Thermogram
Fixed thermal cameras and continuous monitoring
Compare fixed radiometric cameras by resolution, optics, ranges, interfaces and integration. A selection guide without an artificial ranking.

Plan an installation
These devices continuously monitor an asset or process. They are not selected like handheld cameras. This is a documentary comparison, with no performance order or new score; it does not certify industrial integration.
- Specify measurable area and the lens at the real distance, not just pixel count.
- Verify standalone versus PC operation, software licences and SDK, protocols, alarms and network-failure behaviour.
- Budget for housing, cooling, air purge, cables, power, converters and integration.
- Isolate the camera network, control access and avoid Internet-exposed streams.
- A thermal camera alone does not replace a regulated fire-detection system.
