Can Milestone Record 24/7 Stream 2 (D1 Or Other Lower Res) And Jump To Max Res On Motion?

Pretty much as the question asks.  Can I set the cameras to record on the 2nd stream which is low res 24/7 and have it jump to the high res 1st stream when motion is detected?  I know i can do it on Openeye, on Salient I can set it to 1FPS on the 1st stream (full resoultion) and jump to 15 on motion.

UD1,

You can jump frame rate using a Milestone rule.  I have not tried changing from low to high resolution.

Yes it's possible to change the recording frame rate after a motion detection event; here is how you would do this with a rule...

Perform an action on Motion Started
from Camera Group 2
Apply setting on 'the device on which event occurred'
settings 'Video stream 1.Resolution: 1920x1080'

Perform action on Motion Stopped
Apply setting on 'the device on which event occurred'
settings 'Video stream 1.Resolution: 1280x720'

 

If you also want to go from recording 1 FPS to 15 FPS, you should have the camera streaming 15 FPS all the time (unless you specifically want to reduce data from camera to server), but choose to record keyframes only. Then augment the above rule like so...

 

Perform an action on Motion Started
from Camera Group 2
set recording frame rate to all frames for MPEG-4/H.264/H.265 on the device on which event occurred
and Apply setting on 'the device on which event occurred'
settings 'Video stream 1.Resolution: 1920x1080'

Perform action on Motion Stopped
restore default recording frame rate of keyframes for MPEG-4/H.264/H.265 immediately

and Apply setting on 'the device on which event occurred'
settings 'Video stream 1.Resolution: 1280x720'

 

 

The ability to make setting changes to an existing stream through a rule can be device dependent so it's worth testing or asking before committing to being able to do this with a specific manufacturer/model. With some cameras, changing the resolution mid-stream can also result in up to a second or two of no video while a new stream is requested which is obviously not ideal.

I believe the original question was whether Milestone can record Stream 1, and then switch to Stream 2 for recording based on a motion detection event. If possible, that could potentially eliminate the gap some cameras might have when switching resolution mid-stream, but currently it's not possible to change which streams are used for live/recording via a rule - only to modify the settings of a stream or to switch between recording keyframes/all frames.

Finally I should note that the ability to change stream settings using the Rules engine is not available in XProtect Professional or XProtect Express. But the "plus" products and XProtect Expert / XProtect Corporate have the Rules engine.

XProtect Express and XProtect Professional are capable of recording keyframes and switching to all frames on event, but changing the resolution based on an event is not possible on these versions.
