Stinger DoubleGuard Shock Sensor
A major security feature of the Viper 350 PLUS is its Stinger DoubleGuard shock sensor.
Dual-stage impact sensing allows the alarm to distinguish between different levels of physical disturbance.
A lighter disturbance can produce a warning response, while a more significant impact can trigger the full alarm.
That can help detect events such as:
- Someone striking a window
- Forced-entry attempts
- Body impacts
- Tampering
- Significant movement or disturbance
Sensitivity can be adjusted during installation to help reduce false alarms.
That’s important.
You want the alarm concerned when somebody hits the window.
You don’t necessarily need a six-tone emergency because someone put a shopping cart back with unusual enthusiasm.
Failsafe Starter Kill
The Viper 3105V includes Failsafe Starter Kill functionality.
When properly installed, starter interruption can prevent normal starter operation under applicable armed conditions.
That provides a second layer of protection beyond the siren.
The shock sensor helps detect tampering.
The siren attracts attention.
The starter interrupt makes simply starting the vehicle more difficult.
For a modified or enthusiast-owned vehicle, layering security features is generally much more useful than relying exclusively on noise. Our car alarm buyer’s guide explains how shock sensing, starter interruption, immobilization and other security layers work together.
Anti-Carjacking Security Function
The Viper 350 PLUS platform includes anti-carjacking functionality when properly configured.
This is designed to provide an additional security response in applicable situations rather than simply monitoring a parked vehicle.
Because anti-carjacking features can interact with vehicle operation and ignition behavior, configuration should be handled carefully by a professional installer.
The important distinction is that this feature does not mean the system contains GPS tracking or cellular remote shutdown.
It is an alarm-system security function—not a cloud-connected vehicle tracking service.
Panic Alarm
The Viper 3105V includes a panic function that allows the user to manually trigger an audible security response from the remote.
This can be useful for attracting attention or locating the vehicle in certain situations.
It’s simple technology, but simple technology has advantages.
No cellular connection required.
No login screen.
No forgotten password.
Press button. Car gets loud.
Revenger Six-Tone Siren
The 3105V uses Viper’s Revenger six-tone siren to provide an unmistakable audible response when the alarm is fully triggered.
The different siren tones help distinguish an active Viper security system from an ordinary factory horn.
The system can also integrate with parking-light output so an alarm event produces both audible and visual warnings.
Parking-Light Flash
When properly installed, the Viper 3105V can flash the vehicle’s parking lights during supported events such as:
- Arm
- Disarm
- Alarm trigger
- Panic activation
This provides useful visual confirmation and makes the vehicle easier to identify when the alarm is active.
Bright Blue Status LED
A bright-blue security LED provides visible system-status information while also acting as a deterrent.
Mounted where it can be seen from outside the vehicle, the LED lets someone looking through the window know that the car has an aftermarket security system.
That may not stop a determined professional thief by itself.
But security doesn’t always have to defeat someone after they attack the vehicle.
Convincing them to choose an easier target is also a win.
Auxiliary Outputs for Expansion
The 3105V provides auxiliary capability that gives a professional installer additional flexibility for compatible vehicle functions or accessories.
Depending on the application and additional hardware, auxiliary channels can potentially be used for functions such as:
- Trunk release
- Convenience accessories
- Additional vehicle-control functions
Exact capabilities depend on the vehicle and installation.
An auxiliary output is not a guarantee that every accessory can be connected directly to the alarm brain. Some functions require relays, interfaces or other supporting hardware.
Does the Viper 3105V Include Remote Start?
No.
The standard Viper 3105V is a vehicle-security and keyless-entry system, not a combined remote-start/security system.
This is important because some older product descriptions suggest that remote-start functionality can simply be “added” to the 350 PLUS.
Additional remote-start equipment and vehicle-specific installation would be required.
If remote engine start is one of your primary goals, buying a Viper system designed from the beginning for both security and remote start is usually the cleaner approach.
Consider products such as the:
- Viper 5305V
- Viper 5308V
- Viper 5808V
- Viper 5908V
Those systems integrate remote-start functionality directly into their respective platforms.
Does the Viper 3105V Include GPS Tracking?
No.
GPS tracking is not built into the Viper 3105V.
The 3105V is fundamentally a traditional RF vehicle-security system.
Do not confuse expandability with included functionality.
If GPS vehicle location and smartphone control are important, choose a compatible connected security platform and the appropriate GPS/cellular hardware.
Viper 3105V vs. 3100V
This is an important comparison for Pro Street shoppers because both products target affordable 1-way security.
Viper 3100V
- Entry-level 1-way security
- Shock sensing
- Starter interrupt
- Parking-light flash
- Keyless-entry capability
- Straightforward basic protection
Viper 3105V / 350 PLUS
- Enhanced 1-way security
- Stinger DoubleGuard shock sensing
- Failsafe Starter Kill
- Revenger six-tone siren
- Keyless-entry capability
- Panic functionality
- Anti-carjacking functionality
- Auxiliary expansion capability
- More feature-focused security platform
Choose the 3100V when cost and basic protection are the priority.
Choose the 3105V when you want a more feature-rich 1-way alarm without moving into 2-way security.
That gives the two products distinct places in the lineup rather than making them compete for exactly the same shopper.
Viper 3105V vs. 3305V Responder 350
The next major step is moving from 1-way to 2-way communication.
Viper 3105V
1-way security
The remote sends commands to the vehicle but does not provide remote confirmation.
Viper 3305V
2-way LCD security
The primary remote can receive supported status and command confirmation back from the vehicle.
Both are security-focused products rather than dedicated remote-start systems.
Choose the 3105V if you want straightforward security at a lower cost.
Choose the 3305V if remote feedback is worth the upgrade.
Viper 3105V vs. 5305V
The 5305V represents another significant step upward.
Viper 3105V
- 1-way security
- Keyless entry
- Shock sensing
- Starter kill
- No integrated remote start
Viper 5305V
- 2-way LCD security
- Keyless entry
- Shock sensing
- Starter kill
- Integrated remote engine start
- Up to 1/4-mile range
For security alone, the 3105V keeps the system simpler.
For security plus remote-start convenience, the 5305V is the more appropriate product.
Vehicle Compatibility
The Viper 3105V is designed for professional aftermarket installation across a wide range of vehicles, but compatibility should still be checked before purchase.
Installation requirements can depend on:
- Vehicle year
- Make
- Model
- Power-lock architecture
- Factory alarm
- Factory immobilizer
- Body-control electronics
- Door-trigger configuration
- Desired auxiliary functions
Some applications require additional relays or interface modules.
“Universal alarm” should never be interpreted as “plug this connector into every vehicle built since 1987.”
Automotive manufacturers have never made life that easy.
Professional Installation Recommended
Professional installation is strongly recommended for the Viper 3105V.
The installer may need to work with:
- Constant 12V power
- Ignition circuits
- Starter circuit
- Door triggers
- Hood and trunk triggers
- Power door locks
- Parking lights
- Siren
- Shock sensor
- Starter interrupt
- Auxiliary outputs
Incorrect starter-interrupt wiring can produce a vehicle that suddenly refuses to start.
When diagnosing problems like that, our engine cranks but won’t start guide can help distinguish security and immobilizer problems from fuel, ignition and mechanical faults.
