Say Goodbye to Unstable Wi-Fi & Frozen Cameras

A dropping internet connection or a frozen surveillance feed is more than an annoyance—it disrupts your workflow and compromises your security. Most standard networking devices degrade in performance over time due to memory leaks and cache buildup. The solution is simple but often forgotten: a daily reboot.

Our inline auto-reboot cable acts as an automated maintenance technician for your critical hardware, completely removing the need for human intervention.

How the Automated Power Cycle Works

Built with an intelligent timing module, this cable briefly cuts power for a few seconds every 24 hours from the moment it is plugged in. This hard reset efficiently clears the device's RAM, drops stale IP connections, and refreshes the bandwidth channel. Whether you are running a high-stakes e-sports gaming rig or a continuous remote work setup, you will experience significantly reduced latency and fewer network dropouts.

Universal Compatibility for Smart Homes & Offices

Designed with industry-standard 5.5mm x 2.1mm DC connectors (Male to Female), this adapter fits seamlessly between your existing power supply and your device. It universally supports wide voltage ranges (5V/9V/12V/15V), making it the perfect upgrade for broadband modems, mesh Wi-Fi nodes, and IP security cameras (including Dahua CCTV systems).
