FPS-WMV-MPEG4

[omega 0]

Hey Everyone,

 

I'am a newbie and the answers is out there among the threads and there's so much to read....

 

Question 1:

 

A little bit confused, read somewheres that some DVR card w/4 ports, having 'say specifications of 30fps' does that means 30fps is divided among the 4 ports and each port would be getting 7.5fps or does each port will get the max 30fps?

 

Question 2:

 

Which format (WMV, AVI or MPEG4) would give you the best video quality and ease to work with? And what software would you recommend?

 

Question 3:

 

I would like to make my security cams not so visible...

there's one thread I read that recommends, getting a cam with fairly large lens to get the best picture, but it also making the cam stands out like a sore thumb. Can anyone recommend something both IR and regular cam that would be next to a hidden cam without the bulk and providing good results?

 

Hope the above make sense...

Thanks in advance...

1 – depends on the unit and how it is quoted? If it is 30 frames per second for the whole unit then yes divide that number by the number of cameras to figure out your effective frame rate. Some systems allow you to adjust the frame rates for each camera individually so can have more flexibility.

 

2 – The media format question is a little tougher. Generally AVI is just a container for video. That codec that produced the compressed video will determine its quality. WMV and MPEG4 have a wide variety of codecs that determine the quality of them as well. Resolution, bit rate, audio quality all contribute to the quality, files space ratio. There are so may codecs and settings for these codecs that there is not a simple answer to this question.

 

3 – This question I can’t attempt to answer because I don’t have enough information. Picking cameras has got to be the hardest part of any security system. There are so many factors to take into consideration to pick the right camera for the right job.
