Product Discription
Analog Security Cameras, commonly referred to as Analog CCTV Cameras, are standard definition cameras that use the composite video baseband signal (CVBS) to transmit video over a coaxial wire. Analog wired security cameras have been the industry standard since the dawn of video surveillance products because they are easy to install, are very reliable, and you don’t have to worry about them being hacked since they are usually on a closed circuit system.
most of our analog CCTV cameras have the capability to be switched between 4 different signal modes, they are also commonly referred to as 4-in-1 security cameras. By using an On Screen Display menu the camera and one of our DVRs, the cameras can be set to the desired mode. Additionally, not only can these cameras be used as part of a security camera system along with a DVR recorder, they can also be used as standalone with a BNC monitor and video quad processor to watch video from the cameras without having worries of any hacking.
Smart Infrared Light
Infrared waves fall in between what is visible to us and microwaves which are completely invisible. Infrared waves can be measured as the heat an object emits, and every object emits some level of energy, even if it is small.
An imager inside a camera allows you to capture the heat image projected by an object. Cameras with this ability are able to convert the infrared energy into electrical signals, which is then converted to an image.
Smart IR allows the camera to reduce or increase the level of infrared light it projects based upon the subject’s distance. Cameras that adjust the intensity of the camera’s infrared LEDs to compensate for the distance of an object so that the infrared does not overexpose the object. They automatically adjust the infrared light required in a scene as the subject moves closer to or further away from the camera, resulting in a clear image that is not get “washed out” by over-exposing the subject.
3D-DNR (Digital Noise Reduction)
3D-DNR stands for multidimensional digital noise reduction (DNR: Digital Noise Reduction) and was developed for shooting at night or in dimly lit places. 3D DNR is better at removing the grainy appearance that low-light video tends to take on and is far better for videos with lots of motion, as it the frame-on-frame method of comparison allows it to detect motion more accurately. As a result, it does not create motion blur in the images, and moving objects do not leave motion trails behind them
Wide Dynamic Range (WDR)
Wide dynamic range (WDR) technology balances the light on an image via image sensors (CCD & COMS) and digital signal processor (DSP). When part of an image is extremely dark but another part is so bright you can’t see any details, that’s dynamic range—the difference in lighting. Cameras with wide dynamic range (WDR) have special software that allows them to balance that lighting for one clear image. This makes them ideal for recording areas like store entrances where the contrast between the sunshine outside and the dim lighting inside can be extremely difficult to record.
Automatic Gain Control (AGC)
Automatic Gain Control (AGC) increases the signal strength of security cameras when the light level is dim, and puts a cap on it when it is bright; this keeps the output signal consistent.
In low-light conditions, security cameras use Automatic Gain Control (AGC) to artificially improve their “dynamic range” and produce usable images. AGC is basically a from of amplification where the camera will automatically boost the image received so that objects can be seen more clearly. In normal light conditions the camera will display a normal picture. However, when the light quality drops below a certain level the camera will begin to boost the signal to compensate for the lack of light.
The advantage of this technique is that your camera will produce images in much lower light conditions than standard. The downside is that the amplification is not only on the usable data in the image but also the background noise. This means that the more you amplify, the more noise you will see and the poorer the image quality will be.
