Best Security System For Car: Compare Alarms and Trackers

#1 · Best Overall

1. Viper 5706V

• Compatible Devices: Security Systems, Remote Start Systems…
• Warranty Description: 1-Year Manufacturer Warranty

Best for: Long-range two-way remote start.

Why it ranks #1: Combines two-way security and remote start with a five-button LCD transmitter, door and trunk triggers, and a stated one-mile range.

A stated one-mile range gives the Viper 5706V remote start and security commands reach beyond close parking-lot use. Its five-button LCD transmitter displays priority icons and text, so owners can monitor the vehicle and issue commands through a screen rather than relying only on button presses.

The two-way security system combines door and trunk triggers with remote starting, covering both intrusion alerts and convenience commands. Its LCD transmitter uses priority icons and a text display to present vehicle information, while the five-button layout separates common controls. The listed one-mile range supports operation from farther away than a short-range remote. Compatibility includes security, remote-start, keyless-entry, and trunk-pop systems, with SmartStart also listed as compatible.

Skip it if you need the listed maximum range to reach farther; Compustar CS9920-AS specifies up to three miles.

This Viper suits drivers who want remote starting, two-way monitoring, and a readable LCD remote for a vehicle within its stated one-mile range. Consider the range boundary before choosing it for especially distant parking.

#2 · Longest Listed Range

2. Compustar CS9920-AS

• Compatible Devices: Vehicles
• Warranty Description: 1 Year Warranty

Best for: Extended-range remote start.

Why it ranks #2: Offers up to three miles of range and includes a shock sensor, siren, and LED with two-way LCD and LED remotes.

Up to three miles of stated range is the defining reach of the Compustar CS9920-AS, letting its T11 two-way LCD remote lock doors, start the engine, and check vehicle status from a distance. A second G17 two-way LED remote adds another transmitter option in the same security and remote-start kit.

The T11 LCD remote combines two-way communication with commands for locking doors, starting the engine, and checking status, making the display useful for both convenience and monitoring. The G17 LED remote supplies a second two-way transmitter option. The kit also includes a CM900-AS control module, shock sensor, siren, and LED, linking remote operation with listed security components. Its stated maximum range is up to three miles, so actual selection should account for that stated boundary.

Skip it if you want a system with a stated one-mile range and Viper's LCD priority icons; the Viper 5706V specifies both.

Choose the CS9920-AS if long-distance remote starting, two-way status checks, and two included remote types suit your routine. Its stated range reaches up to three miles, while the included shock sensor, siren, and LED address security hardware.

#3 · Best Two-Way LCD Controls

3. Viper Responder 350 3308V

• Compatible Devices: cars

Best for: LCD confirmation with SmartStart option.

Why it ranks #3: Pairs a two-way LCD command-confirming transmitter with a one-way remote, impact sensor, six-tone siren, and up to 1/4-mile range.

A two-way LCD command-confirming transmitter is paired with a separate one-way four-button remote in the Viper Responder 350, giving owners two listed control styles. Its impact sensor alerts when the vehicle is struck, and the six-tone siren helps distinguish the alarm from others.

The LCD transmitter confirms commands, while the one-way four-button remote provides an alternate control option. An impact sensor supplies the stated trigger for alerts, and the six-tone siren differentiates the alarm sound. Door locking and unlocking occur while arming and disarming if installed, so that function depends on installation. Viper SmartStart Pro compatibility enables remote starting when paired with the separately sold system; the supplied description states a range of up to one-quarter mile.

Skip it if you want remote start included in the system; the Viper 5706V lists remote start as part of its system.

Choose this Responder 350 for LCD command confirmation, an impact sensor, and a distinctive six-tone siren. It suits drivers comfortable with door-lock operation depending on installation and with SmartStart Pro required separately for remote starting.

4. Viper 5305V

• Compatible Devices: Viper SmartStart
• Warranty Description: 1-Year Manufacturer Warranty

Best for: LCD remote-start system shoppers.

Why it ranks #4: This vehicle alarm listing identifies keyless entry and remote start, making it a relevant choice, though detailed range and component information is sparse.

A two-way LCD remote pairs with keyless entry and remote start in the Viper 5305V, giving this system a combination of vehicle access and remote-control functions. Its title identifies the product as a vehicle car alarm system, while Viper's supplied facts also identify replacement and additional remotes as available options.

