An AJP file formatted as .ajp is only defined by what produced it, most commonly a CCTV/DVR export storing video in a proprietary format that is incompatible with VLC/WMP, created when someone exports footage from a chosen camera and timeframe to removable media, and usually accompanied by a special viewer like a Backup Player / AJP Player that can open and occasionally convert it.

If an AJP file didn’t originate from DVR footage, it may instead stem from old software like Anfy Applet Generator or CAD/CAM applications such as Alphacam, so it’s not video, and you can usually pinpoint the type by looking at file size and folder structure—CCTV AJPs are very large, often accompanied by viewer programs, whereas project-style AJPs are more compact and stored next to web or CAD resources, and by checking Properties or safely viewing it in a text editor, readable text hints at a project/config file while mostly unreadable symbols indicate a binary DVR container.

To open an .AJP file, the correct method varies based on the software or device that created it, since Windows and common media players usually fail to guess the proper format, and if the file came from a CCTV/DVR export, the most reliable option is to use the matching viewer/player that accompanies that DVR system, typically found in the same USB/CD/DVD/folder as the AJP and named something like Player.exe, BackupPlayer.exe, or AJPPlayer.exe, which you can run to load the file and then use its own export or convert feature to produce a standard MP4 or AVI.

If no viewer is bundled, the next step is to check the DVR/NVR brand and model—or at least the software used for live viewing—and download the official CMS/VMS/backup viewer from that vendor, since many CCTV systems rely on their own PC client to decode AJP files, and once installed you should open the client first, use its Open/Playback/Local File option to load the AJP, and if it plays but offers no export feature, the final fallback is to screen-record the footage full screen, which isn’t ideal but can be necessary for older locked formats.

If your AJP didn’t come from a camera system, it may be tied to an older project/animation tool or a CAD/CAM workflow, meaning it opens only in the software that created it, so the best approach is to inspect the source folder for clues—such as app names, readme files, project folders, or CAD-related extensions like DXF/DWG—then install that application and load the AJP from within it, using file size as a hint since large files usually indicate CCTV footage while smaller ones suggest project/config data.

If you want quicker identification, just paste the size and a few folder filenames (or a screenshot), and I can usually detect if it’s CCTV footage and guide you to the right viewer/player.
