Useful resources and must-have gadgets to help you conduct better investigations

Posted by Dawn Lomer on November 1st, 2016

Today’s investigators have at their fingertips a plethora of useful tools and resources, from software and smartphone apps to digital research resources, state-of-the-art communications technology and nifty spy gadgets.

But many of these are costly and require company budget approval or a large personal bank account.

Fortunately, there are thousands of free and cheap resources for investigators that can help you conduct your investigations more efficiently and effectively.

Here’s a collection of useful investigation tools and resources that are either free or close to it.

Tools for Planning Investigations


Organization apps

A well-conducted investigation starts as a well-planned investigation. An carefully laid out investigation plan can help you and your investigation stay on track.

Calendar and personal organization apps are essential for a time-crunched investigator. Some are free, some paid, and there are so many to choose from that there’s bound to be an app that offers everything you need.

 

1. Google Calendar

Because Google Calendar is linked to your Gmail account, you can seamlessly access your calendar anywhere and from any device. For extra convenience, events are automatically added from your Gmail to your Calendar.

To get the most out of these investigation tools, download our free Investigation Plan Template and start scheduling your interviews and tasks.

2. Calendly

A personal calendar can keep your investigation tasks and activities organized. The basic version of this one is free, or you can upgrade to add more calendars and functionality for as little as $8 per month. A quick glance shows you if you’ve got anything pressing today and you can send a link to others so that they can see your availability and book time with you.

 

Tools for Conducting Research

Conducting the right preliminary research sets up your investigation for success. Start your investigation off on the right foot with free (or cheap) tools that help you conduct effective research.


Open source intelligence (OSINT)

Online research is a must for any investigator in the 21st century. Open source intelligence (OSINT) provides you with information from publicly available sources. There are thousands of ways to use OSINT tools to get the information you need.

 

3. OSINT Tools

We’ve put together a list of more than 101 OSINT tools for investigators. There are tools for any type of search you want to conduct, whether that’s a person, social media and dating sites, images and video, online communities and blogs, classified listings, background checks, business sites, the deep web or even geolocation.

Keep these OSINT tools on hand with our OSINT Links for Investigators Cheat Sheet.

 

 

Capture online data

Using the Web for conducting research is the new norm, but there’s a risk associated with collecting data and information this way. When you do find what you’re looking for online, you’ll need to capture it before it’s been modified, hidden, or erased. Luckily, there are free tools for this.

 

4. Camstudio

Record all screen and audio activity that takes place on your computer and easily turn them into AVI video files that can be saved and shared. Camstudio is free for personal and professional use.

 

5. Screencast-o-Matic

Alternatively, Screencast-o-Matic captures your screen’s activity and, if you use your webcam, you can customize your video with narration. There are both free and pro options with varying features.


Digital forensics tools

You will likely need to perform some sort of digital forensics as part of your investigation research. There are dozens of tools to choose from, both paid and free, and one particularly helpful one-stop shop for digital forensics tools for investigators.

 

6. 4Discovery

On 4Discovery, the tools are “as-is” and free for both personal and professional use. 4Discovery offers different options to extract metadata (document history, usage, authors and contributors), look at USB history and much more.


Surveillance gadgets

When you’re conducting surveillance, there’s a lot to consider. You’re watching the subject, taking notes and trying not to be seen. Applications and software are becoming increasingly helpful, and with a couple of gadgets to take the load off, surveillance becomes a much less daunting task.

 

7. Reverse View Sunglasses

Spy Emporium sells aviator gold trim spy sunglasses that let you follow someone without walking behind them. They’ll never know they are being followed. This investigation tool is as helpful as it is stylish.

 

8. Dragon Dictation

Tap the button, start talking, and the app handles the rest. Voice to text transcribes your notes and comments for later use. Keep your eyes on the subject while Dragon Dictation takes notes for you.

 

9. VoiceFinger

Helps you to record what’s happening without taking your eyes off the subject. TopTenReviews awarded the VoiceFinger app the fifth spot in their Best Voice Recognition Software of 2017.

 

10. Dragon Anywhere

A professional, web-based product that you can access from your Android or iOS mobile device and share files using cloud-sharing services.


GPS and mapping apps

You had the perfect opportunity to survey or confront a subject but you missed it because you were unfamiliar with the area and got lost. Never miss the exit again with apps that offer things like turn-by-turn voice guidance and traffic details.

 

11. Google Maps

Access up-to-date maps and detailed location information. Use the street view to get a feel for an area before conducting surveillance so that you are familiar with the location.

 

12. Waze

Take Google Maps to the next level with location search, traffic details, and map navigation. Turn by turn voice guidance and automatic rerouting gets you there.

 

13. Layar

Layar is an augmented reality application that lets you add real time details and notes to wherever you go. Augmented reality is a newer, more advanced tool for investigators (actually, for everyone) and it can be a little tricky, but it has so much potential.

Tools for Managing Investigations 

Research and information collection doesn’t stop once the preliminary stages are complete. In fact, it’s important to keep digging throughout the entire investigation process in case something new and significant pops up.


Reminder and monitoring tools

Calendar apps are great, but monitoring tools take it to the next level. Set up reminders and the app sends you real-time updates and notifications on whatever topic or keyword you requested.

 

14. Google Alerts

Set up an alert on the subject’s name, nickname and alias to monitor what they’re up to and receive notifications when new results appear.

 

15. Mention

Pick a couple of keywords (names) to keep an eye on and Mention monitors the web and social networks. The app then sends alerts daily or weekly.


File sharing and collaboration

Investigators may need to share large documents to collaborate with others working on a case, and this can be a disaster without version control. In the absence of a good case management software solution, there are free tools for investigators to upload and send documents, write notes, make edits and track activities.

 

16. Dropbox

This software offers secure file sharing and storage solutions. Packages include Dropbox Basic for infrequent, basic investigations, and Dropbox Business with extra storage and enterprise-level support.

18. Google Docs

Like the other pieces of the Google suite, Google Docs are available anywhere, anytime. All of your documents save automatically as you type, so you’ll never fear a lost version again.

 

19. Google Sheets

Track budgets, schedules, expenses and other spreadsheet files with Google Sheets. This collaboration app works with Excel and offers an explore panel for overviews of data and informative summaries.

21. AxCrypt

This app offers strong encryption, password management and multilingual interfaces. For added convenience, AxCrypt lets you collaborate with others, store your files in the cloud and access your encrypted files from your phone.


Tracking evidence

Best practices dictate that investigators use a system for tracking physical evidence. Losing, mishandling, or tampering with a key piece of evidence can change the outcome of an investigation. Set up your own efficient tracking system to keep an eye on all those important pieces of evidence.

 

22. Chain of custody template

This free template can be used to document physical evidence, track who has accessed it, and record information about evidence disposal.

 

23. Cheap label maker

A cheap label can be used for identification. Label the evidence with subject names, case names, dates, or anything else that works for you.


Reasoning tools

Need some help reasoning out your theories during your investigation? You’ll need a tool that helps you think objectively and logically about all your collected information and hypotheses.

 

24. Open Source Analysis of Competing Hypotheses

This simple model helps you think about complex problems. If the investigation has you running mental laps, this will help you make well-reasoned, analytical judgements.
