    Partly cloudy with a chance of Blizzard

    It's a balmy -22F here with a nice strong breeze... Outdoor cameras are all working. Might go snow-shoeing tomorrow if the wind goes down a bit. Time to throw another log on the fire.

    @SouthernYankee, Updated settings as you indicated, will see how works. Didn't do the OS upgrade though, will see how works without. Video looks good so far. Will see how well it triggers. Continuous video seems like a lot of data, but I suppose a 500g hard drive would be ok FIFO should keep a...

    BL Hadware: Intel i7-4790 @ 3.60GHz, 16GB ram. OS- Windoze 8.1 Here's one of the Dahua camera video setup screens:

    So a frame rate of 15 should have Iframe set at 15, where it was? Should I increase the frame rate to 30 and drop Iframe to 30 as well? I have 16 cams on the network. It's a gigabyte network but I might start losing headroom if several cameras happen to trigger at the same time I am thinking...

    Iframe was set to 15 on most of the cameras so I changed to 60. Is there a way to determine the optimum settings for each particular camera other than guessing looking at the video quality during playback? Most of my cameras are Dahuas, but I can't find an Iframe setting in the older Foscam...

    I'll have to look into this Iframe interval. maybe I'll get it working eventually! :) Pre-triggers are set for 2 seconds, maybe I should try 4 and see how it works? Thanks for your insight @fenderman!

    Now I notice my cameras are not triggering/recording properly. Often they will trigger after the movement has left the frame and all I get is a few seconds of audio of a vehicle moving off or footsteps. Not sure if this is due to changing any of the recording settings as done above, seems to...

    Actually all my cameras were set for re-encoding. I suspect this is a default setting. Changing this has eliminated the problem. Many of the other recommended settings have been implemented already such as limiting cameras to 15fps and others in the linked page. Thank you for your help! Very...

    Thank you for the reply. Yes that particular camera had been set for MP4 instead of direct to disk. Here's a video in .bvr format, zipped. This is before changing settings back to "direct to disk".

    pulsing recording quality.

    Noticed over this last week or so the recording quality (when cams are triggered) varies during the recording. Image seems to pulsate between normal quality to extremely low quality pixelated video. This cycles every 2-3 seconds. I did change some audio settings in BI but I didn't notice the...

    Dahua Cam Audio Shootout!

    Amazon. "CCTV Microphone Security Microphone Audio Microphone Tiny Outdoor CCTV Surveillance Microphone" Google should get you close. I notice the same one I ordered is no longer there.

    Dahua Cam Audio Shootout!

    My order came in and I have two microphones now, no real name on them, box says "USA Sales Group Microphone for CCTV security camera", model 008. Connected power and mic to muc plug coming out of camera and I now have audio. Works really well, very sensitive. Just heard a flock of geese go over...

    Dahua Cam Audio Shootout!

    Never tried but wonder how well the cameras trigger with gunshots or such sudden compression sound waves. I have two cameras that trigger with sound (think I have them set up that way I believe) but I don't remember they've ever been triggered by gunshots, even when I am doing target practice...

    Dahua Cam Audio Shootout!

    Grn1z I have one on order. I did message Andy and he doesn't have stock on the mic(s) they carry so cheaper and quicker to order the one on Amazon.com. Tried first to order the one on Amazon.ca but doesn't ship to my location where Amazon.com does... Amazon is just wierd sometimes. Supposed to...

    Dahua Cam Audio Shootout!

    Grn1z I noticed that one on amazon.ca but cheaper through amazon.com. Seems to be a more complex unit than I was looking for, a bare element with solder lugs would be fine. This one also shows 600 ohm impedence instead of most with 2.2k (the one I am using now which doesn't seem to work)...
