Liquid crystal display "C2422HE" equipped with IR camera, microphone, speaker, etc.
Supports face recognition function that can easily perform various authentication tasks
Dell Technologies also has three models of LCD displays equipped with IR cameras, high-performance microphones, and speakers. Among them, the C2422HE has the smallest LCD size and the lowest price.
The standard price of the direct sales site is 73,481 yen, and currently it is discounted by 16,000 yen to 57,481 yen. By applying the "Telework Camera Speaker 20% OFF Coupon" to this price, you can purchase it for a whopping 45,984 yen. It seems that the application of coupons and discounts will continue for a while, but it may end suddenly, so I would like to purchase it as soon as necessary.
The liquid crystal panel uses an IPS panel with wide color reproducibility and a wide viewing angle, and the surface is treated with a non-glossy treatment. Glossy panels tend to reflect external light such as fluorescent lights, which makes your eyes tired easily, so non-glossy panels are more advantageous if you use them for a long time in business. Also, because it is an IPS panel, there is no change in color when viewed from above, below, left or right, and you can check the design and color with the correct color.
There are three video input terminals, DisplayPort, HDMI, and Type-C, which doubles as a power supply and USB connection to a PC, and can be used by connecting to various PCs. In particular, Type-C is a convenient interface when using IR cameras, microphones, and speakers, which will be described later, so if your PC has a Type-C connector that supports video output, you'll want to actively use it.
The IR camera and microphone are mounted on the top of the LCD display. When the package is just unpacked, it is stored inside, but if you push the IR camera part a little, the lock will be released and the part where the IR camera and microphone are incorporated will protrude upward.
An IR camera is a high-performance Web camera that can grasp a three-dimensional structure using an infrared sensor in addition to the image sensor that a general Web camera has. On a PC equipped with an IR camera, the face recognition function can be used by signing in to Windows 10 or logging in to a website.
If you use a password or PIN, you must use the keyboard to enter the specified text. Even when using fingerprint authentication, it is necessary to touch the fingertip registered in the fingerprint authentication sensor. However, with the face recognition function, all you have to do is turn your face to the IR camera. After that, the IR camera and Windows 10 automatically perform authentication work and display the desktop.
I tried using the face recognition function using the IR camera installed in the C2422HE, but like the IR camera installed in other notebook PCs of Dell Technologies, the face recognition process is performed at a very high speed. Will be. For example, it takes a second or two from the lock screen immediately after startup to display the desktop screen after face recognition. Authentication work is done almost instantly, and you can start working immediately.
The image from the camera is smooth, and the performance of the microphone is quite high.
Also, as introduced at the beginning, one of the features is that you can comfortably hold a video conference by installing such an IR camera, high-performance microphone, and speaker. By the way, if you want to use these additional functions, you need to connect C2422HE and your PC via USB. This is because IR cameras and microphones are recognized by PCs as USB-compatible peripherals.
If you use a Type-C cable, it's very easy because you can connect the video output to your PC via USB with this single Type-C cable. If you are connecting your PC to C2422HE via DisplayPort or HDMI, use the included USB cable to connect your PC to C2422HE.
If connected correctly, Windows 10 will automatically install device drivers for IR cameras, microphones, and speakers and make them available. Users do not need to install device drivers or utilities again.
However, in order to use those devices with various video conference tools such as Microsoft Teams and Zoom, it is necessary to specify the video input (camera device) device, microphone, and speaker from the setting screen. It's not a particularly difficult task, but if the camera image is not displayed or there is no sound from the speakers, check these settings.
According to the manual, the number of pixels of the IR camera is 1,920 x 1,080 dots, and the frame rate is up to 30Hz. With average specs for a business webcam, the face during a video conference or call was clearly recognizable and the movement was smooth.
One microphone is installed on each of the left and right ends of this IR camera. It also supports a "noise canceling function" that reduces ambient noise and an "echo canceling" function that cuts echoes and prevents jarring noise from entering, which is also a perfect microphone for video conferences.
In fact, even when talking on the phone, everyday sounds such as the sound of the air conditioner and the sound of the electric fan were almost canceled, and the sound of the keyboard that was intentionally typed to be louder was also significantly reduced. Since you can hear the voice clearly during the conversation, there is no situation where you cannot hear the voice during the video conference or you cannot hear your own voice.
The speaker is a 5W stereo speaker. Since it is thin, the treble and bass are modest, and the midrange is strongly balanced, so you may feel that the music playback and game sound are a little lacking in power.
However, in video conferences and video conferences that mainly focus on human voices, the voices during the conference, including your own voice, can be heard clearly and well. Each of these features is optimized for video conferencing, and I find it very suitable for teleworking.
Another interesting thing is the hardware button on the left side of the speaker. It's a touch sensor, and when you touch the Microsoft Teams logo on the far left, Microsoft Teams launches and opens a window. In addition, you can start / end calls and meetings, adjust the volume, and mute the microphone from this touch button.
Of course, you can operate it from the desktop app, but depending on the situation, it may be difficult to reach the keyboard and mouse. Also, depending on the position of attending the meeting, the microphone may be muted and enabled many times. In such a case, it is easier to touch the button of C2422HE than to operate it with the mouse.
These buttons are also available in communication apps other than Microsoft Teams. For example, in Skype you can start and end calls, volume buttons, and mute buttons. Zoom supports the operation of the volume button and mute button. Even companies that don't use Microsoft Teams as their in-house video conferencing app can take advantage of these useful features.
Great benefits for both desktop and laptop
In addition to these functions, you can connect multiple PCs to the "Dell Display Manager" that allows you to divide the display area of the LCD display and automatically rearrange it, and to easily make detailed settings for the LCD display on Windows 10. Supports KVM function, wired LAN port function, etc. that can be used while switching.
These additional functions have great merits, especially when combined with a desktop PC. When combined with the recently released desktop PC "OptiPlex 3090/7090 Ultra" that can be incorporated into a liquid crystal display stand, you can create a space-saving telework PC that can be used in the same style as a PC with an integrated liquid crystal display.
It can also be fully utilized in combination with a notebook PC. After all, the high-performance IR camera built into the C2422HE and the microphone with noise-canceling and echo-canceling functions are still only installed in expensive notebook PCs.
The speakers of a general notebook PC are basically equipped with "just make a sound", so they are not suitable for video conferences. However, if you add C2422HE, you can make up for these weaknesses all together.
If you create a multi-display environment with the liquid crystal display installed in the notebook PC and C2422HE, you will be able to work using a wider desktop, which is a great advantage in terms of preparing a work environment for teleworking.
In this way, the C2422HE, which supports business from all aspects, can be said to be the perfect LCD display for users who want to prepare a telework environment.
