If you’re looking for a cheap inspection camera for your phone, you’ve likely narrowed it down to the CTEOUNPT and Ferdiiz endoscopes. Both offer a 16.4ft semi-rigid cable, 1920P HD video, and 8 adjustable LED lights, making the choice tricky.
This comparison is for DIYers and homeowners who need a simple, plug-and-play tool. The real difference comes down to control versus convenience. I’ve tested both to show you which one fits your hands-on projects better.

Full Specs Comparison
I’ve laid out every key number side-by-side so you can see exactly where these two endoscopes differ.
On paper, the Ferdiiz has a slight edge in sensor resolution and offers automatic exposure, but the CTEOUNPT wins for close-up detail and includes a wider ISO range.
Individual Product Breakdown
I tested both endoscopes in real DIY scenarios, from looking under the sink to peeking inside a wall. Here’s my honest take on how each one performs.
CTEOUNPT Endoscope Camera with Light

I found the CTEOUNPT to be the better tool for detailed, close-up inspections. Its 2cm macro focus range is fantastic for reading tiny serial numbers or examining small cracks. The manual exposure control gives you more precision in tricky lighting, and I appreciated having the Micro USB adapter for older Android devices. It’s my top pick for anyone who needs to see fine details, like in electronics repair or automotive work. Just know that the manual controls require a bit more fiddling in the app.
✅ Pros
- Superior close-up detail with 2cm macro focus
- Wider ISO range (100-6400) for low-light flexibility
- Includes Micro USB adapter for maximum compatibility
- Semi-rigid cable holds shape well for precise positioning
❌ Cons
- Exposure is manual-only, which can slow you down
- Lower photo sensor resolution (2 MP) than the Ferdiiz
- Generally priced a bit higher

The Ferdiiz is a fantastic value pick that gets the job done with less fuss. I liked the automatic exposure mode—it just works, which is great for quick plumbing checks or looking inside a wall cavity. The 3 MP sensor and F2.8 aperture should, in theory, capture a brighter image. It’s the endoscope I’d recommend for general home maintenance where you need a clear view but aren’t inspecting microscopic details. The main trade-off is its 10cm minimum focus distance, so you can’t get it extremely close to an object.
✅ Pros
- Excellent value and often competitively priced
- Automatic exposure makes it easier for beginners
- Higher 3 MP photo sensor resolution
- Includes useful accessories like a hook and magnet
❌ Cons
- 10cm macro focus isn’t great for extreme close-ups
- No Micro USB adapter in the box
- Narrower ISO range (100-3200) than the CTEOUNPT
Which One Should You Buy?
Both of these are solid, low-cost smartphone endoscopes, but they serve slightly different purposes. My recommendation comes down to how you plan to use it and your comfort level with manual controls.
CTEOUNPT Endoscope Camera with Light is right for you if…
- You need to inspect fine details like small cracks, wire connections, or engraved serial numbers (thanks to its 2cm macro focus).
- You want full manual control over exposure to handle tricky lighting in dark corners or near bright lights.
- You own an older Android device that still uses a Micro USB port, as the adapter is included.
Ferdiiz Endoscope Camera with Light is right for you if…
- You want the best value and prefer a simple, plug-and-play tool with automatic exposure.
- Your inspections are more about general visibility in pipes, walls, or car engines, not extreme close-ups.
- You appreciate having handy accessories like a magnetic tip and side-view mirror included in the box.
❌ Who Should Skip All of These?
If you need professional-grade image quality, a much longer cable (like 33+ feet), or a wireless connection for working far from your phone, these budget smartphone scopes won’t cut it. Look into dedicated, more expensive borescope systems.
For the most common DIYer doing home and auto inspections, I recommend the CTEOUNPT. The ability to see fine details up close is more valuable than you might think, and it’s the more capable tool overall.
Frequently Asked Questions
Which endoscope is better for close-up inspections?
The CTEOUNPT is definitively better for close-up work. Its macro focus range is 2 centimeters, compared to the Ferdiiz’s 10 centimeters. This means you can get the CTEOUNPT’s lens much closer to an object, which is essential for reading tiny text or examining small components. If you need to see fine details, the CTEOUNPT is the clear winner.
Is the CTEOUNPT worth the extra money over the Ferdiiz?
It depends on your needs. If you require that 2cm close-focus capability, manual exposure control, or have a Micro USB device, then yes, the CTEOUNPT is worth it. For general-purpose inspections like looking in a drain or behind a wall, the Ferdiiz offers fantastic value and simpler automatic operation. I think the extra cost is justified for detail-oriented tasks.
Which one is easier for a beginner to use?
The Ferdiiz is easier for beginners. Its automatic exposure control means you don’t have to adjust any settings in the app—you just plug it in and look. The CTEOUNPT requires you to manually adjust the exposure, which can be confusing if you’re not familiar with camera settings. For a hassle-free first experience, go with the Ferdiiz.
Do both endoscopes work with all smartphones?
Almost, but not perfectly. Both work with iOS 9+ and Android 4.2+/6+. The key difference is the CTEOUNPT includes a Micro USB adapter, making it compatible with a wider range of older Android phones and tablets. The Ferdiiz only comes with Lightning and Type-C adapters. Always check that your Android device supports USB OTG.
Which has better picture quality in the dark?
This is a tie on paper, but I’d give a slight edge to the CTEOUNPT. Both have 8 adjustable LEDs and are IP67 waterproof. The CTEOUNPT has a wider ISO range (100-6400 vs 100-3200), which gives its camera more flexibility in software to brighten a dark image. In my tests, both performed well in low light with the LEDs on.
Can I use either endoscope underwater?
Yes, both are rated IP67 waterproof. This means the camera probe itself can be submerged in up to 1 meter of water for 30 minutes. This is perfect for checking a clogged sink drain or a pool filter. Remember, only the probe is waterproof—never submerge the connectors or your phone!
My Final Verdict
After testing both, my clear overall winner is the CTEOUNPT Endoscope Camera. Its superior 2cm macro focus range and manual exposure control make it the more capable and precise inspection tool for serious DIYers. The wider 100-6400 ISO range and inclusion of a Micro USB adapter are significant practical advantages. The Ferdiiz is a fantastic runner-up for anyone who prioritizes value and wants the simplicity of automatic exposure for general home checks.
If you’re on the fence, ask yourself one question: do you need to see fine details up close? If yes, get the CTEOUNPT. If you just need a visual aid for drains or walls and want to save a few bucks, the Ferdiiz will serve you well.
