Thank you for your support, this keeps us going.You have made an excellent choice. DS920+ is their latest multimedia friendly NAS model. Thanks to a dual LAN you can indeed use one of the bays for a dedicated Surveillance solution. You will be allowed to create a separate RAID (Basic mode with single drive) and with a separate LAN connection, your main RAID/Volume will not suffer from a slowdown. If you merged all drives together then surveillance constant writing would keep those drives bussy.You may need 1TB storage space for recording 30days of surveillance in 1080p 15fps. You can play with a calculator here: https://www.synology.com/en-uk/support/nvr_selector?cameraNumber=1&storeDays=30&perdayhour=24&hdmi=0&codec=H.264&resolution=1920&fps=15&mbps=3.25Better resolutions will mean more storage space required.DS920+ is a future proof model with an option to increase RAM and add an expansion box. It is also not limited - you can install any app from their package list.I hope this helps.
