CCTV During Power Outages in Kenya: How to Keep Cameras Recording
Power interruptions are a fact of life in many parts of Kenya, from brief flickers to blackouts that last hours. For security, blackouts are a double problem: darkness makes compounds and shops more vulnerable, and many CCTV systems switch off exactly when they are needed most. Criminals know this, and some break-ins are timed for outages or even follow deliberate tampering with the power supply. Planning for CCTV during power outages is therefore essential, not optional.
This guide explains what happens to CCTV when power fails, how to size and install backup power, how solar and inverters fit in, and how to protect your system from surges when power returns.
What happens when power fails
| Component | Without backup |
|---|---|
| Cameras | Switch off; no video recorded |
| Infrared night vision | Off with the camera |
| Recorder (DVR/NVR) | Stops recording; may corrupt files or damage the hard drive if power cuts abruptly |
| Router | Internet drops; no remote viewing or alerts |
| Security lights | Off, leaving the compound dark |
| Alarm panel | Usually has its own battery, but check it |
When power returns, voltage surges can damage power supplies, cameras and recorders. Frequent outages and surges shorten equipment life.
The basic solution: a UPS
An uninterruptible power supply (UPS) is a battery unit that keeps equipment running instantly when power fails. For CCTV during power outages, a UPS should support:
- The recorder
- All camera power supplies (or the PoE switch for IP cameras)
- The internet router
- Any guardhouse monitor

Sizing a UPS
The runtime you get depends on the total power drawn by the equipment and the capacity of the UPS batteries. An installer should add up the power consumption of the recorder, cameras, infrared, router and monitor, then choose a UPS and battery capacity to match your target runtime.
| Target runtime | Suits |
|---|---|
| 30 minutes to 1 hour | Areas with short, occasional outages |
| 2 to 4 hours | Areas with regular outages; most homes and shops |
| 6 hours or more | Frequent long outages; businesses and estates; usually needs external batteries, an inverter or solar |
Note that infrared at night increases camera power use, so night runtime is shorter than daytime.
Options for longer backup
UPS with external batteries
Many UPS units accept extra external batteries for longer runtime. This is a common approach for businesses and estates.
Inverter and battery bank
A home or office inverter with a battery bank can power CCTV along with lights and other essentials during long outages. Make sure the inverter provides clean power suitable for electronics.
Solar backup
Solar panels charging a battery bank can keep CCTV running for long periods and reduce reliance on the grid. This works well for sites with frequent or long outages, farms and remote properties. See solar CCTV cameras in Kenya.
Generators
Generators can power sites for extended outages, but they take time to start. Use a UPS to bridge the gap so recording never stops.
Choosing the right backup
| Situation | Suggested backup |
|---|---|
| Small home, occasional outages | UPS for recorder, cameras and router |
| Shop with regular outages | UPS with extended runtime |
| Office or warehouse | UPS with external batteries, plus generator if available |
| Estate gate and perimeter | UPS plus solar or generator |
| Farm or remote site | Solar-powered cameras or solar battery system |
Protecting cameras’ power supplies
- Use a centralised power supply box for cameras, connected to the UPS
- For IP systems, a PoE switch or NVR on the UPS powers all cameras through one cable each
- Avoid plugging individual camera adaptors into random sockets around the building
Surge protection and earthing
Surges when power returns, and lightning during storms, damage CCTV equipment. Protect your system with:
- Surge protection on the incoming power supply
- A UPS that filters power
- Proper earthing of the electrical system
- Surge protectors on long outdoor cables where lightning is common
- A voltage stabiliser in areas with frequent fluctuations
Don’t forget the router and lights
A recorder that keeps recording but cannot send alerts is only half the solution. Put the router on the UPS so remote viewing and alerts keep working. Also consider battery or solar backup for key security lights, so cameras can see and the compound is not in total darkness. See security lighting for homes.
Hide and secure backup equipment
A UPS or battery bank in an obvious place can be switched off by an intruder. Keep the recorder, UPS and router in a locked, hidden location.
Deliberate power tampering
Some criminals switch off the main power at the meter or cut cables before a break-in. Protect against this by:
- Locking meter boxes and main switches where possible
- Keeping CCTV on a UPS so it records the tampering
- Linking power failure alerts to your phone or an alarm response team
- Having guards check the power supply during their rounds
Alarms and outages
Most alarm panels have their own backup battery, but it may be old. Test your alarm during a power cut and replace batteries as needed. A monitored alarm connected to a response team can alert you to power failure and intrusion. See our alarm response services.
Maintenance of backup systems
| Task | How often |
|---|---|
| Check UPS status indicators | Weekly |
| Test runtime by simulating an outage | Every few months |
| Replace UPS batteries | Every few years or when runtime drops |
| Check inverter and solar batteries | Monthly |
| Inspect surge protection | After storms and yearly |
See CCTV maintenance checklist.
Common mistakes
- No UPS at all, or a UPS only on the recorder
- Router not on backup, so no remote viewing during outages
- Old UPS batteries that last only minutes
- No surge protection
- UPS placed where an intruder can switch it off
- Never testing the backup
Worked example: a hardware shop in Kitengela
A hardware shop in Kitengela suffered a break-in during a night-time power cut. The cameras had gone off with the power, and there was no footage. The shop installed a UPS with external batteries sized for about four hours of night-time operation, covering the DVR, eight cameras and the router, added surge protection, and placed the equipment in a locked cabinet. Power failure alerts were sent to the owner’s phone. Months later, a second attempt during an outage was recorded clearly and the owner was alerted in real time.

Planning backup for your area
Outage patterns vary across Kenya. Some neighbourhoods see brief daily interruptions, others occasional long blackouts, especially during storms. Keep a simple record of outages at your property for a month: how often they happen and how long they last. This helps your installer size backup for CCTV during power outages accurately instead of guessing, and avoids paying for more capacity than you need or, worse, too little.
Priorities when budget is limited
If you cannot back up everything, prioritise in this order:
- The recorder, so recording continues and the hard drive is protected
- Cameras at the gate, main doors and tills
- The router, so alerts and remote viewing continue
- Key security lights at the gate and doors
- Remaining cameras and monitors
This ensures the most important evidence is captured even with a modest UPS.
Testing your backup properly
Do not wait for a real blackout to discover your backup does not work. Every few months, switch off mains power to the CCTV circuit at night, when infrared increases demand, and time how long the system keeps recording. Check that cameras, recorder and router stay on, that alerts still reach your phone, and that recording resumes cleanly when power returns. Note the result in your maintenance log and replace batteries when runtime drops.
Power-saving settings
Some settings stretch runtime during outages: recorders can switch unused cameras to lower frame rates, and motion recording on less critical cameras reduces load on the recorder. Avoid turning off infrared on key cameras, since night footage is often the most important.
Frequently asked questions
Does CCTV work during power outages?
Only if it has backup power such as a UPS, inverter or solar system.
What size UPS do I need for CCTV?
It depends on the power drawn by your recorder, cameras and router and how long you need it to run. An installer should calculate it.
How long will a UPS run my cameras?
From minutes to several hours, depending on load and battery capacity. External batteries extend runtime.
