Bryant Kinloch was charged with trafficking cocaine, trafficking heroin, and possession with intent to distribute heroin within proximity of a park after law enforcement obtained a search warrant and discovered cocaine and heroin at 609 A Pleasant Grove Lane in Charleston. Before trial, Kinloch moved to suppress the drugs, raising the following grounds to support his motion to suppress: (1) the search warrant affidavit was not sufficient to establish probable cause to search 609 A; (2) the good faith exception to the exclusionary rule did not apply; and (3) even if the affidavit were sufficient, law en*614forcement intentionally omitted exculpatory information, which, if included, would defeat probable cause. The trial judge suppressed the drugs, finding the search warrant affidavit was insufficient to establish probable cause. The Court of Appeals affirmed. State v. Kinloch, Op. No. 2012-UP-432, 2012 WL 10862443 (S.C.Ct.App. filed July 18, 2012). The State petitioned for a writ of certiorari, and we granted the petition.
Factual/Procedural Background
Law enforcement prepared an affidavit, setting forth the following facts in support of obtaining a search warrant for 609 A.
On January 2, 2008, law enforcement conducted surveillance of 609 A after receiving “numerous complaints about heroin and cocaine transactions” at 609 A “over the past several months.”1 During its surveillance, law enforcement observed two white males meet with a black male wearing a red shirt, red pants and red hat.2 The parties entered the residence for about “one minute,” and the white males exited the residence, walking in the direction of Highway 17. On three or four other occasions, law enforcement observed the black male in a red shirt exit the residence and meet unknown parties, with whom the black male in a red shirt engaged in quick “hand-to-hand” transactions. Law enforcement observed the black male in a red shirt counting money after the transactions as he returned to 609 A. During each transaction, the black male in a red shirt was accompanied by another male wearing a black puffy jacket. Law enforcement observed the black male in a red shirt walking into and out of the residence on several occasions. At around 5:00 p.m. that same day, law enforcement ob*615served the male in the black puffy jacket exit the residence and walk towards a gas station on Highway 17. The subject handed an unknown black male, later identified as Redondo Burns, a clear plastic wrapping in exchange for money. Law enforcement approached Burns, at which point he dropped a clear plastic baggy containing a white powdery substance, which tested positive for heroin. Law enforcement observed the male in the black puffy jacket return to 609 A.
Based on the above information, the magistrate issued a warrant to search 609 A for drugs and items related to the purchase and distribution of drugs. No supplemental testimony was taken.
Upon executing the search warrant, law enforcement recovered the following from 609 A: (1) twenty grams of heroin from Kinloch’s pocket; (2) two baggies each containing ten grams of white powder; (3) a one dollar bill containing a brown powder substance on the kitchen counter; (4) cocaine base on the kitchen counter; (5) a brown wrapper containing a green leafy substance on the kitchen counter; and (6) items suggesting Kinloch manufactured or distributed narcotics.
Kinloch moved to suppress the drugs, arguing the search warrant affidavit did not set forth sufficient facts to establish probable cause to search 609 A and thus, the search violated the Fourth Amendment.3 Specifically, Kinloch contended the suspicious foot traffic outside 609 A, coupled with finding drugs on Burns, a person who was never connected to the residence, was not sufficient to establish probable cause to search 609 A. Thus, Kinloch argued the search warrant affidavit was insufficient because there was not a sufficient nexus to connect the drugs that were recovered from Burns to 609 A
The trial judge granted Kinloch’s suppression motion, finding the affidavit was insufficient because the affidavit failed to link the drugs recovered from Burns to 609 A. The trial judge relied on State v. Gentile, 373 S.C. 506, 646 S.E.2d 171 (Ct.App.2007), and stated that while there was a lot of suspi*616cious activity outside 609 A, law enforcement only recovered drugs “some distance from 609 A” and that was not sufficient to establish probable cause to search the residence.
The State appealed, arguing the trial judge erred in finding the affidavit was insufficient to establish probable cause because in doing so, the trial judge improperly required the affidavit to establish with “near certainty” that drugs would be found at 609 A, rather than the proper “fair probability” standard. The State further argued the tips of drug activity outside 609 A, and law enforcement’s observance of “hand-to-hand” transactions outside the residence collectively were sufficient to establish probable cause to search 609 A. Thus, the State contended the trial judge’s suppression ruling should be reversed since the trial judge utilized an improper standard of review, and since a sufficient nexus was established between 609 A and Kinloch’s drug activity.
