Bergen, Hudson & Passaic — investigated by people who know the territory

Cop Call is a New Jersey private investigation firm based in Montvale, in the heart of Bergen County. We focus on Northern New Jersey — Bergen, Hudson, and Passaic counties, with coverage extending into Essex and Morris — because investigations go better when the investigator knows the ground. We work cases from Hackensack and Paramus to Hoboken and Jersey City, and from Clifton and Paterson out to the towns along the county lines.


We are not a national directory that sells your inquiry to the nearest bidder. When you call (201) 345-2124, you reach a licensed investigator who works here.

Private investigation services across Northern NJ

Every engagement is handled by a licensed investigator and documented to court-admissible standards. These are the services Northern New Jersey clients and attorneys retain us for most often.

Surveillance.

Discreet, court-admissible physical surveillance with high-resolution photo and video documentation — for personal, family-law, and corporate matters.

Infidelity Investigations

When you need to know the truth about a spouse or partner — documented discreetly, lawfully, and in a form that holds up if you decide to act on it.

Child Custody Investigations

Court-admissible documentation for custody and parenting-time matters, prepared to the standard New Jersey family courts expect.

Background Checks

Source-of-truth background investigations for employers, attorneys, landlords, and individuals — far beyond what online lookup tools deliver.

Asset Searches

Locating and documenting assets for litigation support, judgment recovery, divorce, and due diligence.

Salary Investigations

Verifying income and employment for support, litigation, and due-diligence matters where an accurate earnings picture matters.

For New Jersey attorneys and their clients

Family-law and litigation attorneys across Northern New Jersey refer their clients to Cop Call because our work is built to survive scrutiny. Every observation is timestamped, every photograph carries its metadata, and every chain of custody is documented from the field to the final report — and our investigators are available to testify as fact witnesses when a matter proceeds to court.


Whether you’re an attorney building a case or an individual who simply needs to know, the standard is the same: lawful methods, careful documentation, and complete discretion. If you have an attorney, we coordinate with them. If you don’t yet, your final report will be ready for the one you hire.
