    3D noise reduction should always be off

    I think 3DNR should always be turned off. It uses information from previous frames to reduce noise in the current frame. This results in great images of still objects, but hurts the clarity of objects in motion when the 3DNR ramps up. In a noisy image, we can still ignore the noise and make out...

    Learning from IPC-T54IR-ZE purchase mistake

    This is just a funny story I wanted to share. I have a long collection of Dahua cameras spanning almost 10 years. Recently I bought a IPC-T54IR-ZE and set it up to replace a T5442-ZE which itself was moved to replace an even older 1/2.8" camera in a different spot. Now that I could directly...

    Going beyond Dahua and Hikvision for vehicles on residential streets at night. $1000 to $10,000 range?

    Hi, I've been in this hobby for over a decade now, and I'm at a stage where law enforcement regularly contact me for video footage. I run 1/1.8" low-MP Dahua cams in all the prime crime areas with multiple angles, B/W + Color, manual gain, shutter, and minimal 3D NR, to get the best possible...

    screwed up my installation a little

    I think this positioning is good all things considered. You'll get enough advanced warning if you set up motion sensing on the outer skirt of your driveway and there's a good chance an intruder will be approaching the camera dead-on which reduces blur and aids identification (capturing people...

    screwed up my installation a little

    Since the area of interest is still being lit by IR the issue seems to be that the camera under-exposes the area of interest since the IR flair around the edge is bringing up the average brightness of the scene. I have been meaning to test something in this scenario. If you set the shutter as...

    1 TB per day with 8 cams...... WTF

    Check if it's encoding in CBR Check if it's encoding in VBR with too higher gain or sharpness at night causing grain which caps out the bitrate Check if it's triggering excessively and set to save hi-res alert images upon trigger Check if substreams are configured in BlueIris and if they are...

    Review: Dahua SD5A425XA-HNR 4MP 25x Starlight IR PTZ

    Do you get any complaints from people about running this PTZ on a residential property? I am considering one to supplement my very subtle 5442 turrets but I feel the size and overtness makes the PTZ almost a political statement.
