AI that can see through walls.
Researchers at MIT have presented a new approach to reconstructing objects hidden behind obstacles that combines analysis of wireless signals with generative artificial intelligence models. They use millimetre waves, capable of penetrating materials such as cardboard, plastic and drywall, and then analyse their reflections from invisible objects. The radio waves reflect off smooth surfaces at a well-defined angle, just as light reflects off a mirror. In practice, this means that the sensor only receives a return signal from parts of the object that are perpendicular to the transmitter, leaving the sides and underside of the object completely invisible to traditional signal analysis systems. The new approach solves this problem by using a generative model that fills in the missing fragments based on a partial reconstruction obtained from the measurements.
To solve the problem of incomplete data, the researchers developed the Wave-Former system, which combines the physics of wave propagation with advanced generative models. Rather than attempting to directly map an object from sparse reflection points, the system generates a set of potential surfaces and then uses a neural network to 'touch up' the missing parts of the 3D geometry. A key challenge was the preparation of the training data, as sufficiently large datasets do not exist. In response, the researchers created a synthetic dataset by adapting existing datasets from the field of computer vision and mapping the wave reflection properties and associated noise into them. This allowed a generative model to be taught to interpret the signals and reconstruct realistic shapes.
On the same principle, a system for reconstructing entire indoor scenes was also developed. In this case, multiple wave reflections from moving people are used, which generate complex signals containing information about the structure of the room. Generative models interpret this data and fill in the missing elements, allowing the layout of the space to be reconstructed using a single stationary radar.

Professional line of MS-508 SIGNAL PROfessional.
SIGNAL PROfessional multiswitches is a group of professional multiswitches designed for the implementation of modern RTV/SAT installations in residential buildings and small and medium-size commercial buildings. Using the MS-508 SIGNAL PROfessional R69508 as an example, the key features and design principles of this series can be identified:- 5 inputs (4 × SAT from a quattro converter + 1 × DVB-T2/Radio)
- 8 independent subscriber outputs
- possibility of cascade operation
- high mechanical resistance
- efficient shielding (Class A)
- efficient heat dissipation
- LED indication on the outputs helps to verify correct operation and quick location of possible problems
Multiswitches of MS-508 R69508 series are used both in single-family houses,
as well as in small community installations (e.g. multi-family buildings or offices).
as well as in small community installations (e.g. multi-family buildings or offices).
The SIGNAL PROfessional MS-508 R69508 series is designed for stable and high-quality distribution of TV and radio signals. The devices of this line allow simultaneous transmission of satellite signals, terrestrial digital TV DVB-T2 and FM/DAB+ radio to 8 subscriber outlets, while maintaining high transmission quality. The pass-through design makes it possible to combine several multiswitches into one installation (e.g. up to 4 devices without additional amplifier), which increases the scalability of the system.
Schematic diagram of an IP video-intercom installation for a house with three condignations.
Below we present a diagram of a Hikvision IP video-intercom installation for a 3-level house. The installation has been based on the Villa DS-KV6114-MWBE1 G73613 single-substance IP door station with a built-in 2 MPix camera and 2 relays to control the gate and entrance gate. DS-KH8381-WTE1 G74007 monitors equipped with Wi-Fi were installed on three floors and configured in extension mode. This means that when the call button on the door station is pressed, all monitors will ring at the same time. When a call is answered on any of the monitors, the others will be disconnected. An Ultipower N299851 switch with 8 PoE ports in the 802.3af/at standard was used to power the door station and monitors. The system was connected to the internet network using a Mercusys AC12G N2933 router. The wicket was fitted with a Bira S12U symmetric door strike from the Hartte G74220 series with an adjustable jaw of up to 4 mm, which is suitable for 12 V DC or AC operation. A 12 V DC power supply M1820 was used to excite it.IP video intercom system for a single-family house.
IP Addressing - Part 1.
In order to exchange data between at least two computers, a dedicated computer network must be established. In such a network, devices communicate with each other via transmission media using appropriate communication protocols. Nowadays, it is not only computers and servers that are connected to a computer network, but also CCTV devices, alarms, smart home components or household appliances.When configuring the network interfaces of such devices, the user is asked to enter the following network settings:
- IP address,
- subnet mask,
- network gateway,
- DNS,
- ports (for specific services).
Each network device has its own IP address.
Example of setting an address (192.168.1.32) for an IP CCTV camera.

IP address is the host identification number that is used for proper communication between devices. The IP address is a number assigned to a network interface, a group of interfaces (broadcast, multicast addresses) or to the entire computer network, used to identify network components and being one of the elements enabling them to communicate.
Two IP address versions can be distinguished:
- IP version 4 (IPv4) – the IP address is a 32-bit number (from 0 to 4294967295), written in big endian format (data notation in which the most significant byte is placed first). The address is written as 4 separate bytes, called octets, since they have eight bits in a binary form. Those eight bits give 256 combinations, so each octet represents a number from 0 to 255. Sample IPv4 address: 62.121.130.38
- IP version 6 (IPv6) – IP address is a 128-bit number not in decimal but in hexadecimal code. That means that the IP address consists of eight groups of digits, four digits from 0 to F in each group. Unlike the previous protocol version, the address range, i.e. the area of its visibility, is limited by the appropriate prefix. Sample IPv6 address: 2003:0db8:0000:0000:0000:0000:1428:57ac

How to extend and branch PoE power supply? A PoE extender is a device used in Ethernet networks that allows you to extend the range of data transmission and PoE power supply in a single LAN cable. It allows you to connect devices such as IP cameras, Wi-Fi access points or other network equipment at a location away from the main network device, such as a PoE switch or NVR. In a standard Ethernet installation, the maximum length of a single cable is approximately 100 metres. The PoE extender is installed along the cable route and acts as a regenerator of signal and power, which it passes on to the next section of cable. This allows the distance between devices to be extended without the need to supply additional power...>>> more