The two-way LCD designation points to a remote interface with display-based operation, while keyless entry handles access and remote start adds a convenience function. The listed compatible device is Viper SmartStart, which is relevant to buyers considering that ecosystem. Viper also states that replacement or additional remotes are available in one- or two-way options, with button counts from one to five and LED or LCD features. The supplied product facts give the 5305V designation but few system-level specifications.

Skip it if you require a stated range for choosing a remote; the Viper 5706V specifies up to one mile.

The 5305V may suit shoppers seeking a Viper system combining LCD remote operation, keyless entry, and remote start. Its supplied details are sparse on system specifications, so favor a product with a stated range if distance is central.

#5 · Best One-Way Alarm Features

5. Viper 350 PLUS 3105V

• Compatible Devices: cars
• Warranty Description: 1 Year

Best for: Starter-kill entry alarm.

Why it ranks #5: Includes keyless entry, a FailSafe starter kill, anti-carjacking and panic alarm features, plus a six-tone siren and blue status LED.

A FailSafe starter kill anchors the Viper 350 PLUS 3105V, adding a starting deterrent to its three-channel, one-way security system and keyless entry. Its four-button remotes operate the system, while a six-tone soft-chirp siren, parking-light response, and bright blue status LED provide audible and visible signals.

The starter-kill feature works alongside the alarm functions to address both unauthorized starting and detected disturbance. Three-channel one-way security and keyless entry combine routine access with alarm operation, controlled using four-button remotes. The six-tone soft-chirp siren and parking-light response offer distinct audible and visible alerts, while the blue LED communicates system status and warns would-be thieves. Remote starter and GPS tracking are described as additional options, not included functions in the listed core system.

Skip it if you want included remote starting and two-way LCD control; the Viper 5706V lists both in its system.

This Viper fits drivers seeking keyless entry, starter kill, and clear siren and light responses in a one-way alarm. Remote start and GPS tracking are described as additional options, so choose it for the listed core security functions.

#6

6. Keep Car Alarm

• Compatible Devices: iPhone, Android
• Warranty Description: 1 year manufacturer

Best for: Automatic phone-and-keyfob arming.

Why it ranks #6: Adds GPS, motion sensing, 1080p pictures and video, a 120dB sound, and automatic arming based on keyfob or phone presence.

Automatic arming and disarming based on the presence of a keyfob or phone lets the Keep Car Alarm operate without a button press for those actions. Its listed security package adds GPS, motion sensing, 1080p pictures and video, a 120dB sound, and flashing bright LEDs for a layered deterrent.

Presence-based arming and disarming reduces the need to remember a separate button action when approaching or leaving the vehicle. GPS and PIR/radar motion sensing are named alongside 1080p pictures and video, giving the system both location and sensing components. A 120dB sound and flashing bright LEDs provide the listed audible and visible deterrents. The product is compatible with iPhone and Android, while 4G/LTE appears in the title; those communication details matter to buyers considering its smart-security workflow.

Skip it if you prefer an OBD-II tracker with map updates and no stated camera components; Ring Sensors lists that setup.

Consider Keep if automatic presence-based arming, GPS, motion sensing, and camera capture suit your security priorities. Its phone-and-keyfob workflow and listed sound and light deterrents make it a different fit from a basic remote-operated alarm.

7. CARLOCK Ultimate Security Bundle 2.0

• Compatible Devices: Cars, Trucks, Motorcycles

Best for: Multi-vehicle tracking bundle.

Why it ranks #7: Combines a real-time tracker and alarm with a Bluetooth vibration sensor and TAG accessory; listed compatibility includes cars, trucks, and motorcycles.

A bundled real-time tracker and alarm lead the CARLOCK Ultimate Security Bundle 2.0, adding a tracking-focused approach to vehicle protection. Its package also names a Bluetooth vibration sensor and TAG accessory, while listed device compatibility spans cars, trucks, and motorcycles for owners managing different vehicle types.

The bundle pairs its real-time tracker with an alarm, so tracking and alerting are presented together rather than as separate product categories. A Bluetooth vibration sensor adds another named component to the package, and the TAG accessory is included as part of the bundle. CARLOCK describes its device as specialized for anti-theft, and compatibility covers cars, trucks, and motorcycles. The supplied information does not detail installation steps or specific alert workflows, so buyers should weigh the stated bundle contents and vehicle coverage.

