So some specs. I have an older 2016 NVR (Dahua NVR1104-P) 4 channel, etc. etc.

I have the following HD cameras attached via POE (IPLP-SP4IRZ and IPOB-BR5IRZA).

The system was originally purchased from SecurityCameraKing.com 5 years ago by the previous property owner and I acquired it when I bought the property.

I have logged into the NVR using the really crappy native Internet Explorer required NVR access software as well as using EVP on my phone and gDMSS Plus as well. All three can access the NVR, the settings, etc.

Using ALL three I have gone into the remote configuration settings in each of the cameras as well as the settings in the NVR to set defaults there.

In all three I can set "Motion Detection" to ON. It saves and that works. The second option for 'Advanced Configuration' is by default OFF. In all three I have set it to ON and clicked SAVE, it says it is saved, but it will never save as ON. When I exit to the previous menu and go back to the Motion Detection settings, the Advanced Configuration button is set back to OFF.

In the "advanced settings" menu of Motion Detection is the ability to set the Detection Zones/Region for each camera. Two of my cameras face a busy road so I have gone into the region/zone and marked the place the road occupies as exempt from tracking the motion (turned the squares CLEAR from the default RED) and I've saved those settings. 

The ZONE/Region settings DO save to each camera and/or the NVR, however since I cannot save the option to turn ON the Motion Detection "Advanced Settings", I believe the motion detection region settings are not being used or applied. Hence I get hundreds of motion sensor notifications per day triggered by motion in the regions/zones I specifically have marked I don't want motion to be detected. I also believe it is not using the Dither settings, sensitivity settings, etc. which are all also found under the "Advanced Settings" of Motion Control because many times the motion is less than 2 seconds, yet it still registers as a motion event.

1. Has anyone else had issues with either the NVR default Motion Control settings OR the Remote Configuration (each camera's) Motion Detection advanced settings NOT being allowed to be ON? (I set it, click save, it says it saved the settings but when I go back in, it's set to OFF again).

2. Is there something in the settings elsewhere (either in the NVR's really crappy IE locked access and control software) or in EVP or gDMSS plus that needs to be set in order for the Advanced Settings of Motion Detection to be activated?

Any help or assistance is greatly appreciated or if additional information is needed, please let me know.
