The quality of the Crenova endoscope is pretty good. In attached video I show a text in a magazine as I move the camera from touching the page to being about 10 inches away from the page. It has a sweet spot for sharpness of the image in the middle of that range, but you can read the text at all distances. The wire of the endoscope can be bent and it holds its shape as you move the wire around, this allows you to aim it at an angle not just pointing down.
The endoscope comes with app (available from GooglePlay). The name of the app is PLX_WifiCamera. The app also has iPhone version which I have not tried. Once I plugged in the camera into the WIFI unit I immediately saw the camera hotspot under WI FI connections on my phone and was able to connect to it with the password specified in the manual. The name of the hotspot is PLX_Camera. If you turn off the phone or the endoscope, you need to reconnect to the hotspot (not automatic re-connection).
The endoscope has a light on the end, which is very handy when you are looking at the dark hidden away places. The light switch is built into the cable attached to the camera. The switch is at the end nearest to the WIFI unit, so you can release the entire long cable and still be able to control the amount of light at the other end.
The app allows me to view the action on the phone. When I select I can take photos or record video.
The camera comes with a couple of accessories: a hook, a magnet and a mirror. The accessories lock onto the camera. The mechanism is a bit finnicky and does not look very robust but it does work. You can see me locking and unlocking the accessories in the video.
The documentation is fairly is not very detailed but it was enough for me to figure out how to connect the camera and turn it on.
Bottom line? This is a handy tool for hard to see areas, reasonable video quality, good price, it is a little tricky to control the aim. I hope the video helps you get a good idea of what to expect.
