Endoscopes were invented so physicians could look deeply into the human body’s hidden cavities. The ability to see inside places previously inaccessible was soon applied to many non-medical applications, such as precision mechanics, electronics and ergonomics.
A modern endoscope is a camera on a flexible stalk, with a light source, image sensor and optical-quality lens. People use endoscopes for automotive maintenance, industrial inspection, equipment repair and examining chimneys, ducts and drains. If you are looking for an endoscope with front and side cameras, take a look at the Teslong Waterproof Dual Lens Inspection Camera.
In factories, endoscopes may be wired into the electrical system, but wireless endoscope cameras have taken over as the choice of people who need to take an inspection camera along with them. Some have a built-in viewing screen, while others are made to be used with your smartphone as a separate viewer and recorder.
If you connect your endoscope camera to your smartphone, you’ll need apps to view your images and videos in real time. Apps are constantly upgraded, and may not work with smartphones running older software versions, so check before you buy.
All wireless endoscope cameras use rechargeable batteries. Budget endoscope cameras have batteries that may only last an hour or two, while higher-end models may keep powering your endoscope camera for four hours or more.
When the places you look into with an endoscope camera are dark, your device is the only light source you have. Look for multiple LED lights and ring lights, too. The more lighting you have, the brighter your pictures and videos, but the more quickly you’ll drain your batteries. The ability to adjust the lighting intensity is another good feature to look for.
Look for endoscope cameras that have slots for MicroSD cards so you can easily swap and share stills and videos. Always carry an extra card in case of unforeseen events.
It's handy to have a few attachments for when you snake your cable deep inside where your hands won’t reach.
Prices are determined by the quality of the camera, LED and battery, and length of the snake. You can expect to pay anywhere from $20-$200.
A. Start by gently wiping with a dust-free cloth, then use alcohol wipes to get dirty lenses really clean.
A. Wiggle the snake back and forth with small, gentle motions as you slowly exert mild forward pressure. Never try to force it when it encounters an obstacle — you will only damage it.
