    Setup Overview

    1. Collect information — Get the Wi-Fi SSID/password from the user, and peel/record the Device ID (DID) QR code from the IVPC-DS mounting plate.
    2. Set up for pairing — Prepare both devices.
    3. Pair the IVPC-DS — to the IVPC-MS or the OPTEX Vision App.
    4. Choose the location — verify the install site meets performance needs.
    5. Mount the IVPC-DS — install on site (battery or wired).
    6. Confirm operation — final test and hand off documentation to the end user.

    Default Passwords

    • Device password (default 123456): Used when pairing the IVPC-DS with the IVPC-MS or Vision App. Must be changed at first pairing.
    • Admin password (default 123456): Used when changing settings. Must be changed after the first settings change.

    iOS note: Pairing over Wi-Fi Direct may require SSID "RVDP-xxxxxxxx" with password "12345678".

    Pairing Procedure — IVPC-DS

    1. Loosen the lock screw, remove the mounting plate, and remove the front cover (pry with a flat driver).
    2. Power on by pressing the power button — confirm the LED flashes blue & white (pairing mode). If not in pairing mode, hold the factory reset button.
    3. Replace the front cover and rubber bushing, then push to secure.

    Factory reset: Press and hold the reset button (under the rubber plug) for 5 seconds until the white & blue LED starts blinking.

    Pairing Procedure — IVPC-MS

    1. Plug into an AC outlet via the Micro USB port (do not use any adapter other than the one included).
    2. Press the power button to turn on — confirm the LED lights.
    3. Wait for the OPTEX Vision App startup screen to display.

    To use a smartphone/tablet instead of the IVPC-MS, download the free "OPTEX Vision" app from the App Store or Google Play (internet connection required).

    Choosing the Mounting Location

    • Recommended mounting height: 1,500mm (5'). A height of 1,000mm (3'4") requires review.
    • Camera view angle: 135° horizontal / 75° vertical.
    • Avoid backgrounds with bright/changing lighting, such as direct sunlight.
    • Confirm Wi-Fi signal before mounting: hold the IVPC-DS at the intended spot, press the doorbell, and verify the IVPC-MS/app responds confirming Wi-Fi communication with the router. Signal indicator levels: Excellent / Good / Fair.

    Mounting — Battery Operation

    1. Fix the mounting plate, attach the main unit, slide down to lock, and tighten the lock screw.
    2. Charge via the Micro USB port using a 5V DC / 1A (or greater) USB power supply. Full charge takes ~10 hours.
    3. Only recharge when ambient temperature is +10°C to +40°C (+50°F to +104°F).

    Mounting — Wired Operation (New Installation)

    Power requirement: 10 to 24V AC/DC. Polarity is not a concern.

    1. Turn off power, fix the mounting plate, remove the back cover.
    2. Wire the power cables (any polarity).
    3. Replace the back cover (protects against water intrusion — make sure nothing interferes with the seal).
    4. Assemble the main unit, tighten the lock screw, turn power back on.

    Note: if the external power source is off, the IVPC-DS runs on its internal battery — it may shut down unexpectedly if power isn't restored before the battery depletes.

    Retrofit Wiring (Replacing an Existing Door Chime)

    1. Turn off power and disconnect all wires from the existing chime.
    2. Remove the existing doorbell button (it will not be reused).
    3. Mount the IVPC-DS in its place per the wired-operation steps above.
    4. Connect the existing power source (10-24V AC/DC) to the IVPC-DS, using the included bypass cable if needed.
    5. Turn the IVPC-DS power back on.

    Final Confirmation

    1. Push the doorbell button on the IVPC-DS and confirm audio/video appears on the IVPC-MS or app.
    2. Review the settings section of the full user manual to customize as needed.
    3. Hand this guide and the user manual to the end user for their records.

    Troubleshooting

    Issue Solution
    Registration not completed Hold the factory reset button on the IVPC-DS to re-enter Wi-Fi registration mode and retry. If device isn't in the list, retry registration and manually enter the Device ID.
    LED changes from blue/white to no light or solid white Poor Wi-Fi communication — move the router closer to the IVPC-DS, or add the optional IVPC-ANT external antenna.
    LED blinks blue/white/off slowly Wi-Fi router disconnected — a Wi-Fi range extender may help expand coverage.
    Chime doesn't sound, LED doesn't light Check power supply. Battery: charge (~10 hrs at 5V/1A). Wired: verify 10-24V AC/DC at the terminals.
    Audio is interrupted Improve Wi-Fi signal (move router closer, add external antenna) or raise volume on the IVPC-MS/app if signal is already good.
    Picture is distorted Improve Wi-Fi signal, and move away from 2.4GHz interference sources (microwaves, baby monitors).
