Extech Instruments HDV640W Inspection Camera Review

When it comes to a professional inspection camera system, the HDV640W 6mm Diameter/1 Meter Semi-Rigid Cable High Def Wireless Articulating VideoScope by Extech Instruments is a serious contender.

Different from the lower end inspection cameras systems, the HDV640W was created with high definition images in mind. The 5.7 inch LCD screen is large and offers a glare-free view. While that variety of imaging is expected at this level of technology, very few other inspection camera systems (at the same price) can compete with that type of imaging. Of course, images are not the only speciality of this system.

Key Features

Recording Capacity

The Extech Instruments HDV640 uses an SD memory card that stores both videos as well as images. In fact, it can store more than 14,000 still images or up to four hours of video – and not just any video, we’re talking high-quality video. And that video can also have voice annotation included in the video file so you’ll be sure to not forget those important details. Actually, while other systems do offer users the ability to share images and findings with clients and customers, very few are able to present the quality images that are presented with the Extech HDV640.

Small and Compact

This inspection camera system is small and it’s 6mm size fits well into most small spaces. Speaking of small, it’s signal is captured by the small high-def camera at the end of its probe. This signal is broadcast for up to 100 feet and displayed brightly on the lithium polymer battery (which surpasses the common lithium-ion batteries that are found on most inspection camera tools of this type).

Camera Control

The Extech HDV640W VideoScope features camera control that allows users to steer the camera around turns and provides viewing angles. This allows for less ambiguous views and images which can’t be controlled by lower end inspection camera systems.

Semi-Rigid Probe

The semi-rigid probe is articulated and is approximately 3 feet (1 meter) long. It’s completely sealed against dust and since it’s IP67 compliant, it’s also waterproof up (or down) to 3 feet. LED lights illuminate the field of view and the field can be adjusted to a viewing angle of 320 degrees. The superior quality of the probe, combined with the well-built quality of the inspection system gives users a step-up when it comes to the competition.

Our Verdict

There are a few important aspects of a good, quality professional inspection camera and one of them is versatility. The Extech HDV640 definitely delivers versatility. It’s scope length, precision, high capacity memory card, superior imaging/recording and ability to download images to a computer through a USB cord or directly from the SD card are huge, unsurpassed features of the Extech Instruments High Def Wireless Articulating Video Scope 6mm Diameter/1 Meter (3 feet) Semi-Rigid Cable.
