Hidden Spy Camera Detector

I recently purchased this and at first when i had my bluetooth and wifi on it didn't detect anything other than an increase in numbers. But when i turned off my wifi but left my bluetooth on it started to detected some areas . So I wanted to know if theres a difference when having your wifi turned on/off does it affect it and how accurate this is ?

As there was no free trial I went based off reviews and bit the bullet on the 299. Boy am I sorry. Not detailed At All. It keeps telling me there is a small device. But What is it? (example my phone, tablet, Etc.) The wired Camera Detector starts out at 59 and the only thing that drew a magnetic Spike was my doorbell camera. My other smaller cameras did not register, as I use these things as a test drive learning how to use the app. This app did not suit my needs as my neighbors are my problem, I suppose if I was worried about my partner in my own home it might show hidden devices. But for the general public areas I was sorely disappointed. Trying to figure out how to get out of this $2.99 as I haven't even had the app for 24 hours. 👎👎

Great device but dosent show how to upgrade
