Two Sdetectors: front and rear #
Smart Radar supports two Sdetectors connected at the same time: one front and one rear. Choose Direction after entering the serial number, or in the device settings below GPS informer. Front is the default, so previously paired devices do not need pairing again.
Several devices can be saved for each direction, but only one front and one rear detector can connect simultaneously. Automatic reconnection preserves the assigned direction. The rear detector also works alone. In settings, the front card appears above the rear card; direction labels distinguish the devices when both directions are used.
Each detector has its own sounds, volume, muting and sensitivity. App quiet mode is shared. The first connection is announced; connecting the second while the first is connected does not repeat the announcement. Only a front detector disconnection is announced.
Sound priority and matching signatures #
Voice messages do not overlap. The front detector's beep takes priority: if the rear detects first and then the front detects, the beep switches to the front. When the front signal ends, the rear beep takes over. Brief dropouts do not cause an immediate switch.
For matching signatures on both devices whose episodes start less than 5 seconds apart, the name is not repeated twice. If the front name was already spoken, only the rear-facing phrase is added for the rear. If the rear name was spoken first, the front does not repeat it within this window. Timing starts at the beginning of an episode, not each Bluetooth packet. A different signature or a new episode outside the window is announced separately.
The rear signal includes the rear-facing phrase. This identifies the assigned detector direction, not proof of the measurement direction: a rear detector can receive reflections from a radar ahead. When muting is active, a second source of the same signature does not raise the beep volume again.
Stationary-camera filter for Sdetector #
In each Sdetector's settings, below Highway sensitivity, enable Disable RD when a fixed camera is within. The filter is off by default. Use the arrows to select 500, 1000, 1500 or 2000 m; the default is 1000 m. Front and rear detectors have independent settings.
The filter hides signature and K-band alerts, including sound and active signal indicators on the radar screen and in background displays. It does not switch off the detector hardware or disable camera-database alerts.
Any eligible stationary database point within the radius activates the filter, regardless of its direction or profile settings. Police posts, stopping-control cameras and dummy cameras do not activate it. If another eligible camera is also nearby, suppression still applies.
When you leave the radius, a signal that is still current starts a new alert episode. If GPS position is unavailable, stale or unreliable, or movement is estimated by sensors, the filter does not suppress signals.
The filter uses proximity to database points, not identification of the actual radio source. It can also hide a mobile-radar signal near a stationary camera. Enable it only if this trade-off suits you.
Status, direction and RD1/RD2 versions #
The front signal shows the signature name; the rear adds a rear-facing suffix, and a matching signature from both adds a both-directions suffix. The direction suffix is smaller than the name. Different signatures are displayed separately. Strength signs in PiP and the informative overlay overlap horizontally, with the front sign on top.
On the main screen, status dots above the speed number represent RD, K and MUT in that order: green means radar operation is enabled at the current speed threshold, white means K-band is enabled, and orange means muting is configured. Inactive states are gray. These are settings statuses, not detection indicators. With both detectors connected, the front group comes first, followed by a gray divider and the rear group.
In Android floating windows x1 and x2, front status dots appear above the speed and rear dots below it. These dots are absent from the Android informative overlay and iOS PiP. With both detectors connected, the header shows RD1 for front firmware, RD2 for rear firmware and BD for the camera database. A single detector uses RD. A version not yet received is shown as a hyphen in the dual-detector header.
Signal-strength color indicators #
After Sdetector connects, its signal bar appears on the radar screen. The front bar is at the top and the rear bar at the bottom. Levels 1–3 flash green 2 times per second, 4–6 orange 3 times, and 7–9 red 4 times. Colored and gray phases have equal duration.
Without detection, the main-screen bar stays neutral according to the day/night theme. In Android background display, inactive bars are hidden. iOS PiP uses small round indicators at the top and bottom and keeps their neutral gray state. Indicators respect the signatures and bands enabled in the profile.
