A borescope is used for a wide variety of inspections, while an endoscope – while similar in concept – is for medical inspections. Borescopes can be used to inspect machinery and engines, pipes and gun barrels, and hidden areas inside the home live cavity walls. Endoscopes, by contrast, are used to inspect body cavities and organs. What kinds of borescope are there? A lot of borescopes let you take a look where you can't get your eyes or your camera, but by incorporating an articulation tool this can be more easily positioned to give you exactly the view you need. The DS500 is a fine tool, capable of performing its duties even in a rough and tumble environment. The build is confidence-inspiring, always appreciated in the kind of environment where serious work is being done, and we really appreciated the case and addition of a magnet as well as a standard hook –you’ll never lose a screw again.Camera resolution: the more the better, though remember these cameras must be tiny to be useful. Be aware that some makers 'upsample' resolutions to make it sound better than it actually is (a common way is recording higher resolution video than the camera's sensor can make use of). This small, easy-to-use scope camera lets you record each of your shots with great image quality. The camera can be attached to any standard NATO/Picatinny rail that can be found on most guns. The Runcam 2 has a built-in battery, that will last you for 240 minutes with the highest resolution setup (1080P@60fps).

To set up the Triggercam you need to link your smartphone or tablet to the Triggercam’s wi-fi and then fine-tune the settings from there, especially the reticle focus. Once linked, you adjust the focus with the wheel, which streams the image direct to the app. It’s basically set and forget. It might not look like much, a kind of coated wire-frame arrangement, but it’s actually much easier to grip than, say, the plastic spools common on extension leads. That thoughtful quality extends to the highly durable display which is both waterproof and oil/chemical resistant too. You need to worry about delicate touch screens, as the controls are all on robust buttons around the display. It’s all very straightforward and well thought out, but best of all it offers a simple and reliable solution to an irritating problem that doesn’t get in the way when you’re shooting. It’s a brilliant training aid for new shooters, as well as offering a easy method of recording your own performance in a comp or adventures in the field. Memory card storage: most borescopes offer fixed internal storage but some have removable SD cards – useful if you need to offer images to a client. The 40mm version doesn’t work with the NOVRITSCH scope and mount. It is too long. A better way is to mount it on the barrel with this mount.

Wi-Fi: this could be handy for viewing footage on your smartphone at a safe distance from the actual dirty work The Depstech DS450 (and its dual-lens siblings built on the same case) feels as natural to use as a mobile phone. The 4.5-inch IPS screen is about the same size – with the camera cable connecting at the top centre – and is easier to hold vertically. The camera itself is well-lit and provides good visibility, though the LEDs produce a distinctly blue-tinged light. The claimed 1.96-200 inches focal range seems somewhat optimistic though, or perhaps a 2592 x 1944 pixel screen is simply too much resolution for the camera. Screen size and resolution: the bigger and better the screen, the easier it is to get a proper view of what you're looking at. The accessories are useful, and the handset is easy to hold. While there are more expensive, bigger, and very rugged devices available (the DS500, for example), this handset and probe arrangement seems ideal for all but the most aggressively dirty environments.

Just put it on your gun and start recording your gameplays! The custom lens is already installed and the settings are optimized for the highest quality. There are two different lenses to choose from, depending on your role on the Airsoft battlefield and the type of footage you are looking to capture: Over the years I’ve tried all manner of phone and camera clamps to capture video and still images from scopes to illustrate articles or enhance videos. Invariably the results have been iffy at best, or simply too cumbersome or unreliable to deploy in the field. The Scope Cam 24Ksupports up to a maximum of 128GB SDCards (Class 10/UHS-I /UHS-II /UHS-III). The minimum capacity for an SD card used in the Scope Cam 2 4K is 32GB.Please ensure that the file format of your SDCard is FAT32 or exFAT, otherwiseerrors may occur. SD Cards above 64GB must be formatted via the RunCam App. If your device is not registering the SD card it is likely the write speed of your SD card is too slow. It’s something of a niche product admittedly, but if you want a scope-cam solution you can take anywhere and perhaps even leave on your scope permanently, it’s ideal. The tech specs are impressive, with a wide variety of video modes as well as stills recording.
