An AJP file .ajp is only defined by what produced it, most commonly a CCTV/DVR export storing video in a proprietary format that regular players won’t recognize, 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 the file wasn’t generated by a camera system, an AJP may be produced by older software like Anfy Applet Generator or show up in CAD/CAM workflows such as Alphacam and therefore isn’t video, and you can usually tell which type you have by comparing file size and companion files—CCTV exports are large to enormous and may include viewer programs, while project-style AJP files are lightweight and appear with web or CAD assets, and checking Properties or opening it in a text editor briefly can show readable text for project files versus gibberish-like binary for DVR footage.

To open an .AJP file, the correct method depends entirely 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. If you enjoyed this article and you would certainly such as to receive additional information regarding AJP file technical details kindly go to the webpage. 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 matching viewer is provided, you should find the system model and download the official CMS/VMS or backup viewer, since many CCTV vendors restrict AJP playback to their own client; open the client first, use its Open/Playback/Local File menu to select the AJP, and if the file plays but cannot be exported, the last possible solution is screen-recording the playback, which takes more effort but may be the only option with older formats.

If the AJP didn’t originate from surveillance equipment, it might relate to outdated animation tools or CAD/CAM software, meaning it requires the original application to open it, so check the surrounding folder for hints such as project-related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 paste the AJP’s size along with names of nearby files or a screenshot, and I can almost always tell whether it’s CCTV-related and advise which playback tool will open it.