The Court of Appeals affirmed. The Court of Appeals cited “clear error” as the standard of review for determining whether the trial judge erred in finding the search warrant was not supported by probable cause. Kinloch, Op. No. 2012-UP-432 (S.C. Ct.App. filed July 18, 2012). However, the Court of Appeals then cited Gentile and parenthetically noted the magistrate in Gentile did not have a “substantial basis” for his probable cause determination because the search warrant affidavit failed to connect the evidence of drug activity to Gentile’s residence. Id.
Issue
Did the Court of Appeals err in finding the search warrant affidavit was insufficient to establish probable cause?
Law/Application
The Fourth Amendment protects against unreasonable searches and seizures. U.S. Const, amend. IV. A search or seizure does not violate the Fourth Amendment if it is authorized by a warrant that is supported by probable cause.4 *617Id.; see State v. Baccus, 367 S.C. 41, 50, 625 S.E.2d 216, 221 (2006), cert. denied, 555 U.S. 1074, 129 S.Ct. 733, 172 L.Ed.2d 735 (2008). A warrant is supported by probable cause if, given the totality of the circumstances set forth in the affidavit, there is a fair probability that contraband or evidence of a crime will be found in a particular place. Baccus, 367 S.C. at 50, 625 S.E.2d at 221 (citing Illinois v. Gates, 462 U.S. 213, 238, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983)).
In reviewing a magistrate’s probable cause determination, circuit court judges must determine whether the issuing magistrate had a substantial basis upon which to conclude that probable cause existed. Baccus, 367 S.C. at 50, 625 S.E.2d at 221; see also State v. Bellamy, 336 S.C. 140, 143-45, 519 S.E.2d 347, 348-49 (1999) (applying the fair probability standard and stating the duty of a reviewing court is to ensure the magistrate had a substantial basis for its probable cause determination). As the Supreme Court in Gates noted, reviewing a magistrate’s probable cause determination based on the “substantial basis” standard encourages law enforcement to seek a warrant, rather than conduct warrantless searches with the hope of relying on some other exception to the warrant clause. See Gates, 462 U.S. at 237, 103 S.Ct. 2317. If no supplemental testimony is taken, a magistrate’s probable cause determination is limited to the four corners of the search warrant affidavit. See, e.g., State v. Herring, 387 S.C. 201, 214, 692 S.E.2d 490, 497 (2009)
In finding the search warrant affidavit insufficient to establish probable cause, both the trial judge and the Court of Appeals relied on State v. Gentile, a case in which the following facts were insufficient to support the magistrate’s probable cause finding: (1) anonymous tips indicating a high volume of traffic frequented outside Gentile’s residence; (2) a citizen complaint regarding the smell of marijuana near the residence; and (3) the arrest of a visitor to Gentile’s residence, during which law enforcement recovered marijuana from the visitor. 373 S.C. 506, 514-18, 646 S.E.2d 171, 175-77 (Ct.App.2007).
Although Gentile is factually similar, it is not dispositive. Rather, here, unlike Gentile, the facts set forth in the affidavit establish that law enforcement received numerous complaints *618over the course of several months regarding drug activity at 609 A. After receiving those complaints, but prior to seeking a search warrant, law enforcement observed activity consistent with drug activity when they observed parties conducting “hand-to-hand” transactions outside 609 A and saw a man counting money as he returned to the residence. Based, in part, on this observation, law enforcement followed the man they had seen outside 609 A to a nearby gas station, where they saw this man hand another unknown man, later identified as Burns, a clear plastic wrapping in exchange for money. When law enforcement approached Burns, he dropped the clear plastic baggy, the contents of which tested positive for heroin.
We find based on these facts that the Court of Appeals erred in affirming the circuit court’s suppression ruling as the magistrate had a substantial basis for reaching his probable cause determination. See Baccus, 367 S.C. at 50, 625 S.E.2d at 221 (reviewing a magistrate’s finding of probable cause under the “substantial basis” standard of review). We reach this conclusion after acknowledging that independently each fact set forth in the search warrant affidavit is merely suspicious, but the totality of the circumstances — namely, the numerous tips indicating drug activity was probably present at 609 A and the subsequent surveillance of 609 A during which seemingly drug-related behavior was observed — distinguishes this case from Gentile. Likewise, we note that our decision today is based, in part, on the uncertainty as to the standard applied to review the magistrate’s probable cause determination. See Kinloch, Op. No. 2012-UP-432 (S.C.Ct.App. filed July 18, 2012) (reciting, erroneously, “clear error” as the standard by which it was reviewing the trial judge’s decision).
Accordingly, we reverse and remand with instructions that the circuit court proceed in a manner consistent with this opinion.5
