All About Thermal IR PTZ Cameras

Everything above absolute zero (-273C) emits thermal IR radiation. The Ranger thermal camera converts this into a digital image that can be displayed, distributed, and recorded. Humans, animals, and vehicles are very hot in contrast to a background and trespassers hiding in shadows or bushes are easily spotted making thermal extremely effective and can be used with AVA Infiniti video analytics for automated intelligent solution.

Optical Day/Night Camera
The RNG-37X-TI has 5mm optically pure, flat tempered glass eliminating distortion and blurring to further enhance image clarity, even when zoomed in. The OSD allows you to program the Wide Dynamic Range (WDR), backlight compensation, privacy zones, and virtually every aspect of the camera allowing it to be installed in any application. All these features, in tandem with the accurate pan/tilt drivers, allow the RNG-37X-TI to capture minute details at great distances.

Pan-Tilt Resolver
The heavy-duty PTZ driver is designed for extreme performance in the most demanding applications. It implements brushless motor technology for endless 360¡ã panning and Micro-Step technology for precise (0.10¡ã) pan and tilt positioning. Advanced features, such as preset and auto-cruise, will complement almost any existing equipment by means of Pelco-D and Pelco-P protocols.

Intuitive and User Friendly
Although the RNG-37X-TI is an extremely sophisticated piece of equipment, it is operated by an intuitive, user friendly interface with multiple control options such as touch screen and mouse. It can also be controlled by a 3-axis joystick and operated by any individual without prior training. Additionally, the optional Image Stabilizer (IS) and fog filter helps eliminate the effects of vibration and waves giving the Ranger similar performance of a gyro-stabilized system at a fraction of the cost.

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.

The Features Of Megapixel And Digital PTZ Cameras

The Features Of Megapixel And Digital PTZ Cameras

PTZ’s are a great addition to any security camera system. The key question that you have to ask before you purchase one is… do I need it?

PTZ stands for Pan Tilt Zoom. PTZ cameras can be instructed to pan back and forth, tilt up or down, or zoom in or out. The cameras are controlled locally with a joystick, or remotely via the internet or smart phone application.

This is a truly a great feature in a camera. But a PTZ camera does not solve all your surveillance problems. We have seen many security camera systems that depend too heavily on their PTZs. One obvious issue is that the feature is only useful if a person is available to monitor and adjust the PTZ as needed. Some installations set up their PTZ camera to automatically pan back and forth. But that doesn’t help much if an event occurs outside of the camera’s field of view at any particular moment. Another option to address this issue is an ‘autotracking’ feature which uses analytics to instruct the camera to track and focus in on movement within its field of view. But the autotracking functionality is not fool-proof, and adds cost.

So we recommend that it’s best to think of a PTZ as a bonus camera in your system. Cover all of your area properly with fixed cameras, and then add a PTZ as the “cherry on top”. Now you have proper coverage of all your area and still have the ability to PTZ around your property, either locally or remotely.

Cost of PTZs

Many people think they can save money using a PTZ because it can cover more area. But, PTZs typically cost about 3 or 4 times that of fixed lens camera so they don’t save you money. Plus, since PTZ cameras have moving parts in them they require more upkeep and may not last as long as a fixed lens camera. Maintenance of PTZs might include dome cleaning, belt replacement, and replacement of motor controls, RS485 data board, or zoom module.

Megapixel and Digital PTZ

One last thing to consider is megapixel (mp) cameras. Megapixel cameras record at a much higher resolution than analog cameras and offer a feature called ‘digital PTZ’. When you record a 5mp camera at 2560×1920, you have a lot of pixels that you can digitally zoom in on and move around like a PTZ, both live and during playback. As megapixel cameras become more ubiquitous and affordable the ‘old’ style PTZs will be less desirable.

Conclusion

If all this sounds like we’re trying to talk you out of purchasing a PTZ, we’re not! You just need to be aware of the advantages as well as the drawbacks of using this type of security camera.

The Market trends Of IP cameras and PTZ Cameras

The Market trends Of IP cameras and PTZ Cameras

IP cameras are also becoming commoditized

IP cameras are becoming commoditized faster than analog. It took about 15 years for pan-tilt-zoom (PTZ) domes to be commoditized, and IP cameras are getting commoditized after five or six years. So where is the differentiator? It¡¯s not the cameras, but it comes down to customer service. How do you serve the customer? We are an end-to-end service provider. When you provide an end-to-end solution, you can provide more value, which fights against commoditization.

For the bottom of the market, we are going to have a service-based model with our cloud solution. It¡¯s not about the cameras and features, it¡¯s what service you are providing and at what price and the level of service. At the commoditized bottom of the market, we are offering the hardware and the service, and leveraging our channel to bring solutions to the market.

It seems 360-degree surveillance cameras are gaining momentum.

Number one, the technology has made tremendous progress, and you¡¯re getting the picture quality you need from a technology point of view. Customers are starting to realize that indoor PTZ Cameras applications only fulfilled one part of their need. The cameras never looked at the right place at the right time, so efficiency has been a question. Reliability of mechanical parts has been a problem. Today, with 360 degree cameras, because of the resolution we have now, it may be a better indoor solution instead of a PTZ dome. Will it replace all of it? Probably not. For situational awareness, it is definitely a better technology. Now those products are taking off, and that aspect is growing very rapidly.
