Quick answer
Agent DVR can run on supported Raspberry Pi setups. Frigate and Scrypted require careful hardware guidance, and Scrypted does not recommend Raspberry Pi 4 for NVR use.
The decision that matters
Use a Raspberry Pi for modest restreaming or supported NVR workloads only after checking decode, storage and acceleration requirements. This page is written for makers and home users considering a small camera server. The key decision is: Camera count and codec load matter more than the board’s low purchase price; some NVR projects explicitly discourage underpowered models.
The right recommendation changes with the operating system, whether a server can stay online and where people actually watch the cameras.

How this guide evaluates software
Search results often place media players, mobile camera apps, self-hosted recorders and enterprise video-management systems in the same list. That is misleading because they own different parts of the workflow. This guide first identifies the operating role, then compares current official product documentation for platform support and the features relevant to that role.
Compatibility is evaluated by exact camera model and firmware, not brand name alone. RTSP controls a real-time media session; ONVIF can add discovery, profiles, events, PTZ and audio, but optional features still vary between conformant devices and clients. A successful camera discovery result therefore does not prove that every stream, codec or control will work.

Role-based shortlist
The products below are not ranked by the length of their feature lists. They are shortlisted because each represents a distinct, defensible role for this search.
| Product | Platforms | Best fit | Watch for |
|---|---|---|---|
| Agent DVR | Windows, macOS, Linux, Docker and Raspberry Pi | A self-hosted, cross-platform NVR with RTSP and ONVIF inputs, recording, motion tools and optional remote services. | Server deployment, storage and remote-access choices add operational work compared with a native local viewer. |
| Frigate | Linux or Docker, commonly with Home Assistant | A local NVR built around object detection, event retention, MQTT and RTSP restreaming for automation-heavy homes. | Hardware acceleration, detector selection and YAML configuration make it a poor fit for someone who only wants to open a camera feed. |
| Scrypted | Server, Docker and supported home platforms | A camera integration platform that can bridge local cameras to HomeKit, Google Home, Alexa and Home Assistant, with an optional NVR workflow. | The server, plugins and camera preparation steps are unnecessary if the goal is simply local live viewing. |
| FFmpeg / ffplay | Command-line environments on major desktop and server systems | A precise diagnostic and automation tool for RTSP transport, codecs, restreaming and stream inspection. | Command-line operation is powerful but less approachable and less camera-focused than a native viewer. |
Where SmartRTSP fits
Use SmartRTSP as the viewing endpoint and keep the Pi’s role narrow—such as an integration or restream service—when that produces a more reliable system.
SmartRTSP is promoted when the required job is direct, camera-focused viewing on supported Apple devices or Windows. It connects to compatible RTSP and ONVIF cameras, supports multi-camera viewing and keeps the normal local viewing path on the user’s devices. Android is currently offered as a closed beta, and the Windows app is now available from the Microsoft Store: https://apps.microsoft.com/store/detail/9NJWJKG6DK11
SmartRTSP
Use SmartRTSP as the viewing endpoint and keep the Pi’s role narrow—such as an integration or restream service—when that produces a more reliable system.
When another product is the better choice
Do not attach critical multi-camera retention to an SD card and hope for desktop-class endurance.
SmartRTSP is not presented as a universal replacement for an always-on recorder, Linux server or enterprise VMS. If the workflow requires continuous retention, evidence export, centralized permissions or server-side automation, keep or add software built for those duties.
Pilot checklist
Calculate total decode and record bitrate, then choose storage and cooling before installation.
- Inventory the exact camera model, firmware, RTSP path, ONVIF profile and main/substream codecs.
- Create a unique view-only camera account; do not reuse an administrator account in everyday viewer apps.
- Test the real device, camera count and network for at least one normal operating shift.
- Verify live video, audio, PTZ, reconnects and recording separately instead of treating “connected” as complete compatibility.
- For remote viewing, use a managed VPN. Do not forward RTSP port 554 or camera administration ports to the public internet.
- Record the rollback plan and keep a second stream test tool available during the pilot.
Security and privacy baseline
Put cameras on a separated network or VLAN where practical, change default credentials, apply supported firmware updates and synchronize time. Use the least-privilege camera account that still provides the required stream or control.
Local-first does not mean risk-free. Public port forwarding, abandoned firmware, shared passwords and unnecessary retention can undermine an otherwise private design. Document where live video, clips, thumbnails, credentials and backups travel.
