No crime-fighting weapon is foolproof, and criminals may find ways to avoid a camera. However, a well-placed security camera can send a clear message to criminals that your property is protected, deterring them from choosing your business as a target.
Many businesses see significant reductions in non-violent crime after installing a security camera system. In addition, a system can alert employees of unauthorized behavior and help prevent employee fraud (estimated to cost companies 5% of their annual revenue).
Regarding theft of inventory or equipment, security cameras make it easy to detect suspicious activity. In some cases, an alarm from a motion detector can even be sent directly to police officers so they can dispatch an officer to the scene before any more damage or theft occurs.
Security cameras can also provide a clearer picture of moving objects, allowing you to zoom or pan the camera digitally. This helps identify individuals and can even help you distinguish between a person and a car, for example. This kind of clarity can be especially useful in public spaces, where security cameras help to deter crime by providing a clear first line of defense and a psychological barrier that says, “Back off, punk,” to anyone up to no good.
Some security camera systems come with a built-in microphone to enable two-way audio. However, be aware that recording audio may infringe on people’s right to privacy and is illegal in some states. For this reason, many home security cameras don’t record audio.
Most modern security cameras use a Wi-Fi network to transmit pictures and video data. This is similar to the way that many smart devices (like your phone, tablet or computer) connect to the internet. Many cameras will connect to your Wi-Fi, allowing you to access them remotely through an app on a smartphone or other device. Some cameras for the home market also connect to your network using an Ethernet cable, which can offer better reliability.
Some security cameras will transmit and store footage in the cloud, while others use a hard drive or Solid-State Drive to save information locally. The type of storage used will affect the size of the recording capacity. If you’re considering a cloud or hybrid solution, be sure to ask your provider about the available storage capacity.
Capturing Evidence
While a security camera can help deter crime, it’s also an important tool for capturing evidence to protect you and your business from liability issues. Potential liabilities can be caused by accidents, theft, vandalism or even a simple oversight that could lead to loss of productivity or customers.
A security camera can help you identify the cause of these events and take corrective action. If you can prove that a particular incident was caused by a specific act, then you may be able to recover damages from the responsible party. To be admissible in court, surveillance video must meet several criteria, including authentication and authenticity. Authentication requires proof that the video came from a reliable source and that it is accurate. Authenticity involves demonstrating that the video has not been altered in any way that would significantly affect its meaning or interpretation.
To ensure that your security camera footage is admissible in court, make sure you follow these tips:
Changing your camera’s default login credentials will prevent anyone else from accessing your surveillance data. If you have a wired system, check that your cameras are connected to private Wi-Fi so that only those logged in to your network can view the feeds. You should also verify that your camera can record audio. If it does not, consider investing in a new camera with the ability to capture sound or invest in a microphone adapter.
Forensic experts often encounter problems when attempting to use surveillance videos as evidence. For example, older systems with lower frame rates cannot be used as they provide too few images per second to accurately identify a subject. The popularity of pan, tilt and zoom (PTZ) cameras can also be problematic from a forensic perspective. The fact that different cameras can be moved to different PTZ positions can create a jumbled image of a suspect that forensic experts cannot easily sort out and use.
It is essential to understand the laws in your jurisdiction regarding security camera use and installation. In the United States, security cameras can be installed on residential and commercial property as long as they do not violate a person’s “reasonable expectation of privacy.” This means that a camera must not be placed in a place where people shower, change, use the restroom or sleep without their consent.
Managing Risk
The use of security cameras in businesses can help reduce the risk of liability. For example, a video surveillance system can capture a workplace accident or a theft and provide evidence to help defend the business against a claim. Security cameras can also be used to monitor employee activity and ensure compliance with company policies. This can help reduce the number of claims made against a business and increase efficiency by eliminating the need to conduct time-consuming internal audits.
However, there are still some risks with using security cameras in the workplace. The most obvious concern is that security cameras can be hacked and used as an entry point into the corporate network. This vulnerability can be exploited for many purposes, including malware attacks and phishing, as well as to steal data. In addition, the camera can be used to spy on employees or customers.
Regardless of whether they are being used in a home or business, all Internet-connected devices have a risk of hacking. This includes DVR/NVR/VMS systems and cameras, smart locks and lights, and other connected devices. Most of these devices are designed to be managed over the Internet and use a Web-based graphical user interface (GUI). Many of these systems are on the same network as other IT systems, exposing them to the same threats that any computer or smartphone faces.
All of these devices have operating systems, and just like any other operating system, they can be prone to vulnerabilities. It is important for IT teams to change all passwords on a regular schedule and enforce strict password quality standards, as well as keep the software up to date. Lastly, if you are considering purchasing a camera that offers remote access, it is imperative to make sure that the connection is encrypted, as this protects against eavesdropping and privacy breaches.
Managing these risks can be difficult, as manufacturers are always pushing to release products and build a market share quickly. This means that some devices are released before they have been fully tested for security issues, making them vulnerable from the start. For example, the TP-LINK TAPO C200 camera was found to have a serious issue that allowed attackers to take control of the device remotely, even after an upgrade. This included gaining full API access, moving the motor of the camera, erasing the contents of the external storage and creating new user accounts.
Efficient Operations
Security systems have gone beyond ensuring safety and deterring misconduct to assist in operational efficiency and decision-making. Today, smart security solutions integrated with business intelligence components can deliver valuable data to help businesses maximize revenue and growth.
A key advantage of modern surveillance technology is that it offers greater scalability and cost-efficiency than older CCTV (closed circuit television) systems. Instead of requiring dedicated servers, a network video recorder (NVR) or digital video recorder (DVR) is used to store footage for playback and analysis. An NVR or DVR can be connected to a camera using wired Ethernet, power over Ethernet (PoE), or Wi-Fi. It can also be remotely accessed over the internet.
For a smaller deployment, some cameras may be designed to only record video or take pictures when motion is detected. This reduces storage requirements and bandwidth usage, making it a popular choice for homes and small businesses.
With the advent of AI and edge-based video analytics, modern surveillance cameras can detect specific people or objects in their field of view. This can greatly speed up incident response times and improve the efficiency of operators. Combined with facial recognition, vehicle matching and other analytics software, these technologies can provide the tools needed to prevent incidents before they happen and to quickly identify perpetrators.
Video recording can be saved on a hard disk drive or Solid-State Drive (SSD) for local storage, which reduces the risk of theft or loss of critical evidence. Some advanced solutions can be configured to encrypt data while at rest or in transit, which keeps hackers from lifting sensitive company information or disabling cameras.
Many businesses are required to retain security footage for a certain period of time, depending on industry regulations and local laws. To minimize storage costs and ensure compliance, some security camera systems are able to automatically save video to cloud-based storage or an onboard SSD or HDD.
With built-in automation features, security cameras can be programmed to automatically perform equipment health checks, scene-checks and other critical actions at set intervals. This can help reduce the need for manual intervention and free up resources to focus on critical incidents.
