Conformity Assessment
For FCC approvals, we operate an accredited Telecommunications Certification Body (TCB).The TCB system was implemented in 2000 by the Federal Communications Commission (FCC). It was created to allow the FCC to step out of the product approvals role, and to focus more on regulating and market surveillance.Until this system was implemented, most products which intentionally radiate radio frequency energy, and products which connect to the public switched telephone network, were required to be certified with the FCC. This usually meant waiting several months for an approval to sell your product. Compatible Electronics TCB (CETCB) can certify these types of products generally in less than two weeks.

The Flexible, Completely Modular CCTV Telemetry/Matrix System
UBS2000
One of the main advantages of the Telematrix system is the relative ease in which both large and small matrix systems may be conceived and assembled from a selection of only five basic components. The five main components forming the Telematrix are the Enclosure, the CPU Card, the Input Card, the Output Card and the Input Device (keyboards etc.). Cards simply slide into the enclosure on nylon card guides and secured by two small screws. Keyboards are connected by a flexible 4 core telephone lead and plug into the Telematrix using standard BT plugs (X2110, X2120) or via a standard 4 pair CAT5 cable terminating on RJ45 IDC connectors (X2140).

Utility Locator
VM-850
Using the correct frequency makes a world of difference when locating buried utilities. The depth of the utility, size, material, and amount of congestion (proximity of other utilities) all need to be taken into consideration for the correct frequency selection. Large diameter, direct buried pipes with bell housing ends that use insulators and rubber gaskets, such as water or gas require a higher frequency while smaller diameter, well-grounded direct buried or long distance in conduits work, better with a lower frequency. The VM-850 operates at a much lower frequency of 9.82kHz which is ideal for smaller diameter utilities such as CATV, power and telephone with less bleeding onto adjacent services.
