A CCTV camera is a device that is used for an effective security and surveillance system. It is used all throughout the globe to prevent any forms of illegal activity, or crimes. Captured footage can be used as a form of evidence too. CCTV cameras are an effective tool to keep track of any activity in an area. It captures a stream of videos from a camera to a TV screen for monitoring and recording. You can usually find it on trains and bus stations, malls, airport, public places and other establishments or companies. Now, it’s getting popular too among home owners for additional security in their homes. But with the range of different types and brands of CCTVs to choose from, finding the right one to buy can be a pain. Here’s what you need to know before purchasing one that will fit your need.

Some things that you should keep in mind before you purchase a security camera are the types of output it gives, the location where you plan to place it, and its controls. Knowing these will lessen the list of CCTVs to choose from.

There are two types of signal that a CCTV sends to the monitor: digital and analog. Analog CCTV relays video through coaxial cables while digital CCTV camera uses twisted pair cables to transmit the video. Most digital CCTV cameras usually have an internet protocol (IP) so that it can be networked. This is mostly used on large buildings or homes that are most likely to be targeted by burglars. You will have a large coverage of the surrounding area.

Now think where you want to place your CCTV. Do you want to put it inside your home or building, or outside? Some cameras and standard box cameras are popular for indoor use. But when you decide to place a camera outdoors, you should choose one that could stand whatever the weather is. They usually have an enclosure or covering that could protect them from snow, rain, dust, and super high or low temperature. Maybe you have seen one already like outside government offices. The most common one is called bullet CCTV camera. It is waterproof and has an infrared feature to it.

There are also some factors like minimum illumination that you need to take into account so that a CCTV can capture a video properly. How clear your output is depends on where you place your camera and how illuminated the area is. You might as well buy one that has a higher resolution. CCTV cameras and security alarms are really an effective tool to ward off potential thieves and muggers. If crime is committed in an area where there is a CCTV camera, there will be an evidence of the crime committed which will hopefully identify the perpetrator. This will keep your home safe and your neighborhood as well. So it’s better to be secure by installing one in your own home.
