New vision of home monitoring from Amazon.

American technology company Amazon's Ring has recently unveiled a flying and room-monitoring camera that activates when sensors detect a potential home intrusion. The drone-like camera, named Always Home Cam, is designed for home surveillance and only activates when the occupants are away. The camera operates indoors and can travel within one floor of a building. If an intrusion is detected, the owner receives a notification on their smartphone and can view the camera live. Amazon assures that it cares about owners' privacy at the same time and the security system only sends reports when the camera is in motion. If it is at rest in the docking station, the system is physically locked. On top of that, the camera drone is loud enough to be heard when active. The solution, when it goes on sale, is expected to cost $250 and will only be available in the US at first.
Indoor flying security camera is always watching over your home.
"The Always Home Cam is an advanced device that for many consumers will seem like an invention straight out of a science fiction movie" – Ben Wood of consultancy CCS Insight commented. He added that he expected the camera to spark huge interest among "smart home" enthusiasts. However, it will also likely trigger a huge discussion about privacy and the future role of technology in the home. Amazon has been using drones to bolster its delivery network for years. In the past, the company's patents have suggested that drones would also be able to provide surveillance services. Ring's future products could include drones that move around the home in more than just suspected break-ins. Doesn't the "electronic, flying guardian-drone" sound a little... creepy?

SMATV/SAT system.

Systems based on multiswitches are professional and the most popular way to deliver terrestrial TV (FM/DAB and DVB-T/T2) and satellite SAT (DVB-S/S2) signals to more subscribers. It is the end-user who decides what programs to watch by purchasing the appropriate satellite receiver or by signing an individual contract with one of the digital platform providers. TERRA products, dedicated to use SMATV systems, are primarily top-class equipment covered by a four-year warranty. TV systems based on those components guarantee great signal reception for long.
The multiswitch system in one of the housing developments in Skawina near Krakow is based on TERRA equipment.
An antenna mast has been mounted on the flat roof of the building, on which a 120 cm satellite dish is suspended, ensuring reception of signals from two satellite positions: Hotbird 13°E and Astra 19.2°E. For terrestrial TV DVB-T/T2 in UHF band, the Dipol 44/21-60 Tri Digit A2670 and, for FM radio, the Dipol 1RUZ PM B A0221 antennas are used.
The TV system uses the SA-91L R70901 amplifier for 9-input multiswitches of the serii MV-9xx series. The amplifier is equipped with eight satellite inputs and one DVB-T/T2/Radio input, allowing to amplify and equalize the input signals of the system. The signals are then distributed via the SD-904 R70523 splitter to two MV-924L R70874 multiswitches.
The key functions of the SA-91L R70901 amplifier include:
  • amplification and equalization of IF signals for 8 polarization-band pairs,
  • amplification and equalization of DVB-T/T2 and radio signals,
  • attenuation of LTE signals,
  • compensation of attenuation characteristics of coaxial cable,
  • powering other components of the system, such as LNBs, DVB-T/T2 preamplifiers, multiswitches or other bus amplifiers,
  • elimination of external interferences thanks to die-cast housing (class A shielding level).

Video intercom system for one-family house - IP Hikvision of 2nd generation.

A diagram of the Hikvision IP video intercom system for a single-family house is shown below. The system is based on the DS-KD8003-IME1/EU G73652 door/gate station main module with a built-in 2 MP camera, one call button and 2 relays to control the wicket and the entrance gate. Two 7” DS-KH8350-WTE1/EU G74003 monitors with an IPS display are installed in the apartment. The Ultipower N29980 switch with 4 PoE ports supporting 802.3af is used to supply the door/gate station and monitors. The system is connected to the Internet via the TP-Link Archer C7 AC1750 N3262 router. The wicket is controlled with the use of the Bira ES1-001 G74210 electric door strike with steel keeper/latch with 4 mm adjustment range, suitable for 12 V AC or DC power supply. It is supplied with the 12 V DC M1820 power supply.

IP video intercom system for a single-family house.
On pressing the button, both panels in the house start ringing in parallel. After answering the call by the resident, two-way audio/video communication is established, and the resident can release the gate/door strike. In the absence of the resident(s) in the apartment, the call can be redirected to a smartphone, and its user may open the gate remotely. The built-in 256 MB memory in each of the monitors allows for recording photos, messages, as well as for leaving information in the absence of residents. The application Hik-Connect is dedicated for a smartphone control. For configuration and operation with a PC, the client application iVMS-4200 is available.

Smoothing of video streams in Hikvision IP cameras.

Imaging techniques are constantly evolving, resulting in recordings with higher resolution, high frame rates, wider dynamic range and more detail. This is usually accompanied by an increase in the amount of data generated by the camera. Higher bitrates can cause problems when viewing video over a network with too little bandwidth.
Smooth streaming is a feature that ensures smooth viewing of camera images regardless of the network bandwidth. When the network bandwidth is too low, the bitrate of the stream and the resolution are changed to view the image smoothly and without distortion. The self-correcting processing mechanism handles the delays and artefacts caused by packet loss or transmission errors. The feature is available in Hikvision 5 series cameras.

Installation and protection of fiber optic mechanical splices.

When deciding to join fiber optics using mechanical splices, it is important to remember that standard splice boxes as well as thermal splice mounting locations in fiber optic boxes and switch boxes are generally not sized to accommodate mechanical splices. Due to insufficient space, the installer decides to fix splices with insulating tape or, even worse, with hot-melt glue, or leaves them loose, which often leads to a mess in the box or switch.
Mechanical splicing does not preclude the use of solutions designed for thermal splicing (cassettes, boxes, etc.). However, it is important to buy appropriate holders for them. DIPOL offers two products that can be used depending on the number of splices to be protected:
Mechanical Splice Holder: USM-6 (for ULTIMODE FAST-MS1)
Protector for ULTIMODE FAST-MS1 mechanical splice  [5 pcs.]
Mechanical splice holder USM-6 L5556
allowing to fix 6 splices
FAST-MS1 L5559 (5 pcs. package) protector
protects a single splice

Facebook Wi-Fi.

With Facebook Wi-Fi, your customers can log on to your WiFi network with their Facebook account. In order to get free access to the network, customers need to check in at a given location (i.e., mark their presence at a given business on Facebook) so that it is visible to their friends. Each customer, upon logging in, is automatically redirected to that business' Facebook page.
WiFi network login using Facebook WiFi service
With this service, customers do not have to ask for a password to access the network and the business gains some marketing benefits. In order to create a WiFi network with this functionality (with such authorization method) one should have access points compatible with Facebook WiFi service. In the case of DIPOL these are devices of TP-Link Omada SDN series.

Virtual Host function in Hikvision NVRs. The most convenient way to connect IP cameras in the monitoring system is to use the PoE standard. It streamlines the installation (one cable for power and data transmission). The camera is powered by a PoE switch, which can be independent or built into the NVR. A PoE switch or PoE recorder is best suited for systems with simple architecture. The cameras are Plug and Play devices (the recorder activates the cameras itself), and most of the parameters are set via the recorder. The cameras function in an internal, isolated network and cannot be accessed directly...>>>more
