 Advantages and Disadvantages of CCTV

Setting up a closed-circuit television (CCTV) system is one way to help increase security around your home or business. Like most things, it comes with its own list of pros and cons. Learn more about the advantages and disadvantages of CCTV then decide for yourself if it’s right for your security needs.

Technology is a double-edged sword. While innovation and upgrades can have several benefits for us, they can also be used to cause trouble. The majority of us reap its advantages, but a few with vested interests continue to abuse it and make the lives for the rest of us miserable. The security camera is one of the wonders of modern technology, which is used at homes as well as in offices. It has gained immense popularity as an effective security measure, thanks to the plethora of benefits it offers. But just like other inventions, security cameras have a few drawbacks as well. The advantages, however, outnumber the disadvantages, and this revolutionary equipment continues to be popular with those serious about keeping their loved ones and assets safe and secure.

What is CCTV

CCTV (closed-circuit television) is a monitoring system comprised of recording devices that are not publicly distributed. Surveillance cameras are directly connected to private monitors and recording devices for immediate viewing and storage. The primary use is for home or office security.

Advantages of CCTV

Security is an important factor in both the home and workplace. Anything that increases security measures has obvious advantages. Some of these pros include:

• Increased safety and security
• 24/7 surveillance
• Crime deterrent with visible cameras
• Evidence to any criminal activities caught on tape
• Set up remote access
• Discounted insurance

Whether you set up a CCTV to help protect your family or employees, it’s well worth the investment. But there are still some issues to be careful about.

Disadvantages of CCTV

One of the biggest disadvantages of CCTV use deals with privacy, especially when used in the workplace. While it may be there to help keep employees and customers safe, they may object to being filmed under constant surveillance. Employees may also feel like they aren’t trusted, which is not good for business. You need to disclose that the area is under surveillance, or else there could be legal action taken against your company. Be aware of the laws in your state before setting up cameras in public spaces. Another disadvantage of CCTV is the cost. Cameras, monitors, recording devices, and other equipment cost start to add up. Then it comes time to update the technology, which adds to the bottom line.

CCTV, or closed circuit television, is the most commonly used security system for homes, stores, banks and businesses. A CCTV system is made up of single or multiple cameras, a recording device and a monitor. Systems can be wired or wireless. While CCTV has many advantages, there are disadvantages in both types of system.

Limitations

A major disadvantage for CCTV cameras is that they can only monitor a limited area. Criminals can vandalize the cameras in various ways, such as sticking gum or spraying something on the lens. They may even be able to change the angle of the camera. Criticism from the general public is usually about the lack of privacy and high cost to install for personal use.

Wireless Systems

Wireless systems need a specified frequency for the camera to send signals to the receiving and recording station. Other electric motored products, such as air conditioning, fluorescent lighting and cordless telephones can cause interruptions in the frequencies, affecting the picture quality. Wireless systems are subject to distortion in image quality, and need experts in wireless technology to identify and repair system breakdowns. Some systems may not be completely wireless, as they require an electric power cable. Wired CCTV systems have the disadvantage of being fixed to a particular area, meaning the camera can't simply change location. The installation and cabling of these cameras is a difficult task that demands the assistance of professionals.

Hacking

The value of CCTV information has increased, resulting in a higher risk from hackers. Hacking CCTV footage has led to privacy issues, such as images captured by CCTV of naked women distributed across the Internet. It is not possible to completely protect public security systems from hackers. As the system connects to a network, hackers can hack into the system virtually from outside locations.

Wireless Camera Hacks

Hacking can modify the functions of a wireless camera to display computer-screen content on an external viewing device. Such modifications, while simple, will void the manufacturer's warranty and often require additional equipment, such as a wireless receiver and patch cables. Some camera-related hacks, like breaking into a transit system’s closed-circuit TV network or spying on a neighbor’s activity, aren't necessarily legal or advisable.

Wireless Cameras

Wireless cameras are essentially radio frequency transmitters that capture video data with a lens and relay it to a receiver. Televisions, dedicated security monitors and computer displays, which serve as input devices for the data, are often backed up with a VCR or digital video recorder, or DVR. You can hack most wireless cameras with software or minor physical modifications.

Types of Hacks

Typical wireless security camera hacks include physically altering your camera to display onscreen computer content on your TV, and adding software that allows your camera to act as a security device that sends you an email when it detects activity. Some other hacks potentially violate privacy laws, such as hacking into an unsecured wireless network and using software to remotely control the attributes of someone else’s wireless camera, or hacking a local area network near your computer’s location and acquiring a third-party’s captured data.

Uses

Non-malicious hacks expand on your camera’s capabilities and increase its functionality. For example, hacking your wireless webcam to function as a motion-activated CCTV camera allows you to covertly record and monitor sensitive areas of your home or business for protection against break-ins, theft and other illegal activity.

Minor modifications to your wireless camera’s printed circuit board allow you to use the camera to transfer onscreen computer content without use of a high-definition multimedia interface or video graphics array cables. Older TVs often lack these inputs and rely on RCA patch cables for audio and visual connections, which limit their use as an external viewing device. These hacks are best suited for media applications, such as viewing video games or streaming movies on a bigger screen.

Hacking Methods

Using your wireless camera as a means of viewing computer content on a TV involves disassembling the camera and removing its printed circuit board. You must reflow, or melt, the wire leads from the lens that connect to the circuit board, as this hack only uses the camera’s radio frequency transmitting function. After soldering a cable compatible with your TV’s input ports to a wireless receiver and adjusting your computer settings to send the display to the PCB, your content will display on the TV screen. Hacking your wireless camera to serve as a CCTV security camera doesn’t requires physical modifications, but instead relies on software that allows your camera to begin recording when it detects activity. Programs such as Yawcam, Active WebCam and Ugolog employ your existing wireless camera hardware to distribute captured data over an LAN or, if using a wireless IP camera, over the Internet, so you can log in remotely and view its activity. Other software functions include a “growl” function, an informal term describing the option to send you an email or text message when activity on-camera is detected.
