With the increasing use of cameras for security and analytical purposes, it is important to know which type of camera systems offer you the most protection at the best price.
IP cameras are digital cameras that send and receive data as a computer in a network environment. These cameras are connected to the computer network by a single switch, which then connects to the Network Video Recorder (NVR). These cameras have the capability to convert analog signal into a high definition digital picture within the camera. The digital video is then broadcasted over the local area network using an Ethernet cable. In most cases, an advantage of using these cameras is that the Ethernet cable also serves as a power source.
The cameras that have this technology are POE, or Power-Over-Ethernet, making it so a single cable can serve multiple purposes. IP Cameras can be connected using switches which allow for cameras that are close to each other to be connected to a single wire. This allows for a less labor intensive setup, because a smaller amount of cable is needed to connect the cameras to the network. The security camera industry has made a shift towards this technology in recent years. The picture in the middle shows how good the picture quality can be, even when zooming in with these cameras.
A traditional analog setup, also known as CCTV, is a system of cameras and wires hooked up to a Digital Video Recorder (DVR). These type of camera systems require each individual camera to be connected to the DVR. The cameras record an analog signal which is sent back to the DVR through COAX cables. The DVR converts analog signal into a digital recording and then saves it to a hard drive. Depending on the type of DVR, Analog cameras can produce the same quality picture as an IP camera.
Originally, Analog camera systems required a much more labor intensive installation. This is because of the need for more cable to connect each individual camera to the DVR. Since these security systems are mostly found in older businesses, many of them want to upgrade their cameras. The new analog cameras have different hookups for standard and high definition. This means that you can simply upgrade the camera without having to run new wires. Businesses who have yet to upgrade their network capabilities but want better camera resolution would go this route.
Though many companies out there say otherwise, our Analog and IP systems can offer the same quality picture. Your security system needs are based solely on what system currently exists within your business, and what type of network is established. While IP security cameras come at higher cost, it is worth it to a new business in terms of the installation process. Analog cameras would be more desirable for a business that has a security system established, but wants an upgrade in resolution.
