1- The number of Frames Per second your DVR (Digital Video Recorder) is capable of handling. First understanding what that means, A real time second of video is 30 Frames. so a recorded second or video motion that doesn't skip is 30 Frames. So if your CCTV camera system is capable of handling 30fps that means you can record only one camera real time otherwise the 30fps will be divided into how many cameras they system might support. So when looking for a good CCTV Surveillance system make sure you get a system that does 30fps for each camera. so if you are looking for a 4 a good CCTV security camera system look for a 120fps DVR capable.
2- TV Lines supported by the CCTV cameras. A CCTV camera's quality is measured by TV Lines, which is the number of horizontal TV lines the camera produces, and of course the higher the clearer and better 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 camera.
3- The Resolution of which the DVR does display and record. which is the original dimensions in pixels of the displayed or recorded video Such as 160x120, 320x240 and 640x480 and the higher is the better.
4- The HDD capacity of the CCTV DVR. which 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 4 camera system is between 160GB and 250GB and the higher the more days of recorded video (motion) your DVR system keep.
5- Remote capability. Now a days a 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 using internet explorer or using a remote client that is installed on the PC your accessing the DVR from.
6- 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. for example making a copy for the police or the insurance company.
Cctv Security Camera System
Using a CCTV security camera in various places within a business has made protecting the company's assets much easier and provides the evidence usually needed for successful prosecution. Depending on the type of business and its size will determine how many cameras will be needed as well as the types of cameras in use, and installation should be supervised by someone knowledgeable in closed circuit television systems.
Most businesses will want a video of customers and others as they enter the business and a CCTV security camera with an automatic aperture will be needed if the business hopes to have a usable image. Manual aperture settings might provide a good image at night, if the aperture is open wide enough but during the day when the sun comes out, the image will be washed out and useless. Resetting the manual lens for a good shot during the day will result in a shot that is too dark at night making the individual unrecognizable.
Anywhere a CCTV security camera is placed by a door or window there the available light is likely to change significantly should be equipped with an automatic lens. All of the CCTV security cameras should also be fitted with auto-focus lenses so that no matter how far the subject is from the camera, they will remain in constant focus.
Choose CCTV Recording Device Wisely
A CCTV security camera system is only as good as the quality of the recording devices to which it is connected. For many years companies relied on videocassette time-lapse recorders to provide 24-hour recordings. While this works fine for only one camera, possible four running through a four-camera multiplexer, as the number of CCTV security cameras increase, the quality of the playback diminishes. Using digital recorders it is possible to have up to 16 cameras connected to one recorder and have good quality images available for playback.
The recorders should also allow for quick reviewing of the image to make finding specific instances easy to find. The purpose of a CCTV security camera is to use as evidence and the quicker they can be found the quicker law enforcement can proceed with doing their job.
There are different sizes available for a CCTV security camera, from a standard size about four-inches long to pinhole cameras that are mounted on a board that is about a half-inch square and no more than a quarter-inch thick. The lens can be aimed at a small hole in a wall or ceiling, hence the name pinhole and used for covert surveillance.
