    Hi there guys!

    I have a GoPro on the handlebar of my motorcycle and would love to be able to record the screen of my RD when it goes off showing the Band/strength and such. I've already had 4 encounters...3 saves and 1 with a bad outcome (I/O ----- ticket, Park Ranger coming out of a turn pretty much in front of me giving me no time to properly react and reach PSL but at least I was able to slow down a good chunk of mph which translates in no court appearance)

    The problem I'm having is that it "blinks/jumps" like crazy to the point you can't even read what's on the screen at all (only on video, in "real life" I can read it no problem) - I have a SmartRadar so the problem I am experiencing is with the escort tiny remote screen, I think it has LED bulbs? not sure!

    Camera is a GoPro Hero 4 Session... any ideas on how to "fix" this issue? Maybe something in the settings of the camera? Thanks!

    Most likely because the RD uses PWM (Pulse width modulation) to control brightness of the LED display. PWM basically "pulses" the LEDs which make them seem dimmer to the eye. However, if your camera is recording at say 60 FPS, some of those frames are going to get the LEDs in an on state, some in an off state. Try turning the brightness all the way up on the detector, which may disable the PWM.

    I have a Hero 4 Black - to clarify is this an issue with:

    Blinking - screen display / fresh rate / etc

    or

    Jumps - as in vibration from the bike/camera making the screen hard to read in the video

    Or is is a combo of both? I know the new GoPro 6 has built-in image stabilization which looks to be very nice. It is the only feature having me contemplating upgrading right now.

    If you used a V1 with alert logging, it would do that for you.

    It's not from the bike's vibration (even tho this bike vibrates quite some, I believe I did a "good job" making the camera stable)... its like Justin said and makes sense about the pulsating rates. I will try with the highest brightness. I also have noticed that it also depends sometimes on how the sun is positioned, that's why I thought there might be a setting on the camera that I could use. If the sun is not hitting right in front of the lense I am able to read the radar's screen (for example inside my garage) but once I start riding the entire blinking/flickering begins

    The Escort Live has a history log as well... I just wanna be able to record it "live" with my camera
    [doublepost=1515901101,1515624480][/doublepost]tried 60fps and brighest setting and problem persists, eventho it got better like 40%.

    It has to do with the sun/lighting, because inside the garage I can see the RD screen perfectly and as soon as I ride outside and the sun hits, the hole thing starts flickering
