Enhance Your Building Access Control

Learn how infinias' powerful Anti-Passback and Anti-Tailgating features can prevent common sources of unauthorized access

Security is a top priority for every type of business, including businesses in in Chico, CA. Unauthorized access gained through various entry points puts employees at risk of physical harm and inventory at risk from theft. infinias Intelli-M Access access control management software is equipped with both Anti-Passback and Anti-Tailgating features that help prevent unauthorized entry to designated areas and enhance security at building access points.


Anti-Passback is an access control security measure that prevents a cardholder from passing his or her access card to an individual behind them, and allowing them to gain access into a secured zone.

There are two traditional methods for preventing this type of security breach: Local Anti-Passback and Network Anti-Passback.

Local Anti-Passback

Local Anti-Passback is intended for single door access only. It prevents successive swipes by a cardholder into a zone, within an hour. The hour time limit is hard coded on the controller and cannot be modified.

Network Anti-Passback

Network Anti-Passback is intended to work across multiple doors or turnstiles. For example, if there are five turnstiles that allow access into a zone, the rule will be applied to all five turnstiles. This prevents a cardholder from entering 'Turnstile 1,' walking down to 'Turnstile 3' and passing back his or her card. This method will prevent successive card swipes by a cardholder into a zone, within an hour.

Anti-Passback establishes a specific sequence in which access cards must be used in order for the system to grant entry. It is commonly used at access points such as parking gates, fitness facilities and employee entrance doors.


The term "tailgating" refers to instances when one person swipes their access card and another person or vehicle enters at the same time by following them closely (tailgating them) through the entry point. Anti-Tailgating is an access control security measure that will not allow a cardholder to exit a zone that they never entered as a valid credentialed user.

Tailgating, also known as piggybacking, through an entrance or access control point poses a significant security risk by leaving buildings vulnerable to theft and vandalism, and by putting people at risk of bodily harm. Authorized employees are easily followed through a door without their knowledge. They may even hold the door open for someone behind them out of politeness; however, this common courtesy enables tailgating.

What Our Customers Say

"I had the Alibi system installed several years ago. It has functioned flawlessly. The image quality is exellent both night and day and in all weather conditions. I particularly like the replay (which can be set at various speeds) and zoom functions of the system. Tech support from Crimefreeliving has been excellent. I have received quick responses to questions, and timely home visits — as when I changed IP carriers and my Alibi system needed to be reset. I have recommended Crimefreeliving to several friends."


"As a small business owner here in Chico we definitely saw the need for video surveillance. After expressing our needs and concerns Tim did an excellent job getting us set up with the set up with the appropriate equipment. He really took the time to address our concerns in a very friendly, professional and knowledgeable manner. I highly recommend Tim for all of your business and residential video surveillance needs."

Ron H., Owner/Auto Doctor

"I have to say I love having my security cameras at my home. Tim Truby did a wonderful job of installing the five cameras. He is very neat and cleaned everything up after the installation. He explained to me how to operate the monitor, my phone and IPad. However, I have had to call Tim because I'm not tech savvy and forget what he has told me. He usually just helps me over the phone and then all is well. I'm 80 years old and enjoy the comfort of knowing I have these security cameras."


"Tim Truby designed and installed a 32 camera system for us here at the Butte County Mosquito and Vector Control District. We had received several other quotes from security system vendors, but Tim’s quote was the least expensive. Tim also installed the system quickly and has always been available when we needed him. We are very happy with our security camera system and we can highly recommend Tim Truby for all of your surveillance system needs."

D. Weseman, Butte County Mosquito and Vector Control District

Crime Free Living updated our old video system with a new 16 Channel HD Alibi Video Security System. The old system had been added onto by different installers which resulted in a cabling mess. There were cables that worked and cables that went nowhere. It was a mess. Tim sorted it all out and installed cameras that are very clear. He also installed a monitor for our cashiers to watch hidden areas, a monitor to watch the entry door, and a monitor that allows employees to watch the outside parking and gas pump area. All work was done on time and very professional! Will always recommend Tim and Crime Free Living.

S. AM PM Chico Arco Station

"I had Tim install an Alibi Video Security System at my residence and a couple business locations. The remote view option is invaluable to absentee owners or anyone who travels a lot. The clarity and quality of the cameras have allowed for viewing employee theft. The evidence provided from the HD video cameras was fantastic! Tim was professional and provided extra value from his law enforcement background."

J. Folsom Arco Station

"Tim, I want to thank you again for doing such a fantastic job on installing a wireless IP security camera system at our dream home. The extra time that you took to hide wires, and install a clean, professional system is much appreciated. I still can’t believe the clarity, quality, and ease of use of this new system. I wished that I would have met you before our original inferior system was installed by another company. Now, whether I am at home, or monitoring the system from around the world, I know that my home and family are safe and sound."

John M.

"In April of 2017, my husband and I made a phone call to Crime Free Living that turned out to be a smart and wise decision. Amazingly, in just a few hours, Tim installed four Dome Security Cameras, weatherproof enclosures, and hooked up into our home a 23" Full HD Widescreen Security Monitor. Even more than his professional expertise was the time spent with us in making sure that this system was working correctly and properly installed on our phones so that anywhere in our travels we can monitor our new home in Magalia."

Tieka and Don S.

"I have been using Crime Free Living for the last couple years ar work and at home and I really recommend this product. Tim is a very good service provider. If he can't figure it out, he's got good tech support with the system that he offers."

Gary D.

"I have known Tim for over 10 years. To date, Time with Crime Free Living has installed two separate surveillance systems for my company. With each system, Tim has listened to my needs and custom dsigned surveillance systems for my specific needs and within my budget. The equipment used is always state of the art, the workmanship is top notch, and Tim is the example of trustworthy. I would recommend him for any job."
