Affirmative, cameras communicate with other electronic machines, like DVR/NVR, using IP addresses. The recorder allocates an IP address to the camera if you use an NVR. However, if you were to utilize a static IP, then your security camera would need to be manually assigned one.
You must remember that an NVR utilizes DHCP (a different protocol) to allocate dynamic IP addresses. To use a static IP address on the inside, you must change the recorder’s configurations.
