The four kinds of camera app
| Kind | Good at | Weak at | Examples |
|---|---|---|---|
| Manufacturer app | Setup, firmware, alerts, playback, cloud access without a VPN | Other brands; needs an account; remote video often relayed | Hik-Connect, DMSS, Reolink, Tapo |
| Universal viewer | Mixed brands in one app, direct local video, no account | Alerts and 24/7 recording (varies by app) | IP Camera Viewer & Monitor |
| NVR or VMS software | Continuous recording, detection, timelines, many cameras | Needs an always-on computer or recorder and setup time | Blue Iris, Synology Surveillance Station, Frigate |
| Desktop player | Testing an address in seconds | No camera list, layouts or controls | VLC |
Choose by what you need to do
- Watch live, cameras from several brands: a universal viewer on your phone and tablet.
- Record everything, around the clock: an NVR or recording software, with a viewer or its own app for live view.
- Get a notification when someone walks up: the camera's own app or your NVR's app, which run the detection.
- Watch away from home without a VPN: the manufacturer's cloud. With a VPN, any local viewer works from anywhere.
- Keep video off third-party servers: local viewing plus a VPN, with cloud features turned off in the camera.
Phones, tablets and computers
IP Camera Viewer & Monitor runs on iPhone and iPad (iOS and iPadOS 17 or later) and on Android, with the same core features and the same free tier of one camera. The Android version also retries a stream over UDP when TCP fails, which helps with some older cameras. On a computer, VLC is the tool for testing an address, and NVR software is the tool for recording.
On iPad, groups of up to nine cameras make an always-on wall display; the iPad guide covers the setup. iPhone-specific advice is in the iPhone guide.
Common mistakes when choosing
- Buying cloud-only cameras, then looking for a different app. Ring, Nest, Arlo and Blink cannot be opened by anything but their own apps. Check for RTSP or ONVIF before you buy.
- Judging an app on the main stream over mobile data. A 4K stream through a VPN on 4G will stall in any app. Use the sub-stream away from home.
- Forgetting H.265. Many newer cameras default to it. An app without hardware H.265 decoding shows a black tile or a slideshow.
- Forwarding ports to reach cameras remotely. It exposes the camera to the whole internet. A VPN does the same job safely.
- Expecting a viewer to record. Viewers are for watching. Continuous recording belongs on an SD card, an NVR or recording software.
Frequently asked questions
What is the best free IP camera app?
It depends what you need free. Manufacturer apps are free and often sell cloud storage. VLC is free and plays any RTSP address but has no camera list. IP Camera Viewer & Monitor is free for one camera, with Pro for more cameras and features.
Do I need an NVR to use an IP camera app?
No. Viewers connect to each camera directly. An NVR only matters if you want continuous recording; when you have one, a viewer can also open the NVR's channels.
Can one app show cameras from different brands?
Yes, as long as every camera supports RTSP or ONVIF. That is the main reason to use a universal viewer instead of several manufacturer apps.
Is it safe to view IP cameras over the internet?
Through a VPN to your home network, yes. Forwarding camera ports on your router is not: it exposes the camera's login to anyone scanning the internet.
Which app works with the most cameras?
Any app built on the open standards. RTSP and ONVIF cover most wired and many Wi-Fi cameras, so an app that supports both, with H.265, works with far more models than any one manufacturer's app.
