Front and backup camera on 1 monitor with split view



does anyone here know a system with 2 (waterproof and night vision) cameras (front + rear) hard-wired to a monitor with a permanent split view of both cameras (not connected to the reverse lights)?

Wireless would have been a must but I read too often bluetooth connection will interfere, giving lost connection screens. Since I use my bluetooth headset all the time, I need either a wire connection or a reliable wirless connection.
