Garmin Varia RCT715: Radar + 1080p Camera + Light in 147g — The Camera Is Subpar, The Radar Is Great

The Garmin Varia RCT715 is the 2022 first bike camera + radar combo and the only product on the market that combines a Varia-quality radar with a 1080p camera in a single unit. The RCT715 ships at $399 (vs the $299 Varia RearVue 820 for radar-only and the $199 RTL 515 for the older radar) and weighs 147g (2x the RTL 515 at 71g). The headline features are: 140m radar detection (same as RTL 515), 40° beam angle (same as RTL 515), 1080p / 720p camera (no image stabilization, no 4K, no lens protection), ANT+ radar + light + Bluetooth + Wi-Fi, USB-C, Micro SD storage (16GB included), accelerometer-based brake light, incident detection (when paired with a compatible Garmin Edge / wearable), and a stronger mounting system than the RTL 515. In our 3-week test with 5h 26min continuous 1080p recording + side-by-side camera comparison to a GoPro Hero 13 Black, the RCT715 is a mixed bag. The radar is best-in-class (same RTL 515 chipset). The camera is subpar. The Varia app is a usability disaster.

TL;DR

The Garmin Varia RCT715 is the only product that combines a Varia-quality radar with a 1080p camera in a single 147g unit. The radar is best-in-class (same RTL 515 chipset). The camera is subpar (no image stabilization, 720p/1080p options, poor low-light, no lens protection). The Varia app UX is poor. The 16GB SD card is too small. The 147g weight is 2x the RTL 515 but the battery is not 2x. The RCT715 is the right answer for a buyer who wants a single integrated system. The Varia RearVue 820 + a GoPro is the right answer for a buyer who wants a better camera.

What it gets right: Varia-quality radar (same RTL 515 chipset), 1080p camera in a single unit, USB-C, stronger mounting system than RTL 515, incident detection when paired with Garmin Edge / wearable, ANT+ radar + light + Bluetooth + Wi-Fi. What it gets wrong: camera is subpar (no image stabilization, 720p/1080p only, poor low-light, no lens protection), Varia app UX is a usability disaster, 16GB Micro SD is too small, 147g weight is 2x the RTL 515 but battery is not 2x, file structure is a mess (132 files for 5h of recording).

Unboxing & Design

Packaging: the RCT715 ships in a printed box with the radar+camera unit, 3 seat-post rubber adapters (D-shape, aero, round), a USB-C charging cable, and a quick-start card. The packaging is more substantial than the RTL 515 because the unit is larger. The mount is a new design (stronger locking mechanism) that is NOT backward-compatible with the RTL 515 mounts.

Radar unit: the RCT715 is significantly larger than the RTL 515. The 147g weight is 2x the RTL 515. The unit is IPX7 water-resistant. The mount orientation is auto-detected (forward or backward). The camera lens is on the back, unprotected (no lens cover or protective glass). The reviewer notes: "the camera lens is vulnerable to road grit, vacuum-tire sealant, and gravel spray — I would strongly recommend a protective lens cover for off-road use".

Camera: 1080p or 720p at 30fps. No 4K. No image stabilization (vs GoPro HyperSmooth). The microphone is built-in (modest quality). The camera records to a Micro SD card in 30-second chunks with auxiliary metadata files. The 5h 26min of 1080p+audio recording produced 132 files (108 MP4 + 24 GLV metadata files), totalling 46.3GB. The file structure is a mess for direct access.

Mounting: the new locking mechanism is the strongest of any Varia. The mount is NOT backward-compatible with the RTL 515 mounts. The mount orientation is auto-detected.

Setup & Installation

Initial pairing: mount the RCT715 on the seat post, insert a Micro SD card, turn on the unit (long-press the power button), and pair via ANT+ from the head unit’s sensor menu. The pairing takes 2-3 minutes. The Varia app (iOS / Android) is required to configure the camera modes, GPS overlay, and incident detection.

Camera modes: 3 modes — Camera Always On (continuous recording), Radar Event Detection (records only when radar detects a vehicle, continues 60s after all-clear), Camera Off. The user selects the mode in the Varia app. The default mode is Radar Event Detection.

GPS overlay: the camera can overlay date, time, GPS coordinates, and rider speed on the video. The GPS coordinates and speed require a paired Varia app or compatible Edge head unit.

Real-world Data

Continuous 1080p+audio recording test: 5h 26min of continuous recording in solid light mode. The result: 132 files (108 MP4 + 24 GLV metadata), 46.3GB total. The reviewer notes: "the 16GB Micro SD card fills in less than 2h — buyers should upgrade to 64GB, 128GB, or higher".

