With the advancement in technology, there are several camera connection methods with one of the most common being the USB. In recent times, the essence of the USB has been seen diversely. Hence the reason why we will be breaking it down for you in this post, discussing everything you need to know.
USB, which stands for Universal Serial Bus, was first introduced in 1996 by a few American companies, including Intel Corporation, IBM, and Microsoft Corporation. It’s meant to serve as a simpler method of connecting hardware to PCs. Before this invention, a PC normally had one or two serial ports, mouse & keyboard ports, a parallel port, and probably a joystick port.
A USB port served as a standardized method to connect a variety of devices while providing significant advantages in speed over other connection methods.
At first, the adoption of USB technology was slow. This was a result of the fact that computer manufacturers were slow to integrate USB ports into their machines. Peripherals manufacturers, on the other hand, were also slow to introduce USB products to the market. To make matters worse, when the technology was first released, operating systems only offered a limited amount of support.
However, the story changed in 1998, after the first generation of Apple Inc.’s iMac was introduced into the market. This action by Apple effectively forced other manufacturers to follow the standard. Since then, several devices, including cameras, webcams, printers, scanners, and keyboards make use of USB.
This is a camera that functions by plugging it to a computer through a USB cable. The feeds from the camera are transferred to the computer where a software application allows you to view the pictures and also transfer them to the internet.
The software you use can be set to show images on a time interval using the FTP (File Transfer Protocol). And it can also be set to provide a live feed.
When FTP is used, the images are static and are updated on a regular basis at intervals of one minute, one hour, or even longer. Well, they are very simple to set up, but the image delay makes them far less interesting to watch than a live show.
Nowadays, USB ports are built in numerous devices, hence the application of USB cables. Ranging from webcams, TV receivers & video recorders, digital camcorders, and personal computers, USB cables are used for connection purposes.
USB cables are used in the recording and sending of video feeds to TVs, websites, and other platforms for live stream and playbacks.
Just like cameras, digital camcorders are used to record and send videos through the use of USB cables.
All PCs produced nowadays are built to have ports to support the USB cables used in doing several purposes, such as sending and receiving files.
USB cameras are used for several purposes in numerous institutions,especially used for video conference. Below are a few of the scenarios where they are mostly applied.
Location barrier is one of the reasons why people are not physically present for esports and sports activities. Sports and events need visual coverage for record matches and the convenience of people at home. Sports commentators use USB webcams to connect their commentary and the sports & esports match process, which provides the best experience and feeling to sports lovers and game lovers.
When it comes to Online International Summit or national summit, the USB conference cameras provide premium audio-visual solutions wherever council members are, they can easily join meetings and partake in decision-making. Journalists and newsmen could also be easy to connect with people for news and interviews, no matter where they are. Our USB webcams and USB PTZ cameras enable more effective collaboration and communication than ever before.
Trial sessions and court orders are more regulated and fair when they are being recorded as every injustice is traceable. As a matter of fact, the USB camera allows you to document the proceedings of the trial and be useful when you need to have a meeting with an unavailable witness.
Discussed below are the different types of USB ports used in connecting cameras.
Another name for the USB 2.0 version is hi-speed USB. It was introduced in October 2000 as an updated version to the earlier USB (1.1), hence providing improved functionalities with better speed. It’s used to connect several peripheral devices, like keyboards, printers, scanners, mouse, external hard drives, network adapters, mobile devices, digital cameras, etc.
USB 2.0 has various features, such as plug-and-play integration and the capability of transferring files between devices with less protocol. Its advent led to less specialized cable production and lower volumes of electronic waste, as well as offering better convenience and flexibility to users. It can go as far as delivering a transfer speed of 480 Megabits per second. However, it’s less efficient at power management.
Another name for the USB 3.0 is SuperSpeed USB. It was first introduced in November 2009 as an updated version to USB 2.0. Providing faster speed, USB 3.0 supports the data transfer rate of 5Gbps. Unlike USB 2.0 that could only handle traffic in one direction, this version has a dual-bus architecture, allowing the bus to read and write at once.
Also it has improved features like decreased power consumption, backward compatibility with USB 2.0, better power management structure, etc.
In addition to the several advantages provided by the USB 3.0, the cables are slightly thick, which guarantees their durability. However, it’s quite expensive.
Also known as SuperSpeed+, USB 3.1 was first introduced in 2013. Its performance capability is twice that of USB 3.0 and can transfer data at the rate of 10Gbps. Also, it’s backward compatible with USB 2.0 and USB 3.0.
It’s arguably the most common USB, providing numerous benefits, such as increased speed, flexibility, portability, and so many more.
The USB 3.2 is very similar to the earlier version (USB 3.1). The only difference is that it has a total capacity of transferring data at the rate of 20Gbps. Meanwhile, this is made up of two 10Gbps lanes working together.
Here are a few of the numerous features and advantages of USB webcams.
These webcams are always accompanied with a stand or hooks for putting them on a flat surface, shelf, monitor, or other places. They feature high-quality lenses that allow you to get crisp and clear images.
Similar to built-in webcams, USB webcams come with application programs that let you choose which directory to save videos and still images. You can also choose from a variety of color, sound, focus, and other settings.
