Stortech D057-650 - Analogue Camera Specification
The D057-650-S model comes with a CCD sensor which creates the ability to transport charge across the chip without any distortion. CCD will create high-quality, low-noise images where CMOS is traditionally susceptible to noise.
Primarily a transport camera, this dome can also be flush mounted and is IP67 weatherproof which means this camera can be dropped into a body of water up to a meter deep for half an hour making the D057 both an indoor and outdoor camera option.
- All D057 models come with built-in IR LEDs which make them perfect for low light environments.
- REVERSE TRIGGER CAMERA
This model uses 940nm (nanometers) Covert IR wavelengths which is perfect for covert operations as it produces zero glow and can pick up images up to 5m in distance. The 850nm D057-650-S is more effective for capturing images over a greater distance however it can be easier to spot due to the red glow on the lens.
IR Nanometers (nm)
IR wavelengths are measured in nanometers (nm) which are used to specify the wavelength of electromagnetic radiation near the visible part of the light spectrum, these wavelengths can go up to a maximum of 1050nm.
The key benefit to using a 940nm wavelength is to not produce a red glow whilst recording. This is often referred to as 'covert IR', due to the lack of visible glows emitted from the IR LEDs on the camera.
Any application where a red glow could be misinterpretted as a signal will use covert IR including undercover police work or vehicle CCTV where brake lights are present.
IP Rating - What is IP67?
IP or Ingress Protection ratings are international standard ratings to define the sealing effectiveness of electrical enclosures against dirt, moisture and foreign bodies. The first number that follows IP has a specific meaning which indicates the level of protection the equipment has to foreign bodies excluding water. The second number will identify the level of protection the product has to moisture (submersion, drips, sprays etc).
(6) Totally dust-tight. Full protection against dust and other particulates, including a vacuum seal, tested against continuous airflow.
(7) Protection against full immersion for up to 30 minutes at depths of 3 feet.
Backlight Compensation (BLC)
Backlight Compensation (BLC) technology works by reducing the dynamic range of the entire image while retaining the overall contrast. By compensating for unbalanced in a scene, the detail is restored throughout the field of view so as to provide better visibility to identify an object of interest.
2DNR Digital Noise Reduction (DNR)
Digital Noise Reduction (DNR) technology is crucial for a surveillance camera. 2DNR works by analyzing individual frames of video, identifying algorithmically and correcting those pixels that likely represent noise.
True Day/Night (TDN)
True Day/Night feature can be used for precise colour reproduction. With a built-in dual filter system, known as the Infrared Cut filter Removal (ICR) mechanism, the infrared cut filter can be used at day time, or in bright lighting conditions, to provide enhanced image in full-colour. At night time, or in harsh lighting conditions, it will be removed for greater light sensitivity in monochrome mode.
E11 Certification Vehicle Approval
The E11 Mark is the British specific Mark that covers equipment/vehicles supplied to the automotive industry. This includes commercial vehicles, construction machinery and general vehicle use and basically means the unit has been approved by ECU compliance and quality control regulations. (source)
