Even a short power interruption can restart a router, disconnect remote users and stop live access to CCTV cameras. In offices, shops, warehouses and homes, the main problem is not always the duration of the outage. Repeated shutdowns and long restart times can interrupt communication exactly when it is needed most.
Why network equipment stops during an outage
Routers, modems, access points and many CCTV cameras operate on low-voltage DC power. When the main electricity supply fails, their adapters stop immediately. A conventional large UPS can protect complete systems, but it may be oversized when the requirement is only to keep a few low-power devices online.
A Mini DC UPS is designed for this specific situation. It stores energy in an internal battery and supplies compatible DC, USB or PoE equipment when mains power is interrupted. The transition is automatic, so supported devices can continue operating without a manual restart.
Problems a Mini DC UPS can solve
- Loss of internet and local network access during power interruptions.
- Temporary loss of remote CCTV viewing and camera connectivity.
- Repeated router and modem restarts caused by unstable electricity.
- Downtime for low-power access points, optical network terminals and supported PoE devices.
- Unnecessary use of a large AC UPS for a small DC load.
Check compatibility before choosing a model
The correct model depends on the connected equipment. Before installation, check the voltage, current, connector type and total power consumption shown on every device or power adapter.
- Match the voltage: the UPS output voltage must match the device requirement.
- Check total power: add the power requirements of all connected devices and keep the combined load within the UPS rating.
- Confirm polarity and connector size: a physically similar plug is not always electrically compatible.
- Verify PoE voltage: if PoE output is required, confirm whether the connected equipment needs 24V or 48V and whether it is compatible with the available output.
- Estimate runtime realistically: operating time varies with battery capacity, device load, battery condition and environmental temperature.
SyscomX solutions for different backup requirements
The SyscomX MINI DC UPS SX-UPS 12000 is a compact option for routers, modems, Wi-Fi devices, CCTV cameras and compatible low-power PoE equipment. It combines an internal lithium battery with multiple DC outputs, USB and PoE output for flexible small-network backup.
For applications that need a larger battery and more output options, the SyscomX MINI DC UPS SX-UPS 20000 includes a built-in 20000mAh LiFePO4 battery, DC outputs, USB, Type-C and selectable 24V/48V PoE output. Its maximum output power is 18W, so the total connected load must remain within that limit.
Recommended installation approach
- List every device that must remain online.
- Record the voltage and power requirement for each device.
- Select only compatible outputs and cables.
- Connect the UPS to mains power and allow it to charge according to its instructions.
- Test the setup by safely disconnecting mains power and confirming that every critical device remains stable.
- Label each output cable to prevent incorrect reconnection during maintenance.
Where this solution is most useful
Mini DC UPS units are particularly useful for home and office internet, small CCTV systems, retail shops, remote monitoring points, reception areas and network cabinets containing a small number of low-power devices.
Build a more reliable network
Backup power should be selected as part of the network design, not after the first outage. SyscomX can help identify the suitable Mini DC UPS model based on device voltage, load and required connections.
