Bel STi vs X50 vs RX65 vs V1
For this test, four runs were conducted with each of the four radar detectors, two runs coming towards the speed camera (facing the vehicle) and two runs with the Multanova facing the rear as traffic moves away from the camera. Only one radar detector was switched on at any given time to eliminate possible interference.
First run the Bel STi alerted at approximately 18 seconds before passing the camera at 60km/h. Note the camera is well out in the open, with the radar beam firing towards the front of the car as it approaches the speed trap, thus provided adequate warning time. In this type of set-up, the photo is taken at a point 70m in front of the camera, when set up at an angle of 22 degrees to the road. Most camera set-ups do not offer this luxury and are usually a lot harder to detect.
Second run, a U-turn was made and the test vehicle driven back towards the multanova camera. This time, the camera's radar beam is firing away from the car, detecting the vehicle as it passes the camera and is moving away. In this situation you are relying on the radar beam reflecting back towards the detector - making it even more difficult to detect. The photo is taken approx 50-70m past the camera on multi-lane set-ups, but can be as short as 10m on single lane roads. In this test, the Bel STi alerted about 5 second before drawing level with the speed camera. In this video you can see (on the right of the picture) a tree bearing purple flowers. In front of this tree is a metal guard rail, and if you pause the video, you can see the speed camera is set up exactly where this guard rail ends. On the opposite side of the road (the left of the picture) you can also see a silver guard rail. This guard rail finishes level with the one on the opposite side where the camera is set up. This gives you a point in each subsequent video, where the detector is level with the speed camera.
First run for the Escort (third run in total) the X50 faced the Multanova Speed trap. Here the Escort alerted approximately 18 seconds before passing the camera at 60km/h
Again, the test vehicle made a U-turn and headed back towards the camera facing the other direction. The X50 alerted approximately 4 seconds prior to drawing level with the camera.
First run for the Bel RX65 (fifth run in total) the RX65 faced the Multanova Speed camera (forward). Here the Bel alerted about 20 seconds before passing the camera at 60km/h - quite a surprising result considering it is sweeping the entire Ka (wide-band) frequencies.
Once again, the test vehicle made a U-turn and headed back towards the camera. The RX65 alerted about level with the speed camera - you can see the guard rail on the left of the picture disappear before the RX65 alerts. This is consistent with other tests using the Bel RX65, in that it does poorly against 34.3Ghz Ka-band cameras.
First run for the V1 (set in Euro mode) and being the seventh run in total the V1 alerted an impressive 28 seconds prior to passing the camera. The Ka-narrow programming allows the V1 to scan just the 34.3Ghz
As per previous runs in the opposite direction, the test vehicle made a U-turn and headed back towards the camera. This time, the V1 alerted 15 seconds before drawing level with the camera; a full 10 seconds earlier than the next best detector.
The second run for the Bel STi from the front gave 25 seconds warning at 60km/h, 7 seconds more than the first run.
In this run, the STi gave even less warning to the rear facing Multanova than it's first, approximately 2 second before drawing level. Unfortunately the video footage didn't work for the next three tests.
In this second run from the front for the Escort, the X50 alerted in very similar times to it's first attempt, approximately 19 seconds at 60km/h
Second set for the Bel RX65 (thirteenth run in total) the RX65 challenged the Multanova Speed camera from the front. This time the Bel initially alerted 23 seconds prior, then paused, then alerted again at 13 seconds prior, before finally giving a constant alert from 10 seconds until the cameras was passed. Notice in the video how the RX65 immediately finishes alerting when level with the speed camera.
Final test for the RX65 gave about 1 second warning before passing the camera.
Second run for the V1 in Euro mode gave 27 seconds warning, a shy second less than the first time.
Final test run (number 16) and the V1 gave an initial alert 21 seconds prior to passing the camera for just over 4 seconds in duration, then was quiet for 3 seconds, then began alerting continuously from 14 seconds prior to passing level with the camera at 60km/h with the camera facing the rear. Perhaps there was a better reflection from traffic coming in the opposite direction than in the first run, but none-the-less a clear winner against the Multanova 6F6F Conclusions For this test, it was interesting to see the results when the detectors challenged the camera facing the rear. As aforementioned, in this scenario, the detector is relying on the radar beam to reflect back from traffic coming in the opposite direction, as well as metallic signs, walls or other objects.
* In this run, the RX65 alerted at 23 seconds initially, then stopped. It alerted continually from 10 seconds prior. ** In this run, the V1 alerted initially at 21 seconds out (paused for three seconds), then alerted continuously from 14 seconds. The winner clearly was the V1, followed by the STi second, and the X50 in third. The RX65 came fourth as it had the lowest sensitivity coming at the Multanova from the rear, drawing almost level both times before alerting
