摘要： A manhole security cover includes a manhole cover body comprising a non-metallic RF signal transmissive material. The manhole cover body is seatable on a manhole frame to cover a manhole opening. In the seated position, the first side is accessible from outside the manhole, the second side is disposed within the manhole, and the peripheral edge portion engages a manhole cover support surface on the manhole frame. A manhole cover tamper sensor is responsive to a predetermined movement of the manhole security cover body. A transmitter is operatively connected to the manhole cover tamper sensor and configured to generate a radio frequency manhole cover tamper signal when the manhole cover tamper sensor detects the predetermined movement of the manhole security cover body. An antenna is operatively coupled to the transmitter to radiate radio frequency energy through the manhole cover body to a receiver located outside of said manhole.

摘要： A security lock for a storage tank includes a lock ring configured for engaging an opening that provides access to the storage tank. A suitable mounting assembly is used to mount the lock ring to the opening. One or more obstructions are disposed within an inside (and/or outside) area of the lock ring. The one or more obstructions define one or more openings that are sized to allow storage tank contents to be introduced through the security lock while blocking pipes, tube or other implements that are larger than the openings so that such implements cannot be used for siphoning or otherwise removing the storage tank contents.
