In-case where extreme high security is desired such as prisons, restricted government research centers and other restricted zones, anti-climb or 358 fence can be installed. As the name suggests, in this fence due to the small spacing between the mesh it is practically impossible for anyone to climb. These fences are normally seen in Australian prisons.
To add additional security, normally electric fences are installed on top of the fence or compound wall to deter criminals from entering inside the property. The electric fences that are installed are generally SMART and use IoT technologies to alert the users whenever there is any intrusion via a gsm alert or CCTV activation.
