We are constantly searching the Ideal: ideal job

, perfect relationship, perfect people and solutions. CCTV is not an exception. In CCTV our challenge is to find the optimal solution, which will provide the best performance and reliability.

Outdoor camera is a special type of camera, which should not only generate clear images of the monitoring area, but also ensure smooth operation in all weather conditions.

To make the right choice, let's discuss some basic characteristics that are necessary to pay special attention.

1. Presence of quality CCD. Sony Super HAD II CCD can provide outdoor camera operation at up to 0.15 lux in Color and up to 0.001 lux in B/W modes (IR illumination off). Due to the featured DSP processor outdoor camera supports digital noise reduction (SSNR III) that improves image quality in low light conditions.

2. High quality images with 600/700 TVL resolution in Color and B/W modes. For ensuring the highest possible degree of image detail, outdoor camera should generate high-resolution images with 600/700 TVL resolution in Color and B/W modes respectively. To prevent sporadic switching between Color and B/W modes, outdoor camera must be able to adjust delay time for Day/Night switching - from 5 to 60 seconds. it will be very helpful if camera allows installer to configure camera switching between Day and Night modes.

3. IR illumination. It ensures camera operation in low light conditions. In case of lighting absence outdoor camera can activate IR LEDs that provides clear observation of the monitoring area. When monitoring close objects installer can avoid "smearing" effect by adjusting the power of IR illumination.

4. Functions for improving image quality. Digital image stabilization (DIS) is used to eliminate image flicker, resulting from gusts of wind or other sources of vibrations. Due to the high light compensation (HLC) of the bright image areas, the adjacent areas of the image can be viewed more clearly. High dynamic range (SSDR) function enables installer to utilize outdoor camera on the applications with contrast lighting, suppressing extremely bright image areas and adding contrast to the image areas with a low light.

5. Detection areas and private zones. Among useful features of the functional outdoor camera should be mentioned the ability to specify up to 8 motion detection areas with adjustable parameters (size, position, sensitivity). In addition, outdoor camera can configure up to 12 private masking zones on the image to block its view by the operator.

6. Easy installation and use.

Of course, all these characteristics are not comprehensive, but we are sure that they will help customer to make the right choice.
