Application Background
Wireless doorbell cameras must operate outdoors under variable temperatures and frequent wake-up cycles. Key requirements include:
- Long standby life (3–12 months depending on use)
- High pulse discharge for Wi-Fi transmission
- Stable voltage for camera + PIR sensor
- Compact size for slim ID designs
- High safety and global certification compliance
- Wide temperature performance −20°C to 60°C
Many brands experience issues like short runtime, cold-weather shutdowns, and difficulty sourcing custom-shaped batteries. PKNERGY’s engineering team solves these challenges with tailored lithium-ion and Li-polymer packs.
