In VIP security, counter surveillance is very important. Which of the following is/are essential for counter surveillance?

• 1. Try speeding up, and then slow down
• 2. Walk into a building and stop abruptly
• 3. Drop something to see if someone picks it up

Select the correct answer using the code given below :

[amp_mcq option1=”1 only” option2=”1, 2 and 3″ option3=”2 and 3 only” option4=”1 and 3 only” correct=”option2″]

The correct answer is B) 1, 2 and 3.

Counter-surveillance techniques aim to detect if someone is following or observing a VIP. All three listed actions are considered valid methods to potentially reveal surveillance.
1. Changing speed (speeding up and slowing down) forces a potential surveillant to adjust their pace, making their following behavior more obvious.
2. Entering a building and stopping abruptly allows the VIP (or security personnel) to observe who enters after them or reacts outside.
3. Dropping something can be a deliberate act to create a pause or cause a reaction from someone following closely, potentially revealing their presence or behavior.

These are examples of physical counter-surveillance tactics used to disrupt predictable patterns and force a surveillant to take actions that might expose them. Other techniques include making unexpected turns, using reflections, and being observant of recurring individuals or vehicles.

With regard to CCTV monitor, which one of the following statements is *not* correct ?

[amp_mcq option1=”Monitor should be placed in a curved configuration” option2=”The monitor screen should be tilted upward to avoid reflection of overhead lighting” option3=”If possible, stacking of monitors should be avoided” option4=”Screens should be placed in a sequence, providing logical continuity with relation to location of cameras” correct=”option2″]

The correct answer is B) The monitor screen should be tilted upward to avoid reflection of overhead lighting.

The statement that is *not* correct regarding CCTV monitor placement is tilting the screen upward to avoid reflection of overhead lighting. Tilting a screen upward would typically increase the angle at which light from overhead sources reflects into the operator’s eyes, worsening glare and reducing visibility. To avoid reflections from overhead lights, monitors should ideally be tilted slightly downwards or positioned to avoid direct light sources.

Correct practices for CCTV monitor placement often include arranging large arrays in a curve for better viewing angles (A), avoiding stacking to reduce neck strain and improve horizontal scanning (C), and arranging screens logically according to camera location to aid situational awareness (D). Reducing reflections is crucial for operator comfort and effectiveness, and tilting upwards achieves the opposite when lights are overhead.

Which of the following statements is/are correct ?

• In AK-47 Rifle, we use 7.62 mm ammunition
• INSAS Rifles use ammunition of 5.56 mm
• INSAS Rifle is shorter than AK-47 Rifle
• AK-47 Rifle is heavier than INSAS Rifle

Select the correct answer using the code given below:

[amp_mcq option1=”1 only” option2=”1 and 2 only” option3=”3 only” option4=”2 and 4 only” correct=”option2″]

The correct answer is B) 1 and 2 only.

Statement 1: The AK-47 rifle primarily uses 7.62x39mm ammunition. This statement is correct.
Statement 2: The INSAS (Indian Small Arms System) rifle uses 5.56x45mm NATO ammunition. This statement is correct.
Statement 3: The INSAS rifle (typically around 960mm) is generally longer than the standard fixed-stock AK-47 rifle (around 870mm). Therefore, this statement is incorrect.
Statement 4: The original milled-receiver AK-47 (~4.3 kg) is slightly heavier than the INSAS rifle (~4.15 kg with empty magazine). However, the more common stamped-receiver AKM (~3.1 kg) is significantly lighter than the INSAS. Without specifying the variant, the statement “AK-47 Rifle is heavier than INSAS Rifle” is not universally true and thus considered incorrect in this context, especially compared to common variants like the AKM. Given that statements 1 and 2 are definitively correct, and option B combines them, it implies that statements 3 and 4 are considered incorrect.

The INSAS rifle is the standard assault rifle of the Indian Army. The AK-47 and its variants are widely used globally. The difference in ammunition size (7.62mm vs 5.56mm) reflects different design philosophies regarding range, stopping power, and manageability.

In the context of Aviation Security, a matchbox comes under the category of :

[amp_mcq option1=”Explosive” option2=”Incendiary” option3=”Dangerous substance” option4=”Weapon” correct=”option2″]

The correct answer is B) Incendiary.

In aviation security, items are categorized based on the type of threat they pose. A matchbox contains matches, which are materials designed to ignite easily and rapidly burn. Such items are classified as incendiaries because they pose a fire risk.

Explosives are substances that detonate. Dangerous substances is a broad category that includes various hazardous materials, but incendiaries are a specific subcategory often listed separately or highlighted due to their specific fire hazard. While an incendiary device can potentially be used as a weapon, its primary classification based on its properties and the risk it poses (fire) places it under the incendiary category in aviation security regulations.

In X-BIS, what is meant by TIP ?

[amp_mcq option1=”Threat Identification Procedure” option2=”Threat Image Projection” option3=”Tested and Identified Packet” option4=”Test Identification Parade” correct=”option2″]

The correct answer is B) Threat Image Projection.

X-BIS stands for X-ray Baggage Inspection System, commonly used in security checkpoints. TIP in the context of X-BIS refers to Threat Image Projection, which is a software feature designed to enhance the effectiveness of security screening operators.

TIP works by superimposing artificial images of prohibited or dangerous items (threats) onto the real X-ray images of bags being screened. This allows the system to test and train operators by seeing if they detect these simulated threats. It helps maintain operator vigilance and identify training needs.
