Here at SecurityCameraKing.com, customers always want to know how to pick the best Security DVR to suit their needs and handle their analog security cameras.
Resolution is very important in viewing detail. For example, if you have an office building and you are robbed and need to see the details in the intruder’s face, then the higher the resolution the better. When you turn in your surveillance video to the authorities, you will want to give them the best recording possible. In addition to Security Camera DVR resolution, the frame rate is important for smooth viewing. The lower the frame rate in a recording, the fewer images per second are viewed and the viewing might be a little jumpy and erratic. The higher the frame rate in a recording, the more images per second are viewed creating a smoother view.

It’s all about the resolution and frame rates:

• Our Elite Series Security DVR records in D1@7fps on all channels
• Our Ultimate Series Security DVR records in D1@30fps on all channels
• Our Federal Series Security DVR records in 960H@30fps on all channels
• Our HD-SDI Series Security DVR records in 1080p@30fps on all channels

The Elite Series Security DVR

The Elite Series Security DVR is by far our most economical series in the Analog Security Camera DVR arena that we sell. Here is an example recorded video in D1@7fps shot with our 700TVL Weatherproof Varifocal IR Bullet Security Camera at the widest setting and recorded on our 4-Channel Elite Mini DVR . I am standing 25 feet from the camera:

From the above video, you can see that there is definitely a difference in the quality of the recording as opposed to our Elite Series DVR. There are over 4 times the images per second in the Ultimate Series than in our Elite Series Security DVR. You will notice as I am walking, it looks smoother at 30fps vs 7fps. Now, for an even better recording, you will want to take a look at our Federal Series Security DVR’s

The Federal Series Security DVR

The Federal Series Security DVR records at a whopping 960H at 30 frames per second, while giving you the ability to record in wide screen. Basically, it’s the same resolution as the D1 with the ability to capture a wider area, so that when you view the recording on a wide screen monitor, there is no loss in viewing are or distortion (which could occur with viewing D1 on a wide screen monitor. Here is an example recording from The Federal Series DVR in 960H@30fps shot with our 700TVL Weatherproof Varifocal IR Bullet Security Camera at the widest setting and recorded on our 4-Channel Federal DVR. I am standing at 25 feet from the camera:

The above video clearly shows that the Federal Series Security DVR can give you a great resolution recoding in a wide screen format without stretching or distortion. And, just because this DVR is called the federal does not mean it is only for the government. All different kinds of companies use these such as office buildings, schools and hospitals as well as government buildings. For the best that you can get with an analog cable system, it’s time to take a look at our HD-SDI Security DVR.

The HD-SDI Series Security DVR

The HD-SDI Series Security DVR records at a full 30 frames per second on all channels at a whopping 1080P! Now for the first time in the analog security camera DVR arena, you now can record in true High Definition Megapixel resolution without changing any of your old analog wires. All you have to do is attach HD-SDI cameras to this system…and keep your old wiring system! Here is an example of a recorded video from our HD-SDI Series in 1080p@30fps shot with our HD-SDI Box Camera and recorded on to our 4 Channel HDSDI DVR. I am standing at 25 feet. (Be sure to view at full screen and click on the gear icon and change the setting to 1080P).
Which one is right HD-SDI Series Security DVR
From the above video, you can see how recording in True HD produces an amazing quality video recording. Imagine (hopefully this will never happen) that you experience a vandal or intruder and wanted to see every feature of the assailant so that you can help the police in their investigation. The more detail in the recording, the more you can zoom in and see the detail. A tattoo, eye, color, scars are just some of the details that come to mind.
Here is another video at the same specs with the same system, and this time I am standing 50 feet away! (Be sure to view at full screen and click on the gear icon and change the setting to 1080P).
Which one is right Elite
In Conclusion:
To sum it up which Security DVR is best for you really depends on your budget and your security needs. If you have a bigger budget, the higher the resolution the greater detail in your recording. If you need an economical solution, you can still get away with a lower resolution and still be rest assured that even the lower resolution still has great features.
All of our Security DVRs have the benefits of being a stand-alone unit (meaning you don’t need to connect it to a computer and worry about viruses and people hacking into your system). The Linux system that runs our security DVRs is easy to use with the On Screen Display (OSD).

