Mobil 1080p Kamera Monitor Waterproof High Definition Sistem Kamera

Sistem Pemantauan Kamera Kendaraan Definisi tinggi tahan air belakang sudut lebar 1080P dalam pemantauan mobil

Ada dua jenis kamera belakang: kabel dan nirkabel.  The wired method is simple and reliable   but it requires wiring inside the vehicle body    The wireless method does not require wiring inside the vehicle body and is easy to install    but requires the addition of a wireless receiving module    Due to the unsatisfactory reception performance of wireless receiving modules nowadays   they are more or less susceptible to interference from the usage environment    Generally    reverse cameras still use wired methods
Pertanyaan berikut adalah: Bagaimana sistem navigasi portabel tahu bahwa pengguna mundur dan segera beralih ke fungsi rearview

Ada tiga cara:
Metode pertama adalah yang paling bodoh tapi juga yang paling sederhana dan paling dapat diandalkan yang menggunakan tombol pada navigasi portabel
Tombol tertentu dapat didefinisikan sebagai tombol switch reverse rearview Sebelum membalik pengguna menekan tombol ini dan sistem segera beralih ke mode reverse rearview Setelah membalik, press the button again and the system will switch back to its original interface   This method is simple and reliable    and there is no need to add anything to the extension part of the bracket   But it requires manual operation and is not intelligent enough

The second method is to detect the reverse signal (the simplest method is to take the control signal from the reverse light)   When the user engages the reverse gear    the reverse light lights up and provides a switch signal    which is used to control the switch of the reverse image system   This method is quite intelligent    with good accuracy and stability

The third method is to continuously check whether the CVBS signal is valid within the written navigation system to determine whether it is reversing   When reversing    turn on the reversing camera    and the camera will send a CVBS composite video signal to the interior of PND through the bracket interface    If PND detects a valid video signal    it is considered to be in reverse mode    This method can be considered the most intelligent and accurate method
