Le Orange is a smart device brand under the Dahua Group. Its products include TV boxes, smart cameras, childcare robots, and care monitors. After the introduction of the Xiaole voice video parenting robot and baby care device in the field of intelligent and voice interaction, Le Orange put the voice interaction technology back on the smart camera and launched the Le Orange TC5S smart camera with the main voice interaction.
Packaging and accessories
Le Orange TC5S is packed in white carton and has production information on the side. It is stacked, the first layer is the machine body, and the lower layer is various accessories.
In addition to the warranty card, the accessories include power supply, micro-USB data cable, screws for wall fixing and accessories. The manual connection and usage tutorial is very detailed, and the output of the charging head is 5V/1A. The actual measurement can be powered by a conventional mobile power supply. That is to say, the machine can be used outdoors, and if the wireless hotspot is not opened, the TF card can be inserted, and the machine's mobile monitoring, infrared night vision and other functions can be directly turned on.
Appearance and workmanshipLe Orange TC5S adopts the more common drop-shaped design of home smart cameras, but the base and body parts are more angular than similar products. The front of the base has only the product logo, and the design is very simple.
A full circle of black around the camera is the shade of the night vision infrared light. The camera is equipped with Sony's 1/2.9-inch CMOS. The 170-degree ultra-wide-angle lens is destined to protrude like a fisheye lens, which is matched with the polished material of the whole body. Can improve the machine's face value and grade, but usually pay attention to maintenance.
The back of the fuselage is very round, with the speaker opening at the rear, the reset button for resetting in the lower right corner, the TF card slot on the left, and the micro-USB port for power supply at the bottom. More special is that Le Orange TC5S is equipped with a bilaterally symmetrical dual microphone array, the openings are placed symmetrically on both sides of the fuselage, its use will be detailed below.
The SN code and MAC address of the machine on the base, and the QR code used to add the device.
The base has a counterweight and a non-slip mat. The spherical joint can greatly adjust the angle and pitch angle of the lens, and the degree of freedom is very high. Without the use of glue and wall-mounted base, the maximum tilt angle supported is around 45 degrees (if it is too low, it will fall _(:з"∠)_), the overall damping is slightly too large, and the hands can only be twisted by the hands. If you accidentally knock it down, it will not change the angle of the base, it is very stable.
The biggest feature of smart cameras is that they can be connected to mobile phones. Nowadays, the commonly used solutions in the industry are nothing more than "scan code / LAN search - wireless / acoustic transmission wifi password data". In order to ensure safety, Le Orange TC5S has chosen a slightly more step-by-step scheme to scan the QR code at the bottom of the fuselage - enter wifi account information - transmit wifi information via sound waves - enter the security code at the bottom of the fuselage before accessing, sound waves and security Codes are relatively rare settings in their class.
Le Orange's smart cameras all use the "Le Orange" client. The app home page is "Camera picture list, alarm message, public live discovery channel, personal settings", and provides four-square grid multi-camera preview. If there are multiple cameras, You can have a 4-square preview as you would a monitor.
The interface and design are similar to those of fluorite, Lenovo, ZTE, Yunhe and other similar products. The difference is that Le Orange has added many advanced functions such as mobile monitoring sensitivity, humanoid monitoring, and monitoring area to the mobile phone client, and also supports direct voice intercom function.
Wide angle / picture quality / infraredAs a camera, the core is still the picture quality. On the hardware, the Le Orange TC5S and the Le Orange TP1, which we have also measured before, use sensors that are not the same as the same price products. The decoding chip and sensor materials are very hard. The Le Orange TC5S is a Sony Exmor series 1/2.9-inch CMOS with a total pixel count of 2 megapixels and a maximum of 1920*1080P video.
Its unit pixel size makes it easy to kill all mobile phones in active service. Now part of the flagship mobile phone's top sensor, although using ISOCELL pixel grid technology and optical image stabilization, but the 12 million pixel sensor on the iPhone 7/7 Plus Only 1/3 inch, the unit pixel is only 1.22μm, and the 1/2.8-inch IMX298 on the Xiaomi 5 is 16 million pixels, and the unit pixel is only 1.12μm.
In terms of lens, Le Orange TC5S uses a universal M12 lens interface super wide-angle lens with a focal length of 2.1mm. The actual imaging field of view reaches 170 degrees diagonal and 130 degrees wide. Corresponding to the ultra wide-angle lens is the LDC real-time distortion correction technology, which can alleviate the wide-angle distortion of the main body of the picture to some extent.
The same is to ensure the viewing angle and discriminating power at the same time. The TC5S's super wide-angle +1080P scheme is just two different routes from the previous TP1's small viewing angle and high resolution. If you haven't played a driving recorder or a fisheye lens, you will be very shocked when you first see this wide angle. The viewing angle is several times larger than the common mobile phone.
In actual use, it is already in the shooting range less than 10cm in front of the base. The paper towel and water cup next to the machine are in the mirror. Just find a desk or a cabinet, even if it is only 10 square meters of small space can be fully photographed.
Le Orange TC5S's LDC real-time distortion correction technology has obvious correction effect in the perspective, mainly for the edge of the picture, and the deformation in the center of the picture is similar to the conventional focal length lens of Note5. The wide field of view from the wide angle is mainly concentrated on the edge. Although the overall fisheye effect is more obvious, the edge deformation of the object is not obvious. The overall wide-angle effect is excellent, and the edge degradation control is also good. Of course, this may be related to its own low pixel.
In infrared night vision, if the infrared light is too powerful, it will affect the effect due to the reflection of nearby objects, while the power is too small to touch the other side of the site. Between the indoor effect and the infrared power, the choice of Le Orange TC5S is obviously the former. With an infrared distance of 7 meters, it is suitable for living in the mainstream living room and room. It may be a little difficult to deal with a mansion with a depth of 10 meters.
