We handle difficult surveillances and have a 99% success rate when it comes to providing results without getting caught.

All of ABI Security Group Private Investigators and Detectives keep detailed and accurate notes. At the end of the investigation, these are transcribed and typed into a cohesive and understandable final Case Report, complete with details, times, places. If we have done video taping or taken still photographs, these will be presented to you along with your written report.

Sometimes, circumstances make it uncomfortable for our clients to actually receive these reports because of fears that they may be located and viewed by the Subject of the investigation. We are happy to store all reports and investigative evidence gathered in our secure offices until they are needed for court or other purposes.

Technical Countermeasures & Bug Sweeps

When dealing with sensitive and proprietary information, it’s important to make every effort to ensure your privacy. Unfortunately, those with a motive to steal this confidential information are often clever and can hide listening devices and surveillance equipment in places where the layperson simply doesn’t think to look. That’s where a team of licensed private investigators steps in.

At ABI Security Group we take the privacy of our clients very seriously and are equipped to detect bugging devices as small as a dime. Our thorough bug sweep services are conducted using the most advanced countermeasure equipment available and leave no location or electronic systems un-inspected, so you can ensure that your home or place of business is indeed private. Our continuing education program provided by one of America’s top-rated countermeasure agencies ensures that our licensed private detectives keep up with the current technology.

If you suspect that your private or professional property has been bugged, call ABI Security Group. We also provide routine bug sweeps for clients in need of a higher level of protection.

Background Checks

ABI Security Group will help you design a customized, cost-effective background and employment screening solution.

Pre-employment Interviews

The best way to avoid issues with bad employees is to do proper screening on the front end. Allow us to know the characteristics you are looking for and we will use our interview skills to weed out those undesirable prospects. We can also develop secondary interviews that can shed light on the applicant’s work ethic and overall demeanor. This method will assure that the applicant is a good fit for your company and will lessen turnover.

Business Relationship Backgrounds

Picking one’s business partner is one of the most difficult things to do. We will go as in depth as you want into your partner’s history. Using our expert investigative skills to get to the truth so that you can move forward with confidence.

Residency History

Applicants will sometimes omit previous addresses to conceal criminal records. A Residency History Search compiles information from various sources, including voting, property records, as well as database information to arrive at a list of names and addresses associated with a specific Social Security Number. The locations of any unreported addresses can be searched for criminal records, providing a more thorough investigation.

Delaware County & Statewide Criminal Records

A County Criminal Records Search reports felony, misdemeanor, and pending charges in specific counties.

A Statewide Criminal Records Search includes information from all of the counties within a particular state. Investigating criminal records outside the county of residence is very important as these records may go undetected when a Statewide Criminal Records search is omitted. However, not all States offer Statewide searches but ABI Security can access individual county searches to make sure that no criminal record goes undetected.

Nationwide Sexual Offender Index

By law, any individual who has been convicted of a sexual offense must register with his/her state of residence as a sex offender. A Nationwide Sexual Offender Index Search reveals if an individual has been convicted of a sexual offense anywhere within the United States. This search, on the national and state level, is included in the Nationwide Database Criminal History Search.

Motor Vehicle Records

A Motor Vehicle Records Search offers a detailed description of an individual’s driving history. These searches are essential for individuals who drive company vehicles, rent vehicles in the organization’s name, or drive their personal vehicles while on the job.

Credit Reports

A Credit Report summarizes the financial obligations of an individual and catalogs an individual’s income range, debt to income ratio, public records, collections, current negative accounts, previous negative accounts, installment and revolving accounts, as well as address and employment information.

Workers’ Compensation Search & Surveillance

A Workers’ Compensation Search reduces the number of claims filed, and their associated expenses, by alerting employers and organizations to chronic abusers. This search is vital to organizations employing or staffing individuals who are involved in active, physical or labor intensive activities. Workers’ compensation records are available in most states.
