Q SERIES FAQ

Frequently Asked Questions

Low-power CCTV cameras and IoT sensors that run on 12V or 5V — network bullets, mini domes, data transmitters, RTU terminals and environmental sensors. Match the model to your device’s voltage: the /12V versions output 9–12.6V, the /5V versions output a regulated 5V.
The 24AH / 88.8WH lithium pack supports up to 4 days of rainy or cloudy standby for typical low-power loads. Actual autonomy depends on the connected device’s daily consumption.
Yes. A built-in controller chip supports TTL protocol communication, so the controller can report battery level, charging state and output status to upper-level monitoring equipment.