In actual effect, although the near-infrared reflection of the object is obvious, but because the power is not too high, it will rarely cause the whiteness of the picture. The actual distance is enough to illuminate the wall of 9, 10 meters, and the performance is consistent. expected.
Tolerance: The sensor of Le Orange TC5S is already a big "bottom" in front of the mobile phone. It has a high tolerance. It looks like the HDR effect in the daytime, and it can retain a lot of dark details.
Metering: The metering strategy of the Le Orange TC5S metering direction is very obvious, just to see as much detail as possible. The indoor metering is very close to the Note5 test; in outdoor glare, the metering is turned down to keep the details of the highlights; in the low light, in order to see more details of the shadows, the metering will be similar to the Samsung S7 edge. Bright
White balance: Le Orange TC5S overall white balance is more accurate, there is a slight yellowish green tendency, the white balance under indoor fluorescent light is even closer to the naked eye than the style of Note5 deliberately warmer.
Sunrise low light scene (outdoor light is too weak, but reflects the shadow of the fuselage)
Low-light imaging and noise control: In addition to latitude, the outsole sensor has the advantage of ISO sensitivity. In the low-light scene at the junction of day and night, the picture quality will not drop too much, and the noise control is amazing. It is also very ironic to say that many thousands of pixels of the thousand yuan machine, very weak light discriminating power and Le Orange TC5S can not pull the distance.
Le Orange TC5S equipped with Anba S3LM graphics processing chip, using H.265 encoding, has certain advantages in video compression, can save bandwidth and storage space. It is smaller than the speed requirement of similar products, but after all, it is still 1080P resolution, the bandwidth demand will be 40-50% higher than its own 720P product, and the network speed consumption in HD preview is about 100-120k/s. between.
Le Orange is expanding from the security and camera fields to the field of artificial intelligence and interaction, and has launched a voice interactive video parenting robot and baby care device, while the Le Orange TC5S can be seen as a field of voice interaction and artificial intelligence back to the camera. The first product. The official promotion of Le Orange to Le Orange TC5S is “can talk†and has added special voice interaction optimization.
On the hardware, the machine is equipped with a dual array microphone that recognizes the user's voice commands within a distance of 1.5 meters. What's more, the Le Orange TC5S has an all-weather voice recognition standby capability. You can directly perform the corresponding operation by simply saying "trigger command" at any time.
Long-distance voice and all-weather standby require microphone arrays and specialized chips. Even in the mobile phone field, only a handful of flagships have such capabilities. Previously, only dedicated home voice assistants such as Amazon Echo and Google Home had these features. The difference between Google and Amazon is that the product is made into a stereo, while Le Orange is placed on the camera.
Function: Although the product use scheme is relatively mature, Le Orange is very restrained in function (in order to simplify the interaction as much as possible?), the key functions added on Le Orange TC5S are only voice weather query and video message. The video message in the middle will send the 15 pictures and sounds after the voice prompt to the mobile client. This sounds a bit pity, but the official obviously chose to focus on ensuring the availability of the two highest-frequency functions of weather inquiries and voice messages, greatly reducing the threshold for use, and the elderly can operate without learning, or even as A special version of WeChat that requires no additional operation and maintenance, just put the machine at home and use it.
Trigger command: The trigger command of the weather is "Today's weather, tomorrow's weather", the video message command is "I want to leave a message", very simple and rude. No matter how long the voice is before and after, it can be triggered as long as it contains a trigger command. Mistakes, because normal life rarely uses these two four words near the machine, the machine has not been touched on the desktop for more than a week.
Identification distance and environmental adaptability: measured in a normal office environment that is not very quiet, the machine can hear and recognize the normal volume command at 2 meters away, and the standard of Mandarin is not high, as long as it is not too fast, The machine can recognize it. It is the product that the author has encountered the lowest voice recognition distance and volume requirements. This is indeed a bit of black technology.
The format of the weather broadcast is "Shenzhen, January 10, 2017, cloudy, no continuous wind direction, the highest temperature is 23 degrees, the lowest temperature is 20 degrees", and the video message will prompt "Message after a bang", complete 15 After the second is sent automatically, the mobile phone will immediately receive the relevant push, you can directly view it when you click it. The availability and practicability of the two functions are very high. If you want to say the problem, the voice announcement of the machine has no volume adjustment option, and you can't interrupt it during the broadcast.
In addition to voice interaction, Le Orange TC5S screens can be shared live on WeChat, Weibo and QQ space. If you want to broadcast live on Le Orange's own public number and H5 page, you need to pay for it. It should be exposed in the app's discovery section. You only need to apply, and you don’t have to wait for the length of time and the number of visitors.
There is also a very low-key function improvement. The Le Orange TC5S supports humanoid detection, which can only retain the recognition of humanoid objects. After all, if you only use it in your home environment, you only need to check if someone is moving. In the same environment, this function can greatly reduce the chance of false triggering. In the office, the invalid notice can be reduced by more than 60% in the day. In the past, the camera often took Xiaoqiang who climbed the table in the middle of the night and alerted me. I won’t tell you...
to sum upLe Orange already has several cameras such as TC, TP, baby caregiver or a product series closely related to the camera. It has made very few mistakes in hardware and software. The TC5S is a very intelligent camera even without voice interaction. The latitude, low light performance and video compression ratio of the outsole sensor and Ambar chip solution are significantly improved. As the main selling point of TC5S, the voice interaction is very high in the actual experience. Le Orange has done a very simple and restrained function and use method. This is not only technology, but also needs to overcome a lot of internal pressure.
