Exam SY0-501 topic 1 question 348 discussion

Why isn't the correct answer B? A motion detector would sound off an alarm when it's triggered but without cameras you can't see who's committing theft. What if the motion detector goes off when someone is actually supposed to be there? With cameras you easily identify the thief. It has to be answer B.

i think because they said Detect not identify thats why

Guys Camera\s will record but it wont alert at anytime, however Motion detector even though its imbedded in an camera it will alarm, I remember using a camera system that turns the boundaries of a camera view red when a motion is detected (The core of the detection is the motion detector embedded in the camera) so answer is Indeed C.

answer is C. Motion detectors Motion detection—a motion-based alarm is linked to a detector triggered by any movement within an area (defined by the sensitivity and range of the detector),such as a room. The sensors in these detectors are either microwave radio reflection (similar to radar) or Passive Infrared (PIR), which detect moving heat sources.

Y'all are giving this way too much thought. The question states the need to detect theft, not identify the thief. (It doesn't even say the detection has to occur in real-time.) A. Biometrics -- Obviously not the correct answer. B. Cameras -- Can be monitored by a security guard or have its footage recorded for later review. These can easily be configured to monitor equipment and capture any theft that takes place. C. Motion detectors -- Detect motion, not theft. (I actually had moths set off the motion detectors at my office one night. I promise they weren't stealing anything.) D. Mantraps -- Used primarily to prevent "tailgating". They might detect theft if you're trying to carry out a 24" CRT monitor, but it won't help with smaller, easily concealable items. Answer is 'C'.

Folks, found something that certainly will ease our pain about the conflict :) First of all the correct answer is neither Cameras nor Motion detectors; it is exactly Mantraps. Many thanks to Meyers; here is the explanation he makes: ... Mantraps may also use additional security features, such as video cameras, body scanners, metal detectors, and even scales to compare weights when a person enters and exits a facility. This last measure might be employed to ensure that individuals are not stealing items from the facility on exit. ... (Mike Meyers’ CompTIA Security+ p. 406)

A theft is the act of stealing; a thief is the person who's stealing; the question asks us to choose a method to DETECT a theft; there's NOTHING in the question that specify we have to identify the thief. That said, we are again in front of another "coin-flip" CompTIA question , very vague, poorly worded and in this case also very unfair: notice that, they usually formulate the question saying "what's the BEST method to ... "; here they don't even say that: it's like they pretend there's ONLY one right method to choose from the given answer; but it's clearly wrong because nobody can deny that cameras and motion detection systems are BOTH valid methods to detect thefts so they are BOTH valid answers; if they had asked which is the BEST method (but they didn't), they should have given some more details about the scenario; what you choose to implement depends on factors that are NOT specified in the question, making impossible to determine what is the best answer between these two.

Detect is both in the question and the answer.

Lots of mixed answers. DETECT is both cameras and sensors. But would chose cameras if I want to know WHO is doing the theft. Someone might not be monitoring the feeds when the theft happens but with motion sensors detection would be 24*7 possible so C should be good

It should be B

Camera is the answer. The motion sensors would identify but not detect. Also there's gonna be a lot of false positives with the sensors since not every person is commiting a theft

C is correct by GCGA book... I dont get it but Motion Detection is considered detective control

Reconsidered: D Mantraps – Given: 1. datacenter equipment missing 2. CIO wants to DETECT theft (A) Biometrics - No (B) Cameras – DETECT in real time if actively monitored – or later by tape (C) Motion detectors – DETECT motion in real time – but will get a lot of false positives due to authorized personnel (D) Mantrap – DETECT and prevent theft – guard will search everybody leaving the data center - DETECTS stolen equipment on person or in bags, etc

C -- Definitions: detect is to discover as, to detect a crime or a criminal - while reveal is to disclose or show something hidden. Keyword is DETECT - motion detectors (C) would DETECT any activity – legitimate or otherwise - in the datacenter – so would require active monitoring to DETECT a theft as it was occurring. Not (B) Cameras – if actively monitored will REVEAL a theft immediately - otherwise later REVEAL – but not DETECT - the theft. https://comparewords.com/detect/reveal

detect means Motion detector or CCTV. However, the question doesn't mention CCTV, it mentions the Camera. What if the question means the Camera as normal camera not CCTV. So, the answer is Motion detector.

most useless question. all security camera systems have built in motion detectors. No company would just use motion detectors. i know its just minutia, but it's a poor question.

Cameras would be useless if there's something obstructing the view of the equipment in question. The only thing that would detect the theft of equipment unquestionably would be a motion detector, so the answer is C.
