In the wake of the tragic suicide bombings in London last week, the media spotlight has been turned on video surveillance, and how the technology is being used to safeguard places such as transit systems. A company in the middle of this space is Ottawa-based March Networks, which develops IP-based digital video systems. It would be no surprise is March Networks' salespeople have been getting a flurry of inquiries from potential customers looking to beef up their security. Last month, the company, controlled by entrepreneur Terry Matthews, signed a deal to install digital video recorders in 80 rail cars operated by the Santa Clara Valley Transportation Authority in San Jose, Ca. In Toronto, there are growing calls for the Toronto Transit Authority to replace its aging video surveillance equipment. As much as no company wants to take advantage of terrorist acts, March Networks has found itself in the right place at the right time.
