While dashcams can provide accident evidence and driving safety assistance, they also have some drawbacks that need attention. First, continuous operation may cause battery drain, especially when the vehicle is parked for extended periods. It is advisable to choose products with voltage detection to prevent over-discharge. Second, improper installation may obstruct the driver's view or interfere with airbag deployment. Some low-end models produce blurry footage in low-light or backlit conditions, failing to capture license plates clearly. Consider devices equipped with Sony IMX series sensors and an aperture of F1.5 or wider. Moreover, distortion at the edges of wide-angle lenses could lead to misinterpretation of accident liability; a 140°-150° physical wide angle offers better practicality. Lithium battery models risk swelling in high temperatures, making supercapacitor-powered units preferable for tropical climates. Price-wise, basic models range from 300 to 500 ringgit, while 4K smart models may surpass 1,000 ringgit-choose based on actual needs. Regular memory card formatting and lens cleaning ensure optimal performance and prevent recording failures during crucial moments.