USB webcams are less likely to overheat as they have larger casings, allowing heat to disperse quickly. They are portable and you can remove one from a computer and connect it to another computer either laptops or desktops.
To increase the distance of your USB webcam to your computer and provide a wider field of view, you can attach it to a USB hub. This is perfect when you want to capture the whole space during a meeting or other events. You can also use it when you need to record a large group of people during a video conference.
The price is low and it’s now the standard configuration. Users don’t need to have much expertise to install it; the technical threshold is low. It can be quickly installed without a dedicated driver.
USB webcams are compatible with several platforms, including Mac, Linux, Windows, as well as some gaming systems like the Sony PlayStation.
This is an in-built function that allows the camera to automatically move between a series of preset positions. The movement can be paused at each preset for some time. The tour will continue until manually stopped or altered by another controller.
Below are the disadvantages of USB webcams.
A shortcoming of USB webcams is sensitivity to light reflection. While some other professional cameras are capable of controlling reflection, USB webcams are not very suitable in environments with imbalance lighting.
Due to the length of the USB cable, this webcam cannot be used for a long distance. Generally, the cable is only 10 meters long. But this can be extended by using a USB hub
Now setting up a USB camera on computers becomes an easy thing. Depending on the type of camera either webcam or PTZ, all you have to do is to follow the steps that will be discussed below.
It’s either the USB cable is attached to your webcam or it comes with a separate USB cable. To start with, plug the USB cable into the USB port on your computer. For laptops, the USB port will be located by the side of your system, but for desktops, it will be at the back and/or front of the CPU.
Using the USB that came with the PTZ or a compatible USB, connect your personal computer with the PTZ camera.
Once your USB camera is connected, open the PTZ Joy controller. Then, click on the CAM 1 icon, and click Set. By now, you should have control of your USB PTZ camera through the Virtual Joystick on the Main Panel.
There are different ways USB cameras can be installed. The choice of the best option depends largely on the purpose, such as the field of view, zoom in, etc.
Below are the most common ways to install your USB camera.
With this, the USB camera is mounted on the wall with the use of hooks and a stand. By doing this, the camera is held in place while performing its function optimally.
This is regarded as one of the best methods of connecting a USB camera as it is fixed to the ceiling and controlled to cover a wide area. With this, your camera can be operated to conveniently cover the whole room.
The USB PTZ camera can be mounted on a tripod stand to control image height and angle. With this and PTZ controller, you can navigate your usb camera remotely with no hassle.
Controlling USB cameras is made possible with the help of some devices and software that are discussed below.
This is an important tool that’s not just used to control the USB camera, but also to set it up. It features shortcuts for easy navigation but it’s plagued with short distance coverage. It can’t function properly over a long distance.
This is a remote control keyboard that allows you to operate your camera’s features and functions with the press of a button. It’s ideal for live streaming and it makes controlling many camera’s functions easy.
There are specifically built USB camera control software programs like OBS, Livestream Studio, Wirecast, vMix, mimoLive or Tricaster that are designed to control the functionality of USB cameras from a separate computer. With this, every control can be made with the press of a few buttons. iOS/Android Control App and OBS plugin could also control USB cameras.
Another way you can control your USB camera is with the use of hardware controllers, such as mouse, keyboards, serial joystick, etc. With these, you can navigate and monitor the movement of your camera.
USB and HDMI are the two most common major terms in audio and video connections. Without a solid understanding of their functions, they can be confusing. To make proper justification to the USB vs. HDMI confusion, we’ve highlighted below the differences between these two connection cables.
This is a premium USB 3.0 video conference camera that delivers 4K ultra-clear images to provide an immersive conference experience. It’s very versatile, working with several conferencing software, totally plug and play, and user-friendly.
This is an all-in-one unit that integrates a standard camera, microphone, and speaker for a superb face-to-face video conferencing experience. It has a 120-degree field of view that captures all participants in the room in high definition. Thanks to the audio algorithm, every word spoken will be heard clearly.
Regardless of what you need the camera for, these are the most important things to consider when choosing.
Check for the possible ways the USB camera can be mounted and compare if it will suit your needs. While the USB PTZ camera might be suitable for wall, and ceiling mounts, what you need might be a USB camera that can be set on a tripod or desk.
There are two types of lens – plastic and glass. The glass lens is more expensive but produces a much greater quality of images. Also, the bigger the lens, the better the image quality.
The lens is a determinant of how much light gets to the sensor. The more the light hitting the sensor, the clearer images will be in low lighting.
If you get hacked and your camera is connected through USB non-hardware connection, it can be switched on to see you. Regardless of what your camera is meant for, ensure that it has a lid and covers the built-in lens on your computer.
The best way to deal with potential lighting issues is to choose a USB camera that has autofocus and low-light correction. If the room doesn’t get enough light and you would rather not put together a bunch of lamps, it’s advisable to invest in a USB camera that can deal with that through internal configurations.
This is dependent on what you are using your camera for. A camera’s field of view is what the camera can see. The larger the FOV, the more area that will be captured. There are several of them, ranging from 60-degrees, 78-degrees, 90-degrees, 120-degrees, etc.
Well, connecting a camera to a compatible USB port will work, but the performance could be compromised. USB chipsets are as well subject to differences that can affect performance. This can in turn manifest as a delay to camera response or reduced speeds or dropped frames.
