Dakota Alert is the leading manufacturer of wireless alert products like wireless driveway alarms and motion sensors. Keep an eye on buildings throughout your property or just be alerted if someone is coming up your driveway - you can be completely aware of any presence on your property.

The Dakota Alert 4000 wireless series communicates up to 1 mile between the sensor and the receiver and the hard-wired vehicle sensors can detect motion and vibrations from nearby vehicles up to 12 feet away.

• One-mile wireless range between the sensor and receiver. The sensor detects vehicles only. No false signals from deer or other large animals. The probe only detects metal.
• Easy installation - Up to 16 sensors can be paired with one receiver or an unlimited number of receivers can be paired to one sensor. Simple code-learning technology means you can have this set up in minutes. The receiver will play one of 16 tunes whenever a signal is received.
• Longest wireless range in its class - One mile wireless range is much greater than other products that claim ¼ mile or ½ mile. The long range means the radio signal is more likely to get through to the receiver.
• Ultra-reliable battery operation - The sensor operates on three CR-123 batteries (included). The batteries will typically last a year or more before they need to be changed. No need to worry about a solar panel not charging. The battery works day or night.
• Four different volume levels to give you just the right sound level for your application.
• Includes 1 receiver.

Operating Temperature Range: -30°F to 120°F
