Realtime or H264

[ei0675 0]

Just a quick question on which is the better DVR.

 

A 16ch H.264 or a 16CH realtime??

[rory 0]

Neither. There is alot more to a DVR then the both of those.

For example, the DVR's H264 could be terrible quality.

The DVR could only be real time in very low quality.

There are much more specifications you chould consider rather than these two.

However, H.264 is an advanced technology of video compression, Which may save you more HDD space. And it offers you better network transmission quality.

As for Real-time, you should consider it under what format. HD1? Half HD1? CIF? Or something else...HD1 is the best!

 

Thanks!

 

What do u call HD1 ?

Are u talking about Stand alone DVR ? or ?

HD1??? huh? 720X240? (I think?)

 

I prefer between 4CIF and 16CIF+ or so, myself!

That was my point about "HD1"

confused, HD1= Half D1, Full D1= D1 resolution. You also should concern display mode with D1 or playback mode with D1, palyback mode D1 was Full D1. Almost DVR display can achieve to D1, but playback always CIF(real time).
