IP cameras without a subscription are fully usable with no monthly recurring costs. These security cameras store their footage locally. You don't need cloud storage. If you choose a camera without a subscription, you only need to buy a memory card once. In some cases, that's not even necessary because the camera has its own storage space or can be connected to a base station with local storage. Make sure to check the possibilities of a camera in advance, so that you choose a storage method that suits your preferences.
