What is a mini CCTV camera? Arbitrarily we can say that a mini CCTV (Closed Circuit TeleVision) camera is any camera that is smaller than the majority of CCTV cameras sold as "Standard" sized cameras. But generally, when the term "mini CCTV camera" is used, reference is made to the small cameras normally used for covert recording.
A spy camera DVR or Digital Video Recorder usually differs from typical digital video security system DVRs because of the necessity for portability. Most spy camera models capture video at a lower size than standard which also requires lest DVR capacity.
