Innovative technologies have the potential to replace traditional TV commercials and could become standard in every second TV set worldwide within a few years. Industry experts predict that addressable advertising could completely replace classic commercials in the future. Despite the technology challenges, addressable TV is developing rapidly and can have a significant global reach. Dynamic ad insertion (DAI) allows broadcasters to customize advertising content for specific target groups. This...

Providers of DVB-T2/C transmission services via optical fiber mostly use traditional optical transmitters and receivers, e.g. the mo418 R82522 transmitter and the OD-005P R81760 receiver. Such connections use only separated cables with single-mode fibers, and the division of the signal to deliver it to different locations is carried out using passive optical splitters....

If a card reader is connected to the door stations of the modular IP video door intercom system (DS-KD8003-IME1(B) G73652) or 2-Wire (DS-KD8003Y-IME2 G73646), e.g. DS-KD-M G73662, it will be possible to control the first or second relay using a tag. The configuration can be done, for example, using the iVMS-4200 application or a web browser. After logging into the main module of the door station via a browser, first activate the second relay in the Configuration -> Intercom → I/O Settings tab, ...

The development of multimode fiber standards is mainly geared towards their use in data centers. The possibility of fast transmission over short distances and the use of spectral wave division multiplexing (SWDM) combined with the relatively low price of VCSEL lasers are the main reasons for the huge popularity of multimode fibers in this market segment....

A PoE switch is an advanced network device that allows simultaneous data transfer and power supply to connected devices via a single Ethernet cable (e.g. Cat5e, Cat6). Power over Ethernet technology eliminates the need for separate power supplies and electrical cables, which significantly simplifies installation and reduces infrastructure cost....

The ONVIF protocol enables the cooperation of IP cameras and recorders from different manufacturers. It allows the recorder to detect the camera, manage its settings, receive video and audio streams, and control PTZ (pan-tilt-zoom) functions in the case of cameras with such functionality. For the camera and the recorder to be able to work together via ONVIF, both devices must support this protocol and it must be activated (on Sunell cameras it is activated by default). In practice, this means t...
