Audio Surveillance Devices

You can use audio surveillance equipment for a variety of tasks, from evidence gathering and security to recording useful information for personal use. Audio surveillance adds a layer of protection, helping you detect disturbances that might not be immediately obvious through security cameras and video surveillance alone. You can achieve all of these goals with various devices, and it's important to know the pros and cons of each option.


Types of Surveillance Microphones

From base stations to all-weather microphones, find surveillance mics designed for your needs.

Base Stations

Base stations can connect to multiple microphones to record audio over a larger area. They can record sound with a DVR system, which reduces the need for additional storage. Base stations can be connected phone lines and other types of audio inputs. 

Voice Activated Recording Devices

If you'd like to record conversations and phone calls, voice-activated recording devices are effective options. These devices remain in standby mode until they detect voices, at which point they begin recording. Some variants connect to phone lines and only power up when your phone line is active.

Outdoor Microphones

Use outdoor microphones for recording outside of your facility or home. With special weatherproof shells, outdoor mics can stand up to the harshest elements while still delivering clear audio recordings.

Detective Audio

Covert recording devices, also known as detective audio gear, often take the form of innocuous objects such as pens, necklaces, and USB drives. The advantage of covert devices is that only you are aware that the audio recording is in process, making them ideal for gathering evidence. 


Portable vs. Stationary Recording

When choosing your audio recording equipment, it's important to consider whether you need portable or stationary devices. Stationary devices can connect directly to a power supply, negating the need to replace batteries. You can also plan ahead of time, placing multiple microphones for a much wider coverage area. If you're recording in one place, then stationary devices are ideal.

On the other hand, portable recording devices offer much-needed flexibility, and you can take them with you wherever you go. If you plan on recording a conversation and you're not sure where it will take place, then portable devices are the best option.
