POE Problems in CCTV installations

when deploying POE based CCTV cameras many installers overlook some key power problems related to basic POE switches. 4k UHD cameras are no exception and in many cases require additional power. Standard POE switchs will not do when paired with high consumption cameras that have built an infrared illumination, motorized lenses, or pan tilt capabilities.

There are many high-power POE switch options available in the market today. With basic model starting at 7 to 8 W per channel and going up to 25 Watts ( IEEE 802.3at) and beyond as power supply distribution technology improves. Obviously high-power means more expense so make sure to quote accurately to avoid problems in the future.

Eight megapixel video also produce massive conflicts on standard networks. Make sure to read our articles on managing data and creating the correct infrastructure for these resource hogs.

4K surveillance can be managed properly and deployed correctly to provide your customers with unprecedented detail.

Quality questions on UHD CCTV

The most common question heard today by security professionals has to be “what is the best resolution available?”

This is a very difficult question to answer based on the fact that budgetary concerns are a massive limitation for most applications.

However, for those that have unlimited budgets there are many levels of ultra megapixel cameras available, Even some going beyond the 20 megapixel range.

For UHD 4K systems, we return to the same limitations as legacy analog or IP. Many levels of quality exist within the 4K resolution arena. There are cameras available on the market for under $400 which are rated at 4K (8 megapixel) yet some of the nicest ones we’ve seen are well over $1000 each. So what makes the difference? The answer could be something as simple as the lens. Much like camera prices, there are many levels of quality and prices for lenses that are rated UHD. Once again we have seen prices ranging from $50 up to $600 for a single fixed lens. Like everything else in life, you get what you pay for. Eve true 4K resolution is what you desire, be prepared to shell out a substantial amount of money to get real 4kcctv.
