When to Use Analog

Any time the audio devices will be added as an attachment to a security solution, like connecting to a recorder or integrating into an IP video solution, it is best to choose an analog microphone. Similarly, if the audio devices will be integrating into an analog appliance, like a VCR or NVR, an analog microphone is the best choice. Alternatively, when deploying standalone audio solutions or systems with one-way and two-way talkdown features, analog systems have the upper hand. When it comes to installation, analog mics are easy to install and compatible with most other hardware devices, like cameras and recorders. 

When to Use Digital IP

When it comes to IP audio, customization and the ability to add analytics software are some of the biggest differentiators. IP microphones allow integrators to have more control over the system’s sensitivity, interface and can be integrated with audio analytics software, like decibel-level threshold alarming. The microphone’s decibel-level threshold alarming can create alarms if a set decibel level is exceeded as well as trigger relay outputs to other security equipment, making them capable of operating independently or as part of a larger solution.  Additionally, IP microphones require less cabling, which can save integrators on installation times.
