CCTV Cameras: image capture devices, often called simply CAM or Cameras. Each camera supports a specific technology; sometimes, more than the most evolved technology they support also the analog one just for testing. Also in this case the technologies are the same than for recorders: Analog Cameras, IP Network Cameras, AHD Cameras, HD-CVI Cameras and TVI Cameras. The differences between CCTV cameras may be the supported technology, the resolution, the technical features, the intended use etc. and they may be remarkable also among aesthetically similar cameras.
