Access Control Systems

An access control system is more than a passive alarm or a carefully placed security camera, it controls who can physically and logically access a company’s assets.

Keep Visitors and Employees Safer:

  • Provide Better Visitor Management – Tracking visitors via an automated visitor management system will provide greater security, more accurate records and reporting and instill a greater sense of visitor confidence.

Gunshot and aggressive voice detection systems

  • Gunshot and aggressive voice detection systems can integrate into surveillance and access control systems to provide immediate awareness of a threat. These systems can provide pre-event detection of an escalating situation and alert the appropriate respondents.

Secure and Limit Access to Sensitive Areas:

  • The entrance and exit doors to your premises, the parking lots and certain areas of the facility’s interior – data centers, employee only areas, and restrooms – can be made more secure by implementing the use of electronic keys, ID cards and even biometric identification techniques.


While most businesses can benefit from the implementation of a formal access control system; for some businesses, it is a must! These include:


  • Provide a secure environment for employees and better safeguards for physical inventory.

Healthcare Facilities

  • Adherence to data privacy rules and HIPPA policies, as well as general patient safety, has become of the utmost importance for any medical practice, and so healthcare facilities are some of the greatest beneficiaries for an access control system.

Businesses Housed in Multi-Tenant Buildings

  • Access control system help ensure the premises are accessible only to the employees, customers and visitors who are supposed to be there.

Small Businesses

  • Our well-designed access control system can provide big company level security at a very affordable price while also improving the quality of those over-worked employees lives considerably.

Electronic Security FAQs

What is an aggressive voice detection system?

An aggressive voice detection system is very unique from other types of audio detection and recording in that it does not actually record audio or spoken voice. It uses complex analytics to measure a distinct characteristic that occurs in the human vocal chords when someone becomes angry. The microphone becomes a sensor and not an actual recording device which allows it to be placed in environments where previously other types of detection could not be installed because of rights to privacy, such as school restrooms. We feel that this technology can help prevent confrontations from escalating to violence because respondents will be notified when hostile communication begins to take place.

How do I choose the correct camera for my application?

This in general is a comparatively difficult decision. Many aspects of the installation must be taken into consideration in order to obtain the correct performance that meets your requirements. We will work closely with your team to provide the best solution for your application.

Why do I have a clear sharp picture during the day and it is out of focus at night?

More than likely an incorrect camera was chosen for this application.

I have installed a new camera and lens why I am unable to obtain a sharp image?

There may be many reasons for this situation such as poor cabling or connections, incorrect lens, poor lens fitting, and dirty lens and/or housing. Our technicians have the training and experience to identify and correct the issue.
