Wireless Endoscope，Letike WiFi Borescope Waterproof Inspection Camera 2.0 Megapixels HD Snake Camera for Android and iOS Smartphone, iPhone, Samsung, Tablet Black(15FT)

This endoscope works as advertised. I used it to aid in tracking down the source(s) of an oil leak in my car's engine. It can be used wireless with the wifi device or you can plug it directly into a computer if you wish. You can also use a USB A to micro USB or USB type c dongle to connect it to a phone or tablet as well. The video quality is good and there didn't seem to be much lag when viewing on the HD See app. One of the most useful features is the semi rigid cord. You can bend it any which way you want and it will keep its shape. The mirror, waterproof, hook, and magnet attachments screw on the the end of the camera so they won't fall off in tight spaces. Great for finding and grabbing a bolt or nut whenever I drop them in the engine bay. The light on the end is dimmable so you can have it on the brightest or completely off. I needed to turn the light completely off because I was using a black light and UV dye to pinpoint the oil leak in my engine.To connect the camera over wifi on a phone or tablet, you need to MAKE SURE you are connected and stay connected to the endoscope's wifi network (YPC_***) There is a solid blue and solid green light when the wifi transmitter is powered on. The green light is wifi and it will flash green when it's connected.ANDROID PHONE USERS:If you are having trouble connecting to the camera, you may need to turn off your mobile data. If you have a cellular data plan on the phone you wish to connect the camera to, the data may interfere with the connection as it did on my android phone. I tried it on an old phone of mine and had no problems. Make sure you're connected to the endoscopes wifi, go to your settings drop down menu and tap on mobile data to temporarily turn it off and the camera will connect right up.
