4 Things to Consider When Buying an HD Recording System

With so many different cameras launching every day on the market, it may seem difficult for customers to choose the right one. The best way to pick one is to assess your requirements and decide on a recording system that meets your needs. Here are four factors you should consider when buying an HD recording system.


Camera Size


The advances in camera technology have allowed engineers to fit high-end features in cameras of all sizes. Small cameras work well if you want to install them in tight spaces such as a wing strut or tail boom of an aircraft. For instance, the TF-HDCAM measures 56mm x 19mm, making it the smallest barrel-style camera that resembles the size of a lipstick. The mini bullet camera can output HD-SDI to a DVR and supports live view on a monitor.


Shutter Type


The two main shutter types are rolling shutter and global shutter. With a rolling shutter, the sensor scans the image from one side to the other, while with a global shutter, the sensor captures the entire frame at once. Global shutter works best for professional filmmakers as it doesn’t produce a tilted or wobbly effect of the subjects in the frame. The TF-A1 boasts a CMOS global shutter and dual 3G-SDI outputs at 1920 x 1080 with LUTs and RAW support, making it a professional aviation camera.


Lens Options


Multiple lens options offer the opportunity to capture the landscape shots in many different settings. The more lens options you have, the more accurate you can get with your recording. The TF-3GSDI-CAM offers multiple CS lens options of 2.9 mm, 3.6mm, 4.3mm, 6.0mm, 8.0mm, and 12.0mm that shows 120° FOV, 92° FOV, 78° FOV, 54° FOV, 39° FOV, and 25° FOV respectively.

Real-World Application


Not all cameras are manufactured for the same purpose. Engineers need to design and develop the right housing and materials for its intended application. For instance, the TF-A1-M-WP is a miniature HD-SDI camera that has an IP67 rated waterproof housing, making it an ideal choice for marine applications. With multiple mounting solutions, you can install it on seaplanes and boats.
