CCTV UPS Backup Time Calculator – Estimate Runtime for DVR/NVR and Cameras
When it comes to CCTV security systems, uninterrupted power is critical. Power cuts or voltage fluctuations can put your surveillance setup at risk. That’s why most installations use a UPS (Uninterruptible Power Supply) with batteries to keep DVRs, NVRs, and cameras running during outages.
But how do you know how long your UPS will last with your current battery setup? That’s where the CCTV UPS Backup Time Calculator comes in.
🔧 What Does This Tool Do?
This online calculator helps you quickly estimate:
- Total power consumption of all connected CCTV devices (DVR/NVR, HDD/SSD, IP/Analog Cameras, Network Switches, etc.).
- Estimated battery backup time for common battery sizes (Ah).
- Required battery capacity (Ah) if you want a specific backup time in hours.
🖥️ How to Use the Calculator
- Add Devices – Select device type (DVR/NVR, Camera, Switch, etc.), enter power consumption (in watts), and quantity.
- Battery Settings – Choose battery voltage (12V or 24V), enter inverter efficiency (%) and DOD (Depth of Discharge %).
- (Optional) Enter required backup time in hours if you want to know the exact Ah capacity needed.
- Calculate – Get instant results showing:
- Total system wattage
- Estimated runtime for common battery sizes (65Ah, 100Ah, 150Ah, 200Ah)
- Required battery size for your desired backup hours
You can also export results as CSV or copy them for documentation.
📊 Why Is This Important?
- Helps in choosing the right UPS and battery size for your CCTV system.
- Avoids under-sizing (short backup) or over-investing in unnecessary large batteries.
- Useful for security installers, IT admins, and home/office CCTV owners.
✅ Key Features
- Supports DVR/NVR, HDD/SSD, Cameras, Switches, and custom devices.
- Works for both 12V and 24V battery setups.
- Flexible and easy-to-use interface.
- Export/Copy results for record keeping.
- Free, fast, and available online.
