What is the focal length 2?
The focal length 2 is a measurement that refers to the distance between the lens and the image sensor when the lens is focused at infinity. It is a key parameter in determining the field of view and magnification of a lens. A shorter focal length 2 results in a wider field of view and greater depth of field, while a longer focal length 2 provides a narrower field of view and higher magnification. **
-
Which focal length do I need?
The focal length you need depends on the type of photography you are interested in. For portraits and close-up shots, a focal length between 50mm to 85mm is ideal. For landscapes and architecture, a wider focal length such as 24mm to 35mm is recommended. If you are looking for a versatile option, a zoom lens with a focal length range of 24-70mm or 70-200mm can cover a wide range of shooting scenarios. Ultimately, it is important to consider your shooting style and preferences when choosing the right focal length for your needs. **

HiLook PTZ-N2D400M-DE/14(2.8/8mm TandemVu 4MP+4MP Fixed Lens POE PT CameraThe HiLook PTZ-N2D400M-DE/14 is a PTZ camera that incorporates both a wide-angle bullet camera and a powerful PTZ camera to offer the best of both worlds and cover a much larger area than a conventional camera. This exciting new type of camera provides wide view and small details at the same time. The overall view remains even during the pan, tilt, and zoom manoeuvres, so that users will see everything and not miss any detail. The PTZ-N2D400M-DE/14 features human detection and auto-tracking, as well as smart hybrid light that provides full colour imaging, even in complete darkness. 2-way audio is available through the integrated microphone and speaker, and video files can either be saved to a hard drive in an NVR, to an SD card up to 512GB, or to the Hik-Connect cloud service. Hikvision Cloud Storage Cloud-based solutions have quickly come into focus in many industries, and video security is no exception. Video Security as a Service, or VSaaS, is the technology that hosts the hardware and software of video-based security systems in the cloud, so that users can access their IP cameras anywhere they might be through any device and have video footage at their fingertips. Since there is no hassle of on-site server installation and system configuration, VSaaS is an ideal choice for small- and medium-sized businesses (SMB). It is more cost-effective than traditional video security solutions since users can spread costs out over the contract term and pay only for the services that are actually used. Hikvision’s VSaaS makes it possible that disparate devices interact with each other as a convergent system. This enables them to perform specific tasks according to pre-defined linkage rules, for example, an intrusion event detected by the alarm system could trigger push-notice with video footage, and simultaneously close specific doors, as well as sound the siren. Features: High quality imaging with 4 MP resolution Support Human Detection and Auto-tracking Lite Smart Hybrid Light: advanced technology with long range Hik-Connect cloud service and app for remote management and views of devices Built-in microphone and speaker for real-time audio security Built-in memory card slot, support microSD/SDHC/SDXC card, up to 512 GB Water and dust resistant IP66161,49 £*Shipping: 0,00 £Secure redirect to the provider

HiLook IPC-D140HA(2.8mm) 4MP MD 2.0 Fixed Dome Network CameraThe HiLook IPC-D140HA is a 4MP IP turret camera with a 2.8mm fixed lens and smart Motion 2.0 human and vehicle detection. It features efficient H.265+ compression technology and PoE (Power over Ethernet) which allows both data and power to be sent over a single ethernet cable, making installation quicker and easier. DWDR (Digital Wide Dynamic Range) provides clear imaging in strongly backlit conditions and an IP67 rating against dust and water ingress makes it ideal for outdoor use. In addition, the IPC-T250H-MU also features Infrared sensors that provide clear imaging in complete darkness, up to 30 metres. Please note: When installing any HiLook dome camera, please be aware that it's 2 axis adjustment only allows for installation horizontally on a ceiling or fascia. If wall mounting is required, we suggest purchasing the pendant style wall mount bracket. We recommend that dome style cameras are always mounted horizontally to minimise sun glare, and also rain droplets running down the bubble and obstructing the cameras view particularly at night when the infrared is active. Motion Detection 2.0 Hikvision has upgraded its Motion Detection with its AcuSense technology. This takes motion detection to the next level with features that distinguish human beings and vehicles from other objects in any given environment, and tools that make video searches as smart and quick as possible. The first key way that Hikvision Motion Detection 2.0 improves security is by allowing users to easily configure alerts when people or vehicles enter an environment. If an area is usually busy with visitors or pedestrians, the systems can be configured to ignore certain areas of the screen and only generate alerts if a person or vehicle enters an unauthorized zone, for example. With automated alerts for vehicles or people entering restricted areas, security teams can respond much more quickly and effectively to potential security breaches – helping to increase protection for people and assets. The second major advantage of Motion Detection 2.0 is the ability to search video footage based on the appearances of people or vehicles during a specific period of time. Users can call up and playback video clips of people and vehicles that have been recorded on back-end devices like NVRs or DVRs, with no need to pore over hours of video footage. This feature means that hours or even days of security footage can be reviewed in just a few minutes and that teams can quickly find high-quality video images of critical security breaches that have occurred. DORI - Recommended operational range of the camera DORI is a standardized system that provides a clear framework for evaluating the effectiveness of CCTV cameras. It is based on the European standard EN 62676-4, which defines specific criteria for detecting, observing, recognizing, and identifying objects or individuals within a camera's field of view.
