4-Camera 2K PTZ Surveillance Kit

The AOSU C9C-4H kit provides four battery-powered PTZ cameras with 2K resolution and 170° wide-angle lenses for broad outdoor coverage. AI detection distinguishes people from other motion to reduce false alerts. Built-in spotlights enhance night vision while two-way audio allows remote communication. Footage is stored on the included 128GB local storage without recurring fees.

Dual-Band Wi-Fi Network Check

Verify that your router broadcasts both 2.4GHz and 5GHz networks, as the cameras use dual-band Wi-Fi for stable connectivity. Ensure the installation locations receive sufficient wireless signal strength for reliable streaming. Confirm that the mounting surfaces can support the cameras without wiring, since the units are battery-powered and require no cabling.

Sustained Outdoor Operation

Battery-powered operation means recording time depends on motion frequency and spotlight usage rather than continuous wiring. The 128GB local storage will overwrite the oldest clips once capacity is reached during extended monitoring periods. Solar charging accessories can extend uptime, but the kit itself relies on battery reserves for sustained load.

Questions about this item

What comes in the box with the AOSU C9C-4H 4-camera kit and what needs to be purchased separately?

The kit includes four battery-powered PTZ cameras with 170° lenses, spotlights, and built-in 128GB local storage. No separate storage subscription or wiring is required for operation.

Which version of the AOSU C9C-4H should I choose for reliable wireless coverage?

This model supports dual-band 2.4GHz and 5GHz Wi-Fi, so select it when your router broadcasts both frequencies for the most stable connection to all four cameras.

What does the 2K resolution figure mean for daily monitoring with this system?

The 4MP sensor records at 2K resolution, letting you identify faces or licence plates across the 170° view, while AI detection filters out non-human motion to reduce unnecessary alerts.
