Need some input on system dessign

[Securame 0]

Hello everyone!

 

I have been asked to set up a system that is a little bit of what I usually do, and I would like some input on those more used to high end systems. This system will be replicated (there will be about 8 units), it is for some big institution, and I know the total budget for all systems will be a 6 digit number (Euros).

 

What they need is the following:

 

- System will have 6 video inputs/sources. Source 1 is a VGA switch with 3 computers connected, which they already have, but it can be replaced with another kind of connection (HDMI?). Sources 2 and 3 will be PTZ network megapixel cameras. Sources 4-5-6 are unknown, but they are not supposed to have resolutions that high (one I am quite sure it will be a DVD player).

- Not all those sources will have audio, but some will for sure (1 and DVD)

- All 6 sources need to be recorded real time. The higher the resolution, the better. Sources 1-2-3 will probably need at least 720p, sources 4-5-6 might do OK with D1.

- System will have 3 A/V outputs. Output 1 will be a projector. Output 2 will be a streaming server (so whatever they want can be broadcasted realtime over internet). Output 3 is unknown.

- A matrix switch might be needed; any of the 6 inputs needs to be sent to any of the 3 outputs at any time (different inputs to different outputs).

 

Now, I am thinking all the system in 2 parts. Automated part, which will take care of the recordings, and user controlled part, which will control the PTZ cameras and outputs.

 

First I had thought on doing everything on HDMI, but I don't think there are any HDMI multi channels recorders. I could at least use HDMI on the user controlled part (convert all 6 inputs to HDMI if they are not already HDMI, and use a 8x4 HDMI matrix so any input can be sent to any output).

 

For the recording, I want as much resolution as possible at least on sources 1-2-3. Resolution on source 1 can be changed, so the minimum would be 720p for these 3 sources. 1280x720 resolution on the computers (source 1) and megapixel cameras (sources 2-3). But here I encounter my first problem, I have a VGA signal, which could be a DVI or HDMI signal... but how to record it? Would there be some kind of video server, that could convert me that computer signal into a "virtual" network camera that can be recorded the same way as sources 2-3?

 

Sources 4-5-6 should give less trouble, since they could probably be recorded like an analog camera.

 

So far what I was thinking, and I have chosen HIKVISION because that is the brand I usually work the most with (and know), but I would like ideas on how to implement this another way, or with other brands.

 

I was looking at a Hibrid recorder, DS-9008HFI-SH - http://www.hikvision.com/En/Products_show.asp?id=382

This will allow me to record 3ch IP camera at 720P, and 3 analog sources at D1.

 

I would then have to find a way to convert a VGA signal into an "IP camera" signal, can that be done? Is a video server for that? Any hints on how to record a VGA signal?

 

For the 2 cameras, I was looking at DS-2DF1-672, 1.3 megapixel network speed dome.

http://www.hikvision.com/En/Products_show.asp?id=523

There should be no problem recording these ones on the above recorder, and they do 1280x720 25fps.

 

The other 3 inputs should be trivial; they will either be lower quality sources which can be recorded as analog cameras at D1 25fps.

 

A keyboard will probably also be needed for controling the 2 cameras.

 

Now on the outputs; this Hybrid DVR has 4 outputs: Main (BNC), Spot (BNC), VGA and HDMI. I pretty much doubt this can be used easily for switching what input you want to send to each output, it would be too slow to navigate the DVRs menus to configure the output every time it needs to be changed.

 

Would again a video server work here? I never used one of this, but are this things for connecting to a network stream and output it with BNC/VGA? Or any other appliance I can use, so I can connect one on the projector (VGA 1280x720), another one on the stream server (BNC and D1 should do it), and another one wherever they need the 3rd output... Digital Video Server DS-6401HDI

(Edit: I think DS-6301DI would also tdo the job if I do not need HDMI output - http://www.hikvision.com/En/Products_show.asp?id=69 )

 

This project is just starting and I have barely been thinking about it and researching 2 days, but any inputs will be great, and I appreciate if you have read this far!

 

Thanks!

Hi mind twist. my head hurts after reading all that. but still cant make out what it is you are doing. why are you looking at recording from VGA. are you looking at tapping of a server existing system ??

 

are you going to be using the hikvision dvr to record everything that you have posted?

 

 

you do mention D1 on the dvr. that dvr is not D1 and it will not do D1 at 25fps it will only do 25fps in cif

 

how many cameras are you looking at recording and what are you protecting. ???

Hello,

 

System must record 6 sources and I would like to do it on the HIKVISION; yes. Only 2 of those sources are actually cameras. Source 3 is a VGA switch (which can show signal from 3 different computers, and could be replaced with a DVI or HDMI signal). Sources 4-5-6 will do good with D1 (704x576), I know for sure one is a DVD player.

 

DS-9008HFI-SH can do 8ch at D1 25fps, I am sure of that. It has 8 analog channel which can do 200fps at 4CIF/D1. It then has another 8 IP channels, which could be 8 IP cameras at 4CIF/D1 25fps, or 4 IP cameras at 720p 25fps, or 2 IP cameras at UXGA 25fps (I am interested on the middle option, 4ch at 720p). So I would be using 3 analog at D1 25fps (wasting 5 analog) and 3 IP at 720p 25fps (wasting 1 IP at 720p).

 

System is not really for "protection", it is more for conferences. Everything must be recorded/stored for future use.

 

I think I pretty much got the idea right, I just do not need how I could convert a VGA 1280x720 signal into a stream that can easily be recorded... Converting it to analog and recording it at just 704x576 does not seem such a good idea, text would be too blurry.
