care to shoot me the command you are using? if it works in os x, it should work in linux, lol.

 

[bug99]

Not that you don't look cool, but why do we see two of you in that shot? the shadow is left and slightly up. First image much more prevalent than the second.

@bug99, thats a glare reflection from the car's reflectors..

ffmpeg -f lavfi -i anullsrc -rtsp_transport tcp -i 'rtsp://username:pass@192.168.42.19:554/cam/realmonitor?channel=12&subtype=2'  \
-tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac  -strict experimental  -f flv rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx

better work in linux, im running it on a Raspberry Pi

turned the onboard IR off, let it roll w/external IR Cannon.. with as sensitive as this thing is I was getting alot of dust/sprites from the onboard IR so this cleans it up very well and will make using tripwire on this camera much more reliable.




the reflector on the car also dont flare up the lens, since this monitors parking I always intended on using external illumination.. Pulling ~18.4W right now so this is a bit more IR than is built in.

I'm really liking the use of external IR and just killing the internal, I shall need to pick up an IR cannon to play with.

Internal IR sucks. Once you turn it off and have enough external light you'll hate anything with internal IR especially if you rely on motion alerts.

I was going to look into getting one of those sealevel boxes but if I can get the software motion detection working well enough I won't worry about it lol.

 

[bug99]

When considering external IR, you have freedom of many factors. How does changing the angle of incidence of the light to the angle of the camera affect things? Obviously the built in case they are coincident angles, so you get a lot more shinny objects. I would think the larger the angle between the two the lower the light value (something like 2x the sine of the angle). Have you played with this before? Is there some discussions on the topic?

 

[nayr]

It helps alot with reflectors to have some distance between camera and light: Retroreflector - Wikipedia now the further away the reflector the further away your light source needs to be.. but if your watching a parking area full of reflectors it can be a very nice improvement.

you dont need much separation to kill out other reflective objects, less than retro-reflectors.. spider webs, rain, snow, dust, fog, insects just vanish and become unseen once again.

you also get depth data on your video, onboard IR it flattens the image.. without any shadows alot of detail like the length of noses and stuff is lost..

oh fuck!

here he is, been trying to catch this fucker but could never get a good ID.. think I finally got it though, fuckin hippie better watch out now..]

I admit I lol'd

this camera does allow both heat map and IVS to be enabled at same time.. thats nice, though I would prefer to have people counting and IVS.

interesting, I wonder how that heat map works? the camera isn't thermal lol.

it shows where the most activity is; its most usefull for retail stores as it lets you know how people are flowing down isles and help you decide where to place products for best results.

I figured it had to be something like that.

 

[morpheus]

I'm seeing about 5.5W idle on my bench, so the heater and IR are off

Thanks for the info.

 

[redfive]

Ordered yesterday from Andy (with paypal ) My camera should be on its way ...

 

[nayr]

Here's some nice screen caps of SmartPSS showing it going against a few non starlight 2MP Dahuas and a 4MP Dahua



eventually I intend on replacing the trailer cam with another Ultra Starlight, as I want a over view of road/foot traffic and ID of anyone in the yard heading for the trailer/gate..

the font door and back yard PTZ's will be replaced with 1/2.8" Starlight PTZ's, starting with the front door next.
