Review on VIKYLIN UltraHD 4K 8MP POE Security IP Camera Bullet OEM DS-2CD2086G2-IU With AI Human Vehicle Detection, 2.8Mm Fixed Lens, Built In Mic, MicroSD Recording (256GB), IP67 Waterproof,131Ft Night Vision by Nate Eich

REVIEW UPDATE 10/10/2020:I must say that Vikylin's customer support is very decent and prompt to respond, considering the hour differential from China. They sent me another custom firmware update, unique to Vikylin cameras, which does install, but it is the same old version that came with the camera. Their firmware follows the same naming convention sequence as Hikvision's so it is obvious this is an older version, which means this camera won't be updated until Vikylin updates their own custom firmware from Hikvision's latest, which may take a while for all I know.So in short, the camera does work as intended, their customer support is prompt and ready to help, and their customer service policies are very much in line with what you would expect from a good U.S. based company. They issued me a full refund without requiring the product returned, for which I am grateful. I am changing my rating to 4 stars, deducting one star only because the firmware is limited to only accept Vikylin's own, which does not seem to stay current with Hikvision's schedule.---------------------------------REVIEW UPDATE 10/7/2020:After spending several days in back-and-forth email communication with Vikylin support, we found out that the firmware in these cameras cannot be updated, not even with the firmware provided by Vikylin. They sent me 4 different versions via email links, since their website does not provide them directly for these cameras. None of them worked. They all failed to update without explanation. The update just aborted, no matter what we tried, following the same exact procedure I followed with other Hikvision OEM cameras from other vendors, all of which update without problems. Vikylin offered to give me a partial refund, for which I have waited 7 days past when they said they would do it. I'm tired of waiting and I just don't want to keep a crippled camera that cannot be updated. Changing rating from 3 to one star. Returning camera back to Vikylin.-----------------------ORIGINAL REVIEW:The camera is pretty decent when it comes to image quality and features. After all, it is a Hikvision. But the seller restricted the firmware to only allow updates from the seller. Unlike all the other OEM cameras I have tested, these prevent you from updating from Hikvision's website. I find this rather inconvenient and almost a deal breaker. If it wasn't for the good price, I would have returned the camera due to the crippled firmware.As far as the night vision and image quality, I find little difference between these and the regular 4k turrets.4mm lens is nice to have. The additional smart detection features (unattended baggage detection, object removal detection, face detection, scene change detection) are only usable if you don't use H.265+ compression, which for me is a more important feature, so I don't use those smart features.
