HD CCTV Camera Systems
HD CCTV Security Camera Systems provide High Definition resolution at a manageable cost. With the advent of UHD-CCTV, CCTV cameras can now produce high quality images -- including 4K UHD -- without sacrificing the low-cost and reliability. HD-CCTV camera technology has spread out among various manufacturers. There are several variations in the market (HD-TVI, HD-CVI, HD-SDI, AHD). This means that for an HD-CCTV system to work properly, both the cameras and the DVRs must share the same technology. For more information on HD-CCTV technology, please see this article.
Why Choose HD-CCTV Over IP Security Camera Systems?
HD CCTV technology is the response from conventional CCTV camera manufacturers to IP camera manufacturers. If you are used to conventional security camera systems.
Pros Of HD-CCTV Security Camera Systems:
HD CCTV systems are compatible with conventional analog CCTV cameras. If you bought cameras before 2010 or if you have coax cable (look at the cord behind the TV that goes to the cable box) in your existing security system that means you have conventional analog CCTV security cameras. If you buy HD-CCTV security system, you can upgrade your existing analog CCTV security system without sacrificing your coax infrastructure.
HD CCTV surveillance systems are more affordable compared to IP Security Camera Systems. If you are putting together a new system, you are looking for more affordable option, HD-CCTV systems are much more affordable with very similar functions. On average, same number of cameras will cost you 30% less if you buy HD-TVI systems.
Cons Of HD-CCTV Security Camera Systems:
HD CCTV technology has limited max. resolution. HD-CCTV technology has upper limit of 8 Megapixel (4K) as of 2017. IP Security Camera Systems can record and stream as high as 50 Megapixel.
Manufacturers of HD CCTV keep the borders very strict so you are not able to use a different technologines one system. For example, you are not able to take out HD-CVI camera and plug it into HD-TVI DVR.
You need to buy and install Power Supply as power source. All our HD CCTV security camera systems include "power supply" so you don't need to look any further but since we are comparing two technologoies, if you were to buy our IP Security Camera Systems, they come with PoE compliant NVRs so you can use ethernet cable to power up your IP security cameras.
CCTV security camera systems are considered by some to be the most reliable type of surveillance system. When connecting a surveillance system, there is an instant video connection to the recorder or monitor. Compared to IP cameras which have to be configured individually, CCTV cameras make installation easy because they only need to be powered and connected.
Maintaining CCTV systems is thought to be easier than an IP camera system because of the simplicity of the components. A system which shows static due to excess electricity can be easily fixed using a ground loop isolator. A video cable can be checked with a hand held spot monitor for checking connections. In a typical installation, a total of 3 wires is ran to the camera from a digital video recorder. One is for the transmission of video and the other two are for powering the camera using a positive and negative connector.
CCTV systems can be cheaper than network security camera systems. Some surveillance systems require a more demanding camera which can be controlled remotely to zoom in and move from side to side. These types of cameras, called PTZ cameras, require an additional pair of cables to control the camera. In this case, our experts might recommend a balun for your system which will let you send video, power, and data on one network cable. This is good for those looking to run a clean connection between camera and recorder. Some recorders are more advanced. Samsung’s Coaxitron recorders, for example, are able to control PTZ cameras through coaxial cable.
CCTV camera systems are used by prisons because the latency is significantly lower compared to IP systems. Gas stations use HD CCTV Camera Systems so if a customer claims they were returned an incorrect amount of change, a user can view the transaction at full speed and even slow it down. A different type of system called a hybrid system allows users to record both analog and IP cameras simultaneously. This lets users enjoy the benefits of using both systems together. Many pieces come together to form an effective security camera system. Everything from the type of connector to the type of DVR is considered when designing a system for our users. Let us help you design the right CCTV system for your application.
