Serial Over IP can be implemented in two different ways: Terminal server operation is defined by RFC2217 and basically maps a serial port (RS-232) to a telnet network port. This allows a user to open a telnet session to that port and then enter commands that are passed directly to the mapped serial port.

Serial Over IP modem mode allows the serial port on one device to be mapped to the serial port of another device. This essentially creates a null modem connection between the two serial ports over the network. This mode of operation is used for such applications as attaching a joystick to one end of a network link and the Pan, Tilt controller to the other end, allowing remote control.

Terminal server operation is very basic and allows pretty much any serial device to be controlled remotely, if you know the command structure. Terminal server session can be scripted using tools like cURL so it is pretty easy to build a working interface around a terminal server.

Both the HauteWRAP and HauteROUTER product families have terminal server capabilities as options.

Modem mode is transparent. Serial connections at both ends are made and the Serial Over IP devices exchange the serial connections. In the HauteROUTER products this is done using multicast and connections can be made in one to one or one to many. It is more flexible and easier to use if you are just trying to move serial connections around.

Serial Over IP is a very flexible tool which remains useful, even as serial protocols give way to IP.
 

Links to Wireless Solutions

For the last three years HauteSpot Networks has been carrying the banner for the use of IP broadband wireless in surveillance. The security industry has been very slow to adopt wireless IP for a number of very valid reasons. The problems with IP broadband wireless for moving video have been significant, as many early adopters have found out the hard way. But we have reached a point where manufacturers like HauteSpot Networks, have resolved the issues. The trade publications are starting to support wireless, and the market researchers are bullish on the technology.

Installation - Initially, installing IP broadband wireless surveillance was a complex proposition. Security installers had to have the skills of a network administrator, RF engineer, access control specialist, and CCTV technician. HauteSpot Networks has greatly simplified this process with simple, web based tools, that allow an installer to configure and align an IP broadband wireless router in under 5 minutes. A complete set of system administration tools are always present for troubleshooting when needed, but are obscured from view when not required.

Wireless Protocols - Early adopters tried analog wireless, WiFi, and mesh protocols for their surveillance video and found that they just did not scale or perform as promised. Jitter, delay, instability, lost connections, etc. were common problems. Routing delay and variability were also common issues for mesh, causing most installations to be configured less mesh-like and more deterministically.

HauteSpot Networks TDMA protocol sets resolves point to multipoint issues and scales seamlessly, without complexity. The HauteSpot HauteLINE protocol for point to point links provides unrivaled performance for backhaul or high definition video links. The protocols are designed for video, not data, and work as designed.

Cost - WiMAX and LTE promise to, someday, be cost effective technologies for surveillance. Right now these technologies are focused on the telecommunication carrier market and they simply aren't designed for the needs of private security networks. Base station and remote equipment are too expensive to meet the needs of surveillance. In a few years you will be able to pay a third party network operator to provide you with wireless bandwidth to meet your security needs, but today you can't get the bandwidth required for video surveillance at a price you are willing to pay.

HauteSpot Networks delivers solutions that meet the bandwidth needs of video surveillance today, at a price that is within reason. Our complete architecture includes high performance backhaul and master node solutions, lower cost end node solutions, video encoders which are optimized for wireless operation, free network management software, user management software, diagnostic tools and more.

Performance - Up until recently, multi-megapixel, high definition camera manufacturers have left wireless technology out of their network design recommendations. Their cameras needed bandwidths that exceeded what traditional wireless equipment could support. But as security becomes more and more critical, cameras need to be located where wires (or fiber) cannot always reach.

HauteSpot Networks HauteROUTER product family was designed for streaming video performance. With the HauteLINE protocol, data rates of up to 65Mbps (UDP) can be reliably transported, enabling high definition, high speed video to be placed anywhere.

Yes, wireless surveillance has arrived, is proven and is ready.

On September 1 we moved to a new office in downtown San Luis Obispo. Our new office is within the same shipping zone, etc and the office change will have not effect on our delivery schedules. Our phone system and staff all remain the same.

As always, the HauteSpot Networks team is ready willing and able to answer any of your video over wireless broadband questions. Call us and see how we can assist you.

HauteWRAP^TM Product Family TDMA and Simple Interface

Beginning with release 3.14 of the HauteRouterOS system on the HauteWRAP product family, we have begun to offer two major changes to our systems. Both are intended to simplify our systems and make them faster to install and use.

First, Time Division Multiple Access or TDMA mode is the default operating mode for the system. When HauteWRAP products are shipped, they will have a default operating mode of TDMA, not 802.11. The TDMA protocol is designed specifically for video IP applications over wireless. It does a number of things, including:

• It eliminates collisions that cause jitter
• It provides equal bandwidth access
• It provides more even data spacing (also reducing jitter)
• It reduces the hidden node problem that effects WiFi
• It provides better scalability when compared to WiFi or mesh protocols.

Setting a HauteWRAP back to standard 802.11 operation is simple and can be done by any administrator via the console or client-server application with one simple command.

Second, all HauteWRAP products will now be shipping with a greatly simplified web interface, designed specifically for installers. In two simple pages, the installer can set all of the parameters for the system and align the antenna for optimal signal. Installers need very little network experience and can easily be trained to use this new interface.

There are two user accounts for the system by default. "Install" only has access to the web interface and basic configuration features. "Admin" can access the system from telnet, ssh, or client-server application. For troubleshooting or advanced configuration, the Admin account can fully administrate all features of the system.

"So easy, anyone can do it...even my parents!"

For OEM customers we can also customize the web interface.
