Security Technologies
Before purchasing any piece of surveillance equipment do your research and become an informed consumer. The surveillance equipment market is highly competitive with many products available from hundreds of vendors. 1st Choice Security Technologies is at the forefront of video surveillance technology in Northeast, PA. From what I have seen here in Northeastern, PA is that many security dealers are selling low-end CCTV cameras that will not produce acceptable results in image quality or dependability. The huge variety of CCTV security cameras and video surveillance recording systems can be a huge advantage for the consumer, but it can also present an overwhelming number of confusing choices! The confusion is what is leading to dealers in the Scranton, Wilkes Barre area getting away with selling low quality systems. Become informed about CCTV, video surveillance.

IP cameras offer flexible installation, ease of use, higher-quality images, stability, and scalability as new cameras can be added to the network at any time.
CCD chip: A CCD image sensor is a light-sensitive image device available in many IP network cameras. The sensor transforms light into electronic signals. CCD sensors provide strong light sensitivity allowing for video surveillance in low-light conditions.
PTZ: PTZ (pan/tilt/zoom functionality) is a feature available in many IP camera models. PTZ allows users to monitor large areas with a single network camera. Pan, tilt, and zoom functions can be controlled remotely so operators can follow activity and focus in on specific details.
CCTV: In its truest form, a CCTV (or closed-circuit television) camera is an analog video camera. The camera transmits signals via coaxial or CAT5 cable to a single central location for monitoring, recording, and video analysis. While the recent trend is a push towards IP network cameras, CCTV cameras are still widely used, and offer a cost-effective answer to many common surveillance scenarios.
CCTV technology has been around since the 1940's, and became a major player in the security industry around 1970. The technology is tried and true, and there are CCTV camera models for virtually any surveillance application. The two main categories of CCTV cameras are fixed cameras and pan/tilt/zoom models which can rotate horizontally and vertically to cover more area.
Resolution: Resolution is the measure of how much detail an image can hold. The higher the resolution the more detailed the images are. In the case of IP cameras, resolution is usually specified by pixel-count. Although some camera dealers refer to 420TVL as high resolution, most manufacturers start at 420TVL and go up to 540TVL and even 600TVL.
There are also mega pixel cameras that are measured in megabytes of pixels and offer an incredibly sharp image that can be zoomed in for small details. These cameras are somewhat expensive but can eliminate the need for multiple cameras.
TVL Resolution: The image detail of an analog CCTV camera is usually conveyed in a form of measurement called TVL (or TV Lines). Think of the video picture as being composed of active horizontal lines. These lines are delivered to a monitor or recording device in two off-set fields. One field contains even-numbered lines while the other contains odd-numbered lines. The viewer sees a complete picture because the lines are interlaced. Since the picture has a 3x4 aspect ratio, the amount of detail you can measure in 3/4 of the picture's width determines the horizontal TVL resolution. Generally, most standard CCTV cameras offer a TVL resolution of around 380, while high-resolution cameras will deliver something closer to 540 TVL.
DVR or Digital Video Recorder: A Digital Video Recorder (DVR) contains software, video storage, and a computer hard disk all in a single unit. The DVR accepts analog video feeds and converts them to digital. It's a cost-effective way to bring an analog CCTV system into the modern world, and provides some of the same benefits as IP video, but in a more budget-friendly solution.