Skip it if you want a clearly specified phone-app alert workflow; Ring Sensors lists app notifications and map tracking.

This bundle fits owners seeking a tracker, alarm, vibration sensor, and TAG accessory in one package, including those with cars, trucks, or motorcycles. Choose it for the stated components, bearing in mind the supplied details do not explain setup.

#8

8. Viper Responder 350 3305V

• Compatible Devices: Cars, Trucks
• Warranty Description: 1-Year Manufacturer Warranty

Best for: Code-hopping two-way protection.

Why it ranks #8: Provides two-way security, a stated range of up to 1/4 mile, clone-safe code-hopping, and two auxiliary outputs.

Clone-Safe Code-Hopping is the Viper Responder 350's defining security feature, pairing with two-way operation for drivers who want a remote system with a stated range of up to one-quarter mile. A bright blue LED status indicator adds a visible signal at the vehicle, while two auxiliary outputs provide additional control connections.

The up-to-one-quarter-mile range sets the operating boundary for remote use, while two-way security provides a remote interaction beyond a one-way alarm. Clone-Safe Code-Hopping is specified as a security feature, and the bright blue LED status indicator gives a visible cue at the vehicle. Two auxiliary outputs offer connections for additional functions. The listing identifies compatibility with cars and trucks, making this a fit for those vehicle types who prioritize the stated control features over extended range.

Skip it if you need a longer stated range for remote commands; the Viper 5706V specifies up to one mile.

This Directed-branded Viper suits car and truck owners seeking two-way security, code-hopping, and auxiliary outputs. Its one-quarter-mile stated range is the key boundary, so match it to your parking distance and remote-control needs.

#9

9. Viper 3100V

• Compatible Devices: Smartphone

Best for: Basic monitored entry protection.

Why it ranks #9: Covers doors, bonnet, boot, and two-stage shock detection, with engine immobilization and keyless entry, but listed details omit remote range.

Two-stage shock sensing pairs with door, bonnet, and boot protection, giving the Viper 3100V several ways to detect disturbance. It also immobilizes the engine and flashes the parking lights when armed, disarmed, or triggered, combining intrusion deterrence with visible status cues for everyday parked-car security.

The two-stage shock sensor distinguishes impact levels, while door, bonnet, and boot protection covers several access points. Engine immobilization adds a separate barrier to starting the vehicle, and parking-light flashes communicate arming, disarming, and triggered status. Keyless entry handles routine access alongside security functions. The system is identified as one-way, so it suits drivers who want basic controls and alerts at the vehicle rather than two-way remote confirmation. Smartphone compatibility is listed, but no app functions are specified.

Skip it if you need remote confirmation or remote start; the Viper 5706V adds two-way control and remote starting.

Choose this Viper for a straightforward alarm with impact sensing, access-point protection, and keyless entry. It fits drivers who value immobilization and visible parking-light signals, but not shoppers seeking two-way remote feedback or a listed remote-start function.

#10

10. Ring Car Tracker and Alarm

Best for: Tool-free app-based vehicle tracking.

Why it ranks #10: Focuses on location tracking and disturbance alerts through an OBD-II connection, rather than the remote-start and alarm controls offered by higher-ranked systems.

An OBD-II connection powers the Ring Sensors car tracker, enabling vehicle location tracking without tools, wiring, or a complicated setup. The Ring app shows the car on a map with periodic updates and sends alerts for impacts, door openings, and other disturbances, all with no monthly subscription listed.

The OBD-II connection supplies the stated vehicle interface and makes installation a plug-in process, avoiding wiring work. Once set up, the Ring app presents location on a map with periodic updates, while disturbance alerts cover impacts and door openings. The listing says it works with most vehicles and specifies no monthly subscription or hidden fees. Because location updates are periodic, this is a tracking-and-alert workflow rather than a promise of continuous map refreshes.

Skip it if you need a security system with an included siren and remote transmitter; the Viper 350 PLUS lists both.

Pick Ring if app-based location tracking, disturbance notifications, and tool-free OBD-II setup match your priorities. Its updates are periodic, and the stated installation relies on an OBD-II port, so check that workflow against your vehicle needs.
