A detached garage or backyard shed holds some of the most valuable things on a property: cars, bikes, tools, lawn equipment, generators, ladders and sometimes a workshop. It is also the part of the property farthest from the house, out of earshot and often out of sight from the street. Power and internet are not always there. Burglars know all of this. This guide explains how to secure a detached garage and backyard shed: the doors and locks that matter, how to light the area, where cameras go, how to get power and data out to an outbuilding, when wireless or solar makes sense, how to stop tampering and what a practical plan costs.
This is general information. Electrical work should follow code and be done by qualified people. Check local rules and your insurance policy.
1. The Short Version
| Item | Approach |
|---|---|
| Doors and locks | Solid doors, quality deadbolts or padlocks, reinforced hinges |
| Windows | Locks, film or covers; limit visibility of valuables |
| Lighting | Motion lights covering doors and approaches |
| Cameras | Outside covering doors; optionally inside |
| Power and data | PoE with buried conduit, or wireless/solar/cellular |
| Tamper resistance | High mounts, vandal housings, alerts for offline |
| Valuables | Engrave, photograph, store smartly |
2. Why Outbuildings Are Targets
They are quiet, dark and usually have weaker security than the house. Tools and equipment are easy to sell. Garage doors can be forced or opened with a stolen remote. Sheds often have padlocks that can be cut in seconds. Because the building is detached, a thief can work without entering the house or setting off interior alarms. Our guide on securing a Long Island colonial with a long driveway covers layered approaches for larger properties.
3. Doors and Locks
Cameras record; locks resist. Start with the physical barriers. A solid-core or metal service door with a quality deadbolt, a reinforced strike plate and long screws is far better than a hollow door with a basic latch. Overhead doors should have working locks or slide bolts, and an opener with a rolling code. Remove the garage remote from cars parked outside. For sheds, use a hardened padlock with a shielded shackle and a heavy hasp bolted through the door, not screwed into thin trim. A smart lock can give you logs and temporary codes.
4. Windows
Cover or frost windows so people cannot see the contents. Add locks. Consider security film on glass. Windows near doors should not allow a thief to reach in and unlock. Keep ladders, bikes and tools out of sight. A camera that sees the windows shows if someone peers in.
5. Lighting
Motion-activated lights at the garage door, service door and shed make an approach visible and improve camera footage. Place lights high enough to resist tampering and angled to avoid blinding cameras. Solar lights are an option where there is no power, though winter performance is weaker. Our guide on lighting for night cameras explains placement.
6. Camera Placement
Place cameras outside, covering the doors, the driveway apron and the approach from the yard. A camera on the house aimed at the garage can add a second view. Inside, a camera pointed at the door and the most valuable items helps if someone gets in. Mount high enough to be out of reach but low enough for faces. Our local pages for home camera installation in Suffolk County and security camera installation in Staten Island describe typical setups.
7. Power and Data to an Outbuilding
A camera needs power and a network connection. Options:
- PoE over buried Ethernet in conduit from the house, with surge protection at both ends. Reliable and secure; Ethernet is limited to 100 meters.
- A power circuit and Wi-Fi access point at the outbuilding, installed by an electrician and installer.
- Wireless bridge between the house and outbuilding for longer or hard-to-trench distances.
- Solar-powered cameras with local storage or cellular; see our guides on solar cameras and cellular cameras.
Trenching and conduit have code requirements; hire qualified professionals. Our guides on outdoor cabling and conduit, and surge protection explain the details.
8. Tamper Resistance and Offline Alerts
Thieves sometimes try to defeat cameras before entering. In April 2026, according to a May 2026 report on longisland.com, Nassau County police said investigators in a North Valley Stream burglary found that the victim's cameras had been repositioned and their lenses covered with tape, internet wiring had been cut and a signal jammer was found. That was a house, not a garage, but the same tactics can be used anywhere. Mount cameras out of easy reach, use vandal-resistant housings, set alerts for offline cameras and tampering, and record locally so cut internet does not erase evidence.
9. Cellular and Local Recording
For outbuildings, cameras with local storage (SD cards or a recorder) keep recording when Wi-Fi is cut. A cellular option adds an alert path. Check that offline alerts work and that clock settings are accurate. Our guide on what happens when the internet goes out explains behavior during outages.
10. Storing Valuables Smartly
Do not leave expensive tools and bikes in plain sight. Use a heavy-duty cabinet or locking storage within the garage. Chain bikes to a ground anchor. Engrave tools with your name or a code and photograph serial numbers. Record serial numbers in a list and keep it with your insurance papers. Mark generators and mowers and chain them to a fixed point. If the building has a window or glass door, use blinds or film.
11. Insurance
Homeowner's policies often limit coverage for outbuildings and contents, and may have sublimits for tools or business equipment. Ask your agent what is covered, what documentation they need and whether cameras or alarms earn discounts. The New York State Department of Financial Services publishes consumer information on homeowners insurance at dfs.ny.gov. Photograph contents and keep receipts.
12. Home Businesses and Workshops
If you run a business from a garage, such as a contractor with tools and materials, the loss from a break-in can be substantial and may fall outside a homeowner's policy. Talk to your insurer about business coverage and consider stronger measures: reinforced doors, alarms, cameras with alerts and professional monitoring; see our guide on professional monitoring vs. watching your own cameras.
13. Cost
Planning ranges in 2026: two exterior cameras on a garage with power and network, $700 to $1,800; trenching and conduit, often $15 to $40 per foot depending on conditions; wireless bridge, $300 to $1,200; solar camera, $250 to $900; motion lighting, $100 to $400; smart lock, $150 to $500; four-camera system for house and garage, $1,600 to $3,800. These are planning ranges, not quotes.
14. A Second Data Point
NYPD reported burglary down 19.5% citywide in May 2026 compared with May 2025 (NYPD). Trends help but do not protect your property. A detached building with good doors, lights and a camera is simply harder and riskier to approach than one without.
15. Questions to Ask Your Installer
- How will you power and connect cameras at the garage?
- How will you protect cables against surges and weather?
- How will you detect tampering and offline cameras?
- Do I need cameras inside as well as outside?
- Should I use solar or cellular cameras?
- What do you recommend for the doors and locks?

16. A Hypothetical Plan
A Staten Island homeowner has a detached two-car garage with a workshop and a shed at the back of the lot. The installer trenches conduit with Cat6 and power to the garage, installs two exterior cameras with motion lights, a vandal-resistant camera inside covering the workbench, a heavy hasp and shielded padlock on the shed, and a small solar camera on the shed that records to a card and sends offline alerts. A UPS protects the recorder in the house. Tools are engraved and photographed for insurance.
17. Seasonal Checks
Each season, test locks, lights and cameras. Clean lenses and trim vegetation. Check conduit access points, seals and surge protectors. Replace batteries in solar and wireless cameras. Review footage for unusual activity, such as people testing the door at night. Update the inventory of tools and equipment, and keep photos current.
