Technology at Work: USING EXISTING NETWORK REDUCES CABLING AMONG BUILDINGS
An IP-based video surveillance system was specified for a campus of buildings at Crevier BMW, Santa Ana, Calif., the largest BMW dealership in the United States, at the suggestion of the dealershipâ€™s IT manager and because it was substantially less expensive in cabling and installation costs.
â€œWhen I came to the dealership in January of 2005, they had already gotten five or six different competitive bids on traditional coaxial analog camera systems,â€ relates Howard Holton, Crevierâ€™s IT manager. â€œBeing the new head IT person, I said, â€˜Letâ€™s take a look at this IP technology. It has been around a while, and that will lower our infrastructure costs and give us better management.â€™
â€œSo we just basically turned around and asked the companies that had given us bids to rebid against themselves in an IP versus traditional analog-based system,â€ he recalls.
Janelli Kelsey was working for one of the companies that bid on the job. â€œWe ran two scenarios, one analog because it was quoted previously and he wasnâ€™t happy with what he received,â€ reports Kelsey, who is now an outside sales account executive at southern California distributor Walters Wholesale, Signal Hill, Calif.
â€œWhen we ran the comparison, not just for the first phase but the whole project from start to finish, there was about a 60 percent difference in costs to the end user,â€ she explains. â€œSince itâ€™s a campus environment, networking the video saved tons in cabling costs. With an analog system, it would have been fiber, trenching, all the fun stuff we donâ€™t like to do if we donâ€™t have to.
Adds Holton, â€œThe IP system is a significant saving over the traditional analog design, especially when youâ€™re looking at DVRs. The cost for the camera hardware is a little bit higher, but the NVR server can handle up to 64 cameras without a problem, so thatâ€™s really where we saw the big cost savings.â€
As a result of Crevierâ€™s lack of employees dedicated to security, Holton had that responsibility added to his duties, which already included telecommunications, IT networking and facilities management. With IT as his primary responsibility, it was only natural that Holton would consider an IP-based solution.
â€œWe were able to run everything into our main data facility and have one punch down there,â€ Holton says. â€œWe were able to use our standard Cat 5e cable rather than running a new set of coax cable. The only thing we had to do was to create a separate network for much of the video system.
â€œOur main network is 100 MB per second and the video was using up, or trying to take up, about 70 percent of that,â€ Holton relates. â€œNow itâ€™s down to about 30 percent.
â€œOne of the nice things about the cameras we chose is weâ€™re able to pick on a camera-by-camera basis what size video weâ€™d like to get from the cameras,â€ he explains. â€œThe system uses MPEG4 compression, which only records frame changes, so if you have a reasonably static picture, you have very little data being recorded and transmitted. It reduces the network utilization on the camera system.â€
Because the installation was on an existing network, an integrator with data and security experience, Data Installers, Chino, Calif., was selected for the job.
â€œWe did the installation of all the cameras and the running of the cable and conduit for all three buildings,â€ relates Edgar Estevez, Data Installersâ€™ co-owner. â€œIt took us a week â€“ four guys, 10 hours a day to finish the installation.â€
That bane of security installers â€“ voltage drop over longer cable runs â€“ figured in this installation. â€œWe did have a problem with the distance of the Cat 5e for power,â€ Estevez concedes. â€œAround 200 feet, it started failing, so we had to run bigger gauge cable for the power for the cameras. We went to 16-gauge, and that worked a lot better.
â€œWhat it was doing was the PTZ would work, but when it started moving and it was over 250 feet, it would turn off, and they would reboot and start all over again,â€ Estevez explains. â€œIt took us a little while to troubleshoot all that.â€
Holton agrees. â€œWhat we found was if the length got around 200 feet, because 18- or 20-gauge wire is in Cat 5e, it would lose so much amperage it wouldnâ€™t power the PTZ,â€ he states. Running extra power was not necessary for closer distances, he notes.
The cameras are able to capture numeric information from an identifier tag that hangs from the rear view mirror of each vehicle. All of the cameras are recorded into the network video recorder through Infinovaâ€™s video management NVR software.
The information then can be recalled by any authorized user on his or her PC. Holton identifies the cost-effectiveness of this approach as yet another factor that motivated him to select an IP solution.
Established in 1971, Crevier sells approximately 5,000 to 6,000 vehicles per year, including Mini Coopers, a BMW-owned brand. Before the new surveillance system was installed, the dealerâ€™s security system consisted of three â€œold fixed camerasâ€ that were not doing much of anything, according to Holton.
The new system covers each of four facilities that comprise the dealership. A total of 16 PTZ domes are installed in the main facility, which house administrative offices, new car sales and the service department. Additional cameras are located at a facility devoted to the Mini Coopers and another building considered a remote service facility.
Eight stationary cameras are traditional analog ones and are run through an analog to digital converter. â€œWe didnâ€™t need the PC capability because we have so few of them, and thereâ€™s also a size advantage to the analog cameras because thereâ€™s no PTZ,â€ Holton points out. â€œTheyâ€™re very small; you can put your hand over the whole dome. Theyâ€™re less obtrusive; you probably wouldnâ€™t know they were there.â€
The system will be expanded to cover a fourth building that just had been completed at press time. The six-story building, which will house a large parking garage and the resale department, will add about two dozen IP cameras to the system.
After several months of operation, Holton is pleased with the IP-based system and looks forward to working with the company and Walters Wholesale on the next phase of the project.

- The Greater Laguna FireSafe Council in the San Diego area is deploying IPELA SNC-RZ25N video surveillance cameras from Sony Electronics, Park Ridge, N.J., linked by wireless networks, to help catch, contain and extinguish flare-ups before they become wildfires. Since its creation in the mid-1990s, the councilâ€™s Red Flag members patrol the Laguna Beach region in cars marked with magnetic signs and window flags. In 2003, David Mitchell, president of PRO 911 Systems, suggested extending and enhancing the lookoutsâ€™ capabilities with the surveillance cameras. His company helped create high-speed wireless Internet access across Laguna Beach by creating a Tropos MetroMesh wireless network. Now those dispatched can access the critical video and operate the cameras with wireless-connected laptops and hand-held computers.
