Video: IR-DLD-TS – Product

Video transcript

A fixed camera with two images, thermal to measure, visible to recognise. What it watches, how it measures and alarms, and how it joins the control system. A thermal image tells you that something is hot. On its own, it rarely tells you which device it is, and the person sent to repair it needs that answer. And at night, an ordinary camera sees nothing. This camera puts both pictures side by side, all day and all night, without anyone standing there.

In one housing, a thermal detector of up to 640 × 512, a visible camera of 1920 × 1080, a near-infrared light that reaches 30 metres, and an accuracy of 2 degrees or 2% of the reading. On the front, the thermal lens, the visible camera beside it, and below them the lamp that works as infrared fill light and as warning light. A sun shield covers the top, a sun shield covers the top, and the bracket lets the head tilt from 0 to 90 degrees. There are three thermal resolutions, 640 × 512 and 384 × 288 with a sensitivity

of 0.04 of a degree and 256 × 192 with 0.05. Each comes with two lenses, a wide one around 50 degrees and a narrower one for targets further away. two channels can be shown as a picture-in-picture or fused into one image, with the fusion distance adjusted to the scene. Temperatures can also be overlaid on the visible picture. The visible image says which breaker, which terminal. The thermal one says how hot. measurement runs in real-time on up to 10 movable points, 10 areas and 3 lines,

each with its maximum, minimum and average, and areas can be drawn with irregular outlines to follow the shape of a component. Two ranges cover from minus 20 to 180 degrees and up to 650. A good number needs three settings. The emissivity, from 0.01 to 1, tells the camera how much the surface really radiates. The distance correction compensates for the air in between, and the linear correction trims the reading against a reference.

The detector corrects itself at power on and again at intervals during operation. thermal channel does not need light. It images in total darkness and through mist. The visible channel gets help from the near-infrared fill light, which keeps it useful up to 30 meters, so the camera can still show what it is looking at when the sight is dark. Alarms are raised by high or low temperature rules, by the hardware input, or by image analysis such as motion detection.

On sight, the camera can switch its warning light and buzzer and its alarm output. Upstream, the readings and the alarm reach the control system. For integration, it behaves like an IP camera and like a sensor at the same time. Temperatures go to PLC and SCADA systems over Modbus, RTU on the RS-485 port or TCP on the network. Video goes to management platforms through ONVIF, RTSP or GB28181. And one PoE cable carries power and data. It is built for permanent outdoor service, an aluminum housing sealed to IP66

with lightning and surge protection working from minus 20 to 50 degrees. It weighs under a kilogram and consumes at most 5 watts. Typical places, substation equipment and switchgear washed around the clock, perimeters and processes where the visible image confirms what is happening, and warehouses and outdoor installations where an early temperature rise is the first sign of a fire. Next to the IR DLD-T, which is thermal only. This camera adds the visible channel, the night fill light,

fusion and picture in picture, and the warning light and buzzer. Thermal monitoring from Amperis.
