FAQ

Ensure that the microphone wiring connections match the instructions in the respective microphone’s user manual available on www.louroe.com, ensure that the correct recommended shielded cable has been used to wire the microphone and that the cable assembly is not routed near or around equipment that generates high electrical noise, such as fluorescent lights, electrical generators etc. Test the microphone audio with quality workstation pre-amplified speakers. If using inexpensive, subpar workstations speakers it is possible that the speakers are overloading causing the static/feedback issue.

In the case of our Mic Level Microphones, the IP camera supplying 1.8-4.5V will power the mic as well as provide the audio input signal.

For the best audio quality, a shielded cable is recommended. Most one-way audio applications require a 2-conductor shielded cable, 22 gauge with a 24 gauge drain wire. Most two-way audio applications require 2-conductor shielded, 20 gauge with a 22 gauge drain and 1 conductor unshielded, 20 gauge all in the same jacket. Unshielded cables such as CAT 5 and CAT 6 are not satisfactory for audio systems.

Normal Sensitivity = (0 dB @ 1,000W)

Low Sensitivity = (-6 dB @ 1,000W)

Line Level mics connected via audio adapters can increase up to 10dB.

Our products DO NOT have storage capabilities. You can connect them to storage devices via audio input.

An audio input is needed for each microphone connected. Multiple mics connected to one input will cause poor quality.  Audio mixing can be done with an RN-2 or MLA-4.

When connecting our products to an IP-based solution, audio can be listened to remotely.

Our microphones use external power supplies, camera power, PC, & PoE to supply voltage to our products depending on what microphone category is being used (line, mic, digital level).

Digifact microphones have an RJ45 to connect directly to PoE for power. Other mics such as Line Level can be connected to IF-PX which can provide voltage via PoE.

Omni-directional mics pick up audio 30’ in diameter circle while directional mics pick up audio 12’ from mic element. For every 10’ the mic is installed on a pole or ceiling, you lose 10’ audio distance circumference.

Microphones can be connected to a storage system via a base station, audio adapter, or connected directly to the audio input. When connecting audio to an IP-based camera audio, the signal will stream with video via the camera’s connection to PoE when the mic is connected to the audio input of the camera.

Typically, the workstation has an internal mic that once the audio is enabled and the camera is selected, the operator can talk down to whoever is within hearing distance.

When purchasing an Audio Monitoring Kit Louroe Electronics provides a microphone, base station or audio interface, power supply, and patch cables. The only additional parts needed would be a shielded cable.

If the audio solution doesn’t need recording and only needs live audio we have audio kits that don’t need to connect to NVR/NVR. Our microphones need to connect to an audio input for recording purposes. Can use a PC or camera audio in if NVR/NVR does not have input.

If the audio solution does not require recording and only needs live audio, we have audio kits that do not need to connect to cameras. Our microphones can be connected to storage devices such as a NVR or NVR if the camera does not have an audio input.

If there is not a need for recording and only live audio is needed, Louroe has audio kits that do not need to connect to cameras. Louroe offers base stations with built-in speakers for live audio.

Check the Manufacturer’s Datasheet on the specific model camera selected, which will list the type of audio that their camera will accept.

Yes, you can use a Central Power Supply, but be sure to budget 100mA (500mA) per microphone.

The recommended distance for Mic Level Mics is 20’ and all Mic Level microphones come with a 20’ 3.5mm stereo cable. For Line Level, there is 1000’ distance restriction.

The datasheet of the IP Camera Data Sheet will identify audio input.

The recommended distance is up to 1000’ from a base station or interface device.
