Le Orange is an intelligent device brand under Dahua Co., Ltd. Its products include TV boxes, intelligent cameras, parenting robots, nursing monitors and other fields. After the launch of Xiaole voice video childcare robot and baby care device in the field of intelligence and voice interaction, Le Orange has fed back voice interaction technology to intelligent cameras, and launched Le Orange TC5S intelligent camera focusing on voice interaction.
Packaging and accessories
Le Orange TC5S is packed in white paper boxes, with production information on the side and stacked. The first layer is the machine body, and the lower layer is various accessories.
In addition to the warranty card in the manual, the accessories include power supply, micro USB data cable, screws and accessories for fixing into the wall. The instructions for connection and use are very detailed and simple, while The output of the charging head is 5V/1A, and the conventional mobile power supply can be used for power supply. That is to say, the machine can be used outdoors. If the wireless hotspot is not turned on, the TF card can be inserted for use. The machine's mobile monitoring, infrared night vision and other functions can be directly turned on in actual measurement.
Appearance and workmanship
Le Orange TC5S adopts the common drop shaped appearance design of home smart cameras, but the base and body are more angular than similar products. The front of the base is only the product logo, which is very simple.
The whole circle of black around the camera is the lampshade of night vision infrared lamp. The camera is equipped with Sony's 1/2.9 inch CMOS. The 170 degree ultra wide-angle lens is bound to protrude like a fisheye lens. In combination with the overall polishing materials, these can improve the appearance and sense of quality of the machine, but you should pay attention to maintenance at ordinary times.
The back of the fuselage is very round. The front rear is the speaker opening. There is a reset button at the lower right corner, a TF card slot at the left, and a micro USB interface for power supply at the bottom. In particular, Le Orange TC5S is equipped with left-right symmetrical dual microphone arrays, with holes symmetrically placed on both sides of the body. Its use will be discussed in detail below.
The base has the SN code and MAC address of the machine, as well as the QR code for adding equipment.
The base is equipped with counterweight and anti-skid pad, With spherical joints, the angle and pitch angle of the lens can be greatly adjusted, and the degree of freedom is very high. Do not use adhesive and Wall base Of In this case, the maximum tilt angle supported is about 45 degrees (if it is too low, it will fall _ (: ☒ "∠) _), and the overall damping is slightly larger. Usually, you have to use both hands to rotate the fuselage, and if you touch it carelessly, it will not change the base Angle, very stable.
App and connection
The biggest feature of smart cameras is that they can be connected to mobile phones. Now the common solutions in the industry are nothing more than "code scanning/LAN search - wireless/acoustic transmission of wifi password data". In order to ensure security, Le Orange TC5S chose a scheme with more steps: scan the two-dimensional code at the bottom of the fuselage - input the wifi account information - transmit the wifi information through sound waves - input the security code at the bottom of the fuselage before access. Sound waves and security codes are rarely used in similar products.
App main interface
Screen view
Rich settings
All of Le Orange's smart cameras use the "Le Orange" client. The home page of the app is "camera picture list, alarm message, public live broadcast discovery channel, personal settings", which provides four grid multi camera previews. If there are multiple cameras, you can have four grid previews like monitoring.
The interface and design are similar to those of similar products such as fluorite, Lenovo, ZTE and Yunhe, and they are easy to use. The difference is that Le Orange has added many advanced functions such as mobile monitoring sensitivity, human shape monitoring, monitoring area, etc. to the mobile client, and also supports direct voice intercom function.
Wide angle/image quality/infrared
As a camera, the core is still the picture quality. In terms of hardware, Le Orange TC5S and Le Orange TP1, which we also measured before, both use sensors that are different from products at the same price, and the decoding chip and sensor materials are very hard. Le Orange TC5S heap Up yes Sony Exmor series 1/2.9-inch CMOS, with a total of 2 million pixels, can shoot 1920 * 1080P videos at most.
