Description
Driveway Alert Kit with Portable Receiver
The ERA-DSVPRX driveway alert kit is built from two Safeguard Supply ERA Series components: the ERA-DSTX wireless driveway sensor and the ERA-VPRX portable vibrating receiver. Together they provide a driveway alert system that detects movement at the drive and notifies staff carrying the receiver up to 4,000 feet away in line-of-sight conditions. This is useful for long driveways and larger properties where a fixed chime in one room is not enough to cover all staff.
The driveway alert sensor mounts outdoors near the drive and is powered by a 9V battery, while the receiver is a compact, battery-powered unit with a clip for belt or pocket use. When motion is detected, the ERA-VPRX can sound a tone, vibrate, illuminate its backlit display, or use a combination of these options depending on configuration.
ERA-DSTX Outdoor Driveway Motion Sensor
The ERA-DSTX is the driveway alert sensor in the kit. It is a passive infrared (PIR) motion detector designed to monitor driveways, lanes, and approach areas. The sensor looks for the heat signature of moving vehicles or people crossing its field of view. When it sees motion in the detection zone, it sends a radio signal to the paired ERA-VPRX portable receiver.
The ERA-DSTX includes a range selector that sets the maximum detection distance. The low setting covers up to around 25 feet, the medium setting extends coverage to about 50 feet, and the high setting covers up to roughly 100 feet. This allows the detection zone to be tailored to the driveway layout so that the sensor watches the intended section of drive without reaching out unnecessarily into public roads or distant areas.
- Detection method: outdoor passive infrared motion sensing for vehicles and people.
- Selectable detection ranges: low up to 25 ft, medium up to 50 ft, high up to 100 ft.
- Wireless range to receiver: up to 4,000 ft line-of-sight under favorable conditions.
- Power source: 9V alkaline battery.
- Approximate housing size: 4.5″ H x 3″ W x 2.25″ D.
- Operating temperature range: roughly -30°F to 120°F.
- Radio frequency: 433 MHz.
Driveway Sensor Mounting and Adjustment
For a typical driveway alert installation, the ERA-DSTX is mounted on a solid support such as a wooden post, fence, or tree. Mounting height is usually around three to four feet above ground, with the sensor located about twenty feet back from the edge of the drive and aimed across the lane. Pointing across the drive lets the sensor see sideways motion as vehicles or people cross the beam, which produces a more reliable trigger than aiming directly down the driveway.
The sensor body should be secure so it does not move in the wind, and metal posts are avoided when possible to minimize interference. The internal filter setting and reset time can be adjusted using internal switches: the outdoor filter helps ignore small movements such as leaves, while the reset time can be set to 10 seconds or 120 seconds between driveway alert activations. Installers typically walk or drive through the detection area several times while adjusting these settings to confirm that the driveway alert triggers only when and where it should.
- Recommended mounting height: about 3–4 ft above ground level.
- Typical placement: approximately 20 ft from the edge of the driveway, aimed across the lane.
- Mounting surfaces: rigid wooden posts, fences, or trees; avoid flexible supports and exposed metal surfaces.
- Settings: internal jumpers for range, outdoor filter, and reset interval.
ERA-VPRX Portable Driveway Alert Receiver
The ERA-VPRX is a portable receiver designed for users who need to move around a site while still receiving driveway alerts. It is powered by a rechargeable lithium-ion battery and includes a charging cable and wall adapter. At full charge, the receiver typically offers about six to seven days of standby time, depending on how often it is triggered.
The receiver provides three alert modes: sound only, vibration only, or sound and vibration together. It offers four volume levels, with the highest setting rated around 80 dB, and supports multiple melodies so different transmitters can be given unique tones. A backlit display provides visual indication when an alert is received and also shows basic status information.
- Alert modes: sound only, vibration only, or sound plus vibration.
- Volume: four levels up to roughly 80 dB.
- Wireless range: up to 4,000 ft from ERA transmitters in line-of-sight conditions.
- Power: rechargeable lithium-ion battery with charging cable and brick included.
- Standby time: approximately 6–7 days per charge, usage dependent.
- Transmitter capacity: supports pairing with up to 16 ERA transmitters or sensors.
- Dimensions: about 4.0″ H x 1.5″ W x 0.75″ D.
- Operating temperature: approximately -30°F to 120°F.
Driveway Alerts for Mobile Staff
In use, the ERA-DSTX monitors the driveway for activity, and the ERA-VPRX rides on a belt clip or in a pocket. When a vehicle or person enters the detection zone and triggers the driveway sensor, the receiver immediately alerts the user through vibration, sound, or both. This arrangement works well in settings such as shops, warehouses, or homes where people regularly move between rooms or buildings but still need to know when someone arrives at the drive.
Because the receiver can pair with up to 16 transmitters, the ERA-DSVPRX driveway alert kit can be expanded over time. Additional driveway sensors, door transmitters, or indoor motion sensors in the ERA family can be added and assigned different melodies or zones, allowing staff to identify whether a driveway, front door, or secondary entrance caused the alert just by listening to the tone and checking the display.
- Typical applications: long residential driveways, shop or warehouse approaches, gated entries, and service lanes.
- User type: staff who need driveway alerts while moving around a property rather than staying near a fixed chime.
- Expansion: pair additional ERA sensors to cover doors, gates, and interior zones under the same portable receiver.
ERA Series Compatibility and Expansion
Both the ERA-DSTX and ERA-VPRX are part of the Safeguard Supply ERA Series. Any ERA transmitter—such as push buttons, universal transmitters, interior PIR sensors, or additional driveway sensors—can be programmed to the ERA-VPRX. Each transmitter can be assigned its own melody, which helps distinguish between different types of alerts. There is flexibility to use the ERA-DSTX driveway alert sensor with other ERA receivers in addition to the portable unit, so a single driveway sensor can notify a desktop or plug-in receiver and the portable receiver at the same time if needed.
This modular approach makes the ERA-DSVPRX kit a starting point for a broader driveway and entrance alert system, with the ability to add more transmitters and receivers as site needs change.
- Series: part of the Safeguard Supply ERA long-range wireless platform.
- Compatible transmitters: ERA-DSTX and other ERA Series push buttons and sensors.
- Compatible receivers: ERA-VPRX as well as other ERA receivers, if added separately.
