Technical specifications list this device as a digital-mechanical viewer utilizing a 3.5-inch TFT LCD with a resolution of 480x320 pixels. The imaging system is built around a 1.0MP CMOS sensor that operates without wireless protocols such as Wi-Fi, Zigbee, or Bluetooth. Aggregated data indicates the unit fits standard door bores ranging from 14mm to 28mm.
The system's power architecture is dual-compatible, supporting either four AAA batteries or a 1200mAh Li-ion cell. Performance metrics demonstrate a nominal runtime of 30 to 60 days under standard cycling. Material analysis identifies the primary data link as a thin Flexible Printed Circuit (FPC) that is susceptible to shearing stress from frequent mechanical door vibrations. Local data storage is facilitated via a MicroSD slot supporting up to 32GB of proprietary format files.
Performance metrics confirm instant-on display activation upon manual button engagement, bypassing the latency typical of cloud-tethered alternatives.
- Connectivity: 0% network dependency; local-only circuit.
- Optical profile: Fixed-focus CMOS with short-range infrared support (1.5m).
- Installation: Mechanical compression fit with standard hardware.
For installations requiring remote monitoring capabilities missing from this model, the Cawhun WiFi Peephole Camera with 2-Way Talk provides a networked alternative for real-time mobile interaction.
This hardware is situated within the smart peephole cams market as a non-networked digital transition for traditional optical peep-sites.
