Wireless security cameras don't necessarily require the internet. Rather, there are a number of security cameras that can record their footage locally onto micro-SD cards or hard drives so it can be viewed later.
Do you have to have Internet for a security camera?
Even though a connection to the Internet is not required in order to use your IP security camera, it can be a good idea to connect your cameras to the Internet in order to get the most out of your IP cameras. Without an Internet connection, you can only access your security cameras through your local area network.
How do I connect my camera without WIFI?
A: To install a wireless security camera without the internet, you simply place it on a flat surface or mount it to a ceiling or wall. You may also need to place a hard drive somewhere, which may connect to the camera via a cable unless it's wire-free.
