Current pedestrian detection solutions (cameras, radar) have severe performance limitations in harsh lighting conditions such as night, blinding sun. Additional thermal sensors can detect the heat of living beings in low-visibility conditions. Importantly, thermal sensors are not limited by the range of the car's headlights which increases the detection distance giving more time for the car to brake.
In the future, autonomous vehicles will have to navigate safely both day and night in all weather conditions regardless of the so-called level of automation. A new solution for detecting pedestrians using thermal sensors will be required from Level 2:
- Level 5 – full automation – no driver needed.
- Level 4 – high automation – at this level, the car's system is fully capable of monitoring the driving environment and operating all driving functions on routine routes and under certain conditions. The vehicle can warn the driver that it is approaching its operational limits, if, for example, there are environmental conditions that require human control, such as snowfall. If the driver does not react, the system will automatically secure the vehicle.
- Level 3 – conditional automation. Under certain conditions, the car can drive itself, such as on a highway.
- Level 2 – partial automation, i.e. a development of level 1, e.g. traffic jam driving assistant, automatic parking system.
- Level 1 – basic driver support system, e.g. active cruise control, lane keeping system. The electronics can gently change the vehicle's trajectory (e.g., bypassing an obstacle), as well as adjust speed (acceleration, braking). However, it can only do one of these things at a time. The car is still controlled by the driver.===
- Level 0 – no driving automation functions of any kind. Everything is in the hands of and under the control of the driver.
The objective of the EU-funded Heliaus (tHErmaL vIsion AUgmented awarenesS) project is to develop intelligent systems composed of thermal sensors that will detect long-wave infrared radiation (LWIR) for both monitoring passengers in the cabin and the car's surroundings. Lynred is currently developing a product, based on existing 12 µm technology, which could be fitted to cars launched between 2024 and 2025. However, the Heliaus project aims to develop a new generation of products based on 8.5 µm sensors for market introduction after 2027. The outcome of the Heliaus project will be a prototype camera integrating the sensors and optical technologies developed under the project. The Heliaus project can be used in other highly automated systems such as industry, robotics, IoT or health care.
TerrNet application – fast and intuitive programming of TERRA channel amplifiers.
The PA320TP R82513 and PA420T R82516 TERRA channel amplifier can be used standalone – as part of a multiswitch or headend system. TERRA amplifiers are dedicated to receive RF signals in difficult conditions. They will perform well in places where there are signals of varying levels, transmitted from one or several directions. Each of the 20 amplification paths is equipped with automatic gain control (AGC) and an ultra-selective SAW (Surface Acoustic Wave) filter. TERRA's PA320TP R82513 and PA420T R82516 channel amplifiers are digitally programmable using any mobile device equipped with Android or Windows PC (TERRnet app). The Control connector (micro USB socket) is used to connect the device to program the amplifier. When the amplifier is connected to the power supply, the green and red LEDs flash simultaneously to indicate its configuration.An exemplary diagram of a TV installation using the TERRA PA420T R82516 channel amplifier.
Fiber optic installation for cameras installed on poles.
Feeding a separate cable to each pole (mast, lantern), on which the cameras are to be installed, is the most universal and the least labor-consuming solution when it comes to attention welding and protection of optical fibers. However, this involves a greater amount of work when laying cables and the need to provide more space on the cable route.In this topology, the design of the cable itself, i.e. the method of securing the fibers in it, is of no great importance. It is, of course, to have all the parameters necessary for proper operation in the given environmental conditions and be adequately resistant to tearing when the cable is pulled into the ducting.
The choice of the star topology also allows you to save space on the pole itself – the fiber optic cable can be inserted directly into the box, in which devices including media converter, PoE switch, video converter, power supply etc., are installed. The fiber optic, of course has to be secured with a pigtail, and the connection (splice) itself should be secured on the splices box or a dedicated optical fiber box. Then the pigtail should be plugged into the fiber optic adapter, and the connection with the device responsible for signal conversion should be made using a patch cord. Do not plug the cable directly into the device! In the future, when performing any service or maintenance work, the installer will only risk damaging the patch cord, and not the cable, which would entail the need to splice the fiber again.
SIGNAL CCTV 210/230/145 mm sealed box is R90601 designed for mounting on a pole, mast or wall. Inside, there is a mounting plate which can be easily removed, and two DIN rails for easy installation of components such as switches, power supplies, media converters or mini fiber optic distribution frames. Additionally, the box has protective wires which can be connected to active devices.
The box can easily accommodate, among others, an industrial switch, power supply, main switch and mini distribution frame in the case of systems based on fiber optic cabling (if this is the case, we recommend the use of ODF-DIN L5312 mini distribution frame). All these elements can be mounted on DIN rails or aluminum mounting plate. Thanks to adequate number and size of cable gland holes, it is possible to lead in and out the cabling for: power supply, fiber optic cable, twisted pair, for connecting up to 4 surveillance cameras.
Connecting the DS-K1104MK reader to DS-K2604T controller using RS-485 bus.
With the DS-K2604T G75018 controller, you can control up to 4 single- or double-sided controlled passages. An RS-485 bus, dedicated for connecting readers, has been pulled directly from the main board onto a terminal block inside the controller's housing. The bus is marked on the terminal block as RS485+ (directly on the RS485A+ motherboard), RS485- (directly on the RS485A- motherboard) along with GND ground and +12V power supply. In order for the reader to be supported by the controller and to be assigned to a specific door, it must be properly connected to the controller and addressed using the dip switches on the back of the reader. The table below indicates which readers should be addressed depending on which door they are to serve, and the wiring diagram for the controller's terminal block.| DIP Switch | Access control point | Reader |
| 1000 0000 | Door 1 | Input reader 1 |

Fiber optic cable in B2ca flammability class.
From July 1, 2017 in the EU, all installation cables in buildings are considered to be construction products subject to applicable regulations. The CPR Directive requires manufacturers to develop and make available the Declaration of Performance (DoP), as well as to mark products covered by the relevant CE mark. The EN50575 specifies the requirements for: performance in fire conditions, test and evaluation methods for power, control and telecommunications cables used in buildings with a specific fire resistance class. With the introduction of pan-European fire response classes, designers and architects have clear regulations specifying the rules for selecting cables. To achieve increased fire safety levels, the regulations recommend the use of B2CA cables in special buildings that must meet very tight safety requirements (e.g. in hospitals, nurseries, high-rise buildings, office buildings and nursing homes).
Prysmian IC-ROUND 02J7A2 L7002_1000 fiber optic cable meets the legally required non-flammability class standards. It has a LSOH sheath (halogen-free insulation). In the event of a fire, the cable does not spread flame, smoke emission is very low and the released gases are not corrosive. 2 fibers in G.657A2 stanard make it ideal for use in residential construction industry.

Improving the coverage of cell phone networks at home. As a result of high attenuation of walls and windows, the cell phone signal is often too weak inside the home to make calls comfortably over the phone.
The solution to the problem can be the GDW-505 A6777 device which is used to amplify the GSM, DCS, 3G, LTE signal and bring it indoors. The repeater has to be connected with an external antenna, directed towards the base station of the operator, and to an internal antenna which will distribute the amplified signal.>>>more
