| If you need to securely link remote video cameras to a monitoring location, we are excited to say "We have the product!" You can now send a video signal over fiber with the VersiVision FVT1000/FVR1000 products. Need to control a camera with pan, tilt, or zoom features? No problem with the VersiVision FVT1100/FVR1100 with its return data signal capability. And these products are completely compatible with NTSC, PAL, or SECAM video standards. In addition, the new VersiVision modems provide high quality transmission of one channel simplex video at distances to 3 km using multimode fiber and distances to 30 km using singlemode fiber. A BNC connector provides the copper interface for the video input/output, |
and a DB9 connector provides the copper interface for the data input/output. RS-422, RS-485, and RS-232 data interfaces are supported. ST and SC optical connectors are standard. These transmitter and receiver modems are available as standalone devices for easy plug and play installation, or they can be ordered as circuit card modules for installation in the FVC-14 rackmount chassis. The 14-slot chassis fits in a standard 19 inch rack and is offered with either 110VAC or 22VAC power supplies. Please see Page 2 for details. All VERSITRON advantages are extended to these products including free and unlimited telephone tech support, and a Lifetime Warranty. |

Tighten Up, Hunker Down!
In these security conscious times, we need all the advantages we can get. As was painfully demonstrated these past months in the UK, reliable video surveillance equipment is the very cornerstone for assuring our safety as well as for catching any perpetrators of "dastardly deeds" who may slip through the net. If video equipment installed over copper cabling is good, video equipment installed over fiber optic cabling is better!
There are reasons why fiber optic technology was embraced by the government and military at the height of the cold war. While the basic threat may have changed, the reasons for embracing this technology have not.
A fact of life: signals sent by way of electric current over copper cable are vulnerable in several ways. Sending signals by way of fiber optic light transmission eliminates the possibility of ground loops, lightning hazards, ground potential rise, and transient spikes. Such issues can at the very least "ruin your day" and at the very worst can leave your entire security system breached. In today's world, can we afford to take the chance?
And because fiber is dielectric, detecting signals sent over it is difficult. The first roadblock against tapping is firmly in place. Another roadblock to tapping fiber is due to the properties of fiber itself. There would be too much signal loss for the effort required to tap into it. In other words, it just isn't worth it.
These are reasons enough to choose fiber. But there is more! Signals sent over fiber are also immune to EMI/RFI, thus keeping your signal "pure" and non-degradable. (No environment worries with fiber!). Signals can be sent longer distances over fiber, eliminating the need for repeaters. And don't forget that the available bandwidth with fiber is greater too, making it possible to send more information much longer distances. Distance capabilities can be as high as 90 km., and you can even send audio, video, and data signals at the same time.
What about cost? With today's competitive pricing of fiber optic cable and hardware, coupled with easy installation and system upgrades, there is no reason NOT to choose fiber over copper.
All of these advantages of fiber translate well into fiber to the desktop applications and various campus environment scenarios. Specifically for CCTV applications, you can expect a higher signal quality maintained over longer distances.
And so to secure your video, audio, and data signals absolutely with a minimum possibility of a breach, the days of the "fiber optic advantage" are here. Bottom line: "You can't beat the peace of mind".

Network Administrators:
Take The Helm!
with our upgraded "management capable" fiber optic switches. The VERSITRON 5-port, 16-port, 24-port, and "Pick-a-Port" modular switches now have management bragging rights. The "Pick-a-Port" modular switch sports both basic management and advanced management activities including web based and remote monitoring options. You can view and configure the switch for VLAN, MAC address, IP multicast group and port perspectives.
There are options to "tag" and "untag" packets so that priority information is recognized. Through the QoS set up, you can transfer packets with different priorities, different drop rates, and different bandwidth allocations for different requests of packets. You can "queue" these packets by profiling them as strict priority, delay bound, weighted fair queuing, and best effort. Thus ensuring, the most important data the highest of priorities. Additionally, you can "see" the file transfer packets, allowing you to always know which port is up and which port is down. You can also have the option of increasing bandwidth through trunking (hooking one switch to another in full duplex). And, if you need to separate departments over separate networks, the VLAN option will allow you to set specific ports on specific networks. You would be able to configure ports 1-10 on network and 11-20 on another network. And these ports would never "see" each other at the switch level.
Other capabilities under the heading of advanced management include IP networking, DHCP support, routing table, ping, bridging, and static filtering.
The 5-port switch has a web-based interface for easy management. It supports static IP mode and DHCP dynamic IP mode along with VLAN configuration.
The 16-port and 24-port switches are now basic managed switches with General Management, LAN port, and Console Port capabilities.
So, grab the tiller, and navigate your way through calm "network seas" with the help of these versatile managed optical switches.
Sail Away to Switches
Load 'Em Up...
You can now make use of all 20 slots in the VERSITRON HF20 chassis AND maintain redundant power. The new AC300WR power supply can make this happen for you. Yes, a fully loaded chassis with redundant power is now possible for any of the FOM II products, including the F2238. For those who prefer a single power option, the A300W power supply will accommodate you--again with a "full rack".
