The PAV is solidly built, with a vandalism-resistant stainless steel housing and impact-resistant glass over the video screen. It can endure a heavy day-to-day workout and still stand up to attempted damage. The handset cord is rated to a pulling power of 667 pounds. Optional glass over the camera protects against spilled liquid and the unit is fully water-resistant. PAVs have been installed in prisons, where their robust construction has kept them operating under difficult conditions.
