Construction Site Camera

Monday, June 27th, 2011

Why would anyone want to use a construction site camera?  Can it stop theft of materials and tools?  What kind of camera is it?  In the following article we’ll answer some these questions and more, so read on.

First, “Why would anyone want to use a construction site camera?” and “Can it stop theft of materials and tools?” kind of go hand in hand and both questions can be answered with one answer.

A construction site camera can help prevent theft of materials and tools, but admittedly it cannot stop the theft of these things.  However, law enforcement agencies around the world including large cities like London, England and New York City have documented reduced crime in areas of digital video surveillance cameras.  In addition, it has been shown time and time again that a digital video security and surveillance system does deter perpetrators with negative intentions.  What’s that saying?  “An ounce of prevention is worth a pound of cure?”

Not only can a construction site camera be used to deter theft and trespassing of unauthorized individuals, but it can monitor the construction crew during the day to help document any injuries or other problems during the work day.  A workers compensation claim can be very easy to deal with when the event is all digitally recorded.

Finally another good reason for using a construction site camera is to monitor large construction projects that may take an ample time to complete.  Nothing impresses construction company clients more than to say, “You can view the progress live on your computer if you like.”

So, have we answered the question, “Why would anyone want to use a construction site camera” yet?  As you can see there are a lot of applications for a surveillance camera in the construction industry.

Now the next question comes to mind, “What kind of camera is it?”  Not so much is the question “What kind is it?” but more like “What kind do I need?”  There are three basic types of digital video camera to choose from, which one is the best r construction site camera is more of a personal issue; if you know a little about the cameras than you can determine which camera is right for you.

There are basically 3 types of cameras based on shape; anyone of the three could be used as a construction site camera.  Box security cameras are very popular because the are vary versatile.  For a box type camera you must purchase the lens separately but this is actually beneficial, allowing you to change the camera to fit each different construction site’s requirements.  You will also need to purchase an outdoor housing for these cameras are made for indoors (unless they have a housing).  Box cameras are placed inside the mounting and the mounting is attached to a secure, solid surface.

Bullet security cameras make excellent construction site cameras.  Most bullet cameras are designed to be indoor/outdoor cameras so there is no need to purchase an extra housing.  Also, most bullet cameras have pre-installed arrays of InfraRed Light Emitting Diodes or IR LEDs which illuminate the camera’s field of vision even in total darkness.

What’s even better is that the human eye cannot see this type of infrared light but the camera sure can.  However, also be aware that infrared mode video images will be in either black and white or monochromatic.  But the high detail video image that you saw under daytime lighting conditions will not be downgraded at all.  This infrared technology is especially helpful at large construction sites (such as those building large and tall buildings, very open areas, and areas that may not be that easy to get at).

The third type of camera is the dome camera.  A system of dome cameras could make very useful construction cameras.  The can be mounted just about anywhere and can come with additional features like infrared technology, Pan-Tilt-Zoom movement and even object tracking and following.  The best type of dome camera to consider for this case is a vandal resistant camera.  They’re the best suited dome camera for this purpose not only because of their tough, rugged design but because they too can take excellent video shots.

Construction Site Security Camera Surveillance

Friday, December 17th, 2010

If you are looking to increase security in your work zone, consider using construction site security camera surveillance. Digital video security camera systems can help prevent theft of construction site materials, notify you and help prevent intrusion by trespassers, and even monitor the site for safety issues during the work period. In addition, construction site security camera surveillance is an excellent means for providing owners/investors with the ability to follow progress as the construction project proceeds.

Before the technological advances in the digital security system industry, it may have been difficult and costly to obtain construction site security camera surveillance. However, with the advent of new technology including digital video cameras, wireless technology, and Internet Protocol (IP) ready systems, construction site security camera surveillance is reasonably priced and easy to provide, and easy to install.

For particularly large construction jobs, the use of construction site security camera surveillance can reduce or eliminate the need for security guards or a security team. In addition, large jobs can have several cameras or if necessary, multiple systems to provide complete perimeter and site surveillance; indoors our out.

There are so many different types of cameras and systems available that their application is incredibly versatile to the point that there are very few construction site applications where construction site security camera surveillance can’t be used. Let’s take a look at some of these security camera system features and how they can apply to a construction site.

Generally, the number of cameras (also called “channels”) available in a given system is determined by the DVR. The most common DVR types can accept up to four, eight, or sixteen camera inputs. One of these DVRs should accommodate your needs, however if you require more than sixteen cameras, two or more systems can be setup in tandem.

Digital video security cameras require a power supply and a video transmission cable (usually an RG-59 coaxial cable) that must be run from each camera to the DVR. If these cabling hookups aren’t practical for your situation, wireless battery operated cameras can be used instead. Wireless cameras contain their own built-in transmitter and on board antenna that is used to send the video signal via radio waves to a corresponding receiver.

Wireless cameras make use of a variety of different wireless technologies but probably the most common type used today is the 2.8 or 5.8 GHz technology. This is the same technology used to transmit wireless land-line based telephone conversations. It’s incredibly effective and free of interference and can have a relatively long range. Some wireless cameras boast up to a two mile range to the receiver.

These ranges are called “Line of Sight” or LOS ranges because the range specification given by the manufacturer is based on a transmission route between the camera and receiver in a line of sight, meaning without any obstructions between the two. Although objects within the LOS generally reduce the effective range, they seldom prevent reception. If there is an obstruction, the material of the object will determine the reduction in range. Be certain to check the range of wireless cameras before purchasing them to make sure they meet your specific range requirements.

In addition to the wireless transmission feature, some cameras can be operated by batteries (either rechargeable or disposable) instead of a power supply plugged into 120 volt AC service. Even better, cameras can also be purchased with an on-board motion detector.

Construction site security camera surveillance is generally concerned more with activity than non-active video so the motion-detector wireless battery operated camera is an excellent choice. The motion detector is a PIR (Passive InfraRed) sensor that can detect the change in infrared signatures in the camera’s field of view. If a change is detected, it is assumed that this was created by some sort of motion and the PIR connected internally to a relay in the camera housing, turns the camera on to record. The PIR sensor uses significantly less battery power than the camera, increasing the usable life of the batteries.

There are many other options available for construction site security camera surveillance. Night time infrared cameras can record activity using an infrared light source which is invisible to the human eye. Pan-Tilt-Zoom (PTZ) DVR programs with PTZ cameras can actually track or follow an object or person.

Construction site security camera surveillance is a cost-efficient time proven method for preventing and documenting theft, vandalism, and even accidents. This is one tool your construction site shouldn’t be without.