Its unit pixel size easily kills all mobile phones in service, Now, some of Sony's top sensors of flagship phones, although Similar ISOCELL pixel grid technology and optical anti shake are used, but iPh One 7/7 Plus 12 megapixel sensors Only 1/3 inch, unit pixel only 1.22 μ m, and The 1/2.8 inch IMX298 on Xiaomi 5 is 16 million pixels, and the unit pixel is only 1.12 μ m.
In terms of lens, Le Orange TC5S uses a universal M12 lens interface ultra wide-angle lens with a focal length of 2.1mm, and the actual imaging field of vision has reached 170 degrees diagonal, 130 degrees horizontal wide-angle. Corresponding to the ultra wide angle lens is the LDC real-time distortion correction technology, which can alleviate the wide angle distortion of the central main body of the picture to a certain extent.

In order to ensure the perspective and discrimination at the same time, TC5S's ultra wide angle+1080P scheme is just different from the previous TP1's small perspective high discrimination+rotating platform. If flat Hour Never played Vehicle recorder or fisheye lens , the first time to see this wide-angle At that time, it was very shocking. The perspective was several times larger than that of common mobile phones.
In actual use, the shooting range is less than 10cm in front of the base, and the paper towel and water cup near the machine are accidentally put into the mirror. Find a desk or cabinet to put, even if it is only 10 square meters of small space can be photographed completely.
The LDC real-time distortion correction technology of Le Orange TC5S has obvious correction effect in the perspective, mainly dealing with the image edge. The deformation of the image center is similar to the conventional focus lens of Note5. The more wide-angle vision mainly focuses on the edge. Although the overall fisheye effect is still obvious, the object edge deformation is not obvious. The overall wide-angle effect is excellent, Edge degradation control is also good, of course, this may have something to do with its low pixels.
In terms of infrared night vision, if the power of the infrared lamp is too strong, the effect will be affected by the reflection of nearby objects, while if the power is too small, it will not shine on the other side of the field. Between indoor effect and infrared power, Le Orange TC5S chooses the former obviously. Its infrared distance is 7 meters, which is suitable for mainstream living rooms and rooms. It may be a little difficult to deal with luxury houses with a depth of 10 meters.
In actual effect, although the near objects reflect the infrared more obviously, because their power is not too high, it rarely causes the problem of a white picture. The actual distance is enough to illuminate the wall 9 or 10 meters away, and the performance is in line with expectations.
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 it has its own HDR effect in the daytime and outdoors, and can retain a lot of dark details;
metering: The light metering strategy of Le Orange TC5S is obviously adjusted to see more details. The indoor light measurement is very close to the Note5 test; In strong outdoor light, the metering is lowered to keep the details of the bright part; In weak light, in order to see more dark details, its metering will be as bright as the Samsung S7 edge;
White balance: The overall white balance of Le Orange TC5S is relatively accurate, with a slight yellow green tendency. The white balance under the indoor fluorescent lamp is even closer to the naked eye than Note5's deliberately warm style.

Extremely weak light scene
Weak light imaging and noise control: In addition to tolerance, the outsole sensor has obvious advantages in ISO sensitivity. In the weak light scene at the junction of day and night, the picture quality will not decline too obviously, and the noise control is amazing. It's also very ironic Sting, many thousand yuan machines with tens of millions of pixels, extremely weak light discrimination and Le Orange TC5S can not be separated.
Lecheng TC5S Anba S3LM graphics processing chip, which uses H.265 encoding, has certain advantages in video compression, and can save broadband and storage space. The network speed requirement is smaller than that of similar products, but it is still 1080P resolution after all. The bandwidth requirement will still be about 40-50% higher than that of the 720P product. The network speed consumption during high-definition preview is about 100-120k/s.
