If you have selected a reliable brand to buy a driving recorder, you need to focus on analyzing some product parameter before you purchasing a driving recorder, it seems like shooting angle, resolution of picture, compressed format, caching, and we also need to know whether the video can be closed manually; whether it can record a video normally at emergent situation; whether no jamming to other electric products and whether purchasing with card etc.

Shooting angle

The shooting angle is 100 degree for ordinary driving recorder, which is basically  enough to make sure shooting the two lane side of vehicle. Of course, bigger angle is better, and the expense is more too.

Resolution of picture

Generally video resolution  is 1280 * 720, which can promise take a clear picture for license plate in ahead, and license plate of side lane will be a little vague in the driving recorder. In addition, the photosensitive ability of SMOS chip in driving recorder and the quality of lens’ glass is connected with the shooting effect at night.

Compressed format

Most of driving recorder use compressed format H.264 .  Without a good compressed format but not losing frame, which require bigger storage capacity and higher reading speed of memory card. The size of 1 minute fragment of 720p resolution H.264 compression is about 60MB. In terms of drivers, it is helpful to choose a reasonable recording interval and volume for providing accident evidence in time, and 1 minutes as a interval time is appropriate.

Cache

A bigger volume of cache can bring smoother video and better memory card compatibility.

Emergency video

If there is a important video you want to leave, and the driving recorder also need to shoot video next,  which cause the important video will be deleted at the next time, for solving this situation, it occurs a emergency video design for keeping a special video,  so that if you just press a key manually, you will force the video to be saved without being automatically deleted when the card is full. Automatic emergency recoding video is the use of gravity sensor. It will automatically protect this video without being automatically covered and deleted during monitoring  a violent vibration on car, this function will be useful for vehicle collides.

Shielding measures

In order to decrease the cost o products, the copycat products always do not take any shielding measures and without strict test for their products, which will cause this products disturb some electronic products, such as GPS navigation  , remote control, audio, tire pressure meter, and driving computer, etc.

Whether purchasing with card

Driving recorder video with high definition picture,  always has a big volume up to hundreds MB per minute, so that there will be a strict request for reading speed of memory card, and  I advise driver purchase a superior card, because the slow speed card driving recorder is easy to be out of order.

AHD adalah singkatan dari Analog High Definition, jadi kamera AHD adalah kamera analog berdefinisi tinggi, sinyal transmisinya adalah sinyal analog berdefinisi tinggi. Berbicara tentang definisi tinggi, secara singkat, kita biasanya menyebut video berdefinisi tinggi dengan resolusi fisik lebih dari 720p, yang disebut sebagai HD.

Teknologi AHD dapat mencapai transmisi yang andal untuk sinyal video definisi tinggi (HD) pada jarak ultra jauh (500 meter) melalui jalur transmisi analog yang sudah ada. Teknologi ini menggunakan pemisahan sinyal Y/C yang canggih dan teknologi penyaringan simulasi, yang dapat secara efektif mengurangi noise warna di area frekuensi tinggi, sehingga kualitas gambar menjadi lebih baik. Dibandingkan dengan produk definisi tinggi tradisional, kualitas gambar kamera AHD mengalami lompatan kualitas dan peningkatan yang signifikan, dengan kejernihan tertinggi yang setara dengan level HD 1080 penuh jaringan.

Kamera AHD Fitur dan keunggulan:

• Lebih jelas: pemisahan warna cerah yang canggih, penyaringan sinyal, teknologi pengurangan noise 3D, kejernihan gambar yang lebih tinggi, dan kemampuan pengurangan gambar yang lebih baik; ;
• Jarak transmisi: Gunakan transmisi koaksial, kabel koaksial standar 75-5 dapat mentransmisikan sinyal hingga 500 meter;
• Tanpa penundaan: data yang direkam dikirimkan ke monitor tanpa enkripsi, secara real-time, dan dengan kualitas tinggi;
• Kompatibel: Kompatibel dengan D1/960H standar, kompatibel dengan periferal analog (termasuk distributor, matriks, dll.);
• Mudah dioperasikan: mendukung desain menu OSD, atur sesuai keinginan Anda;
• Murah: harga simulasi standar untuk produk berkualitas tinggi definisi tinggi;
• Integrasi tinggi: Harga chip front-end AHD untuk produk berkualitas tinggi definisi tinggi;
• Standar terbuka: standar terbuka untuk pihak ketiga, kompatibel dengan produk AHD dari produsen lain, mempercepat perkembangan pasar.

