    Dahua's 2MP Starlight cameras provide daytime image quality roughly 2 to 3 times better (more detailed) than Reolink. I had a Reolink bullet outside once. Hated it.

    My 2MP Starlights are as crisp and clear in the day as my Dahua 6MP and 8MP. All three look great. Use the IPVM Camera Calculator V3 to see the diff in image quality.

    Do your reolinks support VBR? That can lower the bit rate too. My 8MP cam using VBR has a normal bitrate of just over 1000kbps.

    Heed @fenderman, run don't walk to return the Reolinks, and stick with Dahua or Hik or IPCT's own brand of cams.
    All sorts of examples on this board.

    You guys are great. Thank you.

    I have a return request into Reolink and their support is trying to pretend that it’s my settings. I’m pushing them to just complete the return.

    12 Dahua 2MP cameras at $130 each is pricey. Do you know anywhere they sell packs of these?

    For VBR I don’t see it in the Reolink 410-5MP menu. I lowered the Bit Rate to 1024 just now to see what that would do.

    Buy once cry once. $130 per cam isn't pricey in the cam biz.

    What @looney2ns said. Per camera prices for quality reliable cameras from either Dahua or Hikvision are about $120 to $170, depending on features. If you're willing to wait for slower ePacket shipping (23 to 33 days delivery) you may be able to save a bit.

    It's cheaper to do it right the first time than buy Reolink trash and have to replace it a few months down the road. I've been there and done that!

    That sucks they don’t support VBR. VBR lets the bit rate run low when not a lot of activity is happening and then ramps up when there is. Setting yours to a constant 1024 to see the effect in BI is ok, but you can’t leave it there because it’ll degrade image quality when a lot is going on. That’s a big strike against Reolink IMO.

    Hokey smokes, Bullwinkle! I just replaced an older Chinese 4431C-A 4MP with this 2231RP-ZS and the PQ is simply frakking incredible.
    Added two pictures, one with the garage lights lit and another with them turned off.

    Really? That’s good to hear.
    Reolink is still playing games with me on my return of 12 cameras.

    Tell them their H.264 implementation is broken. With no ability to adjust I-frame intervals, and no VBR settings, it is insufficient to meet your requirements.

    Time for either
    1-A charge back to your credit card.
    2-If you are in the US, contact your state's Attorney Generals office.
    3-Put them up for sale on Ebay.

    What is D1 res? Is it 750p? I cant imagine anyone not using NVR + TinyCam or Iris+TinyCam for viewing. Is this a concern?

    Thanks for catching that, that turned out not to be the case... I just updated that post. This camera supports multiple devices connecting to its one 1080P stream at the same time, so using a NVR/Blue Iris + TinyCam at the same time shouldn't be a problem.

    Does Dahua (this model) comes with color night vision?

    Color night vision, with any camera, depends on the light level and sensor sensitivity. I can "force" my 2231 to a color image at night, but there's a street light about 200 feet away in front of it, but out of the field of view.

    Guys - the 2231 mounting size (with or without the mounting bracket) is just way too big for my use.

    I had selected the Reolink bullet cameras because its mount size (B10/B9, 69MM) was an exact replacement for the previous SamsungSV cameras I had.

    Please don't flame me, but is there another camera than the Dahua 2231 that you would recommend that would be more the size of these bullet mounts?

    Anything but Reolink garbage! There are numerous Dahua models, bullets if you must have a small foot print mount, that make Reolink and all the other, similar, brands look like the junk they are. Try a IPC-HFW4231E-S for example. I get usable color video at night with a streetlight about 150 or 200 feet behind the camera.

    Low end junk like Reolink, SV3C and most others, son't send enough key frames, have sub-par sensors and junky optics.
