A Video Surveillance System Is Important On College Campuses

A Video Surveillance System Is Important On College Campuses

A video surveillance system is important on college campuses. It assists to provide security for the diverse assortment of facilities on the campus as well as to protect students, who sometimes make long journeys within the campus ground at night. However, before installing video surveillance cameras on the campus, there are issues to be addressed. What security system is on ground? What are the security concerns on the campus? How will installing video surveillance cameras fortify security? A few tips about installing video surveillance cameras on campus grounds will address some of these issues:


The location of video surveillance cameras is extremely important to a successful security situation on the campus. Video surveillance cameras are not to be positioned without deep thought. They are effective when they are placed at exits and entrances of buildings, at parking lots, campus stores, cashiers office, sports ground, lobbies, stairways, and at auditoriums.


A university campus comprises of dormitories, libraries, sports complexes, school fields, faculty buildings, etc. Since there’s a lot of space to cover, the security system to monitor this vast expanse of land must be all-embracing. Remote monitoring enabled through the installation of IP cameras to a video surveillance system will enhance the complex security needs of the campus. Another advantage of an Internet angle to security is that archived footage becomes possible, and this can be used to investigate past criminal and violent act.


There is no doubt that video surveillance cameras should be installed on public places on college campuses. This assists to deter criminal activities. But the installation should not lead to the invasion of the privacy of those living in the university community. People living on the campuses are usually critical. Their opposition to the installation of system on the basis of invasion of privacy might derail the entire project and the essence of the initiative will be defeated. In other words, keep the privacy of students, lecturers, non-academic staff, and others in mind while putting in place video surveillance cameras. For instance, the cameras should not cover the halls of residence and the staff quarters.


While the presence of video surveillance system gives the impression that the security situation has been taken care of, this may be an illusion. Security issues are much more complex than that. In other words, the traditional forms of security provision should be maintained to work with the cameras. Campus security personnel and other law enforcement agents should still continue to function. Members of the university community must remain vigilant and ready to take care of their personal security as well.

Video Cameras Are Designed For Amateur Photographers And Household Uses

Video Cameras Are Designed For Amateur Photographers And Household Uses

Cameras have been widely used over the years to capture precious moments. However, these photographs were able to record only a few single moments of life. The need for continuity in recording events led to the invention of a video camera. Unlike traditional cameras, which use photographic film, video cameras use entire videocassettes to capture electronic images of entire events.

Initially, video cameras were designed to facilitate television broadcasting. A few decades earlier, video cameras were exceptionally large devices. It was necessary to fix them on big trolleys in order to be able to use them. In modern times, smaller varieties, which are portable and can be carried easily, are widely available.

There are two types of professional video cameras available. The primary kind looks like a big camcorder and is highly developed and portable. The other type can be referred to as studio cameras and do not have endless recording capacity like the former.

Camcorders are video cameras that are designed for amateur photographers and household uses. Before the camcorder was developed, people used special video cameras and VCRs to replicate video recording. These were less advanced and designed to cater to consumer usage.

Camcorders derive their name from a unit, which houses a camera and recorder. Camcorders have evolved with time and now come in more compact, lightweight and user-friendly models. These new cameras can record for several hours on end. The recording is done either on a small videocassette, blank CD or a DVD. In some cases, a LCD screen is present for the user to preview the recording.

A third type of camera, called closed-circuit television, is also very popular. As the name suggests, these devices use a camera and television assembly to monitor a certain area or people. This type of surveillance is common in areas that require additional security such as banks and airports.

The Importance Of Installing PTZ Security Cameras

The Importance Of Installing PTZ Security Cameras

PTZ security cameras are one of the more versatile and feature rich types of surveillance camera; and yes they are also one of the more pricey options as well. A lot can be done with a PTZ security camera; so let’s take a look at what they are, and what some of their more creative uses might be.

