recording audio and video with security cameras

[irishattorney]

Hi,

Alot of my cameras have the ability to record audio, my card is the 4400 and when I was installing, it looked like it was audio capable. I am running kodicom softare 4.13.

Is my card audio capable? How do you connect the audio? I presently have video connected via cat 5

If not with my card, how can you connect the audio and video?

No idea about how to record audio, but check your local laws. I'm pretty sure that in CA, you cannot record both audio & video without the prior consent of all parties being recorded.

In GA, one party consent is enough.

But anyway, if its your home, just put a sticker on your doors saying this home is private property and is guarded 24/7 with Security A/V monitoring. If they enter, they consented.

IVB, Still use Sagetv? can you get it to work with the security cameras?

Yeah I use SageTV. The way I have it working with CCTV is to have my AverMedia NV5000 output cams 1,2,3 in alternating order on the composite output that it has. I then take that output, feed it into one of the inputs of my PVR500. I setup SageTV to not use guide data, and setup channel 1 for it.

Now by tuning to channel 1, i can see cams 1/2/3 in a 3second rotation. I can view that from any extender or SageClient.

I have SageTV setup that way as well, I just wish there was a way of eliminating the 2-3 second delay

1st off your software is most likely pirated so I won't help much with that, but the solution is rather obvious once you think of it.

I too do this both as they discribe and through a quad processor and now can do preset PTZ functions. I am also working on being able to use it as a network encoder in Sage eliminating the sequence operation and hopefully gaining IP and megapixel support which you can't do like that right now. My Sage server has 2 PVR500s and 4 video expanders totalling 8 CCTV inputs but only 4 possibly encoders or audio passthroughs.

E, you can fix the sequencing by setting up your object detection to send feeds to the TV output. Optionally you can use a motion detector to switch to cameras with PIR motion but you would need an IO setup. (I have this going now too) This is much easier with IO as in either case you are tripping an alarm and you will need to reset it plus if you have the motion connected to a PLC and also the DVRs IO you can do some additional logic before sending anything to the DVR. I have learned quite a few tricks in it's alarms.

Also the 6k series cards have better TV out functions but their bang:buck isn't as good.

Me buying an Ocelot may become a very bad thing.

The delay is caused by SageTV's mpeg2 encoding I believe, don't think it can be disabled for an input (I have the cam hooked up directly to the tuner right now).

I thought you were talking about te delay between cam1>cam2>cam3, if you set it up wrong it can take quite a while to scan through all 32 channels if you are so equipped.

You can reduce the delay in the sage.properties, however you cannot have no delay but you can drop it from the 2500 or 3k ms default. Might not work with all sources though I can see network encoders specifically not always liking that.
