HDCVI Camera Systems

HDCVI Camera Systems
Advances in technology over the past few years have transformed our lives and the world around us. Our options for leisure and entertainment as well as for our safety and security are diversifying rapidly to incorporate those advances.
In terms of security, one of the most practical and easily-applicable advances has been the development of the HDCVI surveillance camera system. HDCVI stands for High Definition Composite Video Interface.
Why install an HDCVI surveillance camera system?
The HDCVI security camera system is popular even after newer and more advanced video capture systems have been introduced. The reason for this popularity is that it strikes the perfect balance between cost, performance and ease of use.
High Quality Images and Recording
The term ‘high definition’ tells you right away that the images produced by an HDCVI system are of a superior quality. The word ‘composite’ refers to the fact that the system uses hybrid technology, in this case, one that allows you to use your existing analogue security system cables to capture and store high definition image, audio and video.
HDCVI is a popular option for homes and businesses upgrading from analogue CCTV systems because it requires minimal investment and still delivers the ability to record at 1080p.
This means that any home or business owner can capture the facial features of an intruder or the license plate number and other vehicle details of any vehicle around their compound in clear detail. Such images and video are critical in helping authorities to solve cases and, in cases where theft may have occurred, to retrieve the stolen belongings quickly.
For many homes and businesses looking for a significant boost in surveillance capability quickly and cheaply, HDCVI is the obvious answer.
If your existing analogue CCTV system uses coaxial cables, HDCVI will allow you to view and record crystal-clear high definition video from up to 500 feet without having to replace them. RG59 cables let your camera and DVR be up to 1,600 feet apart without experiencing any loss of image quality.
You can get boosters to extend the range of your HDCVI system but that is a more complicated scenario where a number of new variables come into play – it is best to consult with the team of experts at CoreApex Security to decide what the factors and their limitations are.
Simple Installation and Operation
HDCVI systems are uncomplicated in that they have a single input component (the HD camera) and a single output component (the storage DVR or video monitoring screen). This simplicity of design and execution reduces the likelihood of system and component failure, making them very reliable.
It also means that there is no lag – you can observe all activities in real time, regardless of ambient conditions, time of day and the number of cameras in the HDCVI network. There is no bottleneck to cause a delay in data transfer.
Other systems may provide extremely detailed images and a range of fancy abilities but, for the ordinary home or business owner looking for a reliable and affordable surveillance to protect their home and possessions, nothing beats HDCVI.
Setting up an HDCVI surveillance camera system
So, you have chosen an HDCVI camera or a network of HDCVI cameras. There are two other components of your surveillance network that you will also have to consider:
- Power Supply
HDCVI systems do have to have a source of power to run. Depending on the exact system installed, power may be supplied by AC, DC or both. The power supply is a critical component of the camera network. Improper power supply or that of poor quality can result in distorted images, flickering and can even damage the network hardware.
For systems of four cameras or less, the most practical option is usually a power adapter and splitter. In larger systems, it is better to use a power distribution box. In either setup, it is imperative that you choose a power supply compatible with the voltage and amperage settings recommended by the camera manufacturer.
It is also important to remember that there will be a difference in the power needs of cameras connected over a short distance and those connected over a long distance. This is the result of power loss over cable.
If your surveillance camera network has cameras connected at both near and far distances with a single power supply, it is possible that the cameras further away do not work because they do not receive enough power. Conversely, if you increase the power supply to ensure that the cameras furthest away work, this can result in a surge that will damage the internal circuitry of the cameras closer to the power supply.
The solution is to have two different power supply units for near and far cameras. You can always get an exact picture of the requirements and limitations of such a system by speaking to the friendly team of HDCVI security camera experts at GSA Systems.
It is rare that a surveillance system is set up without a DVR (digital video recorder). Most homes and businesses need a recording system so that the images that are captured on the security cameras can be used later for investigations and, if required, as evidence in a court of law.
The main factor to help you choose a DVR is its storage capacity. DVRs are very much like the hard disks of our PCs and laptops – they are able to store a limited amount of information before they are full. Some of the factors which will dictate the size of the DVR you require are:
- Recording quality – the higher the quality, the larger the disk space required
- Whether audio is recorded – audio data increases space requirements
- The duration of daily recordings – more recording hours mean faster disk space utilisation
