Video Balun Transceiver with built-in Surge Protection.


The VB39F is a Passive UTP Video Balun for twisted pair transmission of CCTV video. The VB39F is a "heavy duty" design with two screw terminals for UTP connection and a female BNC for coax connection. The VB39F has built-in surge suppression for added equipment protection.

The VB39F Video Balun is a Transceiver that provides a low cost means of sending live video over unshielded twisted pair, point-to-point wiring for distances of up to 750 feet (228 meters), with other CCTV balun transceivers, up to 1,500 feet (450 meters) with the TR515 single channel receiver and model 51 series hubs, up to 3,000 feet (900 meters) with the TR560 single channel receiver and 56 series hubs. The VB39F is compatible with all of the �up-the-coax� control systems.

A basic system uses (2) VB39 units, one at each end of a twisted pair of wires. These units are intended for use over existing in-house telephone wiring, Category 5 wiring or other twisted pair cable runs to provide a convenient, cost-effective alternative to coax.

The VB39F is designed to provide superior immunity from noise and interference even when running next to line power. The VB39F also provides a convenient mounting tab for ease of installation. The VB39F is a UTP transceiver that provides another Security Transmission Solution from Nitek.

Features:

  • Quality video over ordinary twisted pair cable
  • Immunity to noise and interference
  • Built-in surge suppression on VB39 model
  • Passive devices - do not require power
  • Video & P/T/Z over a single pair (with �up-the-coax� systems)
  • M - version mounts directly to camera or video source
  • Weatherproof design
  • Easier to install than coax

Applications:

  • Intra-building CCTV installations (instead of coaxial cable)
  • Structured cabling (Category 5) environments
  • To eliminate requirement for Plenum Coax
  • Multi-camera applications through conduit (more cameras through a smaller diameter)

SYSTEM COMPONENTS

Two VB37 devices M or F in any combination are required for transmission over a single UTP.


Wire and Cable Recommendations

The VB37 and VB39 are recommended for use with unshielded twisted pair (UTP) wiring. The systems will operate over wire gauges from 26 AWG through 12 AWG. Category 2, 3, 4 or 5 cable may be used. Individually shielded pairs should be avoided, as they drastically reduce the operating range of the systems. Multi-pair cable with an overall shield is acceptable.

Video can be operated in the same communication cable coexistent with telephone, computer, control signals, power voltages and other video signals. While video may be routed through telephone punch-down block terminals, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.

The hate you give; that end up making me LOVE YOU
You can tell that Ally had so many doubts when it came to Chase... Especially when it came to her feelings for him and how he felt for her. I figured he had a thing for her even though what he did at the dance freshman year was a bust... though it was the right thing to do for Ally though I believe he should've given Ally an option to decide that decision with Declan... her doubts with Chase has the present intervening with the past which had proven to see him being so different... but things can change....I think he hated her ONLY because she hated him... & jumped to a conclusion before he could explain to her why he did what he did at the dance... Same when she accused him of the photo when she went to that club and dancing on the pole.. she accused him and came to a conclusion that he did it... she only found out that he didn't do it... because Declan and Chase got into it; by Chase demanding him to apologize... Declan wasn't even worth the air she breathes in senior year or freshman year if you look at it.... plus Chase parents are horrible especially his father sheesh no one wants a parent like that... But oh.... when he (Chase) said: "I didn't have a choice, Ally, because if I didn't hate you, I would love you, and loving you would only break my heart." I knew that had to be the reason, and I knew he liked/loved her, but she was to blind to see through her hate for him... by getting mad about Declan who was the same person he was freshman year to senior year. I figure I was right too... but kind sad and thinking duh Ally when she stated: "I'd created an enemy out of a boy whose only fault was loving me, and my heart was breaking from his words." Sometimes you learn from your mistakes... but half the time I thought Tessa set Ally up with Chase so that feelings can start to show on Ally side since Chase already had feelings. No way; you think you not like someone; can't get rid of someone if you "hate them".. when you can you actually can't stand them; when you don't think you have feelings. No way I will be around someone or try rid them if I dislike them for bullying me down or hurting my feelings...they wouldn't be in the same home heck I wouldn't care what my daddy said... build me a treehouse I don't have time for living in a house with the enemy... in reality Chase was not Ally enemy he was her lover she just didn't know it yet.... but at least, in the end, he showed her that no matter what I'm coming for you "to make you my girl; because I always love you" and she finally stops running and agree to date him once she found out that her father knew about Chase loving her among other things. But besides that... UGH! I need a book with Ally twin brother Shane and her best friend, Tessa... I would like to see them together because she has a thing for him and he doesn't even know!!! But maybe he does!

Great Read!
Format: Paperback
Bought this booking looking to learn more about the processes of buying and managing real estate. Very informative and extremely helpful, not boring and straight to the point. Mostly written by his advisors but Robert does have some stuff to say before every chapter. All in all great read and I learned lots. Definitely a must as you’re working your way through his books.