Network Security Camera

Written By:
Thursday, August 2nd, 2012

Although property crime statistics in the United States are steadily declining, according to Federal Bureau of Investigation, there is still a great need to safeguard your property. Whether you’re interested in adding security to your home or business, network security cameras continually monitor your property. While homeowners may feel security cameras are specifically made for businesses, by visually monitoring your home you not only ward off potential crimes by the sheer presence of the camera, but in the unfortunate event of theft or burglary the videos may help law enforcement identify and capture the thieves. Although there are a wide array of security cameras on the market, few offer the security and flexibility as network security cameras. If you’re in the market for security cameras, you should consider installing these items not only for their reliability, but also for the peace of mind their presence provides.

What is a Network Security Camera?

  • Network security cameras, also referred to as IP cameras, have the foundational purpose of traditional CCTV, or analogue, cameras; however, their method of sending and receiving data is much different. In a foundational sense, network cameras are quite similar to webcam as network cameras utilize the Internet to transmit and store recorded images. However, the similarities between webcams and network cameras end there. Network cameras are separated by two primary categories: centralized and decentralized cameras. The following are the two primary differences between these two camera setups:
  • Centralized Network Camera – A centralized network camera is one that requires a central NVR, or Network Video Recorder, to manage incoming recordings, video storage and alarm sounding if the cameras are attached to an audio alarm system. Commonly mistaken for a DVR, an NVR is a software program designed to record and store video from a network camera in a digital format. These digital videos are then saved to some form of digital mass storage such as a USB flash drive or an SD memory card. Although an NVR is solely software, the actual software is typically stored on a dedicated device that connects to various network cameras. The primary difference between an NVR and a DVR is an NVR receives its incoming video signals from an Internet network while a DVR receives its video signals from a direct connection to the camera. Another distinct difference between these software programs is how videos are processed and encoded. DVRs process and encode videos after they are streamed to the unit while NVRs process and encode video signals before being sent to the recording device.
  • Decentralized Network Cameras – A decentralized network camera is one that does not use an NVR. Rather, these cameras feature built-in video storage capabilities such as hard disk drives or flash drives. This form of storage is more streamlined, but features limitations such as not being able to store large quantities of data.
  • Types of Network CamerasNetwork security cameras are available in a wide array of formats and designs. However, while there are many designs there are seven primary camera types. Manufacturers may alter the features within these camera types; however, every network security camera is based in one of the following.
  • Outdoor Cameras – Designed specifically to be used outdoors, these network cameras feature weatherproof casings, significant temperature operation range, day and night recording as well as a tampering alarm. Typically used to monitor parking lots, campuses and traffic conditions, an outdoor network camera is ideal for areas that require 24/7 monitoring in all weather conditions.
  • Thermal Network Cameras – During moments of complete darkness, thermal network cameras are able to clearly capture images based on heat radiating from objects. All objects radiate a certain amount of heat, and this camera type is designed to capture the details from a heat source. The primary benefit of this camera design is its able to monitor property in complete darkness. Therefore, there’s no infrared LED lights illuminating the area. In complete darkness, onlookers are unaware they are being monitored. The downside of this camera design is its lack of detailing. While figures are clearly seen, small details typically captured by infrared security cameras are lost.
  • Megapixel Network Cameras – These cameras are designed to capture highly detailed images. Designed with the latest in high resolution surveillance technologies, megapixel network cameras, also referred to as HDTV cameras, can clearly record facial features or items a customer purchases.
  • Covert Cameras – As its name suggests, covert cameras are designed to seamlessly blend into its environment. Thus, onlookers are unaware of its presence while it continually captures their facial details and their actions. These cameras are ideal for monitoring customers in areas of a store that are unseen by wall or ceiling security cameras.
  • PTZ Dome Network Cameras – PTZ dome network cameras are designed to discreetly monitor a wide angle area. These cameras are housed in a dome, thus onlookers are unaware if the camera is pointing at them or not. The camera operator may manually tilt, zoom and pan while capturing high-quality video. Features typically found in these cameras include EIS, or electronic image stabilization, auto tracking and auto camera flip.
  • Fixed Dome Network Cameras – Like its name suggests, a fixed dome network camera does not offer lens movement. Rather, it is a fixed camera housed in a dome. The primary benefit of this camera design is its discreet design; however, the main drawback is its inability to interchange its lens. However, many fixed dome cameras offer a varifocal lens, which allows the field of view to be manually changed by an operator.
  • Fixed Network Camera – This camera design is perhaps the most common. Implemented to be visible to onlookers, a fixed camera cannot pan or rotate as its field of view is static. However, many fixed network cameras allow operators to change its lens. For example, a single fixed camera may be adjusted to house a wide-angle, telephoto or normal lens. Some camera designs are outfitted with a varifocal lens to adjust its field of view.

