Officer safety and the need to record traffic stops to be used primarily as evidence in the courtroom are being called the main reasons behind a technology upgrade for the Osage Beach Department of Public Safety. The board of aldermen, last night, gave its approval to the purchase of 16 in-car video systems complete with wireless mics, server and laptop software. The new equipment, according to Chief Todd Davis, replaces aging systems currently used by the department which have been experiencing multiple problems. The board also approved the purchase of half-a-dozen mobile data computers including associated docking systems and power supplies with four to be used by the PD and the other two by the city ambulance service. Total combined cost of the upgrades right about 124-thousand dollars.
