Why iPhone & Mac Users Choose SmartRTSP

Native iOS & macOS app

SmartRTSP is built specifically for iPhone, iPad, and Mac. It uses native system APIs — not a web browser wrapper — giving a fast, responsive experience with proper iOS notifications and background handling.

No server to maintain

iSpy requires a Windows PC to stay on and running as a server. SmartRTSP connects directly from your iPhone to the camera — no intermediate machine, no ports to forward, no uptime dependency.

On-device AI runs locally

Person, motion, face, and sound detection runs entirely on your iPhone or Mac using on-device AI. No footage leaves your device for analysis, and no third-party AI cloud service is involved.

5-minute setup

Install the app, tap Scan, and SmartRTSP finds your cameras automatically via ONVIF. Most users are viewing live cameras within 5 minutes — no server configuration, no firewall rules, no technical expertise required.

Why Some Users Prefer iSpy

iSpy is an excellent choice for users with specific needs that favor Windows-based server software:

  • Open source — full code transparency and ability to self-host and modify
  • Windows-centric workflows — users already managing Windows systems may prefer a Windows-native tool
  • Plugin ecosystem — iSpy has an extensive plugin system for custom integrations and automation
  • Long-running recording server — iSpy is designed to run 24/7 on a dedicated PC as a recording and archival server
  • Unlimited cameras — the free version imposes no camera count limit

Is iSpy Available on iPhone?

There is no native iSpy app for iPhone or iPad. iSpy is a Windows application only.

iSpy's commercial successor, Agent DVR, offers a web interface that can be accessed from an iPhone browser — but it is not a native iOS app. It runs in Safari or Chrome, does not support native push notifications, and requires a running Windows or Linux server to function.

SmartRTSP is the native iOS alternative. It connects directly to your cameras from your iPhone or iPad without requiring any server. All processing happens on the device — no PC needs to be running.

Frequently Asked Questions

Can I use both SmartRTSP and iSpy at the same time?
Yes. Both SmartRTSP and iSpy connect to the camera's RTSP stream independently. You can have SmartRTSP running on your iPhone and iSpy running on a Windows PC simultaneously, both viewing the same cameras. Most cameras support multiple simultaneous RTSP connections without any additional configuration.
iSpy vs SmartRTSP for Mac — which should I use?
SmartRTSP is the clear choice for Mac. It is a native Mac App Store app built specifically for macOS — it runs natively on both Apple Silicon and Intel Macs. iSpy is a Windows application only and has no native Mac version. Running iSpy on Mac would require a virtual machine or compatibility layer.
Is SmartRTSP open source like iSpy?
No, SmartRTSP is not open source. However, all video decoding and AI detection processing runs entirely on your device — no footage or data is transmitted to any external server. iSpy's original codebase is open source; its commercial successor Agent DVR is closed source with a subscription model for advanced cloud features.
Is iSpy free or paid?
The original open-source iSpy software is free. Agent DVR, the commercial version by the same developer, has a subscription fee for its cloud connectivity and remote access features. Local-only use of Agent DVR is available with a free tier but with some feature limitations.
