UPS supports the camera, but not the switch or router
NETWORK OUTAGE SECURITY
Backup Power for Critical Devices
Calculation and installation of backup for the controller, communication, sensors, cameras, intercom, locks, and other truly important loads. Design, Installation and Maintenance in Almaty and Kazakhstan.
MAIN RESULT
The backup should support not the entire house out of habit, but predefined safety functions for a set period. We calculate the load, inrush currents, battery degradation, and priorities.
HOW THIS WORKS IN REAL LIFE
A scenario understandable without technical terms
Electricity was cut off in the area. Cameras, recorder, router, Home Safety controller, and intercom continue to operate. The owner receives a message about switching to backup and knows in advance the expected autonomy time.
WEAKNESSES
Why a separate device is not enough
Location, communication, power, reaction logic, and maintenance determine reliability—not just the brand of the sensor or actuator.
Passport time calculated without real load
An old battery gives the appearance of a backup
After discharge, the system turns on in the wrong sequence
ENGINEERING SCENARIO
What We Design & Inspect
Each step should have a clear result and manual verification method.
- 01
Compiling a list of critical devices and their actual power
- 02
Determine the required operating time and permissible outages
- 03
We select the architecture of the UPS, DC backup, or battery system
- 04
Checking the transition, full cycle and correct power restoration
IMPORTANT IN THE PROJECT
What must be addressed from the start
- Accounting for start-up currents of drives and network equipment
- Separate Load Groups by Priority
- Monitoring battery conditions and temperature
- Safe installation, line protection, and serviceability
TRANSFER TO OWNER
What you receive beyond the equipment
- Critical Loads Table
- Expected autonomy calculation
- Transfer to reserve indication
- Proven Shutdown Test
- Battery Replacement and Diagnostics Regulations
BEFORE INSTALLATION
Questions: backup power
Short answers to questions that affect the composition, cost, and reliability of the solution.
01How many hours will the backup power last?
This depends on total power, capacity, efficiency, temperature, and battery condition. First we measure or confirm the load, then calculate several autonomy scenarios.
02Can only cameras and internet be left running?
Yes, but the entire chain must be included: cameras, PoE switch or power units, recorder if necessary, router, and provider equipment on the house side.
03Will a regular computer UPS do?
Sometimes for a small load, but it is necessary to check the voltage waveform, power, operating time, cooling, battery replaceability, and correctness with specific equipment.
04How do I know if the battery is still working?
Age cannot be judged precisely. A load test, voltage monitoring, discharge time, and self-diagnosis messages are required. Such a test is included in maintenance.
05Can I connect solar panels?
Yes, if the task requires longer autonomy and a compatible inverter circuit is chosen. For short outages, a simple backup may be more rational than a full solar system.
06What happens after a full discharge?
The system must correctly disable sensitive devices and start up in a safe sequence after network recovery. We test this scenario during commissioning.
ENGINEERING CONSULTATION
