There are two types of hard drives; surveillance and ordinary hard drives.
Surveillance hard drives are able to read and write large amounts of data within a short time and are designed to work 24 hours in a day and 7 days a week.
Normal hard drives on the other hand are designed to work for six days a week and only 8 hours in a day.
In order to know the difference between these two it is important to first of all know them individually.
What is a surveillance hard drive?
A surveillance hard drive is basically a hard drive which is built in such a way that it is able to process a lot of data from cameras with high definition accurately.
At the same time, it is able to maximize the lifespan of the drive and its consumption of power with reading or writing recording setups 24/7. Surveillance hard drives are generally not meant to be used in average or ordinary PCs, but they perform very well in high end security systems.
Surveillance hard drives are special in a way because of their ability to write very large amounts of data within a very short period of time. They are able to do this due to the special extra features that they possess which makes the work easier. For instance, they have command sets of ATA streaming that make it easier to perform the task.
The command sets of ATA are values that communicate to the HDD on how long it is going to take to write and read the data being streamed in. The HDD is then able to optimize the workload and read and write data in the shortest time possible. It is able to work smart rather than hard.
Also, surveillance hard drives have the ability to rate your workload to enable you know the amount of data you are going to run the drive in a year, hence prevent failure. At the same time, they are able to work through 24 hours in a day, thus maximizing their lifespan.
Can I use surveillance HDD in NAS?
Yes, surveillance hard disk drives can work with network attached storage (NAS) to yield very good results. In fact, they give long term services that run 24/7. However, the drives in most computers are not designed to work in this way.
What is advanced surveillance technology?
Advanced surveillance technology is simply surveillance that analyzes and provides high security. Examples include Verint system, Bynet, Megal security, Agent Vi, Camero, Seaye Underwater, Adaptive Imaging, Mate Intelligent Video and Laser Microphone.
Looking at them one by one:
- Verint System
This provides hardware and software to intelligent markets and is widely used all over the world. The most popular products from Verint System include software for speech analysis and surveillance cameras that are internet controlled. Recently, they have also launched a forensic tool which provides a view of 360 degrees where detailed investigation is required.
Bynet is also well known for the services it provides in video surveillance, especially in recording and monitoring systems. Its main feature is a system of communication which can transmit information through a secure broadband connection. The products can also record a vehicle’s interior when it is several hundred meters away.
- Magal Security
Magal Security is known especially for CCTV development, intrusion detection system and IP surveillance. Their products have been used in terrorism prevention among many other sensitive and vulnerable activities. Through their products, they have kept many people safe.
- Agent Vi
Agent Vi mostly manufacture products for business intelligence and military and government surveillance. Their products are also used in monitoring traffic and in highway security. They feature forensic research and real time detection. Their products can analyze several hundred cameras at the same time with results being a huge percentage true.
Camero’s products are mainly security cameras. Their most interesting feature is that they can see right through walls. The cameras can generate 3D images of objects which are blocked by solid barriers.
- Seaeye Underwater
These produce the most advanced technology for use underwater. Unlike most standard surveillance cameras, Seaeye underwater cameras are able to provide clear image underwater and at the same time give high data transmission. Regular surveillance cameras give low resolution images and only cover a short distance. Seaeye surveillance cameras are therefore able to prevent a lot of terrorist attacks that are done through the sea.
- Adaptive imaging
Adaptive Imaging Technologies is a company that has developed a camera with 1000 megapixels and covers a large area. The camera is called a panoramic telescope and has the ability to be zoomed at ultra-high resolutions for security purposes. Their focus is on the transport system, urban areas and borders of countries.
- Mate Intelligent Video
Mate Intelligent Video has a system that is able to convert a regular camera into an intelligent and smart system. Their products can also count people and cars as well as track objects in a large filed. Also, they can transfer bi-directional information so as to secure a site that is remote. Their products are mainly used in remote areas to detect any activities that are deemed suspicious.
- Laser Microphone
Laser Microphone’s technology is mainly used in spying. The microphone has the ability to capture sound vibrations a long distance off through the use of a laser beam. The beam spreads into the room and, falling on the waves of sound, is reflected to a receiver which in turn converts the sound wave into a sound signal. This technology was used in the famous Osama bin Laden mission that saw him dead.
- Pre-Crime Cameras
This is a futuristic technology. These surveillance cameras are able to monitor facial expressions and pulse rates by using sensors of thermal imaging. Such technology is able to alert security personnel before a criminal activity is done. These cameras also have their own memory, enabling them to calculate and determine criminal activity.
- Facial Monitor Surveillance
This is yet another futuristic technology. It enables the cameras to pick out a specific required face from a large crowd. It is for use in crowded places. It is also to be used in laptops to enable them pick out minute facial expressions. This enables an employer to monitor the employees’ fatigue and also to do market research.
- RFID Microchip
RFID microchips are integrated circuit devices that are implanted in a human being’s body. Such a microchip contains a unique number that gives information about the specific person in which it is implanted. The microchip also stores the person’s contact information, medications and medical history. It was first done successfully in 1998 but is still at the developmental stage due to the lack of worldwide acceptance because of the health risks it poses.
What are the capabilities of advanced surveillance technologies?
As mentioned above, advanced surveillance technologies have varied capabilities that are actually very interesting. For instance, the Seaeye underwater technology is able to produce very high definition images in water and for a long distance.
Others are able to see through solid objects to create an image in the camera, others can transmit real-time information through broadband connection while others can analyze hundreds of cameras at a time without giving faulty results. Also, others like Adaptive Imaging can cover a wide area as they have 1000 megapixels ability.
There are also those that are able to detect specific faces in a large crowd and even count and track people and cars in large fields. Others are known for detecting and tracking sound and are used in combating terrorism. Last but not least, there are those that have the ability to detect minute facial expressions and hence aid employers to track their employees’ fatigue.
How is ICT used in surveillance?
Information Communication Technology (ICT) has been in the center stage of surveillance. The two go hand in hand. It is almost unthinkable to consider surveillance working without the aid of ICT. ICT has enhanced surveillance systems to work in a way that was previously not possible.
The two work together to come up with ICT surveillance systems, which are systems enabling the collection and monitoring of data which in turn is stored or transferred through information communication technology mediums such as computers and mobile phones.
The different kinds surveillance systems that use ICT include but are not limited to:
- IMSI Catchers; which are used to identify and track mobile phones.
- Intrusion software; which is inserted in mobile phones and computers without being detected in order to monitor and control the ICTs.
- Monitoring centers; which are used by security personnel to collect and analyze communication data given by different surveillance systems.
- Probes; which collect data that is passing through various communication networks.
- Digital forensics; which enable security personnel to retrieve data which is stored in various ICT mediums such as mobile phones and computers.
Going by the examples, it is evident that ICT is applied centrally in surveillance systems.
