First impression of Xiaomi Dafang
What's in the box
The scope of delivery of the Xiaomi Dafang surveillance camera is overall clear. Contained are next to the camera even a 1.8 meter long Micro-USB cable, AC adapter with NEMA-1 connector (5V - 2A), as well as a Manual in Chinese.
Design and workmanship
The Xiaomi Dafang is a laureate of the "Reddot" Design Awards. Compared to other surveillance cameras, Xiaomi does not go back to the typical "dome design", but takes a slightly different approach with the rectangular "block design". With Dimensions of 12.75 x 6.60 x 6.00 cm and a Weight of 249g The Xiaomi Dafang is a comparatively compact surveillance camera, even if it is not as compact as one Yi Home Camera 2 or Yi Dome, The quality of workmanship of the surveillance camera is not objectionable and does not suggest any product from the low price segment.
As so-called "PTZ Security Camera" The Xiaomi Dafang offers one 360 ° pan function (Pan) and also lets itself around Tilt 93 °.
Built up the camera is as follows: Front is the camera module with a wide Field of view of 120 ° and a F2.3 aperture, Around the module are located 6 infrared LEDs (940 nm)that allow night vision. Videos are recorded or transmitted at a maximum resolution of 1080p (1920 x 1080). The wireless transmission is done by a 2.4 GHz WiFi module.
Also located on the front side underneath the camera module is a Status LED and an light sensor, The back form the Loudspeakers, One USB Type-A female and a sticker with system-specific information.
You can place the Xiaomi Dafang standing, but also hanging. For this purpose, the surveillance camera is equipped with a base on the underside. A firm footing is achieved by the rubberized surface of the base. At the same time the pedestal is with a ¼ inch thread equipped so that mounting with a universal bracket is not a problem. Furthermore, there are on the bottom one MicroSD memory card slot, One Micro USB socket for power supply (Power consumption DC 5V - 2A), one Setup button As well as the Microphone.
Xiaomi products are often intended for the Asian market only. For this reason, one usually only gets a Chinese user manual, which makes the commissioning seem extremely difficult, at least at first glance. Light into the darkness, however, brings so-called "Mi Home" app, which is responsible for the commissioning and operation of almost every Xiaomi product. An advantage is the multilingual structure of the app, which is why English as user language choose. The app is available for both Android and iOS mobile devices. To use the app will be a "Mi Account" needed, which you can easily create via the app.
The commissioning of the Xiaomi Dafang surveillance camera is done in a few steps. Within the Mi Home app you will be guided step by step through the commissioning with English instructions and additional pictures. The voice prompts of the camera are in Chinese. The user interface especially of the Xiaomi Dafang app plugin is only partially translated into English!
Functions and control
The Mi Home app is the control center of the Xiaomi Dafang surveillance camera. Without the app, the camera can not be used! A web interface does not exist and it is also not possible to address the camera via ONVIF protocol or to access an RTSP stream.
However, it might well be possible to implement the RTSP protocol retroactively. Unofficial firmware versions or hacks other Xiaomi surveillance camera have already shown that subsequently the RTSP protocol can be implemented and SSH, FTP and Telnet can be activated. If you want to stay up to date, you should definitely Repoarticle) keep an eye!
Cloud and offline connection
To connect via Mi Home app to the camera, will by default requires an internet connectionwhich then connects to the cloud. Data exchange with the cloud is encrypted in both directions. The servers are in China!
Alternatively, it is also possible a Direct connection to Xiaomi Dafang manufacture. For this purpose, the surveillance camera builds up its own WLAN. A Wi-Fi password can be set individually, but the SSID is not. In addition, the SSID can not hide. The encryption follows the WPA2 PSK security standard. There are no functional differences between the two modes. The only option is to store recordings directly in the cloud, which is understandably not available in "offline mode".
If you have established a connection to the camera, you are first on the home screen, about which the Live image output he follows. Already here it is noticeable that the Xiaomi Dafang plugin is only partially translated into English within the Mi Home app.
Nonetheless, most functions are self-explanatory and can be accessed with just a few touches. Via the start screen it is possible to trigger the video or photo recording function and to monitor the transmission quality. Video recordings are stored directly in the cloud, on the smartphone or on the SD memory card. It is also possible to shoot in the loop To make, ie as soon as the memory card is full old recordings are deleted, as well as recordings can be automatically in Network transfer and save. Underneath the live image output are function buttons for voice transmission, speaker, full-screen mode, and memory card access. Also on the home screen is a control padwhich allows the surveillance camera to be moved horizontally and vertically at the push of a button.
