Tapo.NET 1.0.0

Tapo.NET

A .NET library (netstandard2.1) for TP-Link Tapo IP cameras. Speaks the camera's local control channel and media-stream protocol directly — no ffmpeg in the hot path, no cloud round-trip — so you can list and pull SD recordings as fast as the LAN allows. Tested against the TAPO C260 but the protocol is shared across the IPC line (C100/C110/C200/C210/C220/C260 …). Runs on .NET 6/7/8/9, .NET Core 3.0+, Mono and any other runtime that implements .NET Standard 2.1.

Features

• Native fast video download — pulls SD recordings as raw MPEG-TS straight to disk over the camera's 8800/tcp media stream. The camera's X-Data-Window-Size back-pressure knob is pumped directly and byte-aligned TS packets are written without any transcoding, so a 1-minute clip lands in seconds, not in real time.
• Optional time-sliced parallel downloads — split one recording across N concurrent media sessions and let the camera saturate the link.
• Local login — both the legacy hashed=true flow and the modern encrypt_type=3 (securePassthrough) handshake. MD5/SHA-256 password digest is auto-detected.
• Device commands — basic info, time, LED, lens-mask (privacy mode), motion detection, SD-card status, reboot — and an escape hatch (Methods) for any Tapo API method the typed clients don't cover.
• Snapshots — pull a single JPEG keyframe over the media stream without spinning up RTSP.
• Pluggable architecture — every layer (IControlChannel, IMediaSession, IVideoDownloader, IRecordingsClient, IDeviceClient, ISnapshotClient) sits behind an interface, so callers can swap in fakes for tests.

Installation

Via .NET CLI:

dotnet add package Tapo.NET

Via PackageReference:

<ItemGroup>
  <PackageReference Include="Tapo.NET" Version="x.y.z" />
  
</ItemGroup>

Quick start

Login to the camera, list yesterday's recordings, and download all of them as MPEG-TS files:

using Tapo;
using Tapo.Download;

await using var camera = new TapoCamera(new TapoCameraOptions
{
    Host = "192.168.1.50",
    Username = "admin",
    Password = "your-camera-password",
    CloudPassword = "your-camera-password", // usually the same value
    DefaultWindowSize = 256,
});

await camera.ConnectAsync();

var info = await camera.Device.GetBasicInfoAsync();
Console.WriteLine($"Connected to {info.FriendlyName} ({info.DeviceModel}), fw {info.FirmwareVersion}");

var date = DateTime.Today.AddDays(-1);
var recordings = await camera.Recordings.GetRecordingsAsync(date);

var downloader = camera.CreateDownloader(new VideoDownloaderOptions
{
    WindowSize       = 256,
    ParallelSessions = 2,    // try 1 if the link is flaky
});

foreach (var rec in recordings)
{
    using var fs = File.Create($"{rec.StartTimeUnix}-{rec.EndTimeUnix}.ts");
    await downloader.DownloadAsync(
        new VideoDownloadRequest(rec.StartTimeUnix, rec.EndTimeUnix),
        fs);
}

The downloader writes raw MPEG-TS. Wrap it in MP4 once with ffmpeg -i input.ts -c copy output.mp4 if you need a more portable container — the copy is essentially instantaneous because no transcoding is involved.

Snapshot

var snapshotClient = camera.CreateSnapshotClient();
var jpeg = await snapshotClient.CaptureAsync();
await File.WriteAllBytesAsync("now.jpg", jpeg);

Device commands

// Toggle the front status LED
await camera.Device.SetLedEnabledAsync(false);

// Lens mask (privacy mode)
var privacyOn = await camera.Device.GetPrivacyModeAsync();
await camera.Device.SetPrivacyModeAsync(true);

// Motion detection — read state, raise sensitivity to 80
var motion = await camera.Device.GetMotionDetectionAsync();
await camera.Device.SetMotionDetectionAsync(enabled: true, sensitivity: 80);

// SD card health and free space
var sd = await camera.Device.GetSdCardStatusAsync();
Console.WriteLine($"SD: {sd.FreeSpaceMegabytes}/{sd.TotalSpaceMegabytes} MB free");

// Reboot
await camera.Device.RebootAsync();

Calling raw Tapo methods

The typed Device client covers the common surface; for anything else, use the underlying invoker directly:

using var doc = await camera.Methods.InvokeAsync(
    "getOsd",
    new { OSD = new { name = new[] { "logo", "date", "week", "font" } } });

Console.WriteLine(doc.RootElement);

API surface

Top-level facade:

• Task ConnectAsync(...) — performs login.
• IRecordingsClient Recordings — recording listing/search.
• IDeviceClient Device — basic info, time, LED, privacy, motion detection, SD card, reboot.
• IVideoDownloader CreateDownloader(...) — fast SD downloads.
• ISnapshotClient CreateSnapshotClient() — JPEG capture.
• TapoMethodInvoker Methods — generic Tapo API calls.
• IControlChannel ControlChannel — diagnostic access to the wire layer.

Throughput knobs live on VideoDownloaderOptions:

Sample console application

A small example lives in src/Tapo.ConsoleTest:

1. Create a secrets.json next to Program.cs (gitignored):

   {
     "host": "192.168.1.50",
     "username": "admin",
     "password": "your-camera-password",
     "cloudPassword": "your-camera-password",
     "controlPort": 443,
     "streamPort": 8800,
     "windowSize": 256,
     "parallelSessions": 2
   }
   

2. Build and run:

   cd src/Tapo.ConsoleTest
   dotnet run -- 20251109     # download recordings of 2025-11-09
   

   With no arguments the sample downloads recordings of the current day into %TEMP%/Tapo.NET.Downloads.

Live integration tests

The repository includes live integration tests in src/Tapo.Tests. They exercise:

• Local login (legacy hashed=true and modern encrypt_type=3).
• getDeviceInfo, getClockStatus, recordings listing.
• LED on/off and lens-mask toggle (with state restoration).
• Motion-detection state read.
• getSdCardStatus (gracefully handles the "no SD card" error).
• JPEG snapshot capture (when privacy mode is off).
• Single-session and time-sliced parallel downloads (compares wall-clock duration of both modes for a recording of 30 s+).

Tests load secrets.json from the test output directory. Drop a copy next to src/Tapo.Tests/Tapo.Tests.csproj (or reuse the one next to the console-test project) and the test csproj will copy it to the test output on build. Tests skip cleanly with a console note when the file is missing or the camera is not reachable, so CI without a camera stays green.

dotnet test src/Tapo.Tests/Tapo.Tests.csproj

Downloaded artefacts go to %TEMP%/Tapo.NET.Tests.Downloads.
