Image Sensor: 1/2.8” (or 1/3″) 2-Megapixel Progressive Scan CMOS Sensor.
Max. Resolution: 1920 × 1080 (1080p Full HD).
- Note: Some newer versions or regional variants might offer 2K+ (2560 x 1440 or 4MP) resolution, often marketed as BC1-B1 2K+ etc. The core features remain similar.
Lens: 2.8mm @ F1.6
- Viewing Angle: Typically $12 8^{\circ}$ (Diagonal), $10 8^{\circ}$ (Horizontal), $6 0^{\circ}$ (Vertical) for the 1080p model. For 2K+ models, it might be $11 6^{\circ}$ (Diagonal), $10 0^{\circ}$ (Horizontal).
Minimum Illumination: 0.2 Lux @ (F1.6, AGC ON), 0 Lux with IR.
Night Vision:
- IR (Black & White) Night Vision Distance: Up to 10m (32 ft).
- Color Night Vision: Yes, thanks to two built-in spotlights, the BC1 can render vivid color images even in pitch-black darkness. This allows you to see crucial details that would otherwise be lost. It supports Smart Night Vision (switches to color upon human detection).
WDR (Wide Dynamic Range): DWDR (Digital Wide Dynamic Range).
DNR (Digital Noise Reduction): 3D DNR.

Video & Audio:

Video Compression: H.265 / H.264 (H.265 Main Profile for more efficient video storage and lower bandwidth usage).
Frame Rate: Max. 15fps; Self-Adaptive during network transmission.
Video Bit Rate: FHD; Hi-Def. Adaptive bit rate.
Audio Bit Rate: Self-Adaptive.
Max. Bitrate: 2 Mbps.
Two-Way Talk: Supported, with a built-in omnidirectional microphone and loudspeaker, allowing for real-time communication.
Customizable Voice Alerts: You can pre-record voice messages to be played automatically upon detection.

Network (Camera to Base Station):

Wireless: Built-in 2.4G Wi-Fi for communication with the base station.
Protocol: EZVIZ Cloud Proprietary Protocol.
No Direct Router Connection: The BC1 camera must be paired with the included EZVIZ Base Station (W2H-B) and cannot directly connect to your home Wi-Fi router.

Functions & Features:

Battery-Powered: Equipped with an impressive 12,900 mAh rechargeable lithium battery.
- Battery Life: Advertised up to 365 days (one year) on a single full charge. This data comes from strict tests in the EZVIZ lab under standard conditions (e.g., 5 minutes of usage per day). Actual use may vary significantly due to environmental factors and the frequency of camera activities (more motion, live viewing, etc., will reduce battery life).
Smart Alarm:
- Smart Human Motion Detection: Incorporates a PIR sensor and AI algorithm to accurately distinguish human shapes from other moving objects, significantly reducing false alarms.
Active Defense: Upon detecting a person, the BC1 can automatically set off a loud siren (up to 105 dB or 125 dB on base station) and flash its two spotlights to deter intruders.
Weatherproof Design: IP66 Rated. This means it is highly protected against dust and powerful jets of water, making it very durable for outdoor use.
Flexible Installation: Comes with both a magnetic base (for easy removal for charging) and a screw-in base for more secure, fixed installation.
Solar Panel Compatibility: Can be connected to an optional EZVIZ Solar Charging Panel (compatible models, usually Type-C connection) for continuous trickle charging, extending battery life indefinitely.
Smart Integration: Compatible with Google Assistant and Amazon Alexa.

Storage (Managed by Base Station):

Local Storage: The Base Station (W2H-B) includes a microSD card slot that supports cards up to 256 GB. This ensures data security even if the camera itself is damaged or stolen.
Cloud Storage: Supports EZVIZ CloudPlay storage (subscription required).

Base Station (W2H-B) Parameters:

Camera Pairing: Supports up to 4 EZVIZ battery-powered cameras (like BC1, EB3, etc.).
Buttons: Sync button, Power button, Reset button.
Indicators: RGB LED indicators, Network indicator.
Network Interface: 1 RJ45 10M / 100M Adaptive Ethernet WAN interface (the base station connects to your home router via Ethernet).
Wireless Interface: Built-in 2.4G Wi-Fi to communicate with the cameras.
Power: DC 12V / 1A.
Siren: Built-in siren, often rated at 125 dB.
Dimensions: $81.97 \times 63.97 \times 160.22 mm$ ( $3.23 \times 2.52 \times 6.31 inch$ ).
Weight: 207 g (7.30 oz).

General (Camera):

Operating Conditions: $- 2 0^{\circ} C$ to $5 0^{\circ} C$ ( $- 4^{\circ} F$ to $11 3^{\circ} F$ ), Humidity 95% or less (non-condensing).
Power Supply: 12900mAh Rechargeable Lithium Battery (or 5V DC via USB for charging).
