Guide MobIR 3.0 ES1 – Compact Thermal Imaging for Your Smartphone
The Guide MobIR 3.0 ES1 is a compact smartphone thermal camera designed to make thermal inspection quick, simple and highly portable. From home inspections and HVAC diagnostics to electrical troubleshooting, equipment maintenance and outdoor applications, the ES1 turns a compatible smartphone into a capable mobile thermal imaging tool.
Thanks to its USB-C plug-and-play connection, the MobIR 3.0 ES1 supports both iOS and Android smartphones, eliminating the need for a separate display or bulky handheld thermal camera.

120×90 Thermal Resolution with ApexVision Technology
The ES1 features a 120×90 infrared detector enhanced by Guide's new-generation ApexVision imaging technology. Real-time Super Resolution processing increases the displayed thermal image resolution up to 480×360, helping reveal finer thermal details and making temperature differences easier to identify.
With a thermal sensitivity of ≤15 mK NETD, the camera can distinguish subtle temperature variations for clearer and more informative thermal images.
Professional Temperature Measurement

The MobIR 3.0 ES1 offers a wide -20°C to 550°C temperature measurement range with accuracy of up to ±2°C, making it suitable for a broad range of applications, including:
- electrical inspection and troubleshooting,
- HVAC and heating system diagnostics,
- building and insulation inspections,
- equipment and machinery maintenance,
- automotive diagnostics,
- electronic component inspection,
- general home thermal monitoring.
Wide 56°×42° Field of View
The wide 56°×42° field of view allows larger areas to be inspected at once. This reduces the need for constant device movement and helps users locate temperature anomalies more efficiently.
Plug and Play in Seconds
Simply connect the MobIR ES1 to your smartphone and thermal inspection can begin in approximately 5 seconds. There is no complicated setup and no lengthy start-up procedure.
In addition to the IR thermal image, a PIP mode using the smartphone camera is available, helping users relate thermal information to the inspected object or area.

FocusIR App and AI Assistant
The professional FocusIR app transforms your smartphone into a portable thermal imaging workstation, providing convenient access to thermal images and inspection functions directly from the phone.
A built-in multilingual AI assistant provides step-by-step guidance from initial setup to more advanced operation, making thermal imaging easier to learn even for first-time users.
