How much "up" speed should be required to view events remotely?
I have a Dell Blade server set up with CentOS 6.5 and ZM 1.28.1. It is configured for
remote access and I can connect to the ZM page but events cannot be viewed. I can
select "frames" and view each individually and I can export events and download them
but I can't view recorded events or live monitors remotely.

ISP is RoadRunner 1X15.

Thanks!

I have these problems on Internet Explorer. Try chrome or firefox, worked for me. Don't think it's an upstream issue.

A friend is running 9x 1080p cameras with ~1mbit upstream I can see the livestream or recorded events. But it's not extremely fast.

I never use IE. The issue is repeatable with both Chrome and FF. Since upgrading to 1.28.1 the live streams will usually display
eventually and are very choppy. Replay of events never works right. It loads for a while then displays a partial frame then stops.
Buttons (play, pause, rw...) don't work. This seems odd to me because I would think the browser would cache the event display and
reloading the window or rewinding the video would allow it to play from the cache.

I've also been having the same issue with Brighthouse networks Roadrunner. I used to be able to check my camera and now all I get (if I'm lucky) are individual still images and no live feed.

Determining bandwidth requires the camera frame rate, the compression type, and the camera resolution.
What you need to do is go to a third party manufacturer's site and use their bandwidth calculator.
Axis has one here: http://classic.www.axis.com/en/products ... /index.htm

Plug in a generic mjpeg camera, the frame rate, and the resolution. If it asks you for the recording mode or duty cycle, set it to continuous or 100% respectively. It will spit out the estimated bandwidth you need to view one camera remotely.

Note that is the upload bandwidth and NOT the download bandwidth! This is the smaller value for bandwidth that your ISP may not readily come right out and tell you. This is the bottleneck for most asymmetrical broadband connections. If you are approaching ~%70 of your upload bandwidth then your connection is not fast enough.
