CCTV security cameras come highly recommended as a home and business security tool. The cameras work hand in hand with the various security systems to ensure that property and lives are safeguarded. One of the major considerations that users have to make when designing their security surveillance systems is the connectivity.

The Characteristics of CCTV Camera Connectivity


1. Wired vs Wireless

CCTV security cameras can transmit signals via either wired or wireless networks. Wired networks are preferred for most home and business CCTV applications due to the following reasons:

  • Stability: A wired network is more reliable when it comes to dataCCTV Security Cameras NYC transmission, unlike the wireless networks, which are vulnerable to radio interference and noise. 
  • Low Cost: Wired CCTV security camera systems are generally less expensive to implement, compared to wireless CCTV Systems
  • Less Maintenance Required: Wired security camera systems have a centralized power source and backup battery. Therefore, once the cameras have been installed, users don't have to keep checking them. Annual routine maintenance is sufficient to keep the cameras clean and in good working condition. Wireless Cameras on the other hand, are powered by batteries, which have to be checked and replaced regularly.

However, wireless CCTV Systems come in handy in certain applications where deploying wired networks would be cost prohibitive. For instance, it is cheaper and easier to deploy wireless CCTV security cameras in remote buildings, fence lines, and parking lots.

2. Analog vs. IP


When implementing wired networks, homeowners and businesses have two options, namely, IP and analog networks. IP networks use Cat5 and Cat 6 cabling, whereas analog CCTV networks use Coax/Siamese cabling. IP security systems are easier to implement because the IP Cameras connect directly to existing computer networks, just like any other network device.

Users that have existing analog security camera systems have the option of upgrading to the modern and more advanced IP CCTV Systems. It is possible to use analog security cameras in IP networks, by using special devices known as baluns that act as BNC - RJ45 converters. The analog video feeds have to pass through an encoder, which converts the analog video signal into digital.
