Our forensic video services include formal reports documenting the analysis, and our technicians may testify in trial as needed. Our forensic video analysis experts have previous courtroom experience and are familiar with how to present evidence accurately and thoroughly. Essentially, it is their responsibility to help the judge or jury understand the video evidence to the furthest extent.

When this illuminates, it tells drivers of drop-top cars that an obstruction or more serious fault could be preventing the roof from opening or closing.

This is an easy one. It means the car’s rear windscreen heater is on. Switch it off once you can see clearly out of the back.

To keep their cool, nearly all cars pump coolant fluid around their engines. If this warning light turns on, that coolant level could be dangerously low, or a blockage in the system could be causing the engine to overheat. Call out your breakdown provider or seek immediate assistance at the nearest garage.

Usually, the video evidence provided to our lab is digital. Most digital video recorders (DVRs) save recordings to a hard drive, however, some save recordings to removable media such as secure digital (SD) cards. Specialized tools are used to properly download the files to ensure they remain unaltered.

An amber airbag warning light usually signals that the front passenger side airbag has been switched off by the driver – such as when installing a rear-facing child seat in the front chair.

So much of a modern car is controlled by computer, and at the heart of such control systems is the engine management system. If the warning light comes on, the car will still function, but could possibly switch into what’s known as a ‘limp home’ mode with reduced performance. Have it checked out, pronto. It could indicate problems with the emissions control systems.

What is awarning signin driving

Most modern cars come with a system that keeps a watchful eye over the air pressure in the tyres. If it detects that one has fallen noticeably compared with the others, it will warn the driver. If your’e on the road, head for a petrol station and check the pressures and adjust accordingly. If your’e unsure on how to reset the tyre pressure monitor, the vehicle handbook will offer a step-by-step guide.

If the involvement of a person or object is in question during an investigation, our forensic video analysis experts use image comparison. This is the process of comparing digital images or digital captures from video recordings to determine the possibility of the object/person’s presence in the incident. This process is most accurate when the original video content is of high quality.

Trained video forensic experts use scientific processes to determine a video’s authenticity. It is not uncommon that we receive files that have been altered with malicious objectives or unintentionally by previous holders of the digital media. Our team can help detect and determine the nature of anomalies found in the recordings using a number of processes including:

Anti-lock brakes (ABS) are one of the greatest strides in making driving safer. They allow a driver to apply maximum braking and steer at the same time, such as when trying to avoid a pedestrian stepping out into the road. If the ABS warning light comes on, it means there is a malfunction with the system, and drivers should have it investigated.

To better understand the events captured by a recording, our digital video forensic scientists use a variety of processes to enhance video content. These processes are non-destructive and do not alter the original content at all. We provide both the enhanced content and original video in our final delivery. The enhanced deliverables can assist in court to prove a video’s relevance to the litigation.

The first thing to do if you see this symbol glowing on the dashboard is check the handbrake hasn’t been left on. Assuming it hasn’t, there is a fault with the brake system. That could relate to the worn condition of the brake pads or discs, a lack of fluid in the system or a problem with the anti-lock brakes (ABS) or stability control (ESP). Have it investigated by a garage as soon as possible.

Depending on the source, video evidence can come riddled with clarity issues, playback problems, or corrupted files. A video forensics investigation must be conducted in a lab equipped with specialized tools for file extraction and analysis. Our forensic video analysis experts come prepared with the proper equipment, software, and skills to address these potential problems and know how to conduct an investigation that follows the best industry practices. We ensure that video files maintain their integrity, and our forensic video services result in clear and concise deliverables for use in court, hearings, and mediations.

Video evidence can provide a real-time, eyewitness account of an incident in question. Footage that has been analyzed and enhanced by a digital video forensic expert can be used as evidence in litigation. For video evidence to remain permissible in court, it must be heavily scrutinized for validity and relevancy. Because of this, it is imperative that litigators enlist trained video forensic technicians to perform these analyses.

Plenty of posh cars come with air suspension systems. The appeal is that they allow drivers to tailor the driving experience, to an extent. This light can either indicate that you’ve left the air suspension in a raised setting, or there’s a glitch in the system.

Been driving in fog, and forgotten to turn off your car’s rear foglights? That’s what this symbol is there for, reminding drivers to switch off foglights.

Common methods for identification include facial image comparison, clothing comparison, gait analysis, vehicle comparison, and object comparison. The object or person in question is evaluated against a reference image, and a technician notes the similarities or differences.

With myriad electronic systems involved in the smooth running of the modern car, the ignition switch warning symbol could indicate all manner of maladies. So have the car checked over as soon as is practically possible.

Modern cars have dashboards packed with dials and an array of warning lights just waiting to switch on and confuse hapless drivers.

This generally tells drivers that the engine has lost oil pressure or is crying out for a top-up of oil. If you can’t remember the last time you checked the oil level, or had it changed at a garage, there’s a good chance it’s now at a dangerously low level – which could cause serious damage. So pull in to the nearest petrol station or garage, consult the vehicle handbook and check the engine’s oil level. The handbook will advise which type of oil is needed for a top-up.

Warningsigns examples

Usually, these warning lights aren’t a cause for concern, as they’ll go out once the engine’s running. But should they ever turn on during driving, you need to know what they mean, as some can indicate serious trouble.

The lights are coloured red, orange/amber or green, and work much like a traffic light system. Red is the equivalent of stop, and means the problem needs investigating immediately; orange or amber is an advisory signal, suggesting drivers will need to take action; and green says all is clear and serves as a helpful reminder.

Certain cars have sophisticated dampers in their suspension system, which can be set to be softer or firmer. If you see this warning sign, then the dampers will need checking.

