Controlling vehicle access to a site can easily be achieved by one of the following methods. The controlling device can be operated by an intercom or one of the many reader technologies such as key fob, proximity card, keypad or even automatically by number plate recognition.

• Traffic Barriers are an effective and convenient means of controlling vehicle access to a site. Many sites choose barriers to control access because they are quick in operation, have an overt presence and are low in cost compared to other methods.
• Gates either new or existing can be automated to provide an access control system. They can also stop pedestrians entering the perimeter of a site without prior authorisation. They are generally slower in operation to barriers but this is not a problem if traffic flow rates are low.
• Rise and Fall Bollards can also be used to restrict vehicle access. These are very discreet and have minimum impact on their surroundings.
