Too often, when we turn on our TV, we find another newscast about a murder or a robbery in a public company. Most of the time the offender is able to hit the streets and cause more problems, before being captured. Many entrepreneurs are investing time and money in a monitoring system that can not grasp the situation, a high quality enough to be useful to the investigation. In this article I will discuss some of the key factors that will help both the victim and can shareLaw enforcement to increase the chances of arrest of a suspect.
Recording quality begins with the DVR
The brain behind every safety system is the digital video recorder. The importance of a great unity is a necessity and often the end users a low-cost tape recorder to expect high-end results to capture. The price is not always a factor in the purchase of a DVR quality, but can sometimes mean cheap, cheap. One thing I would point out to my customers always start with the purchase of a DVRwith the FPS (frames per second). For example, an 8-channel DVR, 60 FPS, which has a lower quality than 8-channel DVR with 240 FPS playback. A good rule is to add the number of cameras and divide the sum by the total number of frames per second, offered by the DVR. The goal is a minimum of 30 frames per second for each camera in the security system. Please note that high-resolution cameras, megapixel cameras, some channels will result in a lower frame rate than any other record.
WhenCooperation with law enforcement, you should be able to quickly get your shots, while having the ability to back up your data. Recorders that are equipped with DVD recorders are still a good choice. Note that you have a recorder that has a watermark on the recorded file in order to get permission for the video in court. Two well-known manufacturers, GeoVision and Avermedia offer this feature.
Camera Strategy
It 's always important, the best camera for their complianceApplication. Camera position, lighting, the detail of the images and should play an important role in the selection. Looking at the layout of the scene you want to look at the camera position. If this camera would be in a corner? We also want to look at the backlight in conjunction with the camera angle. There are obstacles that could shelves or lamps? Ultimately, you should get the best view to capture a clear facial featuresshot. Lighting plays an important role in the choice of camera. This is due to the fact that the light directly, without auto-iris can cause too much noise to get a picture. The camera can capture pictures at night? They will find the camera in low light or no light environments? In this case, the AP-148z would be a suitable choice for the application.
The image quality is what you after, if you try to be to get the details. This will be purchased directly affected by the recorder. IPCameras have the ability, picture quality, which is always an option, if combined with an NVR (Network Video Recorder) or a PC-based DVR. However, if the preference is analog, then evaluate the chipset of the surveillance camera have been considering. A 1 / 3 CCD is suitable for most situations. CMOS chips usually have an image quality inferior to that of HAD. Another factor to note the TVL (TV lines). TVL top means you can enjoy a better quality picture from yourSecurity films.
