delivered the opinion of the Court.
The appellants were convicted of violating the narcotic laws in the Criminal Court of Baltimore, before Judge James K. Cullen, presiding without a jury. Each was sentenced to imprisonment for a term of three years.
On this appeal the appellants contest the validity of the search warrant. They concede that the facts stated in the application for the warrant show probable cause but contend that those facts were illegally obtained. The facts were obtained by a police officer, inside a home with permission of the occupants, observing, with the aid of binoculars, activities occurring in a room in a house about ISO feet away. The observations were made from a window in the home in which the officer was located through an unobstructed window in the house under surveillance. The basis of the contention is that the use of the binoculars in such a manner for such a purpose violated the constitutional rights of the appellants.

The Supreme Court said in
Berger v. New York,
388 U. S 41,
“It is now well settled that ‘the Fourth Amend- ■ ment’s right of privacy has been declared enforceable against the States through the Due Process Clause of the Fourteenth’ Amendment. Mapp v. Ohio,367 U. S. 643 , 655,81 S. Ct. 1684 , 1691,6 L. Ed. 2d 1081 (1961). ‘The security of one’s privacy against arbitrary intrusion by the police — which is at the core of the Fourth Amendment — is basic to a free society.’ Wolf v. People of State of Colorado,338 U. S. 25 , 27,69 S. Ct. 1359 , 1361,93 L. Ed. 1782 (1949). And its ‘fundamental protections * * * are guaranteed * * * against invasion by the States.’ Stanford v. State of Texas,379 U. S. 476 , 481,85 S. Ct. 506 , 509,13 L. Ed. 2d 431 (1965).”
The attention of the courts has become directed more and more to questions involving the individual’s right of privacy by the development and refinement of means of communication, although the evils of eavesdropping were early recognized. “Eavesdroppers, or such as listen under walls or windows, or the eaves of a house, to harken after discourse and thereupon to frame slanderous and mischievous tales, are a common nuisance.”
Hochheimer, Law of Crimes and Criminal Procedure,
1st Ed., §740, p.452;
IV Blackstone, Commentaries,
§168. The telegraph provided a better method to “harken after discourse” by the surreptitious interception of messages. The telephone made it possible to eavesdrop by intercepting a telephone line and thus this method of “wiretapping” became a not uncommon practice as a commercial and police technique. The problem has become more acute by the development of sophisticated electronic devices. The use of these devices, commonly known as bugging, makes it possible to eavesdrop, as the Court said in
Berger, supra,
The first wiretap case before the Supreme Court was
Olmstead v. United States, 277
U. S. 438,
“This Court has never held that a federal officer may without warrant and without consent physically entrench into a man’s office or home, there secretly observe and listen, and relate at the man’s subsequent criminal trial what w7as seen or heard.” (emphasis supplied)
The Court affirmed
Goldman
by finding no occasion to re-examine it, but stated that it declined to go beyond it. In
Lopez v. United States,
If evidence of what was seen or heard is otherwise admissible, we think it clear that the determinant is whether such evidence was obtained by physical trespass or unlawful entry. 3 If, so, constitutional rights are violated, if not, constitutional rights are not violated.
We do not feel that
Berger v. New York, supra,
holding that a New York permissive eavesdrop statute permitted a trespassory invasion of the home, by general warrant, contrary to the command of the Fourth Amendment, compels a finding to the contrary, despite Mr. Justice Douglas’ statement in his concurring opinion that
Berger
“overrules
sub silentio Olmstead v. United States, 277
U. S. 438,
The police officer in the instant case was not physically trespassing on the premises under surveillance and there was no unauthorized physical penetration into the premises or actual intrusion into a constitutionally protected area. We find Goldman v. United States, supra, controlling, as we are unable to distinguish, with respect to the principle of law involved, between overhearing conversations with a detectaphone and observing activities with binoculars. We hold that what was seen by the police officer was not made inadmissible by trespass, unlawful entry or statutory prohibition, and that the use of the binoculars was not a violation of any constitutional rights of the appellants. By so holding, the observations of the police officer were proper to show probable cause for the issuance of the search warrant. Probable cause having been shown, the warrant was valid.
Judgments affirmed.
Notes
. However, in Berger v. New York, supra, at 1877, the Court mentions that “a combination mirror transmitter has been developed which permits not only sight but voice transmission up to 300 feet.”
. In 1934 Congress prohibited the interception, without authorization, and the divulging or publishing of the contents of wiretaps. 48 Stat. 1103; 47 U. S. C. §605.
