The Wireless Camera System NVR with a 12" monitor for the Smonet camera system is constructed from high-quality materials. My set included four cameras and was fairly straightforward to install. However, ensuring consistent operation proved to be a challenge. The system operated without issues for approximately two months, but subsequently began experiencing persistent technical difficulties. Overwhelmed by the frustration of attempting repairs, I ultimately disposed of it at a local recycling center, resulting in a financial loss.
