An AJP file .ajp shifts purpose based on what generated it, most commonly appearing in CCTV/DVR workflows where footage is exported in a proprietary format that won’t run in VLC or WMP, produced when a user selects a channel and time frame and exports to USB or disc, often paired with a viewer tool like a Backup Player / AJP Player for playback and optional conversion.

If an AJP file didn’t originate from DVR footage, it may belong to 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 relatively small 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 proper step is tied to the system that made it because Windows and standard video players generally can’t parse it, and if yours came from a DVR export, the recommended solution is to look in the same export directory for the included playback tool—names like Player.exe, BackupPlayer.exe, or AJPPlayer.exe—launch it, load the AJP, and then use its export/convert feature to obtain a normal MP4 or AVI file.

For those who have any concerns regarding in which along with how you can use AJP file unknown format, you can e mail us on our web site. 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 takes time but can be necessary for older locked formats.

If the AJP didn’t originate from surveillance equipment, it might come from outdated animation tools or CAD/CAM software, meaning it requires the original application to open it, so check the surrounding folder for hints such as project-related filenames, readmes, or CAD formats like DXF/DWG, then install the correct program and open the file through it, noting that smaller sizes usually fit project files while very large sizes resemble CCTV containers.

If you prefer, you can tell me the size along with names of nearby files or a screenshot, and I can almost always identify the correct type and advise which playback tool will open it.
