Can a New York village install video cameras to monitor its public streets and sidewalks without a warrant?

Plain-English summary

The Village of Haverstraw wanted to install video cameras on its public streets and sidewalks to help its small police force keep an eye on local crime. The cameras would feed to monitors at the police station, the angles could be adjusted remotely, and the footage would be saved and potentially used as evidence in prosecutions. The Village Attorney asked whether the warrantless video surveillance violated the Federal or State Constitution or any state statute. The Attorney General's office said it did not, with several important conditions.

CPL Article 700 sets stringent warrant requirements for "video surveillance," but that statutory definition only kicks in when the observation would infringe on a person's reasonable expectation of privacy. People on public streets and sidewalks generally do not have a reasonable expectation of privacy in their visible activities. The Fourth Amendment "protects people, not places" (Katz v United States), but what a person knowingly exposes to the public, even in a public area, is not constitutionally protected. Under Ciraolo (warrantless aerial search of a fenced back yard) and Reynolds (warrantless aerial surveillance of property without no-trespassing precautions), what is visible to the public is fair game.

That permission has limits. First, no audio: any audio capture would be "mechanical overhearing of conversation" under Penal Law § 250.00(2) and subject to the eavesdropping warrant requirements. Second, cameras must not be aimed into the interior of residences. Third, even in public spaces, people can create temporary zones of privacy (Taketa), so each case is fact-specific. Fourth, the New York Court of Appeals has shown willingness to give the State Constitution broader scope than the Fourth Amendment (Scott rejected Oliver's flat "open fields" rule), and Bialostok confirms that CPL Article 700 will be construed sensitively to State constitutional rights, so a strict approach to electronic surveillance is the right working assumption.

Currency note

This opinion was issued in 1997. Subsequent statutory amendments, court decisions, or later AG opinions may have changed the analysis. Treat this page as historical context, not current legal advice. Verify current law before relying on any specific rule, deadline, or remedy mentioned here.

Common questions

Q: Why are public streets treated differently from private spaces for surveillance?
A: The two-part Katz test asks whether a person actually expected privacy and whether society is prepared to recognize that expectation as reasonable. People walking on a public street know they are visible to anyone passing by, so they do not have, and society does not recognize, a reasonable expectation that their visible activities will be private.

Q: What happens if the cameras catch the inside of a residence?
A: That is the constitutional boundary line. Filming the interior of a home or other private space would invade a recognized privacy interest, and absent a warrant, would violate the Fourth Amendment and Article I, § 12. The Village told the AG's office its cameras would not be aimed at residences and could be programmed to prevent that capability; the opinion took that representation at face value.

Q: Why can't the cameras record audio?
A: Audio recording of conversations is "mechanical overhearing" under Penal Law § 250.00(2), which is part of the eavesdropping statute. Eavesdropping requires a warrant under CPL Article 700, which has stringent issuance requirements. The Village's video-only setup avoided the audio warrant requirement entirely.

Q: Does this opinion mean any public-space video surveillance is automatically OK?
A: No. The opinion explicitly cautions that courts make case-by-case privacy assessments. Cameras aimed at sensitive locations (a doctor's office entrance, a domestic violence shelter), with persistent close-up zoom, or with facial-recognition or tracking capabilities, raise harder questions. The opinion's reasoning was tied to ordinary visible activity on public streets.

Q: Could the footage be used as evidence in court?
A: The opinion did not rule on admissibility, but the implication is yes for warrantless footage of public-space activity. As long as the surveillance itself did not violate the Constitution or statute, evidence derived from it is generally admissible.

Q: How does New York treat privacy more strictly than federal law?
A: People v Scott rejected Oliver v United States's flat rule that "open fields" outside the curtilage receive no Fourth Amendment protection, holding that New York's Article I, § 12 protects reasonable expectations of privacy even outside the curtilage if the owner has shown an intent to keep the area private (no-trespassing signs, fencing). People v Bialostok required a warrant for a pen register with mechanical-overhearing capacity even when that capacity was not active. The pattern is a state constitution sensitive to the "insidiousness of electronic surveillance."

Background and statutory framework

The framework here is overlapping. The Fourth Amendment to the U.S. Constitution and Article I, § 12 of the New York State Constitution prohibit unreasonable searches and seizures. The reasonable-expectation-of-privacy test from Katz v United States governs whether government conduct counts as a "search." Public-space conduct generally does not.

CPL Article 700 layers on a statutory warrant regime for eavesdropping (audio interception of conversations) and "video surveillance" (visual observation by law enforcement that would otherwise infringe a reasonable expectation of privacy). The Article 700 warrant requirements only attach when there is an underlying privacy interest. Penal Law § 250.00 defines the underlying offenses (eavesdropping, mechanical overhearing) that the warrant regime guards.

