There is plenty of jargon in the technology world, so we’re here to explain in simple terms what a CCTV security system is. CCTV stands for closed-circuit television. This simply means that the footage collected by CCTV security cameras is not broadcasted. Instead, the video imagery or simple video is recorded onto a DVR (digital video recorder) or NVR (network video recorder).

CCTV security cameras are used primarily for surveillance purposes by retail businesses, banks, casinos, airports, gas stations, restaurants, and other institutions to protect merchandise and keep their customers safe. CCTV equipment can record video continuously or be programmed to monitor a specific event or certain time of day. The video can be stored for a period of time at various levels of quality so personnel can go back and examine old video.

Many times, the presence of CCTV security cameras in a public location is enough to deter crime. However, when a wrong is committed, the video recorded by a CCTV security system can make the difference between the perpetrator getting away and being caught.

Some of the newest security cameras are called IP, or internet protocol, cameras. These transmit digital video across data networks. Unlike strictly CCTV security cameras, the video captured by IP cameras can be transmitted across the internet publicly. Because of this, many people argue that IP cameras are not closed-circuit. However, the video can be protected by a password and kept private. This way, users can view their video privately from any internet connection across the globe—even from their 3G phones—as long as they have the password.

A wide variety of cameras are available for video surveillance purposes. The trick is finding the right CCTV security system that is right for your security application.

This is the time when Americans decide to buy a Christmas tree, pull out all the old strings of lights, put up the worn-out decorations and plug forty-seven strings of bubble lights into the single electric outlet under the picture window. Please be safe this holiday season.
According to the Consumer Product Safety Commission, each year hospital emergency rooms treat more than 8,000 people for injuries such as falls, cuts and shocks related to holiday lights, decorations and Christmas trees. In addition, Christmas trees are involved in more than 400 fires annually, resulting in personal tragedies and injuries, and an average of more than $17 million in property loss and damage.

Fire safety tips:
• Test your smoke detectors.
• Keep candles or matches away from other decorations and draperies, and out of the reach of little hands.
• Don’t overload electrical outlets.
• Replace old bulb sets with mini-lights.
• Electric space heaters are safe when used according to directions, but don’t allow furniture or decorations to sit too close. Again, be careful to not overload electrical circuits.
• Do not use candles on or near the tree.
• Dry trees and wreaths burn like a torch.
• Check all lights for frayed or damaged cords, and replace if necessary.
• Never use lights that have an empty socket.
• Turn off all holiday lights prior to leaving your home or going to bed.
• Use weatherproof outdoor lights and cords for outdoors.
