Security camera software
Recently, the quality of the Internet has been improving everywhere. Data transmission channels allow you to record video to external servers on the Internet. This is called storing videos in the cloud.
For home video surveillance, this means that you can do without a registrar at all. However, in this case, you will have to pay monthly the cost of storing your records in the cloud.
This scheme has its pros and cons. The main minus is that if the Internet disappears, then the records also disappear. They simply are not saved anywhere. In case of short-term loss of the Internet, the camera can save recordings to a flash drive. And when the Internet appears again, it transmits the recorded data to the server. But if the Internet disappears for a long time, then there is already a high probability that the records will not be saved.
