Encountered issues finding an appropriate POE speaker to connect to existing POE system. Evidently Audio Over Ethernet (AOE) is a relatively novel concept with only one company, Audionate, producing accessible speaker systems. These systems are intended for professional audio use and because of this, AOE speakers are fairly expensive ($400+) and require an almost as expensive POE injector/amplifier to operate.
Meet with Todd to discuss alternatives. Concluded that costs for a POE speaker are too high and that an IP speaker would cause too much signal interference with the telescope. The only worthy alternative being connecting an off the shelf outdoor speaker to the local server through an AV cable. This will cause moderate levels of interference however and requires discussion with Kerry before moving forward.
Talked with Kerry about new speaker idea. He said that interference isn't going to be an issue and he has his own system of speakers that we can use for the task. From here, the plan is to find a way to take the audio signal from the AV cable and plug it into the existing Amcrest software.
Speaker audio are now controlled by the Amcrest client on the local server. Power will need to be provided by local wall outlet. From this point on, speakers and cameras are integrated as one system.
Add an outdoor audio speaker to the control room allowing live or canned messages to be played automatically or via the Admin Phone App video screen. If Kerry sees someone climbing over the fence, he could give an audio warning by pressing a button. Another button (existing) can stow the telescope.
Speaker system can be be integrated into the existing PoE Camera System and controlled by the NVR.
