8 Channel/Camera Business or home security system

New, 8 channel and camera NVR business and home security system. 650GB NVR (network video recorder same as a DVR basically only cat-5 x-mitted) included (normally HD is not included with the system and has to be purchased separately at a higher cost than your normal CPU hard drive would as it requires better quality to properly run the NVR) System is brand new never used and the 2021 IPU system from Backstreet Security and retails for $3600 new and uninstalled and $7300 installed through the Backstreet Security website as they are a high End excellent quality System provider. Purchasing this second owner from me you still get the priceless benefit of lifetime phone support and troubleshooting as well as 5 years of a manufacturer full warranty that provides full set up support as well as the lifetime system updates and support. Will Consider a trade for an electric bicycle or ECU or scooter of equal retail or close as well. My business failed during pandemic and never installed these.
