Noise in Nighttime Hikvision DS-2CD2032-I 3MP

[old]

Firmware 5.0.2 (build 130805.) Anyone have any suggestions? It's weird, it used to work fine, but I must have changed something, or maybe it happened when I re-aimed the camera to point further out, away from the house, and down, to capture more of the ground in front of it. Any help / advice is greatly appreciated.






I used Network Camera Critic's settings from his blog, here: http://www.networkcameracritic.com/Hikvision/Hikvision DS-2CD2032-I display settings.jpg

you got a 'before' shot?

@old lower the wdr to less than 10

I went back to day and set it to 5; I'll have to return sometime after it has a chance to record at night, and see how that new setting changes the night time image.

Ah, good question. Here's that before shot:

Okay; I'm getting loads of reflection off the house here, and the scene is underexposed to compensate for the bright, bright reflection off the siding.

Okay, I got another image (below) with the WDR turned way down. It's still full of noise. Anyone have any ideas?
EDIT: I'm not sure why the Noise Reduction Level is now at 48 instead of 100. I didn't change that, and I swear I turned the WDL to 5, not zero, but here's a screenshot of the settings used when the video / screenshot was taken.

That is the nature of these cameras, you need more lighting. You can try increasing the noise reduction and lowering the gain a bit.

Pretty old firmware that you're using...Although I'm really not sure if the newer firmwares would have any improvement with noise reduction algorithms.

Actually, I believe there was slight bump in IQ in newer firmware (at least on my indoor 2432s I noticed improvement), but still it's not going to be enough to make this view better. Noisy 3MP sensor combined with small and weak IRs which actually degrade over time. Either get external IR or add more light.

Argh, I should have done more research, and I would have found "klasipca's" Longse S500 / Hisilicon Hi3516A instead of buying these 3MP Hik Bullets! Oh well, next time. (Well, maybe it wouldn't work with my Synology box anyway. Or the ONVIF drivers wouldn't work well with it.)

Yeah, I tried Longse with my QNAP box and I couldn't really get it to work, although I didn't try hard enough because I have Hikvision NVR that does the work.
