Basis and sources
- Ceylanpınar: 49.0 °C on July 25, 2025 and 47.8 °C on June 20, 2024 (MGM data, news sources)
- Recorder operating temperatures vary by model; one example model is rated 0 to +40 °C, indoor use only (Ajax NVR specifications)
- In lead-acid batteries, every 10 °C above 25 °C cuts battery life roughly in half (Schneider Electric)
- Calculation assumptions: IP camera 6 W (with infrared at night), recorder 12 W for up to 4 cameras, then +8 W for every additional 8 cameras, alarm/modem 8 W per device; inverter efficiency 85%, lead-acid battery 50% usable capacity.
