Hi CCTV has come up in the books a few times. The factor seams to be range and power, for instance Peter was engaged in a magical battle with Varvara CCTV in the immediate is toast but cameras further afield in this case about 2 hundred yards continued to function. Any CCTV recorded before the start of magic use is still accessible as long as the storage is out of range. As to which medium is best for storage after a falcon event. Tape could be eaten because of damage to the recorder but is recoverable, the same with hard disks the actual control modal would be fried but the platters would be fine again recoverable by professionals. Solid state storage is again toast. Again this all relies on strength and range a canny practitioner could kill any local CCTV before engaging in nefarious activities.
