I hid 4 cameras in the room and tested it with this gadget, it found all of them. I also tested the wireless network interference function, and it really made my 2.4G network unusable, and it had no effect on the 5G WiFi signal. We are very satisfied with it.

Bought it for the wireless blocking feature and I got this to check out area's around my vacation property.
I tested it on my own cameras to get a feel for it and then walked around. I like the silent ability and its battery life is decent.
For the price you cant go wrong.

The Boya Omic Wireless Mic is an impressive and cost-effective option that continually improves over time, now featuring a convenient charging case and significant sound enhancements. Compatible with computers, Android/iOS devices, and more, it's perfect for content creation, live streaming, Vlog filming, and mobile journalism. With outstanding sound quality, adjustable noise reduction, and an impressive wireless range of up to 50 meters, it ensures clear audio and flexibility. The portable system also has built-in rechargeable battery with up to 5 hours of runtime, extendable to 20 hours with the charging case, which supports wireless charging for added convenience.

Can't fault it easy to install. I haven't put the reversing camera in yet or wired that up. Part from that the picture quality is excellent and its worth every penny.

I had been looking for a dash cam for a while. So when I saw the SSONTONG A9 gave me the front/rear and reversing all in one I ordered one straight away and at about the same price as a front only camera. The resolution of the picture on screen is excellant both in datime and night. it was also easy to install.

Love the crispy and clear video,love how easy it was to install and being wireless was a must.I am able to see the cameras over my phone data and am only seeing them if am on WiFi.Over all I think is a great product so far!!

Have used it a few times now to record videos of cars and works very well.
