A UPS for CCTV: why you need one
Without electricity cameras do not film and the recorder does not record. An uninterruptible power supply closes that gap.

In short
What to know
- What happens without oneThe power goes out and the system stops. There will be no footage for that time.
- What to connectThe recorder, the switch and the router. Cameras powered over the network cable get their power through the switch, so they keep working too. Cameras with separate power supplies are connected to the UPS as well.
- How long it lastsThe time depends on battery capacity and on how much the whole system draws. It is calculated for the specific equipment.
- Voltage swingsMany UPS units also smooth out the surges and sags that harm disks and power supplies.
- Batteries ageBatteries lose capacity over time. Their condition is checked during servicing and they are replaced once the running time has clearly dropped.
Questions
Frequently asked questions
Is a UPS mandatory?
The system works without one. But if footage matters precisely at the moment the power goes out, you cannot do without it.
Is one UPS enough?
Yes, if the recorder, the switch and the router stand together — usually in one cabinet.
Who selects the UPS?
We do: we calculate what the system draws and select for the running time you need.
