First, it needs to be noted that several sellers on Amazon are selling essentially the same product, with a) rebranded firmware (custom startup logo and what else?) and slightly different camera focal-lengths/depths-of-field, There is no reason to suspect that any one "brand" is more or less durable/reliable than any of the others. So, free free to shop among the mainbodies by price. (The cables/cameras are interchangeable.)
The capture/viewing mainbody is NOT IP67 rated. Only the camera and attached USB-C cable are IP67 rated. This isn''t necessaririly a complaint, at this price-point. But it''s worth being aware of, in order to avoid problems down the road with water and dust, Boroscopes tend to be used under conditions of greater exposure to harsher environmental conditions than most other electronics.
The key to effectively using the camera/cable of this length is to begin with it wound in a reasonably compact "fireman''s coil," where each coiled loop is reversed against the previous loop, This alternate coil looping prevents forming kinks in the cable when unspooling the loops in order to gain further distance/extension from the mainbody.
The stiffness of the camera cable is an asset when pushing the camera through tight confines, like inside pipes. There is nothing more frustrating than trying to "push a rope."
The stiffness of the cable can be a problem when used in unconstrained space, because the camera tip will tend to whip around somewhat wildly, unless it is guided by an attached pole/pointer.
When pushing the camera/cable through water filled pipes/spaces, care must be taken not to abrade the cable sheath against sharp/rough surfaces, Iron pipes rust iinside and protruding surface rust flakes can abrade/compromise the cable sheath, resulting in water ingress inside the cable, eventually making it''s way to the camera. This is one way that the IP67 camera lens can suddenly fog-up.
Obviously, care should also be taken not to use the camera tip as an auger, as too much pressure/impact can physically compromise the lens itself, resulting in fluid ingress and/or actual lens breakage.
The camera cable attaches to the mainbody via a locking USB-C connector that can be released for disconnect via an adjacent push-button. This USB-C port seems to be reasonably durable.
As long as you know what the focal length and depth of field of the camera tip, the 1080HD video captured is quite useful and much more detailed than the 480SD (or less) video captured by lesser boroscopes/endoscopes.I have yet to offload any video to an external player, so I can''t say whether or not the 1080 is 1080p or 1080i, nor can I offer comment on frame rates.Snapshots are also very good with capturing detail.
The side camera (and side led illumination is also very useful.
Room for Improvement
1) There really needs to be an auto-focusing main camera lens that supports macro and panoramic views, That is just a matter of accessorizing the capture/viewer device.
2) It would also be very nice if the camera lens was made of anything more durable than simple glass. Hardened crystal? Gorilla Glass(TM)?
3) It would be very useful to be able to select the use of the tip camera with only the side LED light, when the front LED lights produce too much glare. Similarly, it would be very useful to be able to select the use of the side camera wth only the front LED lights,when the side LED light produces too much glare. Indirect lighting has long been a mainstay of photography/videography. .
4) There really needs to be an unobtrusive on-screen indicator clearly identifying which camera is in use, tip vs side.
Can this be achieved via firmware update?
5) It would be very nice if the built-in viewing software supported digital zooming, so that you aren''t forced to offload the captured video to another device in order to better inspect what has just been captured. Can this be achieved via firmware update?
6) It would also be nice if more metadata about the quality of video and photos were reported by the mainbody viewer/capture device. Can this be achieved via firmware update?
7) It would be very nice if the firmware could be end-user updated via firmware releases from Teslong.
All of these requests/suggestions come from real-world use of this very versatile device. I only wish it could be even more versatile.
I am satisfied with this device and my purchase of it.
I am always finding new and ongoing uses for it, to see very important things that would otherwise be next to impossible and/or physically dangerous for me to otherwise see.
It has played a huge role in recon/assessment of damage and subsequent repairs. This saves time, money and anguish.
Being able to inspect BEFORE THERE IS AN APPARENT PROBLEM is more than worth the price of purchase. Avoiding sudden, nasty surprises, hiding out-of-normal-sight, completely and favorably changes the balance between in-time maintenance and too-late repairs.
