2. Listening Devices

Voice-activated audio recorders are the second most popular types of spy equipment used by private detective companies. How voice-activated recording and listening devices work is simple:

  1. Hide digital voice recorders in the target’s vehicles or home
  2. Voice recorders will stay inactive until the sound is detected where they will then begin recording 
  3. Learn what someone is saying when you are not around

Voice-activated recording systems are the ideal spy gear for investigations that include infidelity, spousal abuse, or child custody cases. 

3. Bug Detector

Best Bug Detection Device 2022

Are you worried that an ex-partner has a hidden nanny camera in your home and remote control to see everything you are doing in your residence? Maybe you suspect your employer might be using security equipment and tools to spy on you while you are on the job. If you have conducted surveillance sweeps at a basic level, it is important to utilize bug detection equipment if you really want to reinforce your privacy. Hidden camera detector devices can pick up GPS and RF signals, allowing you to instantly find any type of spy equipment that could be monitoring you. We would highly recommend anyone who stays at an Airbnb invest in a bug and camera detector.  

4. Hidden Spy Cameras

Best Hidden Camera 2022

In a recent article in The Atlantic, journalist and author Sidney Fussell wrote about how spy cameras and hidden covert cameras in household items such as smoke detectors were being used in Airbnbs to spy on guests. Although these types of surveillance applications are certainly nefarious at best, those same tools designed to capture videos and photos can be utilized at home or in the workplace for good causes. For example, a hidden camera in the workplace can be used for security purposes if a crime is committed on the job such as an employee stealing from an employer. At home, remote-control video camera solutions (nanny cams) can be used to record babysitters who could be abusing children.

5. Phone Spy Software

Bluetooth Cell Phone Call Recording Device, iPhone And Android Mobile Recorder

Spyware and investigative apps are another way people can find out the truth and bust a cheating partner. The one drawback of investigative apps is that they need to be installed on an iPhone or Android device, and that can be challenging if your partner is indeed having an affair. But if you are lucky enough to gain access to their mobile device, you should consider using a spyware app if you have ever asked the following questions:

  • Is there an app where you can see your spouse’s text messages?
  • How can my wife read my text messages?
  • How to spy on your spouse phone without them knowing

Be Your Own Private Detective

Why should you consider investing in electronic devices or pieces of equipment designed for surveillance over just hiring an expert who specializes in surveillance techniques? The answer is money. Hiring a private investigator to set up covert spy cameras or audio bugs can be expensive. However, when you invest in a spy pen, real time GPS, security cam, or other surveillance product, you can conduct the investigation yourself at a fraction of the cost! In fact, hidden devices to track vehicles can be purchased for less than $100 and come with free technical support so there will be someone available to help you if you need that assistance. This makes it easy to be your own private detective! 


What Equipment Does A Private Investigator Use?

Private investigator equipment has never been easier to access or more affordable than it is today. This equipment comes in the form of products such as GPS tracking devices, audio recorders, or spy cameras that require zero security training to operate. In fact, some of the spy gear is even backed with free technical support to help you use the private investigator equipment! Therefore, if you want to catch a cheating spouse or need to conduct a surveillance operation, we recommend you check out the 5 best surveillance devices mentioned above that are all less than $100! 

How Can I Know If My Ex Hired Private Detective To Spy On Me?

Are you worried your ex-husband or ex-wife is tracking you? Maybe they even hired a professional to spy on you? If you so, here are some common signs that a cheating partner may be being followed by a private detective:

  • Observing a person or vehicle following you repeatedly
  • Unexpected phone calls or hang-ups
  • Presence of unusual technology (such as cameras or recording equipment)
  • Unusual or increased attention to their phone or computer activities
  • Sudden changes in their behavior, such as increased aggression or hostility

Can A Private Investigator Tap A Cell Phone?

Absolutely not! If you are worried your ex-husband or ex-wife has hired someone to tap your cell phone you should know that private investigators cannot legally bug cell phones. Wiretapping is illegal and requires a warrant from a court of law. Unlawful interception of electronic communications is a serious crime and violators can face penalties including fines and imprisonment.
