Description

Monitoring device for construction sites Technical field of the invention The present invention pertains to the technical field of security and video surveillance systems used to protect the interests of companies and individuals, specifically to a surveillance device for construction sites. Background of the Invention Construction sites are often targeted by thieves because they use valuable materials, machinery, and tools. Therefore, they require adequate security measures to prevent theft and vandalism and allow work to continue smoothly. Traditionally, security measures consisted of alarms and surveillance cameras distributed throughout the construction site, or even the presence of security guards. These systems have many weaknesses that allow offenders to find ways to access the property and steal goods to varying degrees. Currently, there are temporary security devices consisting of video surveillance towers with cameras and an alarm system to alert if the presence of an unauthorized person is detected. These towers are movable to allow relocation to any location on the construction site if necessary, with the aim of enabling control from a complete view of the entire site. Although it is a device that allows for a higher level of security, it still presents certain drawbacks, since the structure changes over time, so it is necessary to keep relocating the tower in search of the best place for greater control. However, it is not always possible to find a place that does not have blind spots for the cameras, especially as the elements of the work and its extension increase. Furthermore, the control of this device focuses on visual surveillance of the area through cameras, which may also have audio control, but there is no perimeter protection of the area, so early detection of intrusion will not be possible. It is therefore necessary to find a way to reinforce these surveillance devices so that complete security of the area to be monitored is provided, detecting any attempt at unauthorized entry from the very moment it originates. Description of the invention The construction site surveillance device, comprising a watchtower with at least one first vision camera, an alarm and power supply means, presented herein, comprises four first infrared sensors installed in the tower and configured so as to allow control of a first protection zone around the tower. Furthermore, the device comprises at least a first set of six or more posts with a height greater than 1 m, located around and separated from the tower, each having at least a second infrared sensor, where the sensors are configured to allow monitoring of a second protection zone around the tower, where the second zone is located after and overlapping the first protection zone and where both protection zones have a closed perimeter. In this device, it is fulfilled that the union of protection zones covers the total surface of the work. The device also includes a concrete slab for fixing the watchtower and anchoring means configured to allow the movement of both elements by crane, as well as means of connection to a control center. For its part, the watchtower comprises a telescopic mast that allows a tower height of more than 5 m, at least two first cameras that have a resolution greater than 1080 pixels, at least one second thermal camera and at least one third camera with 360º vision fixed by its lower end at the upper end of the telescopic mast. These cameras feature artificial intelligence and a range of between 50 and 200 m. The tower also includes connectors capable of allowing the connection of at least fifty additional devices. The construction monitoring device proposed here represents a significant improvement over the state of the art. This is because an advanced video surveillance device is obtained with high-tech cameras that feature artificial intelligence. In addition, one of the cameras is a 360º vision camera and is located at the top of the mast, without side supports that could obstruct its field of vision, thus guaranteeing real coverage in all directions, without blind spots. The tower is centrally located and anchored to a concrete slab for stability. Equipped with anchoring points for crane transport, it can be moved once the surveillance service ends, but while in operation, it remains completely stable and resistant to tampering. A major advantage of this surveillance device is its infrared sensors, which provide a very high level of security. Four of these sensors are installed on the tower itself to monitor for any unauthorized access and prevent tampering. Furthermore, this infrared detection is reinforced with infrared sensors arranged on poles that are placed forming one or more rings of different diameters around the tower, achieving protection zones that overlap each other to cover the entire surface of the work. One advantage of this device is that it is expandable according to the needs of the place to be monitored or the growth of the work and the presence of elements and parts of it, since the central tower has connector means prepared for the connection of fifty or more devices, which allows expanding the protection with all those devices that are deemed necessary depending on the type and specific characteristics of the work. It is also an energy-independent device, and the possibility of increasing the number of solar panels makes it an option adaptable to different environments and needs. It is therefore a very effective, expandable and versatile surveillance device with which it is possible to control the entire extent of the work to prevent any improper access to it. As an added advantage, this device is linked to a security company, which allows for the provision of on-site assistance from security guards with immediate response service who will come to the construction site if necessary, without having to contract this service separately, thus obtaining a comprehensive security device with enhanced effectiveness.
