About Terabee IND-Thermal-90

The Terabee IND-Thermal-90 thermal camera offers 32 x 32 pixel resolution thermal measurement. The rugged IP65 enclosure ensures dust-proof and water-resistant operation, while the camera’s compact form-factor (75 g) allows installation in places not possible with larger and heavier cameras. The camera embeds three Applications which can be optionally activated to raise alarms based on the comparison of the temperature with user-selected temperature thresholds.

It takes as little as four seconds to set up a switching threshold for temperature. Three multi-color LEDs provide a visual confirmation of temperature threshold breach, camera power and live data transfer, making set-up easy and intuitive.

Operating indicators

Onboard multi-color LEDs provide a visual confirmation of temperature threshold breach, camera power and connection status. Figure 6 and the corresponding Table 3 describe the connector location, and operating indicators. 

Camera coordinate system

The IND-Thermal-90 coordinate system is defined in Figure 7. The camera is always vertically mounted (M12 connector on the base), as per picture. The z-axis is to be considered as the distance from the target. Terabee IND-Thermal-90 is a passive optical temperature measurement camera that uses thermopile principle. The camera features a 90 degree Field of View, which corresponds to a detection area of 2 m × 2 m (spot diameter in reception) at 1 m range; 6 m x 6 m (spot diameter) at 3 m range, and scales linearly with distance, i.e. as 2 × z in Figure 7. E.g. if one considers the observer to be directed from the target to the camera as per Figure 8 - left, a typical resulting heatmap is shown in Figure 8 - right. Color-code is temperature [°C] from cold to hot (black → red → orange → yellow → white).

Figure 8. Typical views in color-code pictures in the manual: left- observer direction from target to camera; right - resulting heatmap (considering the registers mapping as shown in Section 7, Figure 15). Note that, given the choice of the observer, x axis direction is inverted in left and right Figures

Connectivity to RS485 bus

Figure 9. Connection of multiple IND-Thermal-90 cameras on RS485 network. External 120 Ohm termination resistors have to be added for signal stability at the beginning and end of the transmission line.

The RS485 interface is a half-duplex connection with the following default parameters:

❏ Baud rate : 19200

❏ Data bits : 8

❏ Stop bits : 1

❏ Parity : Even

On top of that, a Modbus RTU protocol is in place to handle the data transfer. Detailed information about the Communication registers are in Section 7. This is a master-slave type of protocol, ideal for RS485 data communications. This protocol supports up to 247 devices on the bus. The Terabee IND-Thermal-90 operates as a slave device.
