Upgrade your analog video surveillance system for better image quality. What you should consider.
Many people decide to upgrade their systems to improve the overall picture quality. The first thing a lot of people ask themselves before making this improvement is this: will I have to redo my entire system, or can I replace some parts only?
HD camera cables.
The first thing you need to check is your cables. Some cables can transmit analog and HD signals; However, some cheaper options are only analog. In addition, some cables may require modification of their maximum length or their connectors. When upgrading to 1080p BNC cameras, if you have previously used an RG59 or RG6 coaxial cable, you can use the same cable to transmit video from HD cameras.
This includes all types of AHD, HD-TVI, HD-CVI and HD-SDI cameras. A special consideration is to do with HD-SDI cameras, it is that the distance is generally limited to 80 m (AHD, HD-TVI and HD-CVI are able to pass an RG59 cable at the same distance for signals HD and analog). An HD video amplifier on coaxial cable can also be used if you need to use the cable over longer distances. These devices also allow the use of AHD, HD-TVI and HD-CVI cameras.
Power supplies for cameras / power supply boxes.
Next, you need to examine your power supply. Similar to analog, HD cameras use 12V DC or 24V AC power. Therefore, if you already have 12V DC, buy HD cameras that also work in 12V DC, and vice versa.
Image recorders.
A hybrid DVR can be used to connect analog and HD security cameras. This allows users to use both standard definition and high definition cameras on a DVR. Hybrid DVRs also allow the user to switch to HD faster. However, an upgrade will be required if you do not have a hybrid DVR system.
Security cameras. Now you need to determine whether or not you want to replace your existing SD cameras or add to the HD ones. If you add them to your system, you will need to make sure that you have a hybrid DVR capable of operating both types of cameras.
Coaxial HD cameras. A final aspect to consider is the use of a selectable 4-in-1 coaxial HD camera. These are extremely flexible to install as they support four video models (typically: CCTV, AHD, HD-TVI and HD-CVI). These can be used with just about any DVR and many have a joystick to select the video mode. This is another great option for customers wishing to upgrade in the future, as it provides a simplified path to do so.
Do not buy a video surveillance system before reading this article!
Buying a complete system can save you a lot of effort as it is designed to work in one piece. These systems are generally of good quality and may cost less due to the overall supply, but some prepackaged systems may not meet certain needs. Analyzing its components can allow the user to adapt it to his specific needs. It also allows you not to buy things you don't need.
Cameras.
The first thing you will decide is the type of camera you want. Your main options are analog, analog HD or IP (network). Analog cameras will require cabling for power and video signal transmission. IP cameras send the video signal over the Internet and therefore do not require the second cable. Although some IP cameras come with an internal battery, most still use a continuously powered cable for greater reliability.
You will also need to choose a camera style. For this, you need to consider its purpose and location. The most common camera styles are "tube", "bullet", dome and turret. These also come with different types of lenses: fixed, the main things to consider are the level of discretion you want, the area you are trying to film and the degree of control over the image you get.
The image recorder.
Then you need to choose a video recording device. If you have decided that IP cameras are the best choice, you need a network video recorder (NVR); if you selected analog, you will need some form of digital video recorder (DVR). The key here is to get the right one, if you want to use HD video cameras, you will need a hybrid DVR. A hybrid DVR would also be useful if you choose an analog SD card first, but may want to upgrade later. This would allow you to use all of your cameras on the same DVR. You will also want to verify that the recorder can support the number of cameras you want to use, or possibly add more later.
Complete video surveillance system
If you cannot choose a camera type, you can use a HD TVI DVR. This allows the three types of cameras to be used via a single video recorder. An HD TVI DVR converts the video stream into digital files allowing connection to IP cameras via a CAT5e cable. A final consideration is the additional hard drive storage. This becomes all the more crucial as your number of cameras increases, as the amount of stored footage also increases.
Cables / Connectors.
Now you need to choose the correct cables and connectors for your cameras and video recording device. It is important to note that you do not have to rush this step, buy good quality cables and connectors to ensure the proper functioning of your system. There is nothing worse than investing in a high-end system, but putting in place inexpensive cables that reduce its quality.
If you choose analog HD, you will probably need coaxial cables to transmit your video signal directly to the DVR. If you chose IP, you will probably need a CAT5e cable. You will also need to find the appropriate cable to connect to your power supply. It is important to note that you will also need to find the right connectors to adapt the cables to your system. This information will depend on your previous selections. Just make sure they match so everything fits together.
The power supplies.
Finally, you will need a power system to operate all of your devices. The two most common options are 12V DC and 24V AC. You will need to make sure that they match your video recording device and your cameras. You may also need batteries for some of the IP cameras that support them.
The advantages of PTZ security cameras with a 360-degree view.
