The smart wireless video doorbell plays a crucial role in home security, especially in nighttime monitoring. This article will delve into the key technologies of night vision enhancement in smart wireless video doorbells: infrared light sources and image enhancement techniques. By detailing the principles, applications, and future trends of these technologies, we aim to provide readers with comprehensive insights into the battery technology of smart doorbells and offer guidance for selection and usage.

Battery Types

Smart wireless video doorbells typically use lithium batteries or rechargeable nickel-metal hydride (NiMH) batteries as power sources. These batteries have the following characteristics:

Lithium Batteries: Lithium batteries boast high energy density, lightweight, and long lifespan. Due to their small size and light weight, they are suitable for lightweight and portable devices like doorbells.

Rechargeable Nickel-Metal Hydride Batteries: Rechargeable NiMH batteries are relatively cost-effective and environmentally friendly, capable of withstanding multiple charge-discharge cycles, making them suitable for doorbell devices that require long-term operation.

Example: A smart wireless video doorbell is equipped with high-performance lithium batteries as power sources, ensuring stability and durability during prolonged usage.

Battery Capacity

The battery capacity should be chosen based on the power consumption and working time of the doorbell device to ensure continuous operation without external power supply. Typically, the battery capacity of doorbell devices should meet the following requirements:

Working Time: Determine the required duration of continuous operation for the doorbell device based on user needs and usage scenarios, such as one day, one week, or one month.

Power Consumption Evaluation: Evaluate the power consumption of the doorbell device, including standby, monitoring, and communication states, to determine the required battery capacity.

Example: The design goal of a smart wireless video doorbell device is to operate continuously for one month in standby mode and one week in monitoring mode. Based on power consumption evaluation, the required battery capacity is determined to be XXXmAh.

Battery Management System

Smart doorbell devices require effective battery management systems to ensure battery safety, stability, and longevity. The battery management system typically includes the following functions:

Battery Status Monitoring: Real-time monitoring of key parameters such as battery voltage, temperature, and remaining capacity to detect battery status anomalies promptly and take appropriate measures.

Charge-Discharge Management: Control of the charging and discharging processes of the battery, including regulating charging current, voltage, and duration, to protect the battery from overcharging or overdischarging.

Temperature Control: Adjustment of the device's operating status based on battery temperature changes to prevent battery overheating or chilling damage.

Battery Protection Functions: Timely disconnection of the battery from the device in case of overload, short circuit, or overheating to ensure the safety of the device and battery.

Example: A smart wireless video doorbell is equipped with an intelligent battery management system capable of real-time battery status monitoring, adjustment of charge-discharge parameters based on operating status, and timely protection measures in case of anomalies, ensuring the safety and stability of the device.


The battery component of the smart wireless video doorbell is one of the core elements that directly affect the device's prolonged operation and safety. By selecting appropriate battery types, capacities, and equipping effective battery management systems, doorbell devices can operate stably and reliably in various usage scenarios. In the future, with continuous technological innovation and development, battery components will become more intelligent and efficient, offering more possibilities for performance improvement and user experience enhancement in smart doorbell devices.
