ZOSI’s 32-channel PoE system is built for large-scale surveillance. It starts with 16 high-resolution 8MP cameras and can expand to 32, making it a scalable solution for sprawling properties, multi-building sites, or businesses that need to grow their coverage. The included 4TB hard drive provides substantial local storage, a critical feature for serious security.

Setup is straightforward. Each camera gets power and transmits data over a single Ethernet cable, which ZOSI includes. The plug-and-play design eliminates the need for separate power supplies near each camera. In daily use, the 4K resolution delivers clear, identifiable details, while smart detection for humans and vehicles helps filter out irrelevant motion alerts. The one-way audio lets you listen in on monitored areas, though you cannot speak through the cameras.

The cameras are housed in rugged, IP66-rated metal casings built to withstand harsh weather. Be aware that the audio is strictly inbound listening only, and reaching the full 32-camera capacity requires purchasing an additional compatible PoE switch. For the price, it delivers a comprehensive, professional-grade foundation for a wired security network.
