I installed 2 Hikvision cameras about 1.5 months ago and am using them with Synology Surveillance Station (SS). I need to add more cameras, but have concerns based on issues while using SS -especially if I have issues now and will need to $$$ purchase per camera licenses to add more to the existing problems. Does anyone have direct experience with both Synology SS and Blue Iris? What are the pros/cons? Should I highly consider Blue Iris? I have never used or seen Blue Iris -not sure if there is a trial version available. Issues while using Synology SS (I have a Synology DS1812+): :sad2: Higher than desired CPU utilization while there are no other connected users to use various services SS response when using the GUI is too slow. My laptop has crashed many times, only when I have SS running (in IE) while viewing videos. SS settings are used for the video / motion configurations for both Hikvision cameras (in place of using the camera settings): The cameras keep detecting motion almost every few minutes. In those videos there is no movement at all. When reducing the sensitivity it causes the camera motion detection/recordings to go from no change at all to zero detection/recordings. After I starting using the motion mask to exclude areas the recordings now do not show the 5 secs before activity and also several seconds after activity is detected. Example: for my driveway area the recording only shows after everyone has walked out, got into the vehicle and closed all doors. The recording only shows everyone sitting in the vehicle while it's warming up or pulling off. Operation failed message 100% of the time when attempting to delete any video. Thanks for feedback.
