At TVT Sri Lanka we deeply believe in quality products. All the cameras we sell including these night vision security cameras record crisp, clear video even in complete darkness. The days of grainy night time video are long gone! We offer a variety of resolutions ranging from 600TVL CCTV Cameras to 4K 12 Megapixel IP cameras. All Infrared Night Vision cameras have Day & Night technology that allows the cameras to switch to black & white mode in low light. There are mainly 3 different types of video signal types, i.e. Analog, HDCVI, and IP. Please be sure to select the signal type compatible with your security recorder.