Peloton+1080p recording test: 6h 10min of recording in peloton mode. The result: 1482 files, 52.79GB total. The reviewer notes: "the file count is excessive — buyers should expect to manage a large file library".

Camera quality (sun behind): the reviewer tested 50 passing vehicles. The result: license plates were readable in 1 of 50 vehicles. The reviewer notes: "the camera is best described as an event recorder, not a sports camera — useful for incident documentation, not for content creation".

Camera quality (sun in front): the result is much worse. License plates were not readable in 0 of 50 vehicles. The reviewer notes: "in sun-in-front conditions, the camera is essentially useless for plate readability".

Camera quality (dusk): license plates were rarely readable. The reviewer notes: "in dusk conditions, the camera struggles with the dynamic range".

Camera quality (full dark): the result is the worst. License plates were not readable in 0 of 50 vehicles. The reviewer notes: "in full dark, the camera is essentially useless for plate readability — the dynamic range is insufficient".

Side-by-side comparison to GoPro Hero 13 Black: on the same ride, same angle, same lighting, the GoPro had significantly better image stabilization (HyperSmooth 6.0), significantly better license plate readability (in sun-behind conditions, the GoPro got 25 of 50 plates vs the RCT715’s 1 of 50), and significantly better low-light performance. The GoPro is 3x the price of the RCT715 ($399 vs $399 — actually the same price!), but the GoPro is a real sports camera and the RCT715 is "an event recorder".

Wi-Fi transfer speed: the reviewer tested the Wi-Fi transfer from the RCT715 to the phone. The result: "painfully slow". The reviewer could not get preview mode to work. The fastest way to access the recordings is to remove the Micro SD card and read it directly.

Long-term Use

Battery: tested across 4 modes. Solid + camera on 5h, Peloton + camera on 4h, Night Flash + camera on 4h, Day Flash + camera on 6h, Day Flash + camera off 10h. The reviewer notes: "for a buyer who does not need the camera, the RTL 515 at 16h in solid mode is the right answer".

Camera in real-world use: the camera is "an event recorder, not a sports camera". The 1080p quality is acceptable for incident documentation, but the lack of image stabilization makes the video shaky. The lack of lens protection means the camera is vulnerable to road grit. The reviewer strongly recommends a protective lens cover for off-road use.

Varia app in real-world use: the Varia app is "a usability disaster". The Wi-Fi transfer is slow, the preview mode does not work, the file structure is a mess (132 files for 5h of recording), and the app cannot be expected to work for in-ride access to the camera. The fastest way to access the recordings is to remove the Micro SD card and read it directly.

Incident detection in real-world use: the incident detection only works when paired with a compatible Garmin Edge / wearable. When a crash is detected, the RCT715 saves a video clip of the incident (with before + during + after footage). The reviewer notes: "this is a real-world win for safety — but it requires a Garmin Edge / wearable".

Competitor Comparison

Garmin Varia RearVue 820 ($299) + GoPro Hero 13 Black ($399). The two-device option. $698 total, ~$300 more than the RCT715, but the camera is meaningfully better (HyperSmooth 6.0, 4K, license-plate readable in sun-behind conditions). The two-device option is the right answer for a buyer who wants a better camera.

Garmin Varia RTL 515 ($199 on sale). The radar-only option. 140m detection, 16h battery, 71g, no camera. The RTL 515 is the right answer for a buyer who does not need the camera.

Magene L508 ($129) + GoPro Hero 13 Black ($399). The budget option. $528 total, similar radar quality, similar camera quality to the two-device option above. The Magene + GoPro option is the right answer for a budget-conscious buyer who wants a camera + radar at $130 less than the RCT715.

Final Verdict

The Garmin Varia RCT715 is the only product that combines a Varia-quality radar with a 1080p camera in a single 147g unit. The radar is best-in-class. The camera is subpar. The Varia app UX is poor. The 16GB SD card is too small. The 147g weight is 2x the RTL 515 but the battery is not 2x. The RCT715 is the right answer for a buyer who wants a single integrated system. The Varia RearVue 820 + a GoPro is the right answer for a buyer who wants a better camera.

Consider at $399 if: you want a single integrated system (radar + camera + light) and are willing to live with the camera limitations. You already have a Garmin Edge / wearable and want incident detection. You want a stronger mounting system than the RTL 515. Skip at $399 if: you want a sports camera (GoPro is the right answer). You want a license-plate-readable camera (no current bike camera does this reliably at speed). You want long battery (the RTL 515 is the right answer). You do not want to use a 147g unit on the seat post.
