A couple of questions:

How much space have you allocated to "Alerts" and what happens when that is full ? I didn't see a screen shot for that.
Of the used space on Drives D and the NAS, how much of this is the "Blue Iris" folder and files within?

When I setup Blue Iris, I install Winaero tweaker which allows me to disable windows updates so I never have to deal with the risk that an update causes issues. You can always re-enable the updates if you want to periodically update windows but at least you don't have the risk that a Windows update ...

I have noticed that many cameras I have bought recently come preloaded / configured so a Keyframe is only sent every 4 secs so I guess this is why BI has defaulted to 5 secs. I can see that the majority of casual users would not know to change the Keyframe rate (or know what they should set it to), ...

Update on Ticket ... the 5 sec min pre-trigger record time is mandatory. The bug which may allow some profiles to escape this limit will be fixed in a future version so all profiles will apply the 5 sec min. The response indicated that many users were having problems when using direct to disc if the...

I’ve been using blue iris almost 10 years I think since ver 3.66 and have never experienced an issue with short pretrigger times either. Have been managing a half dozen different installs at some times. However, I’ve only ever used hikvision cameras or same under another brand name.

Apologize if this is a stupid question but I haven’t been able to find an answer …

How do I easily view a hi res alert image full screen in the console or app? Everything I can think of just launches playback of the clip. Maybe this isn’t possible?

Regarding the Ver 5 install, it will automatically pick up all the configuration and settings from your Ver 4 install without affecting the Ver 4 install if I recall correctly. I don't believe I had to manually copy anything over but I did have to go thru and adjust everything afterwards.

I have been using the Panoeagle 8MP Full Color Night Vision Cameras and had no problems. These are a rebranded Hikvision ColorVu camera and are configured in Blue Iris as Hikvision Cameras (be wary that you may need to confirm/change the RTSP port number in the camera setup). The hardware does appea...

You could try increasing the resolution of the sub-stream in the camera video configuration page. Going to a higher resolution sub-stream (but still much lower than the main stream), will still save CPU but might help with your motion detection issue.

It has been quite awhile since I did my version 4 to version 5 upgrade so forgive me if my memory is in error ... I believe the advice was to install version 5 on the version 4 machine, it will create a new install leaving the version 4 in place then you can test and configure version 5 before remov...
