Traditional analogue cameras operate over coax cable. This gives you the ability to cover a far wider viewing area or to get far more detailed pictures in narrow, zoom-in viewing areas.
IP cameras offer resolutions that can range from 1.3 megapixels to 5 megapixels (2560 x 1920) of compressed, encoded transmissions. Analogue camera resolutions range rom 420 to 700 which at the high end can produce sharp images. Generally, digital cameras provide resolutions 6 to 20 times higher than analogue cameras.Īnalogue cameras are limited to resolutions of the NTSC/PAL standard of 720 x 480 pixels (NTSC)/575 (PAL) or 0.4 megapixels (4CIF). If you’re using an analogue camera, you’re not going to recognise the perpetrators face by zooming in. It’s not like what you see on TV cop shows. If you zoom in on the analogue images, you’re going to get a grainier, degraded picture. Analogue cameras have more limited site ranges and don’t offer the zoom-in clarity of IP cameras.

And because they transmit truly digital signals, they offer far greater video detail, which makes them much better for facial recognition or detecting license plate numbers.Īnalogue cameras have overall lower quality than IP cameras, but perform better in low light conditions. They offer more video site ranges, such as a wide or narrow field of view, and better zoom-in capabilities. IP cameras provide overall higher video quality than analogue cameras. Many security camera systems today are hybrid systems incorporating both analogue and digital components. IP cameras are all digital cameras that can send signals over cable to be stored in the network. It sends video over cable to VCRs or DVRs. If you’re considering switching to an IP camera security system, consider these 12 points.Īn analogue camera is a traditional camera used in CCTV systems.
