Electronic Surveillance Techniques Flashcards
What is Electronic Surveillance?
- Any type of electronic equipment that can be used to monitor and record events
- equipment used to gather oral or written communications
- including video or image capture
What are reasons to use Electronic Surveillance equipment ESE?
- gather evidence of violations of Federal Law
- protecting the safety of undercover agents and informants
- fulfilling other compelling investigative needs
What are audio recorders used for?
Evidence gathering
What are the 2 types of audio intercept devices?
- A recorder
2. Transmitter
What is the primary use of a recorder?
Collecting evidence
what is the primary use of a transmitter?
officer safety
What are the 2 types of tracking systems?
- Global Positioning System (GPS)
2. Radio Frequency beacon (RF beacon)
What are the 2 types of GPS trackers?
- Memory tracker
2. Live tracker
What are the 2 types of video surveillance system available? What types?
- Overt
- Covert
Fixed or mobile
wired or wireless
what can be a great asset in an investigation?
Closed Circuit TV Systems (CCTV)
What are sensor activated CCTV systems?
Recording starts and stops in response to a sensor such as seismic, magnetic, active or passive infrared
Why are electronic counter measures used by the “bad guy”?
to detect or thwart electronic surveillance
what must undercover operatives know about operating in an area in which audio intercept equipment is being used?
the limitations and problems which are inherent to use of such equipment
What are some short term duration considerations?
- Type of equipment
- meeting site(s)
- Personnel requirements to ensure safety
Long term duration considerations
- type of equipment needed
- equipment is more likely to fail the longer it is used
- environmental changes
- power sources, plans for charging batteries
regardless of whether the operation is long or short term what is needed to be conducted?
A site survey
What area is preferred for ESE?
a quiet open area
In audio intercept what should always be taken into consideration?
“center of the conversation”
Before a consensual recording operation a statement made on a digital device to authenticate its purpose is known as ?
A Preamble
What is the minimum information suggested when conducting a preamble?
- Name of agent/ agency
- subject(s) name
- date and time
- purpose of recording
What is the main reason a body worn audio recorder is preferred to gather audio evidence versus an RF transmitter?
• Quality of Recording
What is a legitimate reason to use Electronic Surveillance Equipment (ESE) during a Federal criminal investigation?
- Officer Safety
* Gather Evidence
Prosecutors expect evidence obtained
through electronic surveillance to
provide them with_____________.
• Irrefutable proof.
What are the 3 capabilities of Electronic
Surveillance?
- Electronic Audio & Aural wire intercept
- Video surveillance
- Electronic Tracking
What are the 2 types of Electronic Tracking?
- GPS Tracking
* Radio Direction Finding (RF Beacon)
When installing a body wire transmitter or room bug where should the microphone be placed?
• At chest level as close to the center of
conversation as possible.
What meeting locations will afford your team the best opportunity to monitor (hear) your conversation with the subject?
• A quiet open area affords the team the best opportunity to monitor (hear) your conversation
Who approves or denies an agent’s request to conduct one-party consensual audio monitoring?
• Approval for consensual monitoring must come from the head of the agency or his/her designee.
A statement that identifies the agent, agency, subject, date, time and the purpose of the recording is known as the___________.
• Preamble
Which of the following pieces of information should never be included in the preamble?
• The type of recording or transmission equipment used and where it is concealed.
A termination report about the use of Electronic
Surveillance Equipment (ESE) to perform
consensual monitoring will contain?
• The number of times interceptions (i.e.,
monitoring) corroborated the violation(s) under investigation
What is a protocol for handling evidentiary recordings?
• Enter recordings into evidence according to agency
policy
Before using ESE to perform consensual audio monitoring, the case agent must obtain authorization from his her agency. If face-to-face consensual audio monitoring is planned, the case agent will also contact an______________.
• AUSA - The AUSA must advise that the proposed consensual is legal and appropriate
