranty card, etc. inside. Although it is of little use to Vitas, the QR code, download address, and WeChat public account are all behind the box, it will be confusing for parents who are slightly older and have little access to such equipment.

Through and i The technical engineer of Aimu Technology Co., Ltd. contacted to confirm that there are instructions, etc., which may be missing. Later, it was found that only three of the four high attraction magnets on the base were installed (see the following figure for details)—— The rhythm of winning the prize and the limited edition of Xiao Hei are in my hands. Have you ever bought instant noodles without filling bags or with more?

If it is caused by non mass production engineering testing machine, it is acceptable. Either @ Is Elmer Technology Co., Ltd. considering improving quality control!?

Suggestion: whether the camera body can be sealed with a plastic bag before being stuffed into the box. After vibration and friction, the black bracket has blackened the white part of the box, affecting the user's first impression. Moreover, if the packaging carton is damp, it may affect the camera circuit components.

According to the actual measurement, the length of the cable is 2.0 meters, so it can be lengthened appropriately, because not all the small black cables will be placed on the desktop or adsorbed on the refrigerator panel. The cable is commonly used for Android charging Micro USB interface, but the plug is a little short. It is a bit "beyond reach" to charge the mobile phone with Xiaohei's own cable. That is, Xiaohei can use other general The micro USB interface provides power for it, but its own 2.0 meter cable may not be able to supply power for other devices.

▲ The circular design of the base is made of metal materials, which makes it feel very reliable when you get it, and the edges and corners are handled very carefully.

The base can be fixed with bolts or attached to the metal surface with high-performance magnets at the bottom. What we should commend here is the strong attraction of the base. Although one high magnet is missing, it is enough for Xiao Hei to be fixed in various positions.

▲ Xiao Hei's height.

Xiao Hei- i Erotic eyes It is a video monitoring equipment launched by Beijing Aimu Technology Co., Ltd. for the civil market to meet the personal and property security needs of families and companies And the future of video sharing and entertainment Ask. High definition wireless network camera provides the public with safe and real-time audio and video monitoring services based on Baidu Cloud.

Beijing Aimu Technology Co., Ltd. is known as the pioneer of professional cloud cameras in China, the first enterprise to develop and launch real cloud cameras in China, and also the equipment supplier of telecom cloud home monitoring.

▲ Here, we should praise that the round head angle of the bracket is adjusted well, and the damping of rotation at various angles is obvious, and the strength is just right. The disassembly and insertion requires a little effort and is not easy to fall off.

▲ Actual measurement of main part: diameter 61mm, thickness 36mm, weight 56g.

▲ After disassembly, we can see the audio intercom speaker (left) and the round PBC motherboard.

▲ Disassembly, camera 2.8mm IR 1/2.7 provides high-definition video recording up to 720HD.

▲ Disassembly, internal work.

[Application performance]

Xiao Hei- i Erm cloud camera can It is easy to monitor the real-time videos and historical videos of your apartments, villas, shops, factories, offices and other places. Through the "Cloud Netcom" alarm cloud push service, you can instantly receive the abnormal information of the places you are concerned about. Through Baidu Cloud storage service, you can save the monitoring images in real time and quickly share them with friends. Let's take a look at some possible use scenarios:

▲ For home use, it is easy to place it opposite the subject to be monitored, without memory card, and is not afraid of card full frame break. If someone enters the home and the monitoring screen changes, the mobile phone software will immediately take a screenshot and send you the live image and sound.

▲ Like a bat, suck it upside down on the metal lamp holder to monitor your every move. Or you can attach Xiaohei to the metal panel of the refrigerator facing the entrance door (window).

▲ Monitor the electric vehicles and bicycles in the corridor, as well as the suspicious people who are waiting for opportunities to steal sheep.

▲ Of course, as long as there is a WIFI signal, teleconferencing is also completely competent.

▲ Working current test: the working current in normal light room is 0.28A.

▲ Working current test: cover the camera and photosensitive acquisition area, 12 low light Infrared LED starts and works The current is 0.40A.

▲ It is truly wireless. The power is supplied by a 1800mA simple charging bank, and the small black base has sufficient suction force to support it. The WIFI signal can also be found at the door, and the communication is normal.

According to the maximum working current of 0.40A in the previous test, after conversion, the charging bank of a single 18650 battery can supply power to Xiaohei for 4 hours.

▲ If you want Xiao Hei to do more, farther and more wireless. It is matched with the Home type power bank routing as shown in the figure above, with built-in 3G and 4G network cards. It can provide USB power supply WIFI for Xiaohei at the same time. In this way, Xiaohei's lethality is huge, and you can use it to monitor, secretly shoot and eavesdrop anywhere! There will be delay when using 3G signal video.

