1. Core Selling Points

1. All-Weather Security Protection：IP65 waterproof rating and -10~55℃ wide temperature operating range ensure stable performance in heavy rain, high temperatures, or low temperatures. No need to worry about environmental impacts for outdoor installation.

2. 8m Accurate PIR Detection：8-meter human motion detection distance, exceeding the industry average, combined with human detection technology. It accurately identifies visitors or abnormal movements, reducing false alarms and never missing important situations.

3. 2K HD Visual Experience：3MP (2K) HD resolution delivers clear and detailed daytime images. Equipped with 6 high-power 940nm infrared LEDs, it provides 5-10m night vision range, ensuring clear black-and-white images at night with no monitoring blind spots day and night.

4. Wireless Easy Installation：2.4G wireless connection design eliminates complex wiring. You can complete the installation by yourself, saving on on-site installation costs. It can also be easily disassembled and taken away when moving.

2. Experience Upgrade Highlights

1. Second-Level Response Interaction：Three wake-up methods - remote wake-up via mobile phone, PIR detection wake-up, and doorbell button wake-up. Notifications are delivered in seconds. When a visitor presses the bell, your mobile phone receives an alert immediately, avoiding missing important visitors.

2. Full-Duplex Two-Way Audio：Built-in high-sensitivity microphone and 8Ω1W speaker support full-duplex two-way audio. With echo cancellation technology, calls are clear and delay-free, just like face-to-face communication. It facilitates scenarios such as courier collection and visitor communication.

3. Dual Storage Protection：Supports up to 256GB TF card local storage and provides 3-day free cloud storage. Local and cloud dual backup ensures that even if the device is lost, important videos can be retrieved from the cloud, making data more secure.

4. Tamper-Proof Alarm Design：Built-in tamper-proof button. If someone attempts to illegally disassemble the device, it will immediately trigger an alarm and push an alarm notification to the mobile phone, effectively preventing device theft or damage and enhancing security levels.

3. Practical Additional Value

1. Multi-User Shared Viewing：Supports 4 users to watch online simultaneously. Family members can manage it together. When the elderly or children are at home alone, other family members can check the situation at the door in real time, providing more peace of mind.

2. Optional 433 RF Chime：Can be matched with a 433-RF indoor chime. Even if the mobile phone is not around or the signal is poor, you can hear the doorbell ring indoors, avoiding missing visitors due to silent mobile phones.

3. Low Power Consumption & Long Battery Life：5000mAh large-capacity battery with only 160uA standby current. It has a long battery life under normal use, reducing the trouble of frequent charging, which is worry-free and labor-saving.

4. Future AI Upgrade：Human detection is already supported, and more AI functions such as pet, vehicle, and package recognition are under beta testing. New functions can be obtained through firmware upgrades in the future, making the device smarter and continuously improving its use value.
