How Do CCTV Cameras Work Without Internet?

It's very certain that CCTV cameras can work without Internet and fiber optic patch cables. If you choose the right camera, there is no doubt that you can get remote live streaming at your farm, rural home, off-grid cabin, and other remote areas without Internet connection or electricity. For example, cellular security cameras can let you get remote access, motion detection function, and other smart features.



1. Remote Access Function


If you need to monitor your farm or other properties without fiber optic patch cord, you can use the CCTV cameras to save the video on the NVR/DVR, which can get 24/7 monitoring data. After power on, the security cameras and the NVR will communicate with each other via their own dedicated Internet. Besides, the IP security camera with an SD card can recorded all the motion events to the SD card.


When the fiber patch cable has been cut, NVR will keep functioning perfectly because it always connects with the cameras. Besides, NVR will assign IP addresses to the cameras in the same package, so you can record locally after power on. What is more, NVR will receive the data transmitted from the camera and store the video on the hard disk.

2. Motion Detection Function


Another function of CCTV cameras without Internet is that there will be a local live view. You can follow these step-by-step instructions to connect an IP camera to your monitor, such as a PC or Mac without the Internet.


Make sure your security cameras are in a state of sufficient charge.

Connect the camera to the computer by duplex fiber.

Check out the security camera address on the computer.

Change the IP address of the computer to the same network prefix as the camera.


After following the above steps, your IP cameras have been directly connected to the PC and they are located in the same small LAN. You can view the real-time view of the IP camera on the computer, which can also save the record by using the security camera software. In order to get remote live streaming, motion detection alerts, and other smart functions, traditional wireless and PoE IP security cameras need to be connected to your home Internet by multimode fiber patch cord. It's worth noting that POE / WiFi IP security cameras with SD cards can still record live, so you won't miss any important moments that need to be captured after the network is disconnected. On the other hand, security cameras based on cellular mobile data can operate on 3G / 4G / 5G cellular networks, which ensures the use of remote areas without networks.



3. Security Cameras Don't Need WiFi


Even without WiFi, network connection, fiber optic cable patch cord, or power, the mobile security camera allows you to view your property remotely, which doesn't need to connect the camera to a home router or rely on WiFi signals but runs over a 4G / 3G cellular network by optical fiber patch panel. If you want to watch monitoring records on an electronic device without the termination box for fiber optic cable, the mobile security camera is definitely the best choice.
