Overview

The HIKMICRO Mini2 thermal camera for Android is a compact and portable thermal imaging solution designed to turn a compatible USB-C Android smartphone or tablet into a powerful thermal inspection tool. With a 256 x 192 infrared resolution, 25 Hz image frequency and a highly sensitive VOx detector with NETD below 40 mK, the Mini2 produces clear and detailed thermal images for everyday inspections, maintenance and troubleshooting.

Its small 42 x 22.5 x 11.2 mm design and approximately 20 g weight make it easy to carry in a pocket or tool bag. The battery-free design draws power directly from the connected mobile device, while the plug-and-play connection allows the camera to be ready for use within seconds.

Description

The HIKMICRO Mini2 is a USB-C thermal imaging camera designed for Android smartphones and tablets. It combines a high-resolution infrared detector with a wide 50 degree field of view, focus-free operation and practical temperature measurement tools. This makes it useful for identifying heat loss, water leaks, insulation problems, air infiltration, electrical issues and other temperature differences that may not be visible to the naked eye.

The 25 Hz image frequency provides smooth thermal video when scanning surfaces or moving around an inspection area. Temperature measurements can be taken using the centre spot, hot spot, cold spot, three custom spots and three measurement areas, while adjustable emissivity, distance and temperature range settings help improve readings across different surfaces.

The Mini2 is also designed for convenient field use. It has an IP40-rated aluminium alloy housing and can withstand drop tests from up to 1 metre. Since it has no internal battery, there is no separate charging routine - simply connect it to a compatible Android device and use the HIKMICRO Viewer app.

Features

Clear Thermal Imaging for Android
The 256 x 192 infrared resolution provides 49,152 thermal pixels for detailed image capture. Combined with a NETD of less than 40 mK and a 12 um detector pitch, the Mini2 can reveal subtle temperature differences during inspections.

The 50 degree x 37.2 degree field of view is particularly useful when scanning larger surfaces such as walls, floors, ceilings and building facades. Its 3.5 mm F1.0 lens uses focus-free operation with a minimum focus distance of 0.2 m.

Key imaging details include:

• IR resolution: 256 x 192 pixels
• NETD: Less than 40 mK at 25 degrees C
• Image frequency: 25 Hz
• Spectral range: 7.5 to 14 um
• Focal length: 3.5 mm
• F-number: F1.0
• Field of view: 50 degrees x 37.2 degrees
• Focus mode: Focus Free
• Minimum focus distance: 0.2 m

Temperature Measurement and Analysis
The HIKMICRO Mini2 provides practical temperature measurement functions through the HIKMICRO Viewer app. It can measure object temperatures across a wide range and provides visual and audio alerts when a preset high-temperature threshold is exceeded.

Temperature measurement tools include:

• Object temperature range: -20 degrees C to 400 degrees C
• Accuracy: Up to plus or minus 2 degrees C or plus or minus 2 percent under specified conditions
• Centre spot, hot spot and cold spot measurement
• Three user-definable measurement spots
• Three user-definable rectangular measurement areas
• Auto and manual level and span modes
• High-temperature alarm

The stated accuracy applies under the manufacturer's specified ambient and object temperature conditions. Actual readings can vary depending on the surface material, emissivity, distance and operating environment.

HIKMICRO Viewer App
The free HIKMICRO Viewer app for Android provides the controls and analysis functions needed to get more from the Mini2 . Users can view thermal images, adjust measurement settings and select from a range of colour palettes to make temperature differences easier to identify.

The app supports 15 colour palette options, including White Hot, Black Hot, Rainbow, Ironbow, Sepia, Color, Ice Fire, Rain, Red Hot, Green Hot, Dark Blue and Combined.

Professional settings such as emissivity, distance and temperature range can be adjusted to help achieve more appropriate thermal readings for different inspection applications.

Compact, Battery-Free Design
At approximately 20 g, the Mini2 is small enough to remain in a tool bag, pocket or equipment case without adding significant weight. Its dimensions are just 42 x 22.5 x 11.2 mm.

The camera is powered through the connected Android device, eliminating the need for an internal battery or dedicated charger. The 360 mW power consumption is designed to minimise the impact on the mobile device's battery.

For difficult inspection locations, the included 40 cm extension cord allows the thermal camera to be positioned away from the smartphone or tablet. An 18 mm extended connector is also supplied for use with mobile devices fitted with protective cases.

Practical Inspection Applications
The wide-angle thermal camera can be used for a variety of maintenance, building and troubleshooting tasks. It can help identify temperature differences associated with:

• Water leaks and damp areas
• Poor insulation and heat loss
• Air infiltration
• Electrical and equipment hot spots
• Building maintenance issues
• Heating and cooling system checks
• General thermal inspection and troubleshooting

Its compact design also makes it suitable for technicians, maintenance personnel, installers, engineers, DIY users and anyone who needs a portable thermal imaging camera for Android.

Durability and Everyday Portability
The Mini2 uses an aluminium alloy housing with an IP40 protection rating and is tested for drops from up to 1 metre. It operates in temperatures from -10 degrees C to 50 degrees C and can be stored between -20 degrees C and 60 degrees C.

The combination of rugged construction, compact dimensions and battery-free operation makes the Mini2 convenient for regular field inspections where carrying a larger standalone thermal camera is impractical.
