Productbeschrijving

Dahua VTH5221DW-S2 is een nieuwe kleuren IP-video-intercom met een ingebouwde Wi-Fi-module die de prestaties van netwerk multi-abonnee oproeppanelen en camera's ondersteunt, inclusief op afstand via een smartphone of tablet. Videogesprekken met andere intercoms die zijn verbonden met het interne SIP-netwerk worden ook ondersteund.

Ethernet-netwerk via poort RJ45 (10M / 100M) werkt via TCP / IP, Wi-Fi-netwerk ondersteunt IEEE802.11b / g / n-communicatiestandaarden.

De intercom is uitgerust met een 7-inch kleuren touchscreen LCD-scherm. Om het werk en de instellingen te beheren, wordt het hoofdmenu op het scherm gebruikt in de vorm van een gebruiksvriendelijke interface.

Het is mogelijk om oproeppanelen en videocamera's aan te sluiten op de intercom. In de intercommodus kunt u nog een paar monitoren van dit bedrijf of een conciërgeapparaat aansluiten. Dit maakt het mogelijk om audiocommunicatie met deze apparaten te onderhouden.

Alarmdetectoren zijn aangesloten op 6 bedrade ingangen en maximaal 8 draadloze zones (ondersteunen slechts 433 MHz), en actuatoren zijn aangesloten op 1 uitgang. Wanneer een van de detectoren wordt geactiveerd, wordt het opnemen van een foto of video op een geheugenkaart tot 32 Gb ingeschakeld.

De video-intercom wordt van stroom voorzien via een externe voedingseenheid DC 12 V of PoE-technologie (IEEE802.3af).

Dahua VTH5221DW-S2 is gemaakt van duurzaam kunststof in wit (VTH5221D W-S2) of zwart (VTH5221D-S2). Het apparaat wordt op een overhead manier aan een muur of een andere handige plaats gemonteerd

    I wish it had been done better
    I imagine I'm going to get unhelpful votes by saying this, but this biography was not up to par with the author's other biographies. I've read Titan, which I thought was great, House of Morgan, which was really good, and Hamilton, which was also good, and this book just isn't up to those other books. The beginning was very frustrating because we learn about this supposedly very successful and widely acclaimed and established German banking family, yet there is practically nothing concerning how they got to be well known and exceedingly wealthy, nor what their business dealings were at the time. And this lack of information goes on and on, focusing almost to exclusion on inter-personal issues. Looking up the Warburgs in Wikipedia, I learned that the family had been a very successful banking family from the 1600's back in Venice, even before they settled in Warburg, Germany. Starting the narrative in the mid to late 1800's with the success of Jews in what was to become Germany just left me hanging and feeling like I was missing a large part of who the Warburgs were and how they got that way. Additionally, the family had been around for a very long time and there are scattered references to visiting or staying with uncles and aunts, but the overall breadth of the family is not addressed. Thinking about his problem now, it almost would make more sense and read better if there was a short intro and perhaps 10 separate bios on separate family members, instead of skipping around. It would help the flow. I have a feeling the author's inability to read German or Swedish or other European languages and his lack of primary research in Europe, where the Warburgs achieved fame and fortune, contributed to this incomplete biography. On the other hand, it appears that not much had been written on the Warburgs prior to this book (at least in English), and that is why I read the book. Additionally, the whole build up to the Holocaust and how the Warburgs kept their warm feelings for Germany throughout the experience, as a constant theme, was very interesting and well done, especially since I'm Jewish. The reading got more focused and poignant the closer the Holocaust got and immediately afterwards. 3 or 3.5 stars is probably the best score, but will upgrade so I don't get canned too badly. If you're interested in the Warburg it's a good starter book, though I imagine if this weren't one of the first books Chernow wrote, he would have done a better job as a more mature and accomplished biographer.

    Well Worth the Lengthy Read
    Format: Paperback
    Enjoyed this book. Ron Chernow writes well, captures personalities and researches extensively. I went to Woodlands High School on an estate donated by the family. These were brilliant people who stood by their values and convictions while facing anti-semitism with grace and courage.

    A brilliant family, cultural and business history
    Format: Kindle
    What starts out as the personal and business history of a deeply religious and close family, expands into a study of the disintegration and continued importance of family, religious and cultural ties, the sources of anti-semitism and a window into some of the most dramatic moments of war and peace in the 20th century. Brilliantly researched, and interestingly written, it touches on topic after topic of importance, without pretence, and without either glorifying or deprecating the many contributions of the many Warburg family members it follows. Deserving of some high award, for sure!

    Wow ! What a great read
    Format: Hardcover
    I've read most of Ron Chernows books and they all are just overpowering. The history that you will learn is astounding, and it comes to you as a wonderfully told story. The Warburgs, will put the pieces of the history puzzle together from pre-WWI Germany to the Treaty of Versailles, WWII, post-WWII Germany, plus Warburg involvement with the creation of the current US Central Bank and service on the board of the Federal Reserve. The story covers the split of the family telling the stories of those who remained in Germany some of whom suffered death in the Holocaust, while others lost wealth, position, and sanity yet one remained relatively unscathed building a library of great works while in Germany through Hitler"s reign. The journey of the family is a European, American, and Anglo journey, of a family that prospered and suffered and prospered again leaving it's mark on history for the last three centuries, and still survives.
