POSM's Got Em: XBOB-4 Video Overlay

POSM’s Got ‘Em are short articles that take a closer look at our array of products and features. Maybe you’ll find new solutions to old problems you didn’t know we addressed. In this article, we take a closer look at XBOB-4 Video Overlay Generators.


The XBOB-4 (fourth generation manufactured by Decade Engineering) performs a single, vitally important function for pipe inspectors. It lets you overlay text on your video screen, and does so with a great deal of versatility.

You can type observations on the screen “live” during the inspection. Using POSM Software with the XBOB-4 gives you “text to speech" capability: you type it, the computer displays the text, and a voice speaks it! (Voice synthesis works through SAPI)

The XBOB-4 offers an additional feature beyond text functionality. The box is connected to your cable reel, so as the cable un-spools, the XBOB sends a pulse to your screen. The benefit of this is that the XBOB-4 tracks the distance as your crawler travels forward or backward along the pipe. When using POSM Software and an XBOB-4, our software has a process to re-calibrate the measurement whenever necessary, so distances are highly accuracy.

Here's a tutorial video from POSM Software showing how to test the pulse function of the our XBOB box.

When using POSM with the XBOB-4, text is pre-set for video inspections to display white text against a black background. We did this so that the words are always easy to read, whether your video is very dark, very bright, or shifts radically during the inspection.

WORTH NOTING: After the inspection, POSM has its own handy video overlay feature that lets you or a team member add text to the observation photos.

The Decade Engineering video overlay model is the only XBOB-4 we sell. It supports multiple languages. Decade Engineering encases the electronics in a surprisingly durable plastic box that is more than tough enough for our industry. The box hooks into your system simply, with just a DC adapter, RS-232 serial cable, and video In/Out. We’ll add any cables and cords if you need them. You can order the Decade Engineering XBOB-4 directly from our shop for $750.00 by clicking here.

Every computer inspection system in our industry has a video overlay box, and it’s a good idea to keep a few extra boxes in storage. So if you need to restock, or most especially if you’re not happy with your video overlay, POSM’s GOT ‘EM! Boxes are delivered do-it-yourself or you can contact our technical support to get you started.
