The Resolution Products RE204 is a wireless driveway sensor designed to detect vehicles entering a secured premise. It is compatible with Honeywell and 2GIG alarm systems. The RE204 uses a sensor to detect a change in the earth's magnetic field. Vehicles alter the local magnetic field around them. Therefore when a car passes down a driveway it will shift the magnetic field and trip the sensor. This means no false alarms from animals, leaves, or anything else blowing in the wind; unlike passive infrared motion detectors which tend to cause false alarms in an outdoor environment. Ideally the device should be installed at least 24 feet from the street to avoid false alarms; no more than 2/3 the maximum wireless range of the RF receiver to ensure reliable RF connectivity; and within 12 feet of the target vehicle or center of the driveway.

This is a great product for homeowners or business owners looking to setup local and remote alerts when vehicles enter their property. Honeywell and 2GIG alarm systems can be configured to setup local keypad chime and voice announcements as well as text and email alerts via Alarmnet or Yes you can get a text anytime a vehicle enters your driveway!

The RE204 is a fixed dome sensor (5.1 inches x 3.8 inches) that is fully weatherproof and functional between temperatures of 0F and 120F. The unit is powered by a C-Cell Energizer battery. Battery life should be anywhere between 3 to 5 years. The positive (+) should be opposite the springs. Keep in mind, that extreme temperature fluctuations and extreme humidity can adversely affect the function of this unit and the battery life.

This device comes with a right angle assembly that can be mounted on a non-metallic stake or pole at around door-handle height. The sturdier the better to reduce false alarms. There is a sensitivity jumper pin located on the board. You can choose between low, medium and high sensitivity levels which equate to short, medium and extended catch radius distances. Keep in mind, that the short catch radius is more likely to miss a passing vehicle and the extended catch radius is more likely to false trip. We always recommend medium sensitivity if possible.

The RE204 will auto-enroll into your alarm panel by placing your system in learning mode and inserting the battery. It should automatically enroll the serial and loop number. If you prefer to manually enroll it, assign the zone to loop 2.

**Please note: Similar to the transmission lockout feature on the Honeywell wireless motions, this device has a 30 second lockout after it is tripped. So wait around 40 seconds between detection tests.**

Great Driveway Sensor!

The Resolution Products RE204 is a 345 MHz driveway sensor that works with Honeywell and 2GIG Systems that support wireless sensors. It is used for letting the system know when a vehicle has entered its coverage area. The device works by detecting the change in the Earth's magnetic field that occurs when a vehicle comes into a specific area. A car or truck entering the sensor's coverage area will shift the magnetic field around it and activate the sensor. We think that the sensor is perfect if you want to know when a vehicle has entered a specific area. We give the RE204 a 5 Star rating.

There are many things we like about the RE204. Its detection method means that only vehicles will set it off. You won't experience false alarms due to people or animals coming within the sensor's coverage area. This is great if you want to know specifically when a vehicle has entered the coverage area. The device is fully weatherproof, so you won't need to worry about leaving it outside. The sensor has a pretty long battery life, as it uses a single C battery that gets three (3) to five (5) years on average. The device offers three (3) different sensitivity levels, which are low, medium, and high.

There are some downsides to consider when using the RE204. For one, it is discontinued, and you can no longer purchase new models from Alarm Grid. The device should not be used within 24 feet of the street because of the possibility of false alarms caused by passing vehicles. The sensor can only be used to detect vehicles. If you want to use it to detect people or animals, then it will not work for you. However, this is a positive if you are only wanting it to detect vehicles. Overall, we really like the RE204. It gets 5 Stars from us.

Good: No False Alarms By People or Animals, Weatherproof, Long Battery Life, Three Sensitivity Settings

Bad: Should Not Be Used Within 24 Feet of the Street, Only Detects Vehicles

Bottom Line: 5 Stars