For ordinary outdoor video surveillance of public streets and sidewalks, the layered system produces the result the AG's office reached: no warrant required, no statutory violation, as long as the surveillance stays in the public space, does not capture audio, and does not breach reasonable expectations of privacy in particular cases.

Informal Opinion
No. 97-47

Dear Mr. Hood:
You have asked whether the village may install video
surveillance cameras at several locations to monitor the public
streets and sidewalks. You state that the cameras will be
operated from the village police station where monitors will be
located, and that videotape recordings of the cameras'
observations will be maintained. In a telephone conversation,
you further advised that the camera angles can be adjusted from
the station, that the police will be instructed not to position
the cameras to film the interior of residences and that it may be
possible to program the cameras so that such filming cannot be
done. You informed us that the cameras have no audio component
and will not be used to decipher speech. You also note that the
police force plans to use videotapes from these cameras as
evidence in the prosecution of any crimes revealed during video
surveillance. The village hopes that use of the cameras will
enable its small police force to reduce local crime at a
reasonable expense. You inquire whether video surveillance of
public streets and sidewalks is constitutional and permitted by
statute.
We are aware of no State law that expressly prohibits video
surveillance of public places by a municipality's police force as
you describe it. However, Criminal Procedure Law Article 700
establishes stringent requirements for the issuance of
eavesdropping and video surveillance warrants. CPL § 700.05(9).
The statute provides that a district attorney or the Attorney
General may apply for a warrant, specifies to whom the
application may be made, and lists the "designated offenses" that
may be the subject of an application. Criminal Procedure Law
§§ 700.05 (4), (5), (8); 700.10.

Article 700 also defines "video surveillance" to mean
the intentional visual observation by law
enforcement of a person by means of a
television camera or other electronic device
that is part of a television transmitting
apparatus, whether or not such observation is
recorded on film or video tape, without the
consent of that person or another person
thereat and under circumstances in which such
observation in the absence of a video
surveillance warrant infringes upon such
person's reasonable expectation of privacy
under the constitution of this state or of
the United States. Id., § 700.05(9).
Article 700 defines "eavesdropping" to include wiretapping,
mechanical overhearing of conversation and the intercepting or
accessing of an electronic communication as those terms are used
in Penal Law § 250.00. "Mechanical overhearing" means the use of
a device for the intentional overhearing of a conversation
without the consent of one of the parties by a person not
present. Penal Law § 250.00(2). Any video surveillance that
includes an audio component would fall within this definition and
the warrant requirements for eavesdropping would apply. (See,
Preiser, Practice Commentaries, McKinney's Criminal Procedure Law
§ 700.05, p 562 [1995 ed]).
Under the above statutory definition, a warrant is required
for video surveillance without an audio component only when the
surveillance would infringe upon a reasonable expectation of
privacy. Therefore, we must analyze whether persons videotaped
while on public streets and sidewalks have a reasonable
expectation of privacy.
Courts have analyzed a person's reasonable expectation of
privacy in interpreting the Fourth Amendment to the Federal
Constitution and Article 1 § 12 of the New York State
Constitution, which both provide that "the right of the people to
be secure in their persons, houses, papers and effects, against
unreasonable searches and seizures, shall not be violated . . .".
In Katz v United States, 389 US 347 (1967), the
United States Supreme Court held that electronic interception of
an individual's telephone conversation without a warrant is
unconstitutional, even though the defendant had placed the calls
from a public telephone booth. In so holding, the Court reasoned
that ". . . the Fourth Amendment protects people, not places.

What a person knowingly exposes to the public, even in his own
home or office, is not a subject of Fourth Amendment
protection. . . . But what he seeks to preserve as private, even
in an area accessible to the public, may be constitutionally
protected." 389 US at 353 (citations omitted). In his
concurring opinion, Justice Harlan stated what has become known
as the Katz rationale:
My understanding of the rule that has emerged
from prior decisions is that there is a
twofold requirement, first that a person have
exhibited an actual (subjective) expectation
of privacy and, second, that the expectation
be one that society is prepared to recognize
as "reasonable." Thus a man's home is, for
most purposes, a place where he expects
privacy, but objects, activities, or
statements that he exposes to the "plain
view" of outsiders are not "protected"
because no intention to keep them to himself
has been exhibited. On the other hand,
conversations in the open would not be
protected against being overheard, for the
expectation of privacy under the
circumstances would be unreasonable.
Although the Court has not ruled directly on warrantless
videotaping of public streets and sidewalks, it has continued to
hold that what is knowingly exposed to the public is not
protected by the Fourth Amendment. In California v Ciraolo, 476
US 207 (1986), for example, a divided Court (5-4) held that a
warrantless aerial search of a fenced-in back yard did not
constitute a Fourth Amendment violation. The Court noted that
the officers viewed the property from public navigable airspace
and stated that the Fourth Amendment does not preclude a police
officer from making observations from a public vantage point
where the officer has a right to be present and that renders the
observed activities clearly visible.
In United States v Taketa, 923 F2d 665 (9th Cir 1991), the
Ninth Circuit held that warrantless videotaping of state and
federal agents in the state agent's office violated their
reasonable privacy interests and that introduction of the
videotapes into evidence constituted reversible error. In so
holding, the court reasoned that it must apply Katz and analyze
whether the person searched had a subjective expectation of
privacy and whether that interest is one that society is prepared
to recognize as reasonable. The court stated:

