If you live in Surprise, you already know how few ways there are to get anywhere. Bell Road runs east and west. Grand Avenue (US 60) cuts diagonally toward Phoenix. Loop 303 runs along the eastern edge. In the growing north and west parts of town, 163rd Avenue is still the main road out. The person you’re worried about almost certainly drives some version of those same few miles every day.
That’s what we build a surveillance plan around. Before anyone sits in a car billing hours, the route and the time window get mapped. Field time lands on the stretches of the day that matter, not on whole days of waiting to see what happens. For you, that means a bill that follows real work and a record you can use: time-stamped video, photos, and a written log of what was seen and when.
It also means a straight answer if nothing turns up. A clean result is sometimes exactly what you needed to know, and you’ll know it came from a plan and not a guess.
Quantum Investigations is veteran-owned and run by Jeff Penrod, a former Phoenix Police officer and military veteran. We’ve been working cases for 20+ years, and Jeff is the person you talk to when you call.
Here’s where we are, plainly: we have offices in Phoenix and Mesa, and we cover Maricopa County, including the Northwest Valley and Surprise. What matters on a case here is how the work gets documented. Police and military backgrounds mean logging times, keeping video intact, and writing reports an attorney or a Maricopa County court can work with. Our investigators can also testify about their methods if your case reaches a hearing.
Every investigator in Arizona must be licensed through the Arizona Department of Public Safety, and you should check ours before you hire anyone. The DPS lookup takes a couple of minutes. Then call. The consultation is free, confidential, and available day or night.
It starts with a call to Jeff. You tell him what you know: where the person lives, where they work or go, and which days things seem to happen. He’ll tell you honestly whether covert surveillance in Surprise fits your situation, or whether a background check or something else would get you further.
If it fits, you get a written scope before any field work. It spells out the hours you’re authorizing, how updates reach you, and which costs are billed separately, like mileage. Then comes the part most people never see: the route gets mapped first. Where does the day start, which road does it funnel onto, and when? Bell Road, Grand Avenue and Loop 303 carry most of that traffic, so the window that matters is often narrower than you’d expect.
Local conditions shape the plan. From June through September, hours in a parked vehicle are hard on anyone, so blocks get timed instead of stretched. February and March spring training at Surprise Stadium puts crowds around central Surprise and changes where traffic backs up.
Field work happens from public view. You get updates along the way and a written report with time-stamped video and photos at the end.

Every engagement is built around what you need documented. There are no preset packages, and the scope is written around your case. For many Surprise families that case is child custody: whether a parenting schedule is being followed, who’s present at exchanges, and what a routine looks like between a neighborhood like Surprise Farms or Marley Park and a workplace. Infidelity work follows where someone goes and who they meet, from public view. Employers and insurance carriers use the same private investigator surveillance for workers’ comp claims.
Surprise has another kind of case too. About one in five residents is 65 or older, and The Grand (formerly Sun City Grand), Arizona Traditions and other active-adult communities are home to many of them. When an adult child lives far away and worries about a new companion, a caregiver or a contractor with too much access, video surveillance can be paired with background checks and asset searches.
Whatever the case, the deliverable is the same: time-stamped video, photos, and a written log. So are the limits. We don’t trespass, record inside private spaces, or put trackers on a vehicle you don’t own. Drone recording of people at home is limited by Arizona privacy law, so don’t count on it as a shortcut.
Across Arizona, most agencies bill hourly plus expenses. Standard surveillance generally runs $75 to $150 per hour, and complex or specialized cases run $150 to $250 per hour. A retainer is common too, typically between $500 and $2,000, with mileage, equipment and database fees billed separately.
What moves the number in Surprise is mostly distance and timing. The city covers about 110 square miles, so a subject who has to leave a north or west neighborhood by way of 163rd Avenue and then cross the Valley to a job adds miles and hours. A second investigator roughly doubles the cost, and multi-day coverage adds up fast.
That’s why we map the route before field time is billed. When you call about a private surveillance investigator near Surprise, Jeff will go over the likely hours and scope in writing, so you’re approving a plan instead of an open tab.
Yes, as long as the investigator is licensed and stays inside the law. In Arizona, working as a PI without a license from the Department of Public Safety is illegal. You can look up any license on the DPS site before you hire, and you should do that no matter who you call.
Filming someone in a public place is lawful, and so is observing from a public road. What isn’t lawful: trespassing, recording people in private settings like the inside of a home, intercepting conversations you aren’t part of, and stalking. In a Surprise neighborhood, that means an investigator can be on a public street but not on someone’s property. A homeowners association’s rules don’t change what can be seen from a public road, but they don’t give anyone permission to cross onto private property either.
This is general information, not legal advice. Your attorney can speak to your specific situation.
Only on a vehicle you own. Putting a tracker on a car that isn’t yours can lead to civil and criminal trouble in Arizona, and it can be used as evidence of stalking against you. An investigator who offers to do it covertly is putting you at risk, and that’s a good reason to keep looking.
You don’t need one to get useful results in Surprise. So much of the day funnels onto Bell Road, Grand Avenue (US 60) and Loop 303 that a mapped route and a well-timed follow can show you the same pattern lawfully, with video and photos you can actually use. If the vehicle is yours, such as a car titled in your name, talk with Jeff and your attorney before anything gets installed.
Your consultation with Jeff is confidential, and nothing about the call reaches the person you’re worried about. The real risk is the subject noticing someone watching, and that’s where training counts. Our team comes from Phoenix PD and military backgrounds, and staying unnoticed is part of the job.
Surprise makes this harder than most places. It’s a neighborhood-centered town, and the same faces turn up at the park, the school and the grocery store. A subject who drives the same few miles of Bell Road every day will notice a car that keeps appearing. That’s why a friend or relative doing it for you tends to get spotted, and it can create stalking exposure for you. A planned approach varies when and where the investigator is, so nothing repeats.
Nobody can promise you won’t be noticed, and anyone who does is selling you something. If it’s your biggest worry, say so on the call and you’ll get a straight answer.
One night rarely settles anything. Plenty of cases need several days, because people don’t do the same thing every day. If your case hinges on one activity, coverage may need to land on the days it usually happens. Your own notes help here: the days you’ve noticed, the times that don’t add up.
In Surprise, a predictable commute helps. A few arterials carry most of the traffic, so the window worth watching is often narrow. Summer heat works the other way. From June through September, long stretches in a parked vehicle are hard to sustain, so coverage gets split into shorter, well-timed blocks. Spring training in February and March adds crowds around central Surprise that can change timing too.
No honest investigator can promise something will happen. If nothing does, you’ve still learned something, and you’ve paid for a plan rather than a guess. Jeff will tell you up front if he thinks the hours you’re considering won’t be enough.
Yes to both, from public view and within Arizona law. For custody, we can document whether a parenting schedule is being followed: arrivals and departures, who is present at exchanges, and routines on activity days. Dysart Unified serves nearly all of Surprise, so school-day patterns are often part of the picture. The focus stays on the adults and the schedule, not the children. You get time-stamped video, photos and a written log. A Maricopa County family court may consider it, but no one can promise how a judge will rule, and your attorney decides how to use it.
For a parent in The Grand (formerly Sun City Grand), Arizona Traditions or another active-adult community in Surprise, the question is usually who has access: a new companion, a caregiver, a contractor. Observation from public view can be paired with a background check or asset search. It can’t include a hidden camera inside someone’s home without the owner’s lawful consent. If you’re worried about a parent, call and talk it through. The right first step isn’t always surveillance.
