Ways to Extend USB Cable over Long Distances

If you come across a situation where there’s a need to extend a USB cable over 25, 50, 100 feet or even longer distances there are a few solutions available on the market to choose from today. It’s all about inherent maximum cable length limitations of the cable type as well as the quality of the cable solution we select.

Before we get into USB extension options you need to understand the underlying UBS cable length limits.

  • Maximum length of a cable between USB 2.0 devices is 5 meters or about 16 feet.
  • Maximum recommended length of USB 3.x cable is 3 meters or about 9 feet.

With USB active cables aka repeaters the max length limit depends on whether a regular USB cable with an active cable or not. For the active cables the maximum active cable length for USB 2.0 is 98 feet and the maximum recommended length for USB 3.x is 59 feet. If you are using a regular with an active cable, then the maximum length for USB 2.0 is about 82 feet and the maximum recommended length for USB 3.x is about 49 feet.


Running HDMI over Ethernet Cable

There are two major reasons you’d want to run HDMI signal over Ethernet cable:

1. If you have to run the cable over long distances HDMI cable is not the most reliable. Ethernet cable, Cat 6 specifically, on the other hand, is way superior when it comes to reliably transmitting signal over hundreds of feet. It’s also less expensive.

2. You spend all that money of a glitzy 4K Ultra HD TV set and had it neatly mounted on the wall. But you still had to run the cables from TV to DVR, Blu-ray Player, what have you. All of that equipment is likely staked up in the TV stand/console nearby. It’s got to be a better way.

Absolutely. You can run HDMI audio, 1080p, 2K and 4K video and IR signal for your remote up to 220 feet using only a single Cat6 cable and have all of your video equipment neatly stored somewhere in the basement in an enclosed rack or cabinet. The product is called HDMI Extender or 4K HDBaseT Balun and it the set consists of one transmitter and one receiver – one or both powered by AC adapters. The built-in IR extender in HDBaseT adapter allows IR remote control of source devices from a remote viewing location by sending IR commands received in the vicinity of your TV set back to the source devices. This device is 4K, 2D and 3D compliant and it runs at 340 MHz bandwidth.

There are a few things to note.


Register Your Private Surveillance System To Help Fight The Crime in Philadelphia

Since thousands of surveillance cameras are installed in and around the city of Philadelphia, but only a couple hundred actually belong to the authorities Philadelphia Police Department has encouraged camera owners to register their private cameras with the police department. The idea is to save investigative time and could help police solve crimes faster.

The PPD wants to build a database of all registered cameras so that when a crime happens in the particular part of the city, detectives will already know that there are cameras nearby.


Cat 8 Cable – What Does The New Standard Mean to Future Networks?

One of the more significant outcomes of the meeting of the Telecommunications Industry Association’s TR-42 Engineering Committee back in January 2016 was the announcement of the Category 8 cable standards.

Category 8 is the next generation twisted-pair copper cabling specification that is still being finalized (as of February 2016), featuring two conductor pairs with maximum signal rates at 2GHz (2000 MHz) – four times the Cat6a cable bandwidth of 500MHz!!!

Class I, Class II and Category 8 cabling is characterized to 2000 MHz and intended to support up to 30 meter long cabling channels consisted of two connectors. These channels and the emerging 25/40GBase-T applications that they support are specifically tailored for deployment at the data centers, where bandwidth intensive server-to-switch connections are made.

The preliminary tests of Cat8 cable have shown it meets connectivity performance standards found in the draft 2.0E of the TIA-568-C.2-1 Category 8 proposed standard and can support the operation of IEEE 802.3bq 25G/40GBASE-T applications up to 30 meters.


Video Surveillance Systems – Commonly Asked Questions and Considerations

Does Video Surveillance Prevent Crime?

The answer is twofold.

On one hand, wherever one facility has signage displayed prominently, warning the passers-by about presence of a surveillance or CCTV system and/or the cameras are mounted in a visible areas and the other building has none of these items a potential perpetrator will likely select the latter as his target.

Even the carrier criminals may be are well aware of the shortcomings of today’s video surveillance systems and likely plan their acts around them; they will think twice before targeting a residence armed with security cameras, even if they chose to wear disguises, i.e. masks, sunglasses and hats.

On the other hand, those who engage in criminal activities are not your average Joe’s and are often driven by irrational factors, such as mental issues, substance addiction or otherwise sociologically abnormal. They don’t take time to analyze whether there’s security monitoring system at the place they’re about to hit, nor ponder potential consequences of their action as they often act determined and swiftly.