With criminal activities becoming more and more common everywhere around the globe, security has become our main concern. Are we safe? Is our home safe? Is my business absolutely secure? These are some of the questions that are always plaguing us. We are never really quite sure about whom to trust and whom not to. It is these questions and worries that have made us turn to the security cameras systems. In these strange times, it seems like only high-end surveillance systems can ensure whether we are absolutely safe or not. Yes, it is true that the presence of a security camera cannot physically stop a crime from taking place but its presence is enough for the criminal to realize that he is being watched. With this awareness in mind, fewer people will dare to go ahead and commit an illegal deed. Nowadays, the CCTV cameras are noticed everywhere from hospitals to warehouses, from schools to universities and from homes to business establishments. In some cities, these cameras are also installed at the busy road signals.

While most people do realize the importance of installing the security camera systems in their homes and offices; they are often at a loss when it comes to deciding what type of camera they should buy. There are plenty of choices available in the market and almost each one of them has a unique benefit. One of the most popular kinds of these devices is the Pan-Tilt-Zoom camera. It is more commonly known as PTZ camera. These are high-tech surveillance systems which are used in big business establishments and are often noticed in and around government properties too. These cameras have been used by businesses since the time of VCR-based analog systems. But, be assured that they are in no way primitive. The PTZ cameras have only improved over the years and have managed to uphold their popularity even in this super fast digital age.

The PTZ security cameras systems generally are a bit bigger in size than the dome or bullet cameras. However, the PTZ cameras are much more flexible as they can focus on more than one location and are able to zoom in and out in order to capture specific objects or events. Although these cameras are not usually weatherproof, they can still be placed outdoors inside a bracket with in a black-glass dome. This will not only increase the durability of the cameras but it will also deceive the subjects. These systems require proper monitoring and configuration that bring out their true potential. These are best used during the recording of live situations. If placed in a closed corner they will have a 90 degree surveillance angle, but if placed in an open area, these cameras will have a 360 degree surveillance angle.

Another attribute of PTZ Security Camera Systems is that they can zoom in up to 300 yards and more. Then again, you will not have to worry about low-light areas because these Security Cameras Systems have a low lux setting which enables the cameras to capture and display clear images that are located in the low lighted areas and shadows.

PTZ Cameras Are An Excellent Choice For Business Security Camera Installations

PTZ Cameras Are An Excellent Choice For Business Security Camera Installations

PTZ Cameras are an excellent choice for business security camera installations, because it will allow you to control your camera. This way, you can visually patrol your business or zoom in on things that are occurring at your facility while they are happening, but keep in mind that the camera will be limited to the footage that it is seeing at the time of the activity. So it is a good idea to have a guard position for your camera that will provide a good overall view of the area of your business. This way if something occurs, the camera is not looking in the wrong direction…and if you are watching the camera at the time that something is happening, you will be able to control the camera and zoom in on license plates, people, vehicles and more, to provide even better video footage of what is happening.

What Is A PTZ Camera

To begin you need to know what a PTZ camera is. PTZ stands for pan, tilt, and zoom; and a camera that can perform these functions automatically or remotely falls into the category of a PTZ camera.

Most PTZ cameras are styled as a dome surveillance camera; as that design in much easier to incorporate these features into; however there are what is known as PT heads that can make any plain security camera have at least the pan and tilt functions.

As I stated earlier to fall under this classification, the security camera must be able to perform these functions remotely or automatically to truly be considered a PTZ. If you have to manually change you focal length and viewing angle; then this describes just a plain security camera, and does not fall under the PTZ classification.

To perform these various functions the camera will most likely use what is known as the RS485 protocol; and you should make sure that you have a controller or DVR or receiver that can use this protocol.

Creative Uses For A PTZ Security Camera

The most basic uses for a PTZ camera is the ability to have your camera continuously pan or tilt in a designated location to cover a wider area than your lens might allow.. Furthermore you can then incorporate the zoom feature to get a closer view of trespassers or other items of interest. These cameras are especially useful in highly trafficked areas such as casinos; as they can quickly be adjusted at a moments notice.

One way that PTZ’s are used is in public access governmental meetings. A lot of commissions such as county or city commissions will use an array of PTZ cameras to record various angles of their meeting, and then broadcast it to the local television channel. In fact a switcher will even be incorporated at times to direct and make sure the cameras are capturing what they need to.

