Wiring and Deployment Key Points
Top-floor equipment installation: As shown, the equipment in the top section must be placed inside an outdoor waterproof enclosure. When selecting a waterproof enclosure, it is recommended to search for "monitoring waterproof box" and prioritize metal material products, which have stronger durability and protection, and can better resist erosion from complex outdoor environments.
During cable connection, selecting the correct cable order is particularly important, and the specific requirements are as follows:
· Audio input signal: Microphone (Mic) and MicG (Microphone GND);
• Power connection: 8V power supply and GND (ground);
· Audio output signal: Speaker positive and negative terminals.
When transmitting the three sets of signals using Ethernet cables, it is necessary to use paired twisted-pair cables for connection. This maximizes the avoidance of signal interference. For example, when using orange Ethernet cable as the transmission line, the MicG signal must be connected to an orange and white cable. If randomly selected, this can easily cause signal interference, affecting the normal operation of the equipment.
