As the leading engineering validation and certification laboratory for technical products, Allion Labs, Inc. has been authorized as a first certification test laboratory of Security Link Over Coax (SLOC™) solution by high-performance analog and power management semiconductors company, Intersil Corporation. Allion is currently the only test laboratory that offers SLOC™ Certification Program around the world.


The SLOC™ solution is designed to simultaneously transmit analog CVBS video and digital IP video over a single coaxial cable. SLOC™ supports distances up to 500 meters of coaxial cabling and also provides HD resolution transmission. In the past, digital IP video might encounter transmission delay caused by network bandwidth, temporary storage from video decoder and other reasons, and the use of CCTV coaxial cables also has lots of restrictions for application.

Based on this hybrid technical framework, SLOC™ allows IP cameras to operate in the existing CCTV coaxial cable infrastructure without the need for new wiring or cable modifications, providing significant cost and resource savings. SLOC™ also supports latency-free analog CCTV functions as well as networked IP surveillance, meeting the need for efficiency of real-time image transmission and cloud control. As for surveillance system manufacturers, they can more effectively enhance the performance and overcome application limitations. The so-called SLOC™ Certification Program can assure that manufacturers’ products conform to the request of specification.

As the authorized test laboratory offering SLOC™ Certification Program, Allion would assure that manufacturers’ products conform to the request of specification and help manufacturers with obtaining SLOC™ logo through complete professional SLOC™ Certification Program and technical consultation service.  Besides, Allion provides debugging analysis for device’s usability, interoperability and validation of networking to create a more reliable quality for examined products such as CCTV, video player/recorder, AV signal transmitter and receiver…etc.  For more information about SLOC™, please refer to  For SLOC™ Certification Program or other support, please contact Allion at
