From bus stops to school premises and even school buses, security cameras have become a part of the security measures taken by the school authorities to ensure the safety of the students that thousands of parents entrust them with. Now that activities of violence and crime are not restricted to any particular kind of surroundings alone, school authorities and parents are equally at peace when such security measures are taken.

Most school buses uses multi-channel DVRs that record various views from different security cameras installed inside and outside the bus entrances. These cameras are generally equipped with audio and GPS functions as well. However, recording audio is not usually permitted as it is illegal in most countries. There are instances where school authorities have been sued for recording audio, as it is a breach of privacy and can be mistaken as a wrong disciplinary measure taken by the school.

Also the security cameras in school buses are not meant to be kept covert and the students are to be aware that the cameras are in action. However, even though the cameras are not used as a measure to induce discipline, many school authorities claim the awareness about the security cameras has helped in bringing about discipline without making the students self-conscious or uncomfortable. If implemented in the right way, security cameras in school buses can be a very successful security measure for schools.

We at CCTV4U have a wide range of security cameras and equipment fit for all kinds of surveillance.

Ignoring the blaring red light on the traffic post is found to be the major causes of crashes and accidental killings during the rush hour traffic. The red light security cameras have come as a very useful tool for thwarting the tendency of poor drivers to ignore the red sign.

The red light security cameras installed at major intersections has helped in bringing down red light running to a large extent. These security cameras automatically take the photographs of vehicles that drive past the intersection after the light turns red. Sensors embedded in the cross walks are activated when the vehicles violate the red light, and cameras mounted on the poles capture the picture of the vehicle along with the date, time and its speed.  Citations are then mailed to the driver to pay a fine or sign an affidavit indicating that they were not driving at that time.

This system, which has been extensively tried out in many parts of the world, has yielded very good results and has helped in bringing down the rate of red light runners considerably. However, there are some arguments against the system as well, as some people argue that this is leading to rear-end collisions as many drivers stop abruptly at the signals. It is argued that some authorities are using this as a money-making device.

If implemented correctly, this security system can go a long way to increase the security on the roads. To know more, our friendly team at CCTV4U are experts at dealing with queries about CCTV equipment.

With the seeming trend of increasing numbers of incidents of vandalism to school property, security systems in schools have arguably become imperative for student and school safety. However, owing to the initial cost involved and concerns regarding the intrusion into privacy, many schools are refraining from adopting the security surveillance option.

It would be beneficial for the school authorities to weigh the reasons as to how the installation of a security system could benefit them to reach the right decision. The school authorities can go through the problems and analyse what security threats the new CCTV cameras would address, and how those cameras would help in addressing those issues. Consideration also needs to be made on how the security system will be maintained and personnel allotted if the system is installed.

Once these issues are considered, it would be easier for the authorities to decide if the benefits would outweigh the costs. Moreover, as privacy issues are also concerned it should be considered if installing the cameras in the entrances, common areas and parking lots alone would serve the purposes they are aiming at.

Even though the initial costs are slightly high, many schools who have adopted CCTV surveillance claim that the CCTV systems are quite cost-effective in the long run and have been extremely beneficial in bringing down the damage to school property as well.

At CCTV 4U we ensure that the best CCTV equipment and services are made available that make the investment worth its cost, for security is one thing that no compromises ought to be made upon.

As with every technology, video analytics too comes with its constraints. When CCTV systems with video analytics clearly have several advantages over the conventional systems, there are a few factors which determine the performance of the system. Though it is sometimes said that the chances of false alarm is quite high when using video analytics, their chances of occurrence can be brought down to quite a considerable extent if other governing factors are taken care of.

Processing Rate: Higher processing rate is essential as the system would require a higher frame rate and resolution to detect small objects moving quickly.

Frame rate: Most systems require a frame rate of at least 5-8 Frames per Second (FPS). Tracking requires higher frame rates for faster moving objects, in order to reduce the chances of false alarms.

Memory: An additional 10-100 MB of memory is required when used on a PC.

The resolution of the camera and the camera angle: Video analytic security cameras require a minimum pixel size of 15* 15. Resolutions much higher or lower than that can resulting in distorted images, often leading to false conclusions. The camera angle also determines the proper segmentation etc of the images.

Choosing the right video analytics for specific CCTV systems requires extensive research and very good awareness of the right kind of equipment suitable for your specific need. It is always advisable to seek the guidance of experts in the field who can assist you in identifying the right kind of CCTV equipment. Should you need any help in choosing your video analytics or CCTV system, please feel free to get in touch with our friendly team at CCTV4U.

Several external and internal factors can affect the performance of your video analytics system, so it is important make sure that special attention is paid to overcome all the constraints in order to reap the maximum benefits.

Environmental conditions: The changes in weather, lighting conditions and the presence of shadows can very much affect accurate detection when it comes to video analytics. It is therefore important to compensate for such conditions by going for appropriate CCTV equipment and filters for shadows and the varying light levels so as to get the best performance out of your video analytic system.

•    Compatibility: Another thing to keep in mind is that video analytics is not a stand alone technology. So it is very much important to see to it that it is compatible with your video equipment and network that the system is standards-based

•    CCTV Cameras: It is not always essential to go for the high-end cameras irrespective of the location you intend to place them in. Going for CCTV cameras that are most suitable for specific environmental conditions will not only yield the best results but also save you from unnecessary expenditure

•    User friendliness: User friendliness is an equally important aspect, as underestimating the training for your personnel could significantly impact on your budget.

Video analytics is one of the emerging technologies in the field of CCTV surveillance. When ordinary CCTV cameras themselves created a revolution in the security industry, the introduction of video analytics gave an all together new dimension to security surveillance. Rather than just capturing and recording the images, video analytics is capable of detecting, analysing, tracking and categorising the behaviour of people as well as vehicles. When earlier officials had to rummage through infinitly useless footage before finding any relevant ones during investigations, video analytics has made the task much easier.

Another advantage of video analytics is that the system continuously monitors all the images captured by the CCTV cameras, and alerts the operators only upon finding any objects of interest. Any suspicious behaviour or anything out of the ordinary immediately alerts the operators, helping them intervene before any damage is done. This is especially helpful for health and safety applications, detection of perimeter violation, people counting and for number plate recognition, and helps immensely in cutting down the cost of monitoring in the long run.

Options are galore when it comes to buying these gadgets, but it is getting to the right choice that is often the hard part. So, if you are thinking of getting a security camera system for your property, and are contemplating the video analytic option, please feel free to go through our online catalogue.
