Detector Concealed
statistics word problem?
To study people's ability to deceive lie detectors, researchers sometimes use the "guilty knowledge" technique. certain subjects memorize six common words; other subjects memorize no words. each subject is then tested on a polygraph machine as follows. the experimenter reads, in random order, 24 words: the six "critical" words (the memorized list) and, for each critical word, three "control" words with similar or related meanings. if the subject has memorized the six words, he or she tries to conceal that fact. the subject is scored a "failure" on a critical word if his or her electrodermal response is higher on the critical word than on any of the three control words. thus, on each of the six critical words, even an innocent subject would have 25% chance of failing. suppose a subject is labeled "guilty" if the subject fails on four or more of the six critical words. if an innocent subject is tested, what is the probability that he or she will be labeled "guilty"?
Chance of guilty response on word = 1/4,
chance of not guilty response = 3/4.
Denominator in all cases = 4^6 = 4096
Numerators are:
6 'unlucky' responses: 1^6 ... guilty response on each word.
5 'unlucky' responses: 6 * 3 = 18 (6 ways to pick the odd one out, times 3/4 probability on that one, times 1/4 probability on the others)
4 'unlucky' responses: 6C2 * 3^2 = 15 * 9 = 135 (15 ways to pick the two non-guilty responses, time 3/4 probability on each of those * 1/4 probability on the rest)
So overall the probability of being labeled guilty by random chance is
(1 + 18 + 135) / 4096 = 154/4096 = 0.0376

| | Mini Hidden Camera Detector $180 The Camera Finder reveals the presence of any camera, Wired or wireless, even if the power is off. Portable, the size of a Bic Lighter to fit in your pocket. Just look through the viewfinder and press the button. Any Hidden Camera is illuminated and its position revealed. Easy 3 Step CameraFinder Use Protect Yourself from Prying Eyes Camera Finder is an easy to use Hidden Camera Detector. Simply look through the viewing port and scan any room to reveal the exact location of concealed Wireless and Wired Cameras. Use it in dressing rooms or gym locker rooms to protect yourself from prying eyes. Give your loved ones peace-of-mind knowing their privacy has not been compromised. BrickHouse Security recommends the Camera Finder, the only device that works well and fits in your pocket, giving you portable protection. The Camera Finder Hidden Camera Detector/Locator is the most reliable, user-friendly technology on the market, allowing you to make sure that you are not being watched. It uses optical augmentation; a phenomenon whereby light reflected from a focused optical system, such as a Video Camera, is reflected along the same path as the incident light. If a Hidden Camera is illuminated and viewed with the Camera Finder, then a strong reflection from the target camera will reveal its position to the user. The Camera Finder takes advantage of this phenomenon by using a ring of ultra-bright LEDs arranged around a viewing port. When a user scans a room looking through the viewing port, a Hidden Camera appearing in the field of view will brightly reflect the light from the LEDs. To scan an area, simply look through the viewing port and depress the button to activate the LEDs. Slowly scan areas where Hidden Cameras are suspected and look for bright-reflected spots. Remember, most Hidden Video Cameras use Pinhole Camera Lenses, so the spot you are looking for could be small. If you see a suspected camera, move your vantage point slightly. If the location of the reflection moves as you move, then this is not a camera. If the location of the reflection does not move, then it is highly likely that you have discovered the optics of a Hidden Camera. Includes Camera Finder Camera Detector 2 AAA Batteries Instructions Size 4 1/2″ x 1 1/2″ x 3/4″ How it Works Operating Principle The Camera Finder Hidden Camera Detector/Locator is the most reliable and easy to use technology on the market for confirming that your private actions are not being watched. The Camera Finder's function is based on the principle of optical augmentation. This technical jargon refers to the phenomenon where light reflected from a focused optical system, such as a Video Camera, is reflected along the same path as the incident light. This means that if a Hidden Camera is illuminated and viewed with the Camera Finder Technology, then a strong reflection from the target camera will reveal its position to the user.

Surveillance Video: Walk-Thru Concealed Weapons Detectors
sneaking a camera in a concert...........?
ok this is a question for those of you who live in florida who have been to the cruzan amphitheater in west palm beach. i understand that its probably not the right thing to do but i want to sneak a video cam in. i have a realy compact video cam that can be easily concealed. i want to no if the theater has metal detectors, wands , some thing that could locate my camera. also what would they do if i wasw caught? would i get thrown out?? or would i just get it taken away. ( im seeing nickelback by the way if that makes any difference.) i doubt there will be many people able to ask this question but please answer!
is there any rule for the concert about camera's or phones ? if you have a pocket sized camera take it , if you believe it is to much of a risk , bump the settings up in your phone and use that with decent memory card in it it should be fine even if you use your phone, they wont question a phone
