Businesses and housing estates will often have the need for entry control systems, making sure unauthorised people cannot gain access. This will usually mean the installation of a system to monitor who is coming in and out, and to allow authorised people safe, easy access.
Often security systems will come in the form of electric gates. The gates will swing open and shut, locking securely into place when closed. They can usually be operated by putting in a pin code, or by using a remote control. Some gates may open automatically to let in cars, though these will provide less of a security function.
Think about installing gates that also use a camera system to monitor traffic and people. This will give you added security and can also register car number plates to see who is going in and out. You will find gates like these operate as excellent entry control systems.