The Xiaomi Dafang is a surveillance camera with PTZ function. PTZ stands for "Pan-Tilt-Zoom", The Dafang can be rotated by 360 °. An inclination is possible around 93 °. The existing one Zoom is digital and can be controlled by swiping the live image output.
Motion input via the directional pad is taken over with a delay of about one second. The movement itself is rapid. A complete 360 ° rotation takes about 5 seconds. The engine is audible, however, the volume is still acceptable, so that the surveillance camera can be used easily in the sleeping area.
Stand for an automatic movement different movement profiles to select. Among other things, there is one Motion Tracking, that is a motion detection that detects movements in the image area and follows them. Only movements are detected, not faces! For example, if the camera detects movements in the leg area, it is quite possible that the head is no longer in the picture. If several people or objects pass through the image, the Xiaomi Dafang can quickly be disturbed. The camera does not know which person or object to follow and jumps between several trackable people or objects back and forth.
Another mode is the "Cruise Mode", The surveillance camera automatically shuts off 4 positions. An individual range of movement or own positions unfortunately can not be determined. in the "Timelapse mode" The security camera creates a time-lapse shot. At what intervals and over which period images are to be recorded is configurable.
Overall there is 3 alarm trigger, Trigger 1 is the motion alarm, As soon as a movement in the image area is detected, the alarm is triggered. The sensitivity of the motion alarm and the period during which the motion alarm is to become active can be configured individually. Furthermore, the Xiaomi Dafang is capable of one smoke alarm and one CO alarm trigger. In doing so, it recognizes the alarm sound of common smoke and CO detectors and thereby triggers its own alarm. Alarm notifications are sent as a push notification to the mobile device. A notification by email or SMS is not possible. The created video clips are stored in the cloud and / or on the inserted SD memory card, depending on the connection mode.
The voice transmission works in both directions. On the one hand, the camera has a microphone installed so that the sound can be transmitted from the camera to the mobile device, as well as the camera has a speaker, so that sound from the mobile device can be played via the surveillance camera. The sound played through the camera's speaker sounds slightly tinny, however, is understandable. The sound recorded by the camera is still understandable even at a range of just over 10 meters.
Timeline lets you easily recall the recordings stored on the SD memory card. The recorded period is over the time beam to the second exactly traceable and retrievable. Individual video sections can be sent to the mobile device and shared.
Devices integrated into the Mi Home app can be accessed via so-called "Scenes" or "Automations" being controlled. With the help of If-statements (if> then) can be individually determined how the Xiaomi Dafang behaves in certain events. Among other things, it can be set to turn the camera on or off after a timer, call, SMS or weather event, enable or disable the alarm, or save a clip in the cloud. It can thus create numerous individual scenes and also integrate different Xiaomi smart devices. The only downside is the (mostly) Chinese user interface.
The settings menu is divided into general settings and more specific camera settings. In the general settings Among other things, the camera name can be changed, a PIN protection can be specified, firmware updates can be called up and the network status can be viewed more closely. About the camera settings can manage the alarm function, you can regulate the night vision mode, the aspect ratio of the recording can be changed, the status LED can be turned off and there is the possibility via the camera settings to enable the offline mode. Unfortunately, there is no way to change the time zone of the camera!
The Xiaomi Dafang takes videos at maximum 1080p (1920 x 1080 pixels) resolution and 15 images-per-second on. By the Wide angle of 120 °, you get a particularly large image detail that covers a room well.
Recordings convince by one pleasant detail with low noise, Compressed video footage with the H.264 codec, The output format is MP4, The video bit rate is an average 320 kbit / s. Due to the low bit rate image artifacts are not uncommon. Especially with rapid PTZ movements and movements through the image, the artifact formation is clearly noticeable. Although the recording quality is not excellent, people or objects are still well captured. At the same time, the memory is spared, because a one-minute video recording is just once 5 megabytes in size!
When the light is dim, the security camera switches to the standard mode Night vision mode, Alternatively, it is also possible to switch the night vision mode on or off manually. The sensitivity of the light sensor can not be regulated. Active night vision mode also increases the amount of noise. Movements are still detected in night mode.
The transmission quality of the stream is still acceptable according to the price. The video signal is transmitted, if one is with the camera in the same WLAN only slightly delayed. It looks worse with the Remote Access out. If, for example, you would like to access the camera via the mobile network, you must first establish a connection to the cloud, which in turn must first receive the video signal from the camera. The servers are located in China, which in turn leads to major delays. On average, it takes 5-10 seconds for an action to be taken over the remote connection.
The power consumption of Xiaomi Dafang is in Idle at 6.5 Watt, Once the camera is with the Cloud synchronized, the consumption increases 8.6 Watt at. Will one PTZ movement executed, the consumption is included 10.5 Watt.
