The DCPA-4k Plus dominates with genuine 1-mile wireless range that penetrates walls and vegetation. Its buried probe detects vehicles only, eliminating false alarms from animals or swaying branches that plague motion sensors. The 50-foot direct burial cable lets you position the probe exactly where cars pass while keeping the transmitter protected.
Installation requires digging a narrow trench for the probe cable, but the payoff is precision detection you can rely on. The weatherproof housing survives extreme temperatures and moisture. Pair multiple sensors to one receiver for complete property coverage. This is professional-grade security without the monthly fees.
