SIP Video Door Phone Snapshot Function Guide: trigger events (call/ring/answer/unlock), upload to HTTP/FTP/TFTP, setup steps, troubleshooting for Bi30 series.
This document describes the snapshot function of SIP video door phones and intercoms. The snapshot function captures camera images when the device is triggered by events, then uploads images to a specified server. Supported servers: HTTP/HTTPS, FTP, TFTP. Supported triggers: call, ring, answer, unlock, etc.
Video Door Phones: Bi30, Bi31S, Bi32V, Bi33V
Video Intercoms: BK-DAB-PA2 + PA KIT Camera, BK-DAB-PA2S + PA2 KIT Camera, BHP-SOS10, BHP-SOS10V, BHP-SOS16, BHP-SOS16V, BHP-SOS18
The snapshot function captures images under predefined triggers and uploads them to a server for storage. It includes two core parts:
Snapshot Triggers: Make call, incoming ring, call answer, input trigger (intercom), output trigger (intercom), door unlock (door phone)
Image Upload: Supports HTTPS, HTTP, FTP, TFTP servers
Suitable for scenes that need to save event images, such as e-bike entering elevator monitoring.
Prepare 1 Bi30 video door phone + 1 BF600S video phone, connected to a switch with valid IP addresses
Prepare a configuration PC with server software installed, connected to the same LAN as devices
Take Bi30 video door phone as an example:
To use the snapshot function, you need to set up a server and configure the door phone. This guide uses Bi30 + WFTPD (FTP server) as an example.
Download WFTPD (no installation required).
Open software → click Security – User/Rights
Click New User → enter username (e.g., 123) → OK
Enter password (e.g., 123) → OK
Set FTP root directory (e.g., E:\temp\WFTPD) → paste into Home Directory
Log into the device WEB interface to set snapshot triggers and upload URL.
URL Format Example:ftp://123:123@172.18.8.254/
- ftp: protocol type
- 123:123: username:password
- 172.18.8.254: server IP
- /: save to root directory; use /snap/ for subfolder
Set Trigger Conditions (Door Phone):
Any enabled trigger will capture and upload an image (e.g., door unlock).
Snapshot File Naming: Event + Time stamp
If no images are saved on the server, check the following:
Network: Ensure the device can reach the server
Server Configuration: Verify username/password and write permission; test upload with other tools
Other Issues: Contact technical support
