In the testing I've done with these mics, they deliver very crisp and clear audio with some noise cancellation. I recorded some conversation while traveling recently, and the people wearing the mics were picked up extremely well despite road noise (which was not picked up), and anyone not wearing the mic was not quite eliminated, but almost nonexistent.
This was plug and play, so on an iPhone 15 I just plugged the USB-C adaptor in, went to the camera, and began recording video. The silver button on the front will mute an individual mic, and cause the light to go red when pressed. Simply press again to un-mute.
From the case to the adaptors, the build quality of each item feel premium and not plasticy. If I had to point out any negative, I do wish these had a stereo 3.5mm jack to turn these into more universal mics that could be used with camera inputs, howeverthis was not advertised as a feature so at the price point they seem very well done all around.

Conclusion in advance: K&F Concept 4G LTE surveillance camera Cell phone-capable camera at a great price. This is the first cell phone and solar camera I have ever bought. My reason for buying was to discover Blackjacks that like to come onto my property which is currently under development and currently houses a locked container. When I discovered that someone had tried to break in but luckily was stopped by the shipping container's puck lock, I had to do something to keep an eye on the property when I'm not around. A WiFi camera was out of the question as there is no WiFi available there. I wanted real-time deadbeat detection, which of course led me to this camera. Here are the highlights- 1) Extremely easy to install. I installed it on a utility pole about 20 feet tall as shown in the picture. I first mounted a flat wooden plate onto the round bar and then mounted the camera onto the plate. 2) Good picture in SD and great picture in HD. 3) Excellent motion detection and the camera will send you a message immediately. If you added a cloud service (very cheap) you can watch a replay of the event. 4) Good night vision and by activating the light via the app, the camera can see extremely far at night. It was surprisingly good. 5) No battery life issues. 6) I only have a 4G bar where the camera is installed, but I haven't had any reception problems. The speed could be better, but that's not because of the camera. Overall it was a good purchase and I will be buying another one for another part of the property. I would also like to point out that I installed a solar powered motion detection light over the camera to complement any video that might be captured at night. It's a great cheap combo.

This camera is perfect for our purposes. The picture quality is very good, the motion detection option allows multiple shots to be taken each time it is triggered, shows a series of photos of the moving subject. the house in bad weather while comfortably viewing photos from the camera and deleting a series of irrelevant photos as needed, It's great. It's convenient.

This voice recorder is truly a must have for me. I was amazed by its superior audio quality and noise-cancellation feature, which made every recording crystal clear, even in noisy environments. The password-protection feature is fantastic, providing an extra layer of security to each conversation I record. It's user-friendly too, although I did not initially know how to set up the password but they have an instruction video to help, and it was very easy to follow. The battery life is decent, and storage is ample for my needs. It is a bit more expensive compared to other digital recorders, but considering all the features it offers, it's worth every penny. It's a solid choice for anyone who values security and quality in their recordings.

The solar powered Surveillance camera is very good due to the portability. Detection is quick and video quality is good. Other reviews have had problems with the camera on their WiFi network. As long as there is a good strength WiFi signal and your upload speed is above 2 mbs there should be minimal problems.

bought this camera in pink color for my daughter 11 years old, the camera comes with 2 batteries, a charger and a 32GB memory card, more than enough to get the camera going. It is light wight, pocket size, easily fit into pocket to carry everywhere. It is a great beginner's camera, enough features to play around, such as self timer, anti shake, face detection, sharpness, ISO settings, white balance, exposure, continuous shots, face detection, smile capture, amazing such a samll camera packed with so many features/settings. Though the pink camera case looks plastic and cheap, other dark color may look better, nevertheless, it is a great bargin beginner's camera.

All in all a very good camera for the price!

Honestly, I can't find a better home security camera for the price
