How to Secure Your Home During Load Shedding

Load shedding is not just an inconvenience — it is a security event. The moment the power goes out, electric fences deactivate, automated gates stop working, alarm sirens lose backup power, and CCTV systems go dark. Criminals know this. In fact, crime statistics in South Africa consistently show spikes during load shedding periods, particularly residential burglaries and vehicle theft from properties with motorised gates.

The Vulnerabilities Load Shedding Creates

Understanding the specific vulnerabilities helps prioritise your response:

• Electric fence failure: Most electric fences run on mains power with a small battery backup of 2 to 4 hours. Extended Stage 4 or 6 shedding drains these batteries completely.
• Gate motor lockout: When a gate motor battery dies, the gate either stays locked (trapping you inside) or opens freely (letting anyone in). Both are dangerous.
• CCTV blackout: Basic CCTV DVRs without UPS backup stop recording the moment power fails — precisely when you are most vulnerable.
• Alarm siren drain: Alarm panels have battery backup, but during extended outages the batteries deplete. Some systems also stop communicating with monitoring centres if the cellular or ADSL link relies on mains power.
• Lighting failure: Dark perimeters are exploited by criminals. Motion-activated lights without battery backup become useless during outages.

Building a Load Shedding Proof Security System

1. UPS Backup for Your NVR and Cameras

A UPS (Uninterruptible Power Supply) keeps your security cameras and NVR recording through a power cut. A basic 600VA UPS will typically run a 4-camera system for 4 to 6 hours — enough to cover most load shedding stages. For longer outages, a larger UPS or a lithium battery backup system is recommended.

2. Solar or Battery Gate Motor

Gate motors with built-in solar charging or large battery backup capacity can operate for days without mains power. This prevents the dangerous situation of a gate that opens freely when the battery dies. Look for motors with a minimum 80Ah battery capacity.

3. Electric Fence Backup Power

A dedicated UPS or solar panel feeding your energiser keeps your perimeter fence live through load shedding. Some modern energisers have built-in solar inputs — a worthwhile upgrade.

4. Local AI Processing — Not Cloud Dependent

This is where AI security systems with local processing (like the AI Vision Pro NVR) have a critical advantage. Because all video analysis happens inside the NVR on your property rather than in a cloud data centre, your AI surveillance continues to function as long as your UPS keeps the local system powered. Cloud-dependent systems, by contrast, lose all AI functionality when the internet goes down.

5. Battery-Backed Motion Lighting

Solar-charged LED floodlights with built-in batteries maintain your perimeter lighting through any outage. These are cost-effective and require no wiring changes.

The Automation Advantage

A smart home automation platform integrated with your security system can automatically respond to a power outage — locking doors, activating battery-powered lighting, and sending you an immediate alert. When power returns, the system can confirm all security components have resumed normal operation.

What to Do During a Load Shedding Security Event

If you suspect a security breach during load shedding, the priority actions are:

1. Stay inside and do not approach gates or perimeter walls
2. Alert your armed response company immediately — do not wait for the alarm to trigger
3. Use your phone to check camera footage if your system has mobile access
4. Sound your vehicle panic alarm if you need to alert neighbours quickly

Long-Term Planning

South Africa's power situation requires homeowners to treat load shedding security not as a temporary problem but as a permanent reality to plan around. A properly designed AI security system with UPS backup, local processing, and smart automation removes load shedding as a meaningful vulnerability — and gives you the same protection at Stage 6 as at Stage 0.
