ip system streaming

[batortherottie 0]

Hi there new to the fourm!

 

We have a 15 camera dvr system currently. The cameras are stretching over a 1 km distance. The main system is at the opposite end of the site that we monitor it from. They are also monitored from 2000km away for 8-12 hours of the day. We would like to change our system and start getting rid of our pelco 480 lines of res cameras and start adding some ip cameras in untill the pelcos are gone. #1 - is there a way we can use some of the rg6 cable from existing cameras without loosing picture quality (would like to start with some 1.3 -2 meapixel cameras because we need 25 to 30 fps. and better picture quality). #2 - We will be moving the main system to the same end of the monitoring site sometime, but they still need to be monitored from 2000km away and the whole point of changing systems is to improve camera quality and being able to zoom in clearly. Would we have to sacrifice quality when streaming or is the software that would let us go analog or something else 2000km away as they don't use play back or any other features. They just watch. Streaming 15 ip megapixel cameras would just kill us for 8 to 12 hours a day.

 

I hope I got this right about streaming ip cameras.

 

Thanks for any help.

There are several options for this - check some of these:

BTW, do you really NEED 25-30fps? In many cases, you won't even know the difference at 10-15fps. See some examples here: http://www.panasonic.com/business/security/demos/PSS-recording-rates.html

You would almost certainly need to reduce the bandwidth for this, either using lower resolution, lower framerate, higher compression, or some combination thereof. I take it this is being done over a standard internet connection of some type? Cable or DSL? Do you know what the upstream rates are for the site with the DVR?

 

One benefit of IP cameras is that your remote viewing site could connect to individual cameras directly... if you're using dual-stream cameras, you could view a low-bandwidth stream remotely while recording the high-quality streams locally.

Thanks for the info,

 

The wiring options should work fine. We are monitoring a piece of infrstructure and need to have smooth video for majour incidents or problems so max fps is very helpfull, but you can't have everything . I know 20-30 fps is really close but 15 starts to get a little choppy I thought.

 

In the matter of the internet speed we have I know its expensive compared to home like $300 a month can't remember speeds. I havent really concerned myself about it right now as we are getting ready to run fiber to change location of our main dvr system. Its going to be expensive.

 

Right now the people monitoring just log into our system and watch. I would like to make it simple. Sometimes I think logging in is already hard enough for them to accomplish,lol. They need to see all the cameras on one screen.

 

Right now we use Vicon and they are very expensive and propriatry, so we can only do so much on our own without them, if something goes wrong with it we send it to Toronto. Plus we have two systems one sitting there just incase the other one packs it in.

 

Thanks
