Any CCTV security camera can help prevent crime and increase the probability that police will arrest offenders. However, some of these devices perform much better than others. Be sure to carefully compare analog and IP models before you install or upgrade your equipment.
IP vs Analog Camera Systems: What Are they?
Both technologies use similar image sensors, but they differ in most other ways. An IP unit digitally transmits video through a standard local area network. The data quickly reaches a network video recorder; this device stores the latest footage.
On the other hand, analog CCTV systems use separate coaxial wiring to transmit images. A digital video recorder saves data for future access. The DVR receives analog footage, yet it records video digitally instead of using magnetic tapes.
How do IP and Analogue Differ?
One major difference between analogue and IP cameras involves their ability to resist interference. If electrical equipment or machines produce noise at the wrong frequencies, analog video may become distorted. Interference normally won’t affect a LAN-based digital system.
Technicians need different skills, equipment and supplies to set up each type of security camera. Conventional units often necessitate bigger wiring projects, and IP cameras demand installers with computer networking expertise.
These systems also have different requirements after setup. A digital camera’s high-definition footage takes up more space than conventional video, so you might need to upgrade your storage media. Analog models demand more cable maintenance and interference troubleshooting.
The initial expense of digital surveillance technology has dropped significantly in recent years. This camera equipment still costs more than the alternative, but it can monitor a much larger area. Consequently, analog cameras only provide a more affordable option if you want to secure a relatively small property.
Advantages of IP Cameras Over Analog
Ease of Installation
A digital system can offer impressive benefits. For instance, it transmits video footage over the same LAN wiring that computers, printers, and routers use. Most cameras run on electricity from these cables, so there’s no need to install separate data or power cords. This makes installation fast and easy.
Many IP units have remarkable capabilities. A sophisticated camera could notify you or sound an alarm when motion occurs in a predefined area. They can also detect smoke, track specific colors, count the number of people that pass by, and more. It’s also possible to view live footage on a remote device. You can even adjust the zoom level remotely.
Both analog and digital models provide better picture quality than they did in the past. Nonetheless, the best IP units offer twice the resolution of high-end analog cameras. They also record at higher frame rates. These advantages make it easier to recognize faces and license plates.
IP security cameras may still cost more in certain situations, but they offer numerous advantages involving image quality, remote access, and interference prevention. They clearly represent the future of CCTV. To find out more about the using IP CCTV for your business, contact TC Tech Systems today.
