Video Surveillance in Schools

The objectives of the surveillance system in a school

The crimes that take place in schools usually misdemeanors, such as theft of clothing or other personal belongings, extortions of small sums of money, bullying of younger students by older ones. But the number of serious crimes, including beating and pushing drug crimes also become a growing problem. Most people understand that even better educational measures can not solve the problem requires a complex action. One of effective methods to improve the security level in a school target = "_self" title = "CCTV, IP CCTV"> CCTV surveillance system, obviously, reduce the number of excesses.

Logged events can often the only evidence that witnesses usually do not want to "bear witness" against their peers, due to fear of rejection, or just for their own safety. Besides improving security, CCTV monitoring helps protect school infrastructure and equipment against vandalism, a plague of most contemporary schools.

Diagram of the surveillance system in a school

The principles
Both education authorities and the design firm and project implementation should realize that such large buildings / s with a large number of rooms and many accessories as well as financial limitations, will play an important role the scope and precision of the system. In the first place – should ensure a general inspection, and only some important sites are equipped with devices that allow for accurate identification of individuals.

To control what and how?
First, must have complied with all possible entrances to the school. The equipment used in places that should ensure the unequivocal identification of people entering. Cameras have to be put near the entrances or be equipped with large focal length lenses. It will guarantee that the recorded material will give detailed information on the appearance of all who enter the school, including foreigners.

Hallways and locker rooms are places where the cameras are coming indispensable. The cameras should be placed as high as possible – ensuring the broad area of observation (without blocking the view of one person by another – is often a multitude of people there), and helps protect your camera against damage.

Brokers are often long and narrow – the issue requires a series of cameras. Must be arranged in the way each camera sees the following (for example, are at opposite ends of the corridor). It will allow recording of possible attempts to destroy the cameras.

The most debatable whether cameras should be mounted or not, refers to bathrooms and toilets. From the standpoint of the principal rooms are very vulnerable to vandalism and various excesses. They are often considered by students to smoke.

Taking it into account, most schools CCTV surveillance assembly in that country. Monitoring provides an overview of the main part of the room but the inside of the cubicles is excluded from observation. This control task (it is even possible to find a smoker, because of the rising smoke) and do not invade privacy people. The level of monitoring should be discussed with parents (eg, acting on parent-teacher association.)

In these small places are not used dome cameras, for example, M10744 and M10746 (IR). Similarly the most popular cameras are the models with adjustable viewing angle – V-CAM 600 M10600

M10746 dome cameras in vandal-proof boxes are well prepared to work within schools

The last area that should also be controlled is a school environment, ie, playground, sports fields, pool, parking, or other places frequented by young people.

Due to limited number of cameras and large monitored area, the role of supervision is usually to give an overview of the area, unable to accurately identify. To improve the basic level of utility is important to use the color system increasing recognition accuracy.

"Secret Weapon" – Simulated Camera
A vital element of every surveillance system especially this type, is the psychological aspect. The thought of being watched makes people behave properly, in a cultural manner. This fact should be used for " intensification "of the existence of the visual system with a number of dummy cameras, mounted in less critical. This popular method of deterring potential offenders significantly reduces the cost of installing a whole, but is very effective when the dummies are realistic – the ideal solution requires visual products identical to those being operational.

Election of the cameras – B / W or color
As mentioned, the images color ensure better effects with regard to the identification of individuals.
On the other hand, B / W system is more sensitive and easier to adapt to the observation night.

Low sensitivity of color cameras is usually not a problem for this type of installation where space is illuminated at night. The lawsuit, observation night, ie, it is possible with B / W cameras because their spectral response characteristics and the use of infrared lamps that allows viewing discrete dark areas, can also be easily performed with appropriate color cameras.
Proper color cameras switch in the dark mode B / W and sensitivity gain. To be used for monitoring with infrared lighting, and camera SN-486C, M11202. The cameras are ideal tools for monitoring playgrounds, sports fields, parking, etc.

M11202 camera color day / night is an ideal device for outdoor applications.

Most cameras offer is equipped with electronic iris control, change its sensitivity depending on current lighting conditions. The cameras are capable of working with moderate changes in light, for example, inside a building, using cheap lenses without iris adjustment. However, the cameras operating outside of a building must be equipped with lenses with Auto Iris, which allows a good quality images even in very changing light conditions, exposure to the sun for almost complete darkness.

Appearance and camera mount
Due to the nature of the monitoring sites (With young people having a lot of energy), the cameras can be exposed to accidental or intentional damage. To restrict direct access to a camera should be mounted as high as possible, with the use of additional housing that will prevent anyone from manipulating the device. You should not use solid supports, for example, insensitive a batted ball. The preferred class (…)
