High-definition dash cams. The term “high resolution” can be confused with true HD video. HD video is 1280 x 720 or 1920 x 1080, referring to the number of pixels used to create the image being recorded.

In the last decade, the in-car video industry has undergone significant growth and change with the transition from analog to digital video systems. The new digital technology introduced many advances and features, such as improved video quality and pre-event video that forced manufacturers to develop new products and meet increasing expectations.
In-car video has become a highlight of the law enforcement market, and garnered national and international attention in the process. Few products demand such scrutiny and investment on behalf of an agency. Few programs within the daily operations of most agencies demand such significant attention and generate such enormous benefits. Sgt. Charlie Walker of the Winfield (Texas) police department says, “I don’t work without my camera. It’s the second most important piece of equipment I take to work, after my sidearm.”
Once again, a new wave of technology is sweeping through the industry. Since video has permeated the consumer market with advanced features like high definition (HD), live streaming and the ability to transfer files over a wireless network, the law enforcement industry has begun to have these same expectations of their in-car video systems. The obvious question is, “If I can record HD video and upload or stream it wirelessly from my cell phone, shouldn’t my in-car video system be able to do the same?”
Once this decision is entertained, it also brings into question how to efficiently manage HD files with their increased size over standard definition.
