    Low-light struggles / improving image quality.

    Personally, I would keep them as they are, but it depends on your situation / goals. If you had a 2.8mm on the alley, and 12mm on the roof, you would have some tighter shots, but still not very tight - E.G you would have 2 'ok' views. I would be inclined to leave it as-is, with the 2.8mm 8MP on...

    Low-light struggles / improving image quality.

    Thats understandable. Some motion would be good to see if possible. You could even walk around yourself if you like. 1/25 is 40ms, I believe, this is a little high. Not sure how precise you can be on the Hikvisions, but try speeding it up a little (smaller number is faster) - you will get a...

    Low-light struggles / improving image quality.

    It is possible using either ONVIF or RTSP - note however, there is less compatibility than Hikvision camera with Hikvision NVR, so adjusting all the camera parameters within the NVR is not possible. Good, but it seems you have skipped the 'Exposure' tab, which may be the most important in this...

    Low-light struggles / improving image quality.

    No problem. I am not currently running BI in this instance, a Hikvision NVR is being used for 24x7 recording. You could start by sharing some sample images from your cameras, your camera models, and settings?

    ONVIF messing with time on EmpireTech IPC.

    OK,, I got fed up and just added the IPC to the NVR with the RTSP streams. Seems to be working OK for now.

    ONVIF messing with time on EmpireTech IPC.

    I have been setting up a B54IR-Z4E from Andy, which has been a great cam. However, I have one issue, not specific to the cam exactly which I cannot seem to solve. I have the cam added to a Hikvision NVR for continuous recording purposes, via ONVIF. This works quite nicely. However, due to some...

    The noise is definitely less after these adjustments, and here are some still captures:

    Low-light struggles / improving image quality.

    Reviewing historic footage, nighttime noise seemed to worsen between the AM and the PM on the 27th. Looking back on this thread, I found I posted this on the 27th: So looks like the lowered shutter (= less light into sensor) could be the cause. For getting good sill images of perps, do we...

    Low-light struggles / improving image quality.

    As usual, thanks all for the information. I have increased NR just a few points, and lowered sharpness to 44 as you suggested. Of course, this is always the goal. When viewing, and pausing to get some stills, I almost wondered if this issue was contributing to stills too. But perhaps not. I...

    Low-light struggles / improving image quality.

    What causes noise, or a kind of 'shimmering' in the video? This definitely was not present to begin with, but I am having an issue with it now. No sure what I changed though? Codec? I know I did reduce 3D and 2D NR a bit, but I thought I did this when I first set everything up, E.G before I...

    Thanks. I have changed to .264H.

    Low-light struggles / improving image quality.

    Yes, I understand. I think currently my cam is set to plain H.264 - I am not sure what benefit H.264H brings?

    Day/Night Switch on Dahua DH-IPC-HDW1530T-S6

    I think it might have actually worked. I modified the shutter, as mentioned, whilst it was still in color / day mode. I know it didn't immediately start using this shutter, as the image was still perfectly bright, even though it was getting a bit dim outside. Later, I checked again, and the...

    Low-light struggles / improving image quality.

    Very nice. You have a better angle of the street itself (of course the main purpose of my cam is people entering my driveway, but it's nice to capture them walking past too), and are possibly getting slightly better face captures. What is the best way to know if you are 'running out' of bitrate...

    EmpireTech web interface questions.

    Fear not - they are fully isolated, VLAN in use, decent firewall, no external port forwarding or other similar horrors!

    EmpireTech web interface questions.

    Annoyingly, I have just found that enabling HTTPS eventually breaks ONVIF access from my Hikvision NVR, which otherwise works very well. I have tried changing the ONVIF port to 443 in the Hikvision NVR, but this didn't help. So in an effort to get the camera back online, I had to disable HTTPS...

    Low-light struggles / improving image quality.

    The distance is about 60ft to those targets, plus a bit to account for the height of the camera (2nd floor soffit). So not too bad considering camera position. Mainly the onboard IR. The only additional light at in that example would be: IR from a small overview turret, but this is over 80ft...