Another interesting way that some people will use a PTZ camera is for watching wildlife. Some PTZ owners will use their PTZ to monitor their hunting bait piles or other wildlife scenery; as it is less intrusive and disturbing than having a human presence.

What Is The Allure To The PTZ Cameras

What Is The Allure To The PTZ Cameras

What is the allure to the PTZ Cameras? The original benefit to analog recorders of covering more area with a single camera has been rendered less than necessary on newer digital recorders. So business owners should determine how they will be using the PTZ Camera to determine if a PTZ Camera is the best solution. PTZ Cameras connected to PC-Based or Standalone DVRs provide the ability to move the camera and zoom in on specific activities while they occur. Unlike VCR based systems, you do not necessarily have to be stationed on-location in order to accomplish this. Many systems, like our Alnet Systems PC-Based DVR Cards, will allow you to move the PTZ cameras and zoom in on what is occurring even from a remote location over the internet. The Alnet Systems PC-Based DVR Card/Software combination will even allow you to control the live PTZ camera from a Laptop, PC, Windows Mobile PDA Phone or even Windows Mobile Smartphone. The ability to move the camera live while on-location or off, allows you to get more relevant video footage of what is occurring. This allows you to leave the PTZ Camera at a pre-determined “guard” position with a wide view of the area, but zoom in on something as it is occurring for better footage of the incident.

You need to keep in mind when installing the PTZ Camera that it will not be able to provide more detail of an occurrence than what was in view and recorded at the time when the activity was occurring. For instance, if your PTZ Camera was set to a wide-angle guard position while someone was breaking into a car in your parking lot, the recorder will only have the footage from the angle that the camera was pointed at during the time of the occurrence. In other words, a digital zoom after the fact will not provide the same quality footage as an optical zoom (controlling the camera during the event). A digital zoom after the fact, will only make the pixels larger on the screen – the further you zoom in, the larger and blockier the pixels become. But with today’s digital video recording systems, you can easily monitor your camera right on your PC, while you are working or even while at home, and can control the camera with easy PTZ Controls. This way, as long as you are connected in to your cameras, you can use the optical zoom of your PTZ Camera to zoom in on what is happening in the area covered by your PTZ Cameras.

VCR-Based Analog Systems And PTZ Style Security Cameras

VCR-Based Analog Systems And PTZ Style Security Cameras

PTZ (Pan/Tilt/Zoom) style security cameras have been a mainstay of business security camera systems since the days of VCR-based analog systems, and have continued in their popularity into the digital age of security. However, the reasons for the PTZ Cameras, and the benefits have changed over the years. Many business owners might expect too much out of these PTZ Cameras, or might expect the wrong benefits. It is important to know what a PTZ Camera can add to you business security camera system before taking these cameras into serious consideration.

Originally, in the days of VCR based Analog recording from business security cameras, the PTZ Camera was used prevalently as a means to offer coverage of more area, without having to add extra expensive equipment. These PTZ Cameras could be set to pan and tilt, as well as zoom along a pre-determined path continuously, providing coverage of an entire area. This type of PTZ Camera was developed with that purpose in mind, and served its purpose very well in business security camera systems with analog recorders. These analog VCR recorders could only accept a finite number of cameras, and would split resolution across the connected cameras through use of a multiplexer. Adding cameras to these systems would involve addition of expensive multiplexers, additional time-lapse VCR recorders and other equipment, so it was often easier to simply install one PTZ Camera to cover the same area that could otherwise be monitored by 3-4 stationary cameras.

However, with the advent of Digital PC-Based or Standalone DVR recorders that can be used for business security camera systems, the role of a PTZ Camera has shifted significantly. These digital recording systems generally utilize a motion detection recording, to help conserve on recording space, allowing for longer recording times on the recorder’s hard drive. However, if a PTZ Camera is set to an Auto-Tour on a digital system, this camera will always be triggering a continuous recording, using up precious hard drive space in the process. With Digital PC-Based or Standalone DVR Recorders, adding extra stationary cameras is not difficult at all, as digital systems can generally be upgraded without major expense, so providing adequate coverage with stationary cameras is usually far less expensive even than installing a single PTZ Camera.
