An AJP file .ajp doesn’t point to one single type depending on what created it, so its origin is the key clue, with the most common case being CCTV/DVR backups where the system saves recorded footage in a proprietary container that typical video players don’t support, produced when a user selects a camera and time range to export, usually writing the file to a USB stick or disc along with a viewer like a Backup Player or AJP Player that can play the footage and sometimes convert it to a standard format.
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 noticeably smaller 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 procedure is dictated by what created it because common players and Windows typically fail to open it, and for CCTV/DVR exports the most dependable approach is to run the bundled viewer/player—often found alongside the AJP under names like Player.exe or BackupPlayer.exe—use it to load the footage, and then choose its Export/Save/Convert option to create a standard format such as MP4 or AVI.

AJP file program look at our own webpage. If no viewer is bundled, the next step is to figure out 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 reduces quality but can be necessary for older locked formats.
If the AJP file doesn’t trace back to a DVR, it may represent older animation/app-creation tools or CAD/CAM workflows, requiring the same program that made it, so look around its folder for identifying app names, documentation, or related file types like DXF/DWG, then open it inside the correct software, noting that file size can guide you—tiny files usually mean project/config content, while huge ones are often CCTV backups.
If you want, you can share the file size and a few filenames from the same folder as the AJP—or even provide a quick screenshot—and with that information I can usually identify the CCTV/DVR type and suggest the most likely viewer/player that will open it.
