Intrusion detection for dredger

A dredging boat vandalised near Scunthorpe is now being protected by a GSM based intrusion detection system, linked to an alarm receiving centre (ARC).

Ebsford Environmental was working to remove silt along the Bottesford Beck tributary that feeds into the River Trent for four weeks as part of flood prevention. While the dredging boat was moored overnight, vandals smashed lights and temperature gauges. Although it did not stop the job being finished, it was cost time and money to repair.

Dean Bolton, Managing Director at local installer Eyewatch Security, was approached by Ebsford Environmental. Bolton recommended a VX402 GSM system that comprises an OPTEX outdoor passive infra-red (PIR) detector that includes a GSM transmission module developed by TAD Electronics, monitored remotely at Eyewatch’s ARC.

Nick Oxley, Site Foreman for Ebsford Environmental says: “Although the damage was fairly minor, it was still a huge inconvenience to take the boat out of action to be repaired. And who knows, the damage could be worse next time. After the detector was installed we did not have any further issues, there was no more damage and we also did not have any false alarms.” 

Dean Bolton says that large parts of Scunthorpe are now protected by OPTEX detectors: “We specify OPTEX detectors on most sites we work on due to their reliability and solid design. As in this situation, the detector worked as an excellent deterrent and no further damage was done to the dredging boat.”

Ricky Miwa, Managing Director of OPTEX Europe adds that the sensor with the GSM transmission provides a solution to monitor intrusion detection in remote or isolated sites. “This outdoor sensor features small animal immunity which drastically reduces unwanted alarms triggered by wildlife, which is an important feature when protecting a boat moored on a river bank.”
