hi all,

 

case:

actually I've 1024 ip camera and i need a network video recorders to view all cameras , 16 cameras per LCD

it means i need 64 decoders with 1 analog video output or 32 decoders with 2 analog video or 16 decoders with 4 analog video

 

question:

can i use any network video recorder or I've to choose from the same brand of video server ?

also which type you recommend ?

thanks all

You have to do a network load assessment.

 

1. What is your bandwidth per camera?

2. Frame Rate per camera?

3. Bitrate

4. Resolution and compression?

5. How important are these cameras?

 

Yes you can get 64 or 128 per system but why jam 10lbs in a 5lb sack?

 

Distributing your system:

 

1. Reduces per system load

2. Limits # of cameras going down at once. Losing 16 vs 64 at one time can be catastrophic. Certain industries have recommendations such as casinos (4 cameras on an 8 ch server for gaming tables) 16 on general areas. Ask your self how can you live with 64,32, 16 etc going down at once.

3. Reduces machine load. Having your processor chugging at a high percentage creates heat and can cause failure. I don't recommend any machine higher than 40% CPU on normal operation and 60% during playback

4. Less cameras per viewing screen makes it easier to see. 16 vs 32 you get the idea

 

As far as determining the right system for you:

 

1. What matches you cameras manufacturer?

2. What is your budget on machines?

3. What is your budget on licensing? 1024 cameras at $200/ea your $204k into it vs $75/ea at $77k is a big difference.

 

At the end of the day, what you want and what you can afford maybe 2 different things.

thanks so much sir

--------

already i'm using 2 types

 

type #1

 

- LENEL ONGUARD (SERVER)

- LENEL (WORKSTATION)

- LENEL NVR (RECORDER)

- INTERLOGIX (CAMERA)

- LENEL CLIENT USED AS A DECODER BUT IT IT IS EXPENSIVE SOLUTION

 

 

TYPE #2

 

- LENEL ONGUARD (SERVER )

- LENEL (WORKSTATION)

- LENEL NVR (RECORDER)

- PELCO (CAMERA)

- PELCO (DECODER) IT IS LESS EXPENSIVE BUT IT IS STILL HIGH

 

========

MY QUESTIONS NOW ARE:

WHAT IS THE COST EFFECTIVE SOLUTION TO GET AN ANALOG VIDEO FROM 16 IP CAMERA?

 

ALSO IS THERE ANY RELATIONSHIP BETWEEN THE TYPE OF THE DECODER AND THE TYPE OF THE SERVER OR CAMERA?

 

THANKS SO MUCH
