    PTZ5A4M-25X vs PTZ4M-25X

    Finally replaced older PTZ4M-25X 4MP (less than ideal 1/2.8 sensor) with a PTZ5A4M-25X 4MP (on 1/1.8 sensor). Now I can supply a more direct comparison between the smaller sensor vs larger sensor PTZ's. Both are 4MP images, but the sensor difference is obvious. First is the 1/2.8 sensored...

    Cascades Sunrise on Color 4K-T

    Super nice sunrise over Cascades this morning. Start of video was almost black to the naked eye looking out window, but really shows up well on Color 4K-T

    Delivery Driver with pulsing IR

    Haven't seen this yet. Maybe active LIDAR self driving sensors?

    Blue Heron Eats a Bass

    Great capture. Totally agree, 24/7 recording (in addition to motion triggered recording) has been truly worthwhile for me as well. Motion triggers miss a lot of interesting stuff. Course that means I'm recording nearly 3 TB / day on the RAID.

    Mr. Bear on Thermal and Visual

    First black bear video of this year. Easy to spot on Dahua DH-TPC-BF5421 thermal, but in daytime he also shows up on IPC-T54IR-ZEB-S3. Action is 100 yards out from cameras. Although he usually seems a slow lumbering beast, Mr. Bear is way faster than I can run. Would not want him after me!

    4K-X 6mm uneven focus

    This morning the Color 4K-X 6mm caught crescent moon rising. Earthlight lit up dark portion of moon enough to be visible on 4K-TX sensor. The entire frame is supplied so one can see 6 mm focus is pretty good for distance and onward to infinity. I agree it would not be good for close objects.

    4K-X 6mm uneven focus

    Sometimes it takes three cams to get everything you want in one direction.... One for license plates, one for general street view, Color 4K-X for tight sky view.

    IR halo ring issue in a IPC-B52IR-Z12E S2.

    Anything within three feet and in forward of camera front plane can bounce back enough IR to create a halo. I've been unpleasantly surprised a few times by nearby objects that I thought would be far enough lateral, but proven to be an issue. Solution was moving camera forward or removing...

    Eagle Nebula on Color 4K-X

    It is right at the limit of what the sensor and 6 mm lens can pick up, but the Eagle Nebula shows up as a faint blob in this time lapse. You can see the sensor gain is nearly too high by the presence of fixed hot pixels, but the nebula is obviously a real part of the moving star field. I zoomed...

    4K-X 6mm uneven focus

    Ironically, I'd love to have a 10 mm lens for even tighter framing on one of mine.
