Operation instructions for the Intrasonic Technology V500 IP Video Monitor — the indoor unit of a video door intercom system.
Operation instructions for the Intrasonic Technology V500 IP Video Monitor — a video door intercom (indoor monitor) supporting outdoor doorbell cameras, network/WiFi connectivity, mobile app control, and remote web browser access.
The V500 IP Video Monitor is the indoor unit of a video intercom system. It works with one or two outdoor doorbell cameras (Door1/Door2), supports internal communication between multiple indoor units, and can be accessed remotely via the "IST VIEW" mobile app or a web browser over the local network or WAN.
The device uses a single three-in-one control button ("O") for all menu navigation:
| Menu Item | Function |
|---|---|
| Language | Changes the on-screen menu/display language. |
| Time | Switches date format (YY-MM-DD, MM-DD-YY, DD-MM-YY) and sets system date/time. "Time display" options: 1min, 3min, 5min, 10min, or Off — controls how long the clock shows on-screen in standby. |
| Information | Displays software version and release date. |
| Network | Enter/exit AP mode manually, restore default settings, restore default password (default: 888888). |
| Password | Sets the administrator password used for web browser or IST VIEW app login (default: 888888). |
| Reboot | Restarts the device (confirmation prompt shown). |
Devices with WiFi capability can operate wirelessly. If a network cable is connected, WiFi parameters can be set via IE browser (Network → WiFi settings). Without a wired cable, use a wireless router plus a smartphone/tablet (iOS or Android) and configure WiFi via the "IST VIEW" app and AP mode (see below).
The V500 supports remote viewing via web browser over LAN or WAN, using either IP address or domain name. Recommended browsers: Internet Explorer 6–11, Mozilla Firefox, or Google Chrome, on Windows XP/7/8. Run Internet Explorer as Administrator on Windows 7/8/8.1 (not required on XP). Disable the firewall and any active antivirus software before configuring remote access.
http://XXX.XXX.XXX.XXX) — found via the "IST VIEW" app's LAN Search, or use a public IP if the device is on the WAN.Requires at least two indoor units connected. From standby mode, press the intercom button — a continuous ring tone sounds on the other unit(s). Press the talk button on any indoor unit to start a conversation between units. Press "Hang Up" to end and return to standby.
If a visitor presses the outdoor doorbell call button while units are in internal communication, internal communication is switched off automatically — the visitor's image appears with continuous ringing, and pressing the talk button reactivates conversation with the visitor.
While talking to an outdoor camera visitor, press the transfer button to activate call transfer. The original conversation unit returns to standby, while the target extension sounds a continuous ring tone and displays the visitor's video. During the call, the electric door lock can be opened, and the call can end with the system returning to standby automatically.