Kamera AHD mengikuti metode simulasi transmisi definisi standar, yang dapat mengurangi kompleksitas konstruksi dan implementasi, mengurangi biaya bahan tambahan, serta mempertahankan kompleksitas dan persyaratan teknis tenaga kerja konstruksi. Kamera ini sangat cocok untuk meng-upgrade sistem lama, Anda dapat dengan mudah meng-upgrade dari definisi standar ke definisi tinggi tanpa mengubah sistem asli. Selain itu, kualitas definisi tinggi dengan harga definisi standar membuat kamera AHD memiliki ruang pengembangan yang sangat besar baik di pasar sipil maupun industri (seperti kamera mobil AHD).

There are two types of reverse car camera: wired reverse camera and wireless reverse camera, wired reverse camera is simple and reliable, but need wiring inside the car or other vehicle; wireless  reverse camera does not need wiring along the interior of car or vehicle,  so it is easy to install, but you need additional wireless receiver . However, current wireless receiver receiving effect is still not very ideal, so most reversing cameras in the market are still wired reverse camera. You can choose wired reverse camera from the following aspects :

Camera Chip

Camera chip is the most important part in reversing camera , they can be divided into CCD and CMOS two kinds. CMOS is mainly used in low image quality products,  its advantages are manufacturing costs and power consumption is lower than the CCD, the disadvantage is the CMOS camera has high requirements for the light source;  CCD chip is mainly used in photography, camera , some high-end technical components also comes with a video capture card.  CCD and CMOS in the technical and performance gap is large, in general, CCD effect is better, but the price is more expensive.

Resolusi

Resolution is one of the important indicators when choosing reverse cameras. In general, high-definition reverse camera, its image quality will be better, reverse camera resolution above 420 line has become a mainstream in reversing camera products,  380 lines reverse camera, if debugging properly, can still be a good choice. However, according to different camera chip level, different components, including different technicians’ debugging level , the same chip or the same level reverse camera product output quality may be different; on the contrary, high-definition reverse camera products night vision effect will be reduced.

Night vision

Night vision effect related with reverse camera resolution, higher resolution car reversing camera night vision effect will not be very good, this is because the chip itself, but good quality reverse cameras should have night vision function, and will not affect the image output effect; although the color may be worse, but clearly should not a problem. Car reverse camera with built in infrared light night vision effect will be more clearly visible.

Tahan air

Reversing camera products are basically equipped with waterproof function.
Summary: choose the right reverse camera from the camera aspects per your requirements, the most important thing is to check and  compare the actual image affect.

Ini adalah 100% legal untuk menginstal kamera dasbor untuk mobil Anda, truk dan jenis kendaraan lainnya, dan legal untuk merekam video di sekitar kendaraan.

Namun, membagikan video yang diambil (yang memiliki wajah manusia, plat nomor mobil orang lain, dll) ke teman atau jejaring sosial seperti Youtube, facebook masih belum ada jawaban yang pasti mengenai legalitasnya, karena video tersebut dapat melanggar privasi orang lain. Jadi kami sangat menyarankan untuk menggunakan kamera dasbor sebagai penggunaan cadangan, sehingga dapat membantu Polisi dan perusahaan Asuransi untuk mengidentifikasi tanggung jawab dalam kecelakaan lalu lintas. Dan jika Anda ingin berbagi keindahan yang ditangkap selama perjalanan Anda dengan teman-teman Anda, lebih baik tambahkan beberapa topeng pada wajah manusia dan plat nomor mobil orang lain.
