A Complete Guide on What a USB Camera is

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.

History of USB

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.

What is USB Cable Used for

What are the Different Types of USB Connection

Discussed below are the different types of USB ports used in connecting cameras.

USB 2.0

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.

USB 3.0

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.

USB 3.1

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.

USB 3.2

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.

USB webcams are compatible with several platforms, including Mac, Linux, Windows, as well as some gaming systems like the Sony PlayStation.

Automatic Tours

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.

Disadvantages of USB Webcam

Below are the disadvantages of USB webcams.

Reflection Sensitivity

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.

Not Suitable for Long Distance

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

USB vs. HDMI: What are their Differences

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.

  • USB is an acronym for Universal Serial Bus, while HDMI is a short form for High Definition Multimedia Interface.

  • A USB is primarily used to provide a standard connection interface for PCs and consumer electronic devices. An HDMI, on the other hand, provides an interface between audio and video sources.

  • With a USB port, USB devices can be connected with each other and transmit digital data over USB cables. HDMI, on the other hand, supports standard, enhanced, or high definition video, and multi-channel digital audio just on a single cable.

  • A micro USB can be used to charge a camera, mobile phone, or e-reader. It can also be used to transmit data straight to your computer through the USB connection on each gadget. On the other hand, a mini HDMI is used for audio and video purposes only. It cannot be used to charge gadgets or transfer data.

How to Choose a USB Camera

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.

Field of View (FOV)

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.


This simply has to do with the clarity of the image captured. A clear picture is always the best. And it’s important to note that for digital video, resolution and frame rate work together. While most cameras have 1080p resolution, nothing beats 4K. For frame rate, you should choose anything more than 60fps to get the most natural look in a video.

How to Use USB Cables for Longer than Standard Lengths

USB cables have their boundary when it comes to length, making them unusable in certain situations. However, the camera wiring can be increased by using USB extension cables like Telycam extension cable 41, 42, 43, and 45. They can help elongate the range of the USB up to 100 meters.

Why is a Dedicated USB Card Recommended for Each Camera
