Introducing the electronic door viewer with photo capture function by Spreest — a modern device that will enhance the comfort and security of your home, apartment, or office. With it, you no longer have to bend down to look through a traditional peephole, gaining a full view of what's happening outside your door.

Additionally, the device functions as a doorbell and allows you to record visitors. The built-in memory can store up to 40 photos, and once full, the oldest photos are automatically overwritten. This is the only model on the market with a built-in battery that can operate for up to 120 days on a single charge.

It fits doors with a thickness of 35-120 mm.

Key features

1. Excellent craftsmanship and modern design: The elegant appearance makes the device perfectly blend into any interior.

2. 2.4" color LCD display: A large and clear screen ensures comfortable use.

3. Wide viewing angle 90°: A super wide lens allows you to see more.

4. Night mode: Built-in 2 infrared LEDs enable vision in complete darkness up to 5 meters.

5. Doorbell function: When you press the doorbell button, you will hear a pleasant signal, and the viewer will take and save a photo in the device's memory.

6. Built-in memory for 40 photos: Automatic overwriting of the oldest photos when memory is full.

7. Built-in 600 mAh battery: Long-lasting operation without frequent charging (charging cable included).

8. Universal mounting: Fits 99% of available doors with a thickness of 35-120 mm.

9. Simple and non-invasive installation: Quick installation without the need for specialized tools.

Easy installation in 4 steps

  1. Prepare the viewer: Choose a screw of appropriate length for your door thickness and screw it into the hole on the back of the viewer.
  2. Place the viewer in the door: Insert the viewer into the hole in the door, ensuring that the signal cable and screws protrude on the other side.
  3. Mount the frame: Thread the signal ribbon through the upper slot and the screws through the lower slot of the metal frame. Tighten the screws to stabilize the viewer and frame.
  4. Connect the display: Plug the signal connector into the display's socket and slide the display onto the frame on the door.

Safety and convenience

The electronic peephole makes it easy to monitor daily who is at your door. You no longer have to bend down and peer through a traditional peephole.

The device automatically saves photos of people ringing your doorbell, so even when you're away, you know who visited you. Additionally, during viewing, you can manually take a photo of the situation outside the door.

The display stays on for too short a time, in my opinion. Slow to wake up.

+Compact and easy to install.

Easy to install. The only downside is that it’s hard to see in low light and practically impossible in the dark
