Today there are a lot of options when it comes to choosing a quality CCTV security system. You may decide to go with a traditional analog system, HD-SDI, HD-CVI or even an IP network based security products.
One thing all of these options have in common is you will probably have to run some sort wire to the cameras. Yes, there are some “Wireless Security Camera” solutions available on the market today, but if you do some research you will find that there are a lot of limitations to wireless security cameras. Most CCTV professionals would probably not recommend a wireless system in an environment where up-time and security are critical.
I do want to mention that it is possible to reliably transmit video wirelessly using a device such as the TP-LocoM5 – Wireless Access Point/Bridge as seen here at www.securitycameraking.com.
But even then you would still need to have a power wire run to the camera or a local power source near the camera and it only works with IP Cameras.
That being said, we will be talking about a fully-wired system in conjunction with a storage device such as a DVR (Digital Video Recorder) or NVR (Network Video Recorder).