4
Video surveillance does not in itself violate
a reasonable expectation of privacy.
Videotaping of suspects in public places,
such as banks, does not violate the fourth
amendment; the police may record what they
normally may view with the naked eye.
Persons may create temporary zones of privacy
within which they may not reasonably be
videotaped, however, even when that zone is a
place they do not own or normally control,
and in which they might not be able
reasonably to challenge a search at some
other time or by some other means.

See also, McCray v Maryland, 581 A2d 45 (Md App 1990), cert
denied, 586 A2d 14 (Md 1991) (warrantless video of defendant
crossing street properly admitted into evidence; no justified
expectation of privacy is violated by videotaping activity
occurring in full public view); People v Milom, 75 AD2d 68
(1st Dept 1980) (no justified expectation of privacy as to
incriminating conduct that occurs in public area of restroom
rather than inside stalls; visual surveillance of public area did
not require warrant).
The New York Court of Appeals also has not ruled on the
propriety of warrantless videotape surveillance of individuals in
public places. It is noteworthy, however, that the Court of
Appeals has, in other circumstances, held that the State
Constitution affords greater protection than the Fourth Amendment
does. In People v Scott, 79 NY2d 474 (1992), for example, the
Court held that the ruling in Oliver v United States, 466 US 170
(1984), does not adequately protect fundamental State
constitutional rights. Accordingly, the court rejected the
Oliver holding that in areas outside the curtilage an owner of
"open fields" enjoys no Fourth Amendment protection.
Scott involved police entry onto rural property of the
defendant's that was posted with "No Trespassing" signs. The
Court first noted that Oliver is inconsistent with the analysis
in Katz. 79 NY2d at 485. The Court then rejected the Oliver
Court's categorical holding that an expectation of privacy in
land outside the curtilage is not one that society is prepared to
recognize as reasonable, because it does not adequately preserve
fundamental rights of New York citizens. The Court stated that
it consistently had applied the Katz principle that the
constitutional provisions protect people and not particular

5
places, and that the Oliver Court's holding would subvert
New York's acceptance of the principle that the Constitution
protects an individual's reasonable expectation of privacy.
Compare, People v Reynolds, 71 NY2d 552 (1988), in which the
Court held that warrantless aerial and ground surveillance of the
defendant's property did not violate the State Constitution. The
Court concluded that the owner had no reasonable expectation of
privacy in open fields and woods when she had taken no
precautions, such as putting up fencing or "no trespassing" signs
to exclude the public. The Court stated that "conduct and
activity which is readily open to public view is not protected".
71 NY2d at 557.
In People v Bialostok, 80 NY2d 738 (1993), the Court held
that a pen register that had the additional capacity to monitor
conversations should be treated as an eavesdropping device under
the Criminal Procedure Law, so that a warrant was required for
its use, even when the monitoring function was not activated. In
so holding, the Court stated that it has "consistently recognized
the 'insidiousness of electronic surveillance'" and made plain
that it will construe CPL article 700 in a way that is "sensitive
to the constitutional guarantees against search and seizure that
the statute seeks to protect." 80 NY2d at 704.
Under the rationale of these cases, it appears that,
generally, a person on a public street or sidewalk would not be
held to have a reasonable expectation that his or her actions
would be private, in the sense of being free from observation.
Accordingly, warrantless video surveillance of such areas does
not, per se, violate existing standards under the Federal or
State Constitution or State law. We caution, however, that
courts have held that the constitutional provisions protect
people, not places, and have applied a strict construction of the
Criminal Procedure Law provisions governing electronic
surveillance. Accordingly, the courts make a case-by-case
analysis as to an individual's reasonable expectation of privacy.
The Attorney General renders formal opinions only to
officers and departments of State government. This perforce is
an informal and unofficial expression of the views of this
office.
Very truly yours,

SIOBHAN S. CRARY
