Things to Consider Before Choosing GPS Trackers For Private Investigators
There are different types of GPS devices in the market. But not every one of them is for you. Before choosing anyone, you should consider these factors.
Portable or Hardwired?
There are two kinds of GPS trackers: portable and hardwired. Portable GPS trackers are best for hidden tracking for private investigators because they’re easy to attach and remove when the job is done. Hardwired GPS trackers require an expert to install and remove, and they can’t be used on things like bags or suitcases.
Product Dimensions
Using a small, lightweight GPS tracker is essential if you're a private investigator and need to track someone without being noticed. There are many options which are tiny enough to fit in your hand, making them easy to hide for discreet tracking.
Battery Life
Can you know exactly how long a case will last? Probably not. Imagine you're so close to getting crucial evidence, and the GPS tracker stops sending updates because its battery died. That would be frustrating. To avoid this, private investigators should choose a GPS tracker with a strong battery life to ensure it works throughout the case.
Installation Process
You will have a fraction of a second to install a GPS tracker on your target's vehicle or belongings. A GPS tracker with a lengthy installation process can ruin your time, and you will never be able to put it on their car. Therefore, you should purchase a GPS tracker with a simple installation process.
For this reason, you should choose a GPS tracker with a built-in magnet or magnetic case. This allows you to attach it under the car in just a few minutes, making installation quick and easy.
Real-time Updates
As a private investigator, you want to stay updated with your target's location 24/7. And for this, you have to look for a GPS tracker with real-time location updates. It will help you monitor your target in real-time, and you won't miss a second of their location.
Coverage
Another significant factor is coverage. As a detective, you should look for a GPS device with worldwide coverage. Why? As it will help you to stay updated about your target's location. No matter where they go or in which country.
Connectivity
The GPS device accumulates the data and uploads it to the cloud storage through which the user can access the location. The whole process is a time-consuming one. With slower networks such as 2G or 3G, location updates get delayed. As a private investigator, you should always look for a GPS tracker with better connectivity.
Mapping
You should also consider the mapping feature of the GPS solution. An ideal solution will help you to view the location from different views.
