There is a new line of High Definition 2 Megapixel IP Security Cameras here at SecurityCameraKing.com, our TP Series. These IP cameras can deliver an amazing, crisp detail at 1080p True HD that is far beyond the quality of other security cameras. The TP series of HD Security Cameras are offered at a competitive price point that makes IP Megapixel Cameras affordable to the end user.

The reason why 1080p is so important in home, retail and government security (to name a few environments) is the clarity of the video. Most security systems out there are made up of Analog DVRs and Cameras and recording at D1 (720 x 480 pixels). Our line of TP IP cameras record at 1080p (1920 x 1080 pixels). The difference in size allows you to zoom in without the image getting distorted (or pixelized). I had a customer call the other day and say that he was reviewing some footage of a break-in and wanted to zoom in on the burglar’s tattoo but the image was so distorted it was not detectable. I asked him if it was an analog camera that captured the footage and he said it was. I told him that 2MP IP Camera would capture a better image since there is less distortion when zooming than an analog camera. Next time it could mean an arrest. He was sold and upgraded his whole system to IP.

What makes this 2MP Bullet Security Camera so amazing is not only can it record at 1080p, but it can manually zoom and see at night up to 150 feet!. But, the only thing is when you take the camera out of the box you might think to yourself, “What are all those freaking wires coming out of the camera?” No fear, I will give you full rundown of what they are.

A. This is the 12vDC Power port. This camera can be powered with either PoE (Power over Ethernet) or 12v DC.
B. This is a USB Port for a Thumb Drive. You can use this camera as a stand-alone camera to record your surveillance without the need of an NVR (Network Video Recorder).
C. This is the Alarm in/out port. You can set up triggering events coming in from devices such as a PIR sensor which tells the camera if someone has passed in from of that sensor. When the camera has a trigger, it can then relay out to a Siren or a strobe in the hopes that the intruder will go away.
D. This is the Audio In port. You can plug in a microphone and enjoy not only seeing your video, but also hearing as well. This is very important at times especially in a work environment.
E. This is the system reset button. Use this to revert back to the camera’s default settings.
F. This is the Audio Out port. Use this to set up a speaker.
G. This is the RJ45 Port. This camera can be powered through this port if you connect to a POE switch or an NVR with inboard POE ports. Video is also sent through this port, so if you power the camera via 12v DC, you still need to connect an Ethernet cable to this port and run it to your network device.
H. This is the RS485 port. There are not a lot of circumstances where you might need to use this. If you did not have an NVR and you also had a PTZ (Pan Tilt Zoom) Camera, you could control the PTZ through the Web Interface of this Bullet Camera.
I. This is a video output port. You can use this to hook up to an external monitor for viewing if you did not have an NVR. Also, you can use this port to connect to a service monitor at installation to make sure you have the correct angle, zoom and focus you require for your surveillance needs.

There are other buttons and ports that you will want to know about also:
1. This is the manual zoom dial. This camera is equipped with a 2.8-12mm manual zoom lens. 2.8mm is a spectacular wide angle view to give an overview of places such as a parking lot. If you need a closer view, use the zoom feature. A good rule is to use one fixed lens camera for the overall view and a camera with a zoom to narrow in to a specific area such as a gated entrance.
2. This is the focus dial. Use this to focus the camera after zooming into the desired view.
3. This is the Video Test port. After you install the camera and hide all those wires, you might want to zoom in or out to create a different view. Without having to run back to your monitor to see if the camera is in focus, you can use the supplied adapter, plug it into this port and then attach the other end to a service monitor. Of course you can also use our free software to view the camera from your Smart device and use that as a service monitor.
4. This is the LED Level dial. Use this to increase/decrease the LED’s to affect the IR (infrared) of the camera for night viewing. If the night view is getting washed out or if there is not enough light, then use this dial.
5. This is the OSD Cap. Make sure this is tightened to avoid water damage to the camera.
6. These 4 holes are where the supplied screws go to install the camera.

You will be impressed in the quality of the video that this 2MP Indoor/Outdoor Varifocal Bullet Security camera can deliver. There are many great uses for this camera either in a home or a commercial environment. The most important thing to remember is that an HD camera such as this could mean the difference between a
positive identity arrest versus trying to verify features through a distorted image.

With the purchase of this camera, you receive free tech support so if you ever need to know in more detail what “all those freaking wires do”, we are as close as a phone call, chat or email.

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.
