  • PPF Test - Getting High Quality Surveillance Video
    ?q=80&t=fit&url=ipvm image%2fba713bb9faf71185749039e139ccaab0dfc48a377ed9eebf8051950eb50bdd1d%2f5bab5c36 4d59 4732 84f5 61dd20c2f559
    Megapixel cameras foster hope for much higher quality surveillance video but how much more and in what conditions? In this report, we answer these questions in depth based on extensive testing. The most aggressive marketing claims suggest a single megapixel camera is equals 95 CCTV cameras. Does that mean you could literally replace 95 CCTV cam...

  • A Major Flaw in Long Lenses and PTZs Found
    ...Theoretically, long lenses should let you capture faces and license plates very far away. For example, over 900 feet away from a 1080p camera one should get over 40ppf from a 100mm lens. But how well does this work in practice? In this test, we took 3 long lens cameras, including: An Axis...
