Internal memory
On most digital devices, memory is split in two, namely the so-called internal core memory and the external memory. Internal memory is the storage space provided by the device itself. In general, it allows you to store a minimum amount of data except for the latest smartphones that offer a high storage space. In these cases, no external memory is required and most devices no longer even offer an interface for a memory card. Typical devices spy-cameraThey have internal memory to provide users with the recording time they need to function properly. This ranges from 1 to 8GB.
With regard to spying equipment such as the spy camera pen or the camera watch, an internal memory of 4GB can offer a recording time of 4 hours continuously. This is more than enough for normal use. It should be noted, however, that the resolution of the recorded images affects the memory capacity. In addition, most models on the market offer an extension option. As a result, most spy pens have a micro SD card interface with a capacity ranging from 8 to 64GB.
