Video: IR-DLD-TS – Technical guide

Video transcript

How the IR-DLD-TS is mounted, how its cable tail is wired, how it is found on the network and configured, and how it hands its data to the control system. First, the rules from the manual. Installation is for qualified installers with lightning protection on site. Never aim the lens at the sun or a laser, even switched off. The thermal sensor can be damaged for good. Do not touch the lens and check the power connection before switching on.

camera is 278 mm long and weighs under a kilogram. The bracket base is 87 mm across, with three holes of 4.2, and the head tilts from 0 to 90 degrees. The lens is athermalized and fixed. Once aimed, there is nothing to refocus. Everything enters through the cable tail. The round plug is the 12 V DC input. The four-way terminal is the alarm.

One and two are the input, three and four the output. The two-way terminal is RS-485, our plus and our minus. And the sealed RJ45 carries the network and the power when PoE is used. is a complete installation. The network goes first. The RJ45 to a PoE switch, which powers the camera and links it to the video platform and descata. Then the alarm input, from an external contact and the alarm output to a warning light or a relay.

Then the RS-485 pair to a PLC. The 12 V DC. The 12 V supply is needed only where there is no PoE. The power budget is small. With PoE, one cable does everything. Without it, a 12 V DC supply. Depending on the version, the camera draws at most 5 watts, or 3, and the network port is RJ45. The first connection follows a fixed order.

The camera leaves the factory with a default address, given in the manual. Put the computer on the same network segment, find the camera with the IP search tool, and give it its own address and gateway. Then log in from a browser, create your own user, and change the default password. Access is protected by HTTPS, User Categories, IP Filtering, and Access Log, and 802.1x. The address can also be changed from the browser, under Configuration, Network, TCP/IP, the IP address, the mask and the gateway, or DHCP.

The same menu holds FTP, Email, 802.1x, ONVIF, and GB28181. The web interface has four tabs, Live View, Playback, Configuration, and Alarm. In Live View, the side menu reaches the device setup, with palette, correction, and fill light, the image fusion, and the point, area, and line measurements. measurement takes an emissivity. The manual lists common values, around 0.95 for concrete, rubber, and brick, 0.93 for paint, 0.91 for a circuit board. Bare metal is far lower and reflective,

so paint or tape the spot, if it must be measured accurately. Alarm tab sets each alarm type, temperature measurement, the hardware input, motion detection, grayscale, and abnormal events. Each one can be linked to the alarm output, to the warning light, and to the buzzer. Test every link on site before handing the installation over. Upstream, there are two paths. Temperatures go to the PLC or SCADA by Modbus, RTU over RS-485, or TCP over the network.

Video goes to the management platform by ONVIF, RTSP, or GB28181. In a video management platform, the camera is added as one device with two channels. Search the local network, enable the device, and give it a name. Choose the Infrared Plus Visible mode, enter its address and its user, and enable the visible camera on the same address. Video and snapshots can be recorded on the camera itself, with 12 GB of built-in storage, on a TF card, or on network storage. Playback searches by time, and lets you download the clips and pictures.

Main and sub-streams feed the platform without overloading the network. Day-to-day, there is little to do. The detector corrects itself at power-on and at intervals, and a manual correction is available. Keep the lens clean without touching it. Never let it face the sun, and if the camera misbehaves, call the supplier rather than opening it. Thermal monitoring, from Amperis.
