Lately, the need for CCTV security surveillance systems has expanded, irrespective of the customer; CCTV technologies have proven to increase security. The systems are now very affordable. The followings are what I’ll advise you look out for when buying a CCTV security camera surveillance system:
- Number of Frames Per second (fps). First understanding what this means is that a real time second of video is 30 Frames. So a recorded second of video motion that doesn’t skip is 30 Frames. So if your CCTV camera system is capable of handling 30fsp that means you can record only one camera real time. So when looking for a good CCTV Surveillance system make sure you get a system that does 30fps for each camera. This implies that a good CCTV security camera system should be 120fps DVR capable.
- TV Lines (TVL) supported by the CCTV cameras. A CCTV camera’s quality is measured by TVL, which is the number of horizontal TV lines the camera produces, and of course the higher the lines the clearer and better the picture. The average quality is 400TVL, 420TVL is good picture quality, 480TVL is higher quality and more is even better. Keep in mind that TV Lines is what mainly controls the price of the CCTV cameras.
- Resolution of DVR display and record. Which are the original dimensions in pixels of the displayed or recorded video such as 160×120, 320×240 and 640×480 and the higher it is the better.
- HDD capacity of the CCTV DVR. This basically means the number of recorded previous days of video that the DVR will keep before recycling. Most CCTV systems by default record video based on motion which means if there is no motion there is no recording because practically it will be a still image rather than video. The average for a camera system is between 160GB and 250GB and the higher the more days of recorded video (motion) your DVR system keep.
- Remote capability. Presently standard CCTV camera systems are remote view capable. Which means you can view your cameras remotely and virtually from anywhere in the world using the internet with internet explorer or using a remote client that is installed on the PC for your access of the DVR from anywhere.
- Back up and recovery compatibility. CCTV camera systems give you the ability to back up desired video period either on CD-R, DVD-R or USB storage including USB flash drives. Making it easy to export video to other devices for many various reasons.
