shawn posted:Part of my living is video related. I laugh when I see people stricky use the frame rate as a reference to quality. The overall image is really a factor of three things.
The processor power to encode the video. The compression within the video format. ( Number of I,P frame pictures producing the image. This can vary depending on the camera. So, A camera with plenty of CPU horsepower set to use no compression in which all P frames are displayed will ultimately have a better picture quality at a given frame rate. But, like everything else in life - the computer decoding horsepower is also a factor. You might be surprise how many new base computers with minimal capabilities would have issues with 30fps image at 1080p
with low compression. The computer itself creates lag in the video. So, sort of a crap shoot. When minimal specs are supplied. Yes, the network is another issue!
Most of the 4K stuff today with high resolution and fps requires the use of decoding via the video card. Where the h264 or h265 is offloaded to the video card. Especially the case when many hi resolution images need to be displayed
The cam quality of this cam is like the Lionel caboose cam. A matter of fact. That cam is probably a stripped down version.
i absolutely agree, I would love mjpeg video at 30fps! But, really how much will I use this thing? I need to connect via Microsoft vlc to see what that actual stream looks like. If I can determine the stream profile within vlc!
Hey Shawn,
I didn't mean to diminish the camera in any way. All I way saying is that in 2019, a 2MP camera that can't stream @ 30 FPS has got to be doing so for low processing power purposes.
I work in CCTV Distribution, trust me when I tell you I can sell you a cheap Chinese IP camera that can do 2MP @ 30FPS and I mean cheap. Don't believe me, try searching HIK China 2MP camera on eBay.
In terms of use, I don't have a large layout but I use my setup everyday. I like to see that FPV when I use the trains. I guess its just my personal preference.
I see the lag IP cameras have everyday, it's literally what I do for a living. Some better cameras handle the load better than others, it's all in how few frames can be sent after the P with as few changes as possible. That compression takes power not only to decode but to encode as well so you are correct a good PC will help some of the process.
Thanks for the update!
