MaxIcon 0 Posted August 3, 2015 Hiks get noisy in low light pretty easily. A few things to check: - See if all the IR LEDs are on at night. LED burnout is pretty common on a lot of cams, and when one goes, it usually causes more to go dark due to the design. - See if smart IR is enabled. I never could get it to do anything, but on my Dahua, it changes the IR intensity. If it's enabled, try disabling it. - See if the exposure limit has changed. Hiks do best at 1/30 sec or slower, but get motion blur below 1/30, so that's the sweet spot; 1/60 starts getting noisier. - Make sure the sharpening isn't turned up. Sharpening can increase low light noise pretty dramatically. I think 50 is the default. If you use profiles, make sure it's the night profile you're checking.

Generally Hikvision warranty is pretty straight forward for a replacement camera if indeed the IR is starting to go out. Share this post Link to post Share on other sites
mobileman 0 Posted August 6, 2015 yes run a reset and still seems as if noise on picture sort of looks as if its moving / crawling even though nothing on lens only happening when full IR is needed say between 12:30am -4:am think its send back to china job Share this post Link to post Share on other sites
sh500 0 Posted August 10, 2015 I have the exact same issue. I have 6 of these cameras. Night vision was pretty decent on all of them. Now one of them has a lot of noise on it. Just like the OP, the image was fine for about 8 months. Share this post Link to post Share on other sites
MaxIcon 0 Posted August 10, 2015 If you can post an image of the noise, it makes it easier to see what's going on. Share this post Link to post Share on other sites