▲ The maximum temperature of Xiaohei after 4 hours of continuous use is 46.5 ℃, and the indoor ambient temperature is 21 ℃. Continue to monitor that the temperature does not rise.

▲ Real time face change transmission, The 720HD image is clear enough to enable the infrared LED under low light conditions, which can only provide black and white conversion.

▲ The highlight of Xiaohei-i Ermu is the change of picture and sound detection Cloud push ： Push the alarm information to your mobile phone in real time through Baidu Cloud Push.

How does this work?

The so-called image change area alarm is to define some areas within the camera's view range, and generate an alarm when illegal intrusion occurs in this area. In this way, the key areas can be effectively monitored. The target is represented by a rectangular area, which is judged by analyzing the change of the image gray value of the target area.

1. Collect the first picture, calculate the gray value, and save the gray value.

2. Collect the second picture, calculate the gray value, compare it with the gray value saved last time, calculate the gray change direction, and save the change direction, which includes three cases:

-Gray scale unchanged

-Greyscale

-Diminish grayscale

Use the gray value calculated this time to cover the gray value calculated last time.

3. Collect the third picture, calculate the gray value, compare it with the previous saved gray value, calculate the gray change direction, and judge it by combining the previous gray change direction,

If the gray level change direction of this time is different from that of the previous time, it indicates that the target area has changed and an alarm should be generated. That is:

-The gray level becomes smaller this time, and the previous gray level becomes larger, generating an alarm.

-The gray level becomes larger this time, and the previous gray level becomes smaller, generating an alarm.

-The grayscale remains unchanged this time, and no action is taken.

-The previous grayscale does not change and does not act.

Based on this principle, Xiaohei - i Aimu pushed the screen changes through Baidu Cloud, and transmitted the screenshots to the App mobile terminal to generate an alarm, reminding to check the scene in time.

▲ Xiaohei - iAimu has made a great breakthrough in civil home monitoring. In addition to inheriting the main functions of traditional cameras, it also has functions that traditional cameras do not have, such as remote control, notification cloud push, data cloud storage, synchronous voice, video cloud playback, and so on. Combining network and cloud, Xiaohei has a sense of technology.

▲ It needs to be configured with the mobile terminal and connected to WIFI for the first time.

It is worth mentioning that the purchase of Xiaohei-i Aimu will provide a free one month Baidu Cloud service, which will be charged after one month of activation. 14.9 yuan per month. The webcam function of Baidu's cloud service can still be used without buying it, but cloud storage and playback are not available.

▲ Mobile app and interface, you can press and hold the talk button to chat with the video on the other end of the camera.

App settings are simple and easy to operate, and the alarm sensitivity of screen changes can be adjusted. It can also be cut and shared according to the cloud playback video.

▲ Find a complex scene, place my car in the video monitoring area, simulate illegal movement, set the highest alarm sensitivity on the App, and the mobile phone successfully alarms to achieve the desired effect.

[Highlights and shortcomings]

Highlights:

▲ Beautiful and fashionable appearance, excellent workmanship.

▲ The base has strong attraction and moderate corner damping feedback.

▲ Baidu Cloud Storage does not need to worry about full memory and malicious damage to video data.

▲ 720P HD image quality.

▲ Two way voice intercom.

▲ Convenient operation and installation.

▲ The screen change alarm function is very practical for home anti-theft.

Insufficient:

▲ The main body of the equipment in the package is not sealed with plastic bags, and the equipment may be damaged due to moisture during transportation, storage and logistics.

▲ Vitas got the missing installation manual, warranty card, certificate of conformity, etc., and the base lacked a high magnetic field. I don't know how high the rate of such "limited edition" is. We hope to improve the quality control. Don't exchange the return and express fees for a manual.

Xiaohei - i Aimu 299 has a good price performance ratio. Vitas believes that intelligent hardware should be based on the competitive consumer electronics market for a long time. In addition to innovation and breakthrough, it must also have continuous product updates and iterations to meet more consumer needs. If there is "i love eyes and ears pro" or "IErMu 2" To continue production, whether it is possible to consider installing battery modules and 4G SIM card communication modules in the base area to provide a few hours of real wireless fixed-point video recording, which may be useful for short-term security and video capture of some large-scale events or events, but will also bring about problems such as volume, weight, endurance, network stability, etc. that need to be solved by engineers. It is expected that Elmer Technology Co., Ltd. will continue to produce more and better intelligent hardware.

Try out the Xiaohei-i Ermu camera, which is provided by the first media of mobile Internet intelligent terminal [Lei Feng].
