Building from our expertise in communication systems, hardware and software designs, CVDS has become a leading supplier of Voice Recording Systems.

In the mid-1990’s CVDS developed a voice recording system for the air traffic control industry. It quickly became evident that the system was ideal for public safety as well. Since 1995, we have been supplying ComLog recording systems to all levels of public safety including police departments, fire & rescue departments, sheriff and county communication centers, state and provincial police, public health departments, campus security, and many others.

CVDS has an experienced team of engineers and technologists that are continuously adding features and functionality to the already successful ComLog Product line.

We pride ourselves in customer satisfaction, starting with the installation of the equipment by factory trained and certified technicians; to ongoing 24/7 customer support by CVDS employed technicians.