 

As stated earlier, these are simply the most common foundational designs. Each of the aforementioned is available in a wide array of configurations. To determine the best network security camera for your property, research available options and features. Remember, every property features unique monitoring challenges and the goal of a security camera system is to overcome these challenges for adequate monitoring.

Analog Resolution vs. Network Camera Resolution

Many property owners who are interested in security camera systems desire to have cameras with high video resolutions. The reason behind this is the higher the resolution the better the image quality. Cameras with low screen resolutions may capture the happenings of an area, yet if the images are blurry or fuzzy, these cameras do little to actually assist law enforcement in the apprehension of a criminal. Within the realm of security cameras, a major question is, “What is the resolution difference between traditional analog cameras and network cameras?” The recordable resolution of security cameras is dependent on the restrictions of the actual recording device such as a DVR for analog cameras or NVR for network cameras. With analog cameras, the DVR is restricted to a maximum resolution of 720 x 480 pixels. However, network cameras offer a wide array of resolutions. For example, many NVR programs support 5 megapixel, or higher, screen resolutions. This results in a video resolution of 2,592 x 1,944 pixels. Therefore, if image quality is paramount in your decision making process, network security cameras are your only option. Review various NVR programs, as some software programs may feature resolution limitations.

Benefits and Drawbacks of Network Security Cameras

As with any other form of security cameras, network security cameras feature benefits and drawbacks. Before making a purchasing decision, it is imperative you review the benefits and drawbacks to determine if the financial commitment of network cameras is worth the benefits you’ll receive.

Benefits

  • Installation Flexibility – Perhaps the most notable benefit of network cameras is its installation flexibility. Unlike analog security cameras, network cameras are able to be installed anywhere on a property where there is an IP network. This is not limited to Ethernet cable only networks. Many network cameras are able to operate and transmit signals through a wireless Internet signal.
  • Encryption – Securing the images of a camera is just as important as having a security system in your business or home. Network security cameras offer two layers of data safeguarding. Firstly, video images are encrypted before ever being transmitted to the NVR. Secondly, videos are automatically encrypted and authenticated through encryption languages such as WEP, AES, WPA and TKIP.
  • Video Resolution – As discussed earlier, network cameras offer significantly higher video resolution when compared to analog cameras. This increase in resolution provides clearer videos capable of identifying facial features and car license plates.
  • PoE Connectivity – Network security cameras do not need to be plugged directly into a power source. Rather, these cameras may operate by connecting the camera to a PoE, or Power over Ethernet, protocol. This system powers the cameras trough the Ethernet cable instead of through a traditional power source.

Disadvantages

  • Cost – If cost is an issue, then network security cameras may not be the ideal surveillance solution for you. Typically, network cameras require a higher upfront cost than analog security cameras. However, this disadvantage may quickly disappear as the use of network cameras increases. The increase in demand will likely lower the cost of these camera systems.
  • Video Interception – Although not very common, video signals may be intercepted if network cameras are connected through an unsecured wireless network. This raises the security threat as criminals could potentially access video streams and monitor the security environment of a business or home. This undermines the effectiveness of the cameras and actually facilitates a crime. Avoid this scenario by never connecting network cameras through a public, or unsecured, wireless signal.

