Zhengzhou Danet: can the Internet work without the Internet of things?
Can Internet of things devices work without the Internet? Zhengzhou Danai editor has sorted out some knowledge points from the network, hoping to help you understand the work of the Internet of things!
A common view is that Internet of things devices cannot work without a network. After all, "net" is part of the term "Internet of things". However, there is no simple answer to this question-it depends on the communication requirements of the device.
Internet of things systems are also known as "smart" and "connected". As described in the previous article, their main task is to observe the physical world, gather information about their surroundings, and pass it on to decision makers or trigger actions. To do this, they need a communication channel.
Not all Internet of things devices require a network connection to work properly, but they do need to be connected to other devices on the network to automate certain tasks and allow you to interact with them through direct commands, or customize their configuration. Connecting them to the Internet allows you to control them from outside your local network.
The camera on the local network works perfectly without the Internet, but if you want to access it remotely, you need a network connection to do so.
In many cases, if you want to remotely control a local device, you need to expose it to the network. If no security measures are taken, hackers can directly access and attack them.
Depending on the product, local devices can be accessed through the vendor's cloud infrastructure. This is safer because there are stronger security defenses.
