With 59 million CCTV cameras(data from Statista/BSIA), the UK leads the world in surveillance density. But a reliable power supply is critical to the surveillance system. A leading UK security company solved its biggest operational headache in frequent maintenance and power downtime. By upgrading to custom 12V 30AH LiFePO4 batteries from VTCBATT, their security system achieved 40% longer runtime and 50% maintenance cost reduction. To date, over 1,000 units of LiFePO4 batteries for outdoor security cameras have been successfully installed across the UK security network. They have since upgraded their entire solar-powered surveillance infrastructure. This case study demonstrates how battery innovation can guard security system reliability.
The Challenge: Powering 24/7 Security Networks in the UK
Across the UK, home surveillance is no longer a luxury—it’s a critical device for crime deterrence and insurance compliance. But all the surveillance devices in UK households(such as wireless cameras, video doorbells, and alarms) rely on battery power.
Security providers operating in the UK contend with a unique set of operational hurdles:
-High Maintenance Cost: As the main backup or primary power supply, the traditional lead-acid batteries for security systems require frequent replacement within 1-2 years and regular voltage checks. For ordinary home users, it is a considerable burden.
-Poor Power Supply: Most CCTV cameras are installed in gardens, driveways, and garages. But those places are far away from electricity. Wireless cameras can receive the signal, but the power supply is a weak link.
-Installation Limit: Most UK households are of historical heritage. The installation should follow the BS EN 62676 standard. Traditional cameras need an electrician installation and a long period. Furthermore, it will even damage the construction of the house.
-Cold Weather: In the UK winter, the low temperature can reach -20°C.Traditional lead-acid battery performance struggles at below 0°C. Due to the power failure in cold weather, winter is the peak burglary season.
–Bulky Size: Traditional lead-acid battery dimensions are much larger and limit installation options.
–Unstable Voltage: Voltage fluctuations affected camera performance.
-Environmental Concerns: Lead-acid batteries have environmental disposal issues.
The security systems required reliable 24/7 power for continuous operation. It requires a stable voltage output and extra-long cycle life to reduce the maintenance cost.
Solution: Custom 12V 30AH LiFePO4 Battery
To address these operational limitations, VTCBATT engineered a custom design 12.8V LiFePO4 configuration.

3. Performance Comparison Table
LiFePO4 battery VS Lead-Acid battery
| Feature | VTCBATT LiFePO4 Advantage | Traditional Lead-Acid (SLA/AGM) |
| Cycle Life | 6,000+ Cycles | 300 – 500 Cycles |
| Energy Density | 40% higher capacity in the same footprint | Bulky and heavy for the same power |
| Self-Discharge | Ultra-low loss (<3% per month) | High loss (5% – 15% per month) |
| Maintenance | 100% Maintenance-Free | Requires venting and frequent checks |
| Depth of Discharge | Up to 100% without damage | Recommended max 50% to avoid failure |
| Charge Speed | 3x–5x Faster charging | Slow, multi-stage charging required |
What are the benefits of a Lifepo4 Battery Upgrade?
1. Ultra-long Longevity (Lower TCO)
The LiFePo4 battery has 6,000 cycles at 80% Depth of Discharge (DOD). A single VTCBATT battery outlasts approximately 10 to 12 lead-acid replacements. This drastically reduces the Total Cost of Ownership (TCO). It eliminates frequent labour and hardware costs.
2. Maximum Space Efficiency
Within the same dimensions, our high-energy-density design provides 40% more usable energy. Same enclosure. 40% more usable power. No new drilling.
3. Reliability
Due to sulfation, the traditional lead-acid batteries can only support partial discharge, while LiFePO4 maintains its integrity. The deep cycle LiFePO4 battery for security features an ultra-low 3% self-discharge rate; Even after long periods of standby, it can still keep your security system ready for action.
4. Environmental Resilience
In cold weather, the lead-acid performance drops sharply. While LiFePO4 cells are engineered for stability even under subzero conditions. Integrated with our Smart BMS, they provide consistent power delivery from -20°C to 60°C. During harsh winters, the reliable power supply ensures your security cameras maintain continuous operation.
“Because the panel uses minimal power anyway and because the battery lasts 6 months on a busy site without solar, the Vigileyez panel only needs a tiny 12-watt, 12 volt DC solar panel to keep it going indefinitely,even through the harshests of UK winters.
This new battery is on its way. The good news is it will work with existingpanels, no new panel needed and should be available in time for thewinter period. We will keep you posted.
