Which system topology is best for retrofitting an existing building with an access control system?

The choice of IP Addressable control panels and leveraging the customer's existing network is ideal for retrofitting an existing building with an access control system for several reasons.

First, utilizing the existing network infrastructure helps to minimize costs associated with installation and equipment since it avoids the need to lay new cables specifically for the access control system. This is particularly advantageous in retrofitting projects, as physical modifications to the building can often be disruptive and expensive.

Second, IP Addressable control panels offer greater flexibility and scalability. They can integrate seamlessly with other systems such as surveillance cameras and alarms, allowing for a more holistic approach to security management without the need for extensive hardware upgrades.

Additionally, this approach supports remote management and monitoring through software, enhancing the overall usability of the system. Users can access and manage the control panel from anywhere, which is often a requirement in modern security solutions.

Overall, this choice maximizes the use of existing resources while providing an advanced and efficient control system suited for contemporary security needs, making it the best option for retrofitting.
