To help protect a car parked at home, layer devices with different jobs: a driveway camera and motion-activated light improve visibility and awareness; a steering-wheel lock adds a physical barrier; a signal-blocking pouch helps protect compatible keyless fobs from relay theft; and a garage alarm can alert you to entry. None guarantees that a car will not be stolen or damaged. Keep the vehicle locked, check that it actually locked, close the windows, and store keys away from doors and windows.

1. Outdoor driveway security camera or video doorbell

A camera aimed at the driveway can send motion alerts or record activity, giving you a way to notice what is happening and potentially retain evidence. Avon and Somerset Police recommends considering driveway cameras, CCTV, motion-activated lighting, or doorbells; South Australia Police describes Wi-Fi cameras with motion alerts and mobile viewing. See Avon and Somerset Police’s vehicle-theft advice and South Australia Police’s home security guidance.

A camera observes; it does not physically prevent someone from taking a car. Before choosing one, check:

  • Coverage: Can it see the vehicle, driveway entrance, and likely approach, including at night?
  • Alerts and recording: Does it provide motion notifications, recorded clips, and storage that suits your needs? Check whether storage requires a subscription.
  • Installation: Consider power, Wi-Fi reach, weather exposure, and maintenance.
  • Privacy: Aim it at your access points and avoid filming beyond your property where possible. Police Scotland advises avoiding footage of areas that are not yours or blurring them; check local requirements.

2. Motion-activated security light

A sensor-activated light makes the car and the approach more visible after dark. Hertfordshire Constabulary recommends PIR or LED security lighting, and Victoria Police advises considering a sensor light and CCTV for a car parked in a driveway. The police guidance presents lighting as a visibility and deterrence measure, not a guaranteed way to stop theft.

This measure is to prevent the dash cam from overheating.

Check the illuminated area, sensor range and angle, weather rating, mounting position, and power source. A poorly aimed sensor may trigger on passing traffic or movement on a neighbor’s property; adjust its position and sensitivity to reduce nuisance activations. See Hertfordshire Constabulary’s vehicle safety advice and Victoria Police’s advice on preventing theft from vehicles.

3. Steering-wheel lock

A steering-wheel lock is a visible physical obstacle that can make a vehicle harder to drive away, including if electronic security is bypassed. The Police Service of Northern Ireland recommends using a steering-wheel lock or car alarm as a keyless-theft countermeasure. Police.uk also advises considering additional physical security locks.

Choose a lock that fits your vehicle and look for credible security testing rather than relying on claims such as “unbreakable.” Police.uk notes that some devices tested to Sold Secure Diamond can resist a small hand-held angle grinder; that statement does not apply to every steering-wheel lock and is not a promise that a particular lock cannot be defeated. Check the product’s specific rating and compatibility. See PSNI’s keyless car theft advice and Police.uk’s vehicle-theft prevention guidance.

4. Signal-blocking pouch for compatible keyless fobs

Relay theft targets passive keyless systems: thieves can relay a smart key’s signal so the car behaves as if the key were nearby. A signal-blocking pouch, often called a Faraday pouch, is intended to block that signal when the fob is inside. PSNI recommends storing keys, including spare keys, in one when they are not in use. Keep keys away from the car, doors, and windows as well.

This device is relevant only to compatible electronic fobs. Confirm that the pouch blocks your own key’s signal rather than assuming every pouch works with every fob. A pouch also does not replace ordinary locking habits: manually check that the car locked, since electronic signals can be jammed. See PSNI’s guidance on preventing keyless car theft.

5. Garage door or motion alarm

If the car is kept in a garage, a door-contact or motion alarm can alert occupants to possible entry. Police.uk describes battery-operated alarms that respond to movement or door contact and recommends keeping garage and outbuilding doors locked. PSNI also recommends using and locking a garage and considering an alarm for the garage and gates.

  • Keyless car: Add a signal-blocking pouch for compatible primary and spare fobs, and verify manually that the car locked.
  • Car in a garage: Lock the garage and consider a contact or motion alarm; vehicle-side security and key protection still have separate roles.

When comparing products, assess camera field of view and night performance, light coverage and sensor behavior, vehicle and fob compatibility, power and connectivity, storage or battery costs, and any recognized security rating for a physical lock. The cited police guidance does not provide head-to-head device tests, quantified reductions in theft or damage, or verified current product prices, so it cannot establish which model offers the best performance or value.

What the police statistics do—and do not—show

Victoria Police says police intelligence indicates that more than 10,000 vehicles are stolen by thieves using electronic devices in Victoria each year. The page does not state the statistic’s reference year, so it should not be read as a confirmed 2026 count or used to infer a trend. It describes the scale of electronic-device theft reported by that source, not the effectiveness of any particular product. See Victoria Police’s motor vehicle theft page.
