ZoneMinder Forums

Hi all. I am new to Zoneminder, but I see tremendous potential in it. I have a problem concerning signal loss. I can get my camera setup and working pretty good. But then when I try to tweak the parameters "Reference Image Blend" and "AlmRefImageBlendPct" I get signal loss errors. Even if I put the values back to what worked originally, I will continue to get these errors at what I would consider an unacceptable rate, ~ 1 every 45 seconds. Is this a nuance in Zoneminder, or is there something I am doing wrong? Thank you.

Whatever values you use they should be the same for both of those settings.

Thanks for letting me know. I did not know that but, I do by chance have them the same and I still get a signal error. The screen turns periodically blue when viewing through zoneminder. I guess next thing I could try to run an ethernet cord to it and see if it persists?

You are likely getting what some call streaking, This can be caused by a lot of things, There are plenty of recommended fixes but we will need to know what camera you are using and how you have it set up in ZM.

Thank you. I have a Wansview 1080p camera Model Number: NCM625GA-AMUS-GM

Thanks again!

Your values for Max FPS and alarm MAX FPS are invalid. Click the "?", read the help the text, then fix the values.

Ah. I think that might have done it! So far so good. If anything changes I will update this thread. I changed the framerate on the camera to 5 and changed the max fps on alert to 8. Does this make sense? Or should I be doing something else you think?

Analysis FPS and Maximum FPS should be blank except for local (non-network) cameras
Alarm Maximum FPS may be used for network cameras but may cause issues and thus should be blank also...

Oh ok. Thanks! I'm really digging this software!