Voice interaction and special functions
Le Orange is From the field of security and cameras, it has gradually expanded to the field of artificial intelligence and interaction, and launched voice interactive video parenting robots and baby minders. Le Orange TC5S can be seen as the first product in the field of voice interaction and artificial intelligence feedback cameras . Le Orange The official promotion for Le Orange TC5S is "eloquent" And special voice interaction optimization is added.
In terms of hardware, the machine is equipped with dual array microphones, which can recognize users' voice commands within 1.5 meters. More specifically, Le Orange TC5S has all-weather voice recognition standby capability, and can directly execute corresponding operations at any time by saying "trigger command".
Long distance voice and all-weather standby require microphone arrays and special chips. Even in the mobile phone field, only a few flagship ships have such capabilities. Previously, only specialized home voice assistants such as Amazon Echo and Google Home had these features. The difference is that Google and Amazon both made products into audio, while Le Orange put them on the camera.
Function: Although the scheme used by the product is relatively mature, However, Le Orange is very restrained in its functions (in order to simplify interaction as much as possible?). Only voice weather query and video message are the key functions added to Le Orange TC5S. The video message will send 15 pictures and sounds after the voice prompt to the mobile phone client. This sounds a bit regrettable, but the official has obviously chosen to focus on ensuring the availability of the two high-frequency functions, weather query and voice message, which greatly reduces the threshold of use. The elderly and children can operate without learning, and even can be regarded as a special version of "WeChat" without additional operation and maintenance, Just leave the machine at home and you can use it.
Trigger command: weather The trigger instruction of is "today's weather, tomorrow's weather", and the video message instruction is "I want to leave a message", which is very simple and rude. No matter how long the speech is, it can be triggered as long as the trigger command is included. In terms of accidental touch, because these two four words are rarely used near the machine in normal life, the machine has not been touched by mistake for more than a week on the desktop.
Identify distance and environmental adaptability: Measured in the not too quiet In normal office environment, the machine can still hear and recognize commands of normal volume when it is 2 meters away, and the standard of Mandarin is not high. The machine can recognize commands as long as it doesn't speak too fast. It is the product with the lowest requirements for speech recognition distance and volume, which is really a bit dark 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", while the video message will prompt "leave a message after a beep", which will be automatically sent 15 seconds after completion, and the mobile terminal will immediately receive the relevant push, and click on it to view directly. The availability and practicability of the two functions are very high. If there is a problem, the voice broadcast of the machine has no volume adjustment option and cannot be interrupted during the broadcast.
In addition to voice interaction, Le Orange TC5S images can be shared live on WeChat, microblog and QQ space, if you want to broadcast live on Le Orange's own public account and H5 page, you need to pay. If you want to expose it in the discovery section of the app, you only need to apply, and there is no limit to the duration and number of visitors.
There is also a low-key function improvement. Le Orange TC5S supports human shape detection, and can only retain the recognition of human shape objects. After all, if it is only used in the home environment, it basically needs to check whether someone is moving. In the same environment, this function can greatly reduce the probability of false alarm triggering. The number of invalid notices in the office can be reduced by more than 60%. In the past, the camera often took pictures of cockroaches climbing over the table at midnight and gave an alarm. I won't tell you
summary
Le Orange already has TC TP、 There are few mistakes in the software and hardware of several cameras or product series closely related to the camera, such as baby sitter. Even without voice interaction, the TC5S is also a truly smart camera. The tolerance, weak light performance and video compression rate brought by the big bottom sensor and the Anba chip scheme have been significantly improved. The voice interaction, as the main selling point of TC5S, is highly available in the actual experience. Le Orange has made the functions and use methods very simple and restrained. It is not only the technology behind this, but also the estimated need to overcome a lot of internal pressure.
Back to the product itself, TC5S, at the launch stage of the new product, pushed the price down to 299 yuan, and also brought its own 7-day cloud storage and 8G USB flash drive for a year. Among products of the same level, the cost performance advantage is very obvious, even a bit bullying. As a price, it is still sold in the form of limited seconds every day
