Choosing different surveillance systems requires research before deciding. Most video surveillance systems are available, but some are more versatile than others. For example, IP cameras transmit images directly to your local network. On the other hand, analog cameras are less versatile and are more expensive. Ultimately, the decision depends on the size of your business and your budget.
NVR Systems Are Easier To Install Than DVR Systems
When identifying how to choose a video surveillance system for your business, NVR systems are cheaper and can be more flexible and future-proof than DVR systems. NVR systems offer better image quality, broader functionality, and more flexible installation. They also tend to be easier to install than DVR systems. While DVR systems require coaxial cable installed, NVRs are wireless and can be wired through Cat5e or Cat6a cable. If your current security system uses coaxial cable, you may want to go with a DVR. Otherwise, NVRs are more convenient if you already have a security system. The disadvantage of DVRs is that they tend to be more expensive.
IP Cameras Transmit Images Directly To A Local Network
The IP cameras send images directly to the network rather than relying on a local network. While they can work in a local network, most IP cameras are connected to the network through a wired Ethernet cable. This is the most reliable IP camera connection and has a lower risk of signal interruption and interference. In addition, this method has practically no chance of unauthorized access.
The IP camera has many advantages, including fast and convenient image transfer. When wireless, IP cameras can record internal video footage for significantly less time than their wired counterparts. As an added benefit, they also allow for easy sharing of material by email or SMS. A video surveillance system is incomplete without Artificial Intelligence, so IP cameras offer this technology. Some IP cameras can even integrate software programs to perform facial recognition, database matching, vehicle counting, and crowd counting.
DVR Systems Are Less Versatile
DVR systems are a low-cost alternative to IP video surveillance. While their capacities are limited, DVRs are helpful for home and small business use. These systems utilize analog cameras that stream a raw video signal to the recorder. Since analog cameras do not have an Internet connection, they must be powered by an external power source or coaxial cable. Coaxial cables are more expensive than Ethernet cables, but they allow the mixing and matching of different brands of cameras.
DVR systems are also less flexible than NVR systems, which rely on AD encoders to process video data. The downside is that DVR systems do not support wireless cameras. Additionally, if you plan to use more than three cameras in a single system, you must purchase additional coaxial cables for each camera.
Analog Cameras Are More Expensive Than IP Cameras
In general, IP cameras cost more than analog cameras. The files captured by these cameras are larger. As a result, many businesses choose analog cameras. However, an analog camera may not meet all your needs. Nevertheless, an analog camera can extend the system’s life and satisfy your needs.
The disadvantage of analog cameras is their low frame rate. This makes them inefficient for places where motion is frequent, and details must be precise. IP cameras can be installed with just one network connection.
NVR Systems Are More Susceptible To Hacking
One of the most recent examples of a hacking vulnerability in NVR systems is the Annke N48PBB network video recorder. Designed for monitoring live video streams, the NVR allows users to watch recorded videos and manage cameras. However, researchers from Nozomi discovered a vulnerability in this NVR that can allow attackers to view recorded video and shut down cameras. These vulnerabilities have been around for years, but this one is difficult.
Another significant vulnerability of an NVR system is the vulnerability of the system. The security of these systems is significantly more at risk than their analog counterparts. These NVRs can send and receive audio streams over a network. They are often connected to the internet. The security risks of such a setup include exposing private data and enabling unauthorized access to the footage. However, security experts say that the benefits of NVRs outweigh their risks.
