I. High-Definition Camera Technology: The Integration of Optics and Digital Imaging
The wireless video intercom doorbell's high-definition camera combines advanced optical lenses with image sensor technology. The lens captures light and focuses it onto the sensor, which converts the optical signals into electrical signals, resulting in digital images. This process involves the physics principles of light refraction, reflection, and the photoelectric effect.
High Resolution: Ensures rich image details, facilitating the identification of visitors. Our 7-inch wireless video doorbell boasts a resolution of 1024600, while the 8-inch model offers 1280800 resolution.
Wide Dynamic Range: Adapts to varying light conditions, maintaining a balanced image brightness.
II. Audio Communication Technology: Digital Processing and Transmission of Sound
High-sensitivity microphones capture sound signals, which are converted from analog to digital audio signals by Analog-to-Digital Converters (ADC). These digital signals are then transmitted wirelessly as electromagnetic waves to the indoor unit. The indoor unit receives the signals and restores them to analog audio signals through Digital-to-Analog Converters (DAC), allowing users to hear clearly.
Low Noise Design: Reduces environmental noise interference, enhancing call clarity.
Real-Time Communication: Ensures audio signals are transmitted without delay, improving communication efficiency.
Anti-Interference Capability: Utilizes advanced modulation and demodulation techniques to resist signal interference.
III. Infrared Night Vision Technology: Monitoring in the Dark with Infrared Light
Infrared night vision lights emit invisible infrared light, which is reflected by objects and captured by the infrared sensors within the camera. These sensors, sensitive to infrared light, convert the reflected light into electrical signals, forming night vision images.
Long-Range Illumination: Ensures clear monitoring even at night or in low-light conditions.
Smart Sensing: Automatically adjusts infrared light intensity based on ambient light, conserving energy.
Concealment: Invisible infrared light avoids disturbing visitors or drawing attention.
IV. Wireless Communication Technology: Ensuring Stable Transmission
The wireless transmitter encodes and compresses video and audio signals, sending them as electromagnetic waves through wireless channels (such as Wi-Fi) to the indoor unit. The receiver then demodulates and decodes the signals to restore the original content.
Long-Range Stable Transmission: Ensures signals remain stable and high-quality over long distances.
Anti-Interference & Security: Implements encryption and channel coding to prevent signal theft or interference.
Low Power Design: Optimizes transmission protocols and hardware design, reducing device energy consumption.
V. Waterproof and Dustproof Design: Withstanding Harsh Environments
Constructed with high-strength, corrosion-resistant materials and a sealed design, the waterproof and dustproof enclosure effectively blocks moisture and dust from entering the device, safeguarding internal components.
Durability: Ensures the device functions normally even in severe environments.
Ease of Cleaning: Facilitates routine cleaning and maintenance.
Eco-Friendly Materials: Selected to minimize environmental impact.
In conclusion, the wireless video intercom doorbell integrates advanced technologies like high-definition cameras, audio communication, infrared night vision, and wireless transmission, providing comprehensive protection for home security. Its high-definition camera ensures rich image details, audio communication technology enhances call clarity and real-time communication, and infrared night vision capabilities allow for unhindered night monitoring. The stability and anti-interference capabilities of wireless communication technology guarantee the quality and security of signal transmission. Furthermore, the waterproof and dustproof design makes the device adaptable to various harsh environments, extending its service life. Thus, the wireless video intercom doorbell serves as an indispensable security guardian for modern smart homes, bringing peace of mind and convenience to families.