It’s dangerous to have a faulty accelerator. What if it stops sending a signal to the engine to accelerate? Or worse, it sends the wrong signal and causes unintended acceleration? So if this warning light comes on, have it investigated immediately.

Most of us would struggle to turn a steering wheel if a car didn’t have what’s known as power assistance. This is a hydraulic or, increasingly, electric pump that helps turn the steering. So when the warning light for the system illuminates, take it seriously and have it checked out by a professional.

Usually, an amber steering lock symbol will indicate that the car’s steering lock needs to be released before the engine can be started. But if it remains red after starting the motor, it suggests there is a malfunction with the mechanism. In that case, don’t switch off the engine and head to a garage to have it inspected.

A Diesel Particulate Filter (DPF) is an essential bit of kit that captures many of the nasty toxic particles that come from burning diesel fuel. The warning light can signal that the car’s DPF needs to be cleaned out, a process which can involve taking the car on an extended high speed run. Or there may be a more serious problem, which can cause cars to fail the MOT’s emissions test.

As noted in the previous section, there are many types of digital recording devices, each with its own methods of exporting files. Our digital video forensic experts are familiar with all types of recording devices and take measures to collect the highest quality video files possible.  This allows the subsequent analyses to be performed more efficiently.

Warningsigns and symbols

The most likely cause of a red light with a battery symbol is that the car battery is no longer charging, or something is draining the charge when the car is parked and switched off. A flat battery is one of the most common causes for breakdown technicians being called out. So if the light comes on, your car will need further examination.

Your car’s Electronic Stability Programme (ESP, or sometimes ESC) is what keeps it securely planted on the road. It’s an important bit of kit, but sometimes drivers may turn it off. The warning symbol serves as a reminder. But if you haven’t switched it off and the light comes on, there’s a fault which requires further checks.

During the collection of evidence, our digital forensic experts follow the best industry practices outlined by the Scientific Working group on Digital Evidence (SWGDE). Throughout the entire video analysis, lab technicians are responsible for carefully documenting the chain of custody. The courts require this documentation to know exactly how video evidence was retrieved so that they may prove it was not submitted under false pretenses or inaccurately.

Some cars have Lane Keep Assist to help steer themselves back into the lane of a road if they detect that the vehicle is wandering too close to a white road marking or verge. This symbol indicates that the system is active. A red symbol means the system is faulty.

In cars that have a selectable four-wheel drive system, this light appears once the driver has chosen to switch from two to four-wheel drive operating mode, simply confirming their choice.

These days, most video media comes in a digital format, but TechFusion comes with decades of experience and can also work with video recordings from tapes, cassettes, and other analog sources. Just as we can authenticate digital videos, we can test and examine analog media to detect if it’s been recorded over or tampered with.

This red light may appear to be a picture of a passenger balancing a beachball on their lap, but it means that one of the airbags is malfunctioning. This is a serious matter, as it could fail to inflate in the event of an accident, or worse still, inflate without warning while you’re driving.

There are various types of cruise control these days, with passive versions that maintain a set speed, active systems which vary a car’s speed according to traffic conditions, and some that can even respond to changes in speed limits. The cruise control warning sign usually signifies that you’ve turned on the system.

TechFusion has served countless individuals, legal entities, and private corporations with forensic video analyses. Our results have aided in several high-profile trials, and our forensic specialists can provide expert witness accounts along with their investigations. From CCTV footage to mobile device recordings, our team is uniquely equipped to evaluate video evidence for use in legal proceedings, criminal investigations, and more.

An increasing number of cars now offer an electronically controlled child safety lock for the back doors. It saves drivers from fiddling around with catches, and once the symbol is illuminated, it’s simply confirming that the back doors can’t be opened from inside of the car.

Many cars no longer need a key in the traditional sense. Instead, they use a ‘smart key’ which is meant to be more convenient. If you unlocked your car and started it, then popped back into your house, accidentally leaving your smart key on the kitchen table when you did, this is your helpful reminder not to drive off without the ‘key’.

Every driver is likely to have seen this at least once. It means the car’s fuel tank is nearly empty and if you don’t put more fuel in, you’ll be grinding to a halt fairly soon - usually somewhere between 20 and 50 miles.

Headlamp or brake lamp bulbs fail from time to time. This helpful warning symbol will act as a challenge: do you try and replace the bulb yourself? Or pay a garage to put things right?

Once the footage has been collected and authenticated, our forensic video experts begin examination and analyses. After an initial viewing, we identify areas of interest for closer observation and possible enhancement. This includes sections of footage that relate to witness statements or identify suspects. It is necessary for the video analysis to be performed in a lab by experienced technicians with the proper tools to guarantee that the video evidence provides a reliable representation of the incident.

Automatic lights and windscreen wipers are becoming increasingly common on new cars. If this warning light appears, it’s telling you there’s a problem with one of them.

With years of experience and a track record of successfully uncovered evidence, TechFusion is widely regarded as an industry leader in digital video forensics. We collect, enhance, and examine video evidence for use in court, mediations, corporate investigations, and more.

With the use of surveillance cameras use becoming more and more common in both public and private spaces, video recordings are also becoming an increasingly common type of evidence presented in the courtroom. Furthermore, nearly everyone owns a mobile device with recording capabilities, so it is easier than ever to capture a crime scene on video. Our team has worked with hundreds of video files for litigation purposes.

When you see an orange symbol of a car leaving skid marks on the road, it can mean one of three things. If it flashes briefly, it’s simply telling the driver that the traction control system is doing its job and preventing wheelspin. If you have chosen to switch off the traction control, the light will remain on as a reminder that the system is inactive. But if it has turned on of its own accord, there is a problem with the traction control system which will need checking out.
