You might have read stories about dash cams failing in cold weather. While the damage caused by a deep winter freeze is not as severe as the scorching summer heat, if a dash cam is outside of its operating temperature range, it will slow down or shut down. Don’t forget, the dash cam is just another piece of recording device, like your mobile phone or DSLR camera, and temperature outside of the dash cam's operating temperature range will affect the image sensors, which will affect the quality of the captured footage.
So what if temperatures fall below the operating temperature range and your dash cam won’t start? No need to panic just yet. Chances are, when temperatures drop to below freezing, the windshield will frost over, which means you will need to defrost the windows before you can drive off anyways. Luckily, the warm air you're blowing on the windshield is sufficient to warm up the dash cam, and when it's time to start driving, the dash cam would be ready to jump into action.
And what if there's snow and ice build-up or condensation on the windshield blocking the camera? Unfortunately, when weather and road conditions gets worse, excess of snow and ice accumulating on the windshield will block the dash cam's view, so would condensation. A proper installation can help lessen the problem. Like all electronics, dash cams tend to heat up when in use so if the dash cam is hugging the windshield, the heat it gives off is often enough to melt the snow and ice enough for you to wipe down.
What we recommend: While the IROAD X9 is an excellent camera for extreme heat conditions, we recommend the Thinkware U1000 2-CH 4K UHD dash cam and the BlackVue DR900S 2-CH 4K dash cam for winter driving.