While it may seem that the benefits of network security cameras far outweigh its drawbacks, it is important potential buyers seriously weight both the pros and cons before making a decision.

Closed Circuit TV Cameras

Written By:
Wednesday, October 19th, 2011

Nothing can provide the power of security and surveillance better than Closed Circuit Tv Cameras and their CCTV digital system.  Analog digital security provides adequate security and surveillance, but with the advent of the CCTV digital system there are far more beneficial features and options available.  In fact there are Closed Circuit Tv Cameras for just about every security or surveillance situation.

A standard CCTV digital system is based on components.  That means that individual devices (in this case the individual components) can usually be mixed and matched to adapt to a variety of uses to create the ultimate CCTV digital system.  The three components, Closed Circuit Tv Cameras, Digital Video Recorders or DVRs, and monitors provide the flexibility of versatile applications while maintaining the power and integrity of a single, complete and easily controllable system.

Closed Circuit Tv Camera systems are expandable so they are great for both residential and commercial applications.  Security Camera King offers the “Complete 16 Channel (i.e. 16 camera inputs) DVR Ultimate Security Camera Package with Bulk Cable” and their brand new Hybrid HD DVR as their finest, top-of-line digital system.  Although the Ultimate package can handle sixteen channels, and the Hybrid DVR can handle 8, which is adequate for most security applications, if more cameras are required, additional cameras with an additional DVR can be added.

Closed Circuit Tv camera’s have a wealth of features and options to make them applicable to almost any need.  In addition to the standard box, bullet, or dome shaped cameras CCTV digital systems can easily employ the use of covert video surveillance cameras such as hidden or disguised cameras.  This is possible because the digital cameras can be manufactured in such incredibly small sizes.

In addition, the electronic sensor inside the camera that converts the light energy emitted by the objects in the camera’s field of view can also inherently detect near infrared radiation.  In fact, most non-infrared cameras have an infrared filter over the sensor to block out the near infrared light.  This inherent ability to detect infrared radiation makes the camera an excellent choice for night time or total darkness video monitoring applications.  The camera’s sensor can detect the infrared light but it is invisible to the human eye.

Other optional features of Closed Circuit TV Cameras include using the Internet for networking cameras or DVR’s and for providing access to Closed Circuit TV Camera systems anywhere in the world that there is broadband Internet access and a suitable device (computer or smartphone).

Closed Circuit TV Camera systems can also have object tracking or following as part of the software that is supplied with either the DVR or Pan-Tilt-Zoom (PTZ) cameras.  Object tracking makes CCTV digital systems an excellent choice for commercial parking lots or for following individuals in open spaces.

Digital Video Recorders, like their analog ancestors the VHS or Beta video recorder, can store digital video files for later use or archiving, or can render them in real-time for live viewing.  Security Camera King’s featured DVR’s even have the ability to stream the digital images from our Closed Circuit Tv Camera digital systems over the Internet.  Unlike analog recording mediums, long-term digital storage media (CDs and DVDs for example) don’t allow the quality of the video image to degrade over time.

The third component of the Closed Circuit TV camera digital system, the digital monitor, has also offered vast improvements over its analog ancestor the CRT monitor.  Digital monitors can provide High Definition (HD) images or several camera images on just one monitor.  In addition, these monitors are much lighter so they can easily be wall or ceiling mounted.  Furthermore, they use a lot less power to produce their pictures than their older counterparts.

Finally, since every component of a CCTV digital system now operates based on digital data, many of the individual electronic parts of the system are the same parts used in the personal computer world.  Closed Circuit TV Cameras are similar to webcams; DVR’s are similar to computer hard disk drives; and security monitors are similar to computer monitors.

