CPA has received many calls regarding image quality and what is the difference between various resolutions available on Video Recording devices such as Security Surveillance Systems. Many manufacturers offer these 3 resolutions on their newer DVR (digital Video Recorder) devices. = D1(720×480), HD1(720×240), CIF(360×240) for Analog systems. For the most part the NTSC format is common in Canada and the USA. Europe and other Asian countries uses PAL. In the end… it all depends on the clarity you expect from the recording device, and inevitably the playback as well. The higher the resolution, the more space is required on the recording HDD (Hard Drive Disk) installed in the DVR. A larger HDD will allow the user to record at a higher video quality (D1) and have a better image quality during playback.
Thank you…
