Magnetometer
For many years magnetic surveys have been conducted around the globe. In the past it tended to be the oil industries that would use items like a Magnetometer to check for variations in the Earth`s magnetic field. The surveys of old were inclined to rely on old technology within the machinery. This did the job but it tended to be rather slow. In recent times modern advances in a portable Magnetometer have now made it useful for a host of other applications. Magnetic surveys can now be conducted for a host of reasons. On land where steel drums have been buried in the past this type of equipment can be used to quickly establish their exact whereabouts. Similarly one of the Magnetometers can be used to locate underground storage tanks that have long since been abandoned. On site surveys where disused mine sshafts need to be found a Magnetometer is the equipment to use. They`ve been around for time but the recent advances in the speed of operation of portable geophysical equipment like a Magnetometer now makes them useful for a wide range of environmental applications. Such devices can be purchased or then can even be hired through sales and rental specialists.

Cctv Cameras
Walk through a city centre and you every step could be closely monitored by a set of electronic eyes. In large cities Cctv Cameras are in operation monitoring the activities of people on the street. Camera operators can be called into action to trail suspects and they can zoom in and out when they are required and capture footage on film that can later be used in evidence. From a security perspective Ccctv Cameras are invaluable as they can remotely monitor a wide variety of sites. They can be placed on the inside or the outside of a building and keep their beady eyes on all the comings and goings. Complete systems can be bought that will be able to monitor a host of on-site locations and solo cameras can be fitted to monitor private homes or garages. By design the Cctv Cameras are highly discreet and the footage they capture is of excellent quality. It wasn`t always like this though because early systems tended to be rather poor. However, with advances in technology the new ranges of Cctv Cameras provide pin-sharp images and this can often prove to be essential when evidence is needed in a court of law.
