3-Pack Voice Doorbell, 1000m USB Charging Function, Smart Wireless Calling System, Waterproof Wireless Doorbell for Home and Office – ANPVIZ

• New wireless doorbell model with long range for home use, voice call, loud sound and clear two-way communication
• DOORBELL UNIT: The package contains 3 doorbell units that can switch between ring and two-way communication modes.
• LONG RANGE: The voice transmission range is up to 1000 m outdoors and 20 to 50 m through walls – very convenient.
• DISPLAY: The two-way communication units are user-friendly and equipped with an intercom and a power indicator, so users can see the status at a glance.

• 1. The actual measured talk range is 1000 meters on floors 1 to 8.
  
• 2. The design is slim and only 18 mm thick. Comparable products on the market are over 22 mm thick and fit well in the hand.
  
• 3. The battery is a 2000 mAh lithium battery. Both the outdoor and indoor units have original 2000 mAh batteries. The outdoor unit can be used up to 5 times a day, allowing 2 minutes of talk time per use. The battery life is approximately 8 months. The indoor unit works perfectly.
  
• 4. The buttons are made of a plastic-silicone combination, and the surface has a high-gloss UV finish that feels pleasant to the touch. Compared to competing products that use buttons made entirely of rubber, these do not feel high-quality or provide a good grip.
  
• 5. Intelligent and user-friendly design with intercom illumination and power indicator allows the customer to see the status at a glance.
  
• 6. Two indoor units can switch between ringtone and intercom modes and be used as an intercom system!
  
• 7. The outdoor unit can be charged in two ways: via direct current (DC) without removing the waterproof cover or on the charging cradle.
  
• 8. The power switch is in position 0 and turns the unit off. Positions A and B correspond to frequency B. In case of interference during a call, the outdoor and indoor units simultaneously switch to position A and B, respectively. 9. Two intercom modes are available between the two indoor units. 1. In standard mode, press the internal call button on one of the indoor units. The other indoor unit will ring. Then, press and hold the talk button to start an intercom call. 2. In the second mode, the internal call button is not required. Simply press and hold the talk button to speak.
  To switch between the two modes: Press and hold the internal call button for 5 seconds. You will hear 3 beeps.
