Maximum security
Scalable options & Flexible solutions
Seamless integrations into existing security solutions
Easy Adaptability for future security integrations


We are known as access control specialists in Philadelphia that can upgrade your existing system or install brand new technology. If you have access control security systems in place among multiple locations, we can unify the systems for easy, centralized monitoring. Unifying multi-location access control systems allows for better organization in device monitoring and decreased risk of security gaps or oversight.

We also offer security system repair in the event your current security systems are malfunctioning. Sometimes a device goes offline due to human interference – like breaking a card reader – or because of an overdue software update. Other security companies may only install these systems and make you rely on another vendor for repair. Keystone works with security systems at all stages, from design and installation to service and repair, so you only need to trust one company to secure your business.


Another highly effective security solution we provide is perimeter detection. Using perimeter motion detectors in Philadelphia, we can help businesses stay alert of potential security threats.

Perimeter detection helps stop a threat to your business at the edge of your property. Motion detectors installed along fences or exterior walls can differentiate between humans and animals and alert your security team by text message or email of a potential security breach. In stopping a threat far from your business’s front door, you reduce the risk of a break-in or burglary.

Perimeter detection is one facet of a larger intrusion detection system. When integrated with other devices like glass-break sensors at windows, a door monitoring system, and infrared (IR) or light sensors, your business has greater protection and lower chance of a false alarm.

Integrating video surveillance with an intrusion detection or access control system improves overall security ten-fold. Security monitoring systems become much more valuable when they work together.

When installing Philadelphia surveillance cameras, the Keystone team will find the most effective locations to monitor traffic at your business, like key entry points, highly traveled areas like hallways, and outside rooms with sensitive information. These systems are so advanced, they are able to recognize faces and compare the information to a database, which could, for example, alert you to a blacklisted visitor or to an employee attempting to access an area that requires higher credentials.

For the retail store owner who is concerned about grainy images, Keystone has high-quality surveillance cameras that can help identify suspects. Images are clear and footage can be recorded in 1080p high definition. Some new technology can zoom 12 times and retain a clear picture, allowing you to capture suspicious activity from a distance.

Video surveillance also acts as a deterrent for most criminals. When they see a camera pointed directly at them, following their every move, they typically think twice about their actions.

These security solutions can also improve your production process and quality control.
