Redvision, manufacturer of the X-Series PTZ and dome camera, says that it has identified a health and safety risk affecting incorrectly assembled, trailer-based, rapid deployment CCTV. Such systems are commonly used in remote locations or for temporary applications as self-contained, many trailer-based for towing to site by car. They might travel long distances to site, resulting in extended periods of continuous road vibration. Redvision says that its X-Series camera will withstand reasonable levels of vibration, however, it claims, some designs of rapid deployment systems are not so tough.
Paul Hucker, MD of Redvision, said: “Recently, we were made aware of a rapid deployment trailer using our X-Series camera, which was towed over 300 miles to site. The trailer had little suspension so the camera assembly was subjected to excessive vibration over several hours, resulting in the main camera fixings to the rapid deployment system working loose. The major concern being that no secondary fail safe method had been implemented.” The firm makes the following recommendations to installers and suppliers of trailer-
based, rapid deployment CCTV:
•All attachments should use lock-nuts or equivalent vibration-resistant fastenings
•All mountings should be securely and correctly fastened before transportation.
•The “Dynamic Mount”, pictured, should be used when attaching an X-Series camera to a rig.
•A secondary safety system is essential for trailer transportation. This could be a fabricated transportation cage.
•Only rapid deployment systems, where the manufacturer has undertaken suitable vibration and shock testing, should be used. This is a requirement for transportation applications.
•Responsible installers should request vibration test compliance certification from their rapid deployment rig suppliers.
Paul added: “Liability for accidents occurring from poorly made or maintained rapid deployment systems clearly lies with the supplier or the installer. However, Redvision is keen that accidents are avoided in the first place.”