This provides for an enormous advantage over older analog systems.  Much of the equipment used in CCTV digital systems takes advantage of the vast technological advances that are made in the personal computing world.  Not only do the systems reap the benefit of technological advances, but the systems themselves are much more versatile in use and are lower in price.

Pan Tilt Zoom Camera

Written By:
Wednesday, March 30th, 2011

The Pan Tilt Zoom camera or PTZ is one of the most versatile dome cameras on the market today. Not only does it offer the standard electronic features of most other dome cameras, but the PTZ can do just that–Pan, Tilt, and Zoom.

In the video industry, Panning is the ability of the camera to about a horizontal plane, simply put turning from left to right and all the way around in a circle.  Tilting refers to the cameras ability to move about a vertical axis, once again simply put up and down.  With no walls, poles, or mounts to impede the view, a pan tilt zoom camera can easily maneuver its lens in any position equal or greater to that of an area covering 1/2 sphere.

In addition Pan Tilt Zoom cameras have the ability to change their focal length such to allow a field of vision that can range from “wide angle” to “Close-up” depending on the lens.  This lens movement and/or electronic (digital) action is called Zoom.

Pan Tilt Zoom cameras usually have a motorized mechanism that moves the camera about the axis, although some may also be able to perform these functions on a limited basis electronically.  When this technology is coupled with motion detection or object (shape) detection, the PTZ camera can be elevated in application from not only its PTZ functions but can also perform auto-tracking and following.

Security Camera King (SCK) offers a variety of Pan Tilt Zoom Cameras which range in price from $199.95 to $985.99.  SCK’s PTZ-LX550L3X is an affordable solution for a PTZ camera priced at $199.95 with a resolution of 550 TVL!  This camera has a 3X Zoom lens with 360 degree continuous rotation pan.  It can tilt from 0 to 90 degrees and flip.  The maximum pan speed is 60/sec, tilt 30/sec, and the present speed is 100/sec.

The PTZ-LX550L3X offers 32 preset points with pattern tours including programmable 16 preset point number and dwell time/speed.  The camera can auto scan as well as be programmed to auto return to its home position.  This camera is rated IP66 for outdoor use so it can be used as an indoor or outdoor camera.

Our PTZ-HN03100 is the perfect solution for a hands down high quality Pan Tilt Zoom camera that works well with any of our featured Digital Video Recorders or DVRs.  This camera is also a super high resolution camera weighing in at 540 TVL.  It is vandal proof, IP66 rated with the outdoor mount, has auto gain control, auto white balance, and an on-screen display.  In addition it offers 10X optical and 10X digital for a combined 100X zoom capability.

Next in line is our SVP-54CDN10X 540 TVL Mini Dome Surveillance Camera.  This is a Veilux camera and as many of our customers attest on their reviews, you can’t go wrong with a Veilux when it comes to quality.  This mini camera may be small but it delivers BIG results.  It offers true day/night with color day time video and black and white when the ambient light becomes less than .02 Lux.

This camera offers up to 256 presets and it offers high speed pan and tilt.  This camera even comes with its own wall mount!  Priced at $664.50 it’s a professional level camera that offers professional results.

SCK offers two different models of auto tracking Pan Tilt Zoom cameras.  The first, Product# VP-ATDNC27X is priced at $707.69 and includes day/night capture and 27X zoom.  Once again this is a Veilux brand camera and stands for high quality.  The second model is SCK’s SVP-ATDN36X and is also a Veilux camera similar to the first with the major difference being an increase in zoom capability to 36X.

Regardless of the model you choose, a Pan Tilt Zoom camera is a versatile, powerful, and cost savings camera.  When these camera are placed properly, one camera can easily replace the need for 2, 3, or 4 otherwise stationary cameras.  In addition, if standard non-PTZ cameras were used, these Pan Tilt Zoom Cameras also offer the powerful zoom function that allows you to get in close.

If you are interested in purchasing a Pan Tilt Zoom camera or would like more information, please contact one of our Security Specialists today.
