In all of the 231 private investigations firms, 765 private investigators, and 829 restricted private investigators in British Columbia, you have decided to choose CPA International Investigations Inc. as your go-to team for all of your surveillance, security, and investigative needs! WE THANK YOU ALL!
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(720x480), HD1(720x240), CIF(360x240) 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.
CPA thanks 2MCCTV and author Nydia Perez for posting this clarification for CCTV lenses and how one applies to standard viewing.
