Question: Will it be able to detect cameras which are veiled behind a surface, like a mirror?
Document: Work just like the more expensive models I have not been able to work the video detection part of the unit but the everything else worked find.
Though it looks like a toy, it is fine for the price. The manual, as observed by others reviewers is a mess in Engrish..... You will not be James Bond, but can avoid wirelles mics and hidden cameras.
I got this as a little amusement for myself and tried it on several cameras and other devices but I can tell you now that it just feels like the cheapest thing ever made. I wouldn't be surprised if it was never actually designed to work but to just trick bored people into buying something that lights up. Do not buy.
It's a piece of juck that people make you pay a whole lot of money for when everything that has a shiny surface looks like it's bugged. Please stop selling junk!
yes it pick up my corded phone, wifi signal, other signals from electronics... but not from bugs "listening devices" or hidden cameras from frequency. "live camera" my personal thoughts.... feels like that a certain angle beeps and turn full red and 'ONLY buyers" will know lol sucks DO NOT BUY
This is a great gadget for detecting microwave transmitter/receivers from a cell phone, notebok with WiFi, a Wireless Modem or ? I bought this to make sure my room isn't being bugged, or my car dosn't have a hidden GPS tag. Yes I'm kind of paranoid, but you havn't lived my life. It's coated in gelskin, and has an audible or silent setting. It has earbuds and has an infrared light to detect hidden cameras. This works on the principle that glass reflects the light back to you.
It does detect a wide range of radio signals. I don't know about the infrared detector, I haven't tried that part of it. It looks like a toy, like a junior detective toy, but it does detect my wireless camera signals, router signals, wireless computer signals, etc.
She has no clue how to use use it and she is afraid of getting caught in the act, though she is the victim, so I only was able to test it on my own video surveillance equipment and it did in fact work very well in spotting my cams, though they are in plain sight.
This is an inexpensive detector that locates RF signals. Have not used it for hidden cameras. The product came complete and with fast shipping.
Although this item seemingly worked well in my home; since I didn't find anything to cause it to go off but did in a set-up scenario in another environment, I can only assume that it works well enough for my application. I haven't used it anywhere else yet to be able to formulate a more definitive opionion.
Answer: I would think so as when testing this device around my home it detected my cameras in various places of my home and detected a camera that was just on the other side of a wall in another room. The closer you get to something the stronger the alert is that comes from the device. It has worked well for me so far.
