Wireless IP Camera , Lens Most video-dome systems use high sensitivity color cameras that can be operated in: (1) color (2) monochrome (3) switch-over from color to monochrome automatically. The CCD cameras have an image format of 1/6 or 1/4 inch. These smaller sensor formats allow for a compact zoom lens and permit the small compact design that results in high pan/tilt speeds. Overall camera resolution is typically 480 TV lines for color and 570 TV lines for monochrome. Values of 1 lux sensitivity for color and 0.06 lux or less for monochrome are typical. Switchover from color to monochrome is automatic when the light level falls below a predetermined level. Cameras are also provided with DSP and automatic brightness control (ABC) so that the camera can view scenes containing both bright and dark areas. To capture image detail in both light and dark regions, Panasonic Inc. uses the Super Dynamic SDII technology, which records the scene at two different exposures and then electron...

There are many video devices and features that can significantly enhance the effectiveness of a  Wireless Security Camera System . These include: electronic image-splitting and compression, data annotation, picture-in-a-picture, and video scan-reversal. An electronic image-splitting device is interposed in between the camera and the monitor, VCR, DVR, or video printer. It combines parts of the scenes of two or more cameras and displays them on one monitor. The use of the image splitter increases security in several ways. (1) decreases the number of monitors (2) permits the guard to view a monitor with two or three scenes on it rather than one (3) reduces the number of recorders  required by combining several scenes onto one video signal. Image splitters do not display the entire video scene from the cameras on the screen. They only display part of each camera scene: 1/2 of the scene if it is a 2-way split, 1/3 if 3-way split, and 1/4 if 4-way split.  It is often adva...

Indoor Housings Indoor housings must protect the  Home Security Cameras  and lens from pollutants such as dust and other particulate matter, a corrosive atmosphere, and tampering or vandalism. Indoor housings are constructed of painted or anodized aluminum, painted steel, stainless steel, and several types of plastic. The material for plastic housings must be flameproof or flame-retardant, as designated by local codes and UL recommendations. The housings must have sufficient strength to protect the lens and camera, and be sturdily mounted onto a fixed wall or ceiling mount, or recessed in a wall or ceiling. The lens should view through a clear window made of safety glass or plastic. Recommended plastic window material is either high impact acrylic or polycarbonate with a mar-resistant finish. The electrical input/output access locations should be designed and positioned for easy maintenance. For easy access and servicing of internal parts, the top half of the housing shou...

The joystick is moved forward or backward, left or right corresponding to the vertical (tilt) and horizontal (pan) movements of the camera/lens unit. Likewise, the thumb trackball is moved using the thumb to initiate pan and tilt. For the disk, touch-pad, and four-button design, left and right initiate panning, and top and bottom initiate tilt. The security officer watches the video monitor and can point the  Wireless Camera  to view any area within the pan/tilt rotation range. The platform and camera move in accordance with the control signal sent by the control unit. Pan/tilt platforms are available in a wide range of sizes from lightweight, pan-only units (scanners) for indoor applications to heavy-duty, environmentally protected pan/tilts for outdoor applications. Rugged outdoor units are environmentally enclosed and intended to withstand severe conditions of temperature, precipitation, dust, humidity, and high winds. In the late 1990s the requirement for faster, more...

Many organizations believe that the Wireless Security Cameras often are not well suited to maintain the entire system because many contractors do not employ adequate IT-trained service technicians. That will change. At the same time, many IT service organizations are discovering that they can install and service IT-based security systems. Some of these organizations are rushing in to fill the void. IT-based integrated security systems must be maintained by a group that is competent in the maintenance of IT systems. That is often not the installing security contractor, whose competence is limited to the edge devices and software. I often recommend that maintenance of the IT infrastructure, operating systems, and software be placed under the authority of the organization’s IT department. Many TCP/IP-based security systems are installed without encryption or any other type of network security. I am fascinated by a security industry that does not secure its own systems. This could be...

A new architecture for alarm/access control systems begin to emerge in the near future. Unlike existing alarm/access control system architectures that wire a number of field devices from doors and alarms back to a closet where there is an alarm/access control panel, expect to see a new architecture in which each door may be served by its own individual controller, locally at the door. This has taken place. This allows for the connection of one or two card readers, door position switch, request-to-exit device, low-power door lock, one or two digital cameras, and a digital intercom (on Ethernet connections) all on the microcontroller. Digital integrated Wireless Security Camera System often interface to legacy analog systems. Legacy access card technologies present a simple challenge. TWIC cards are a good way to migrate from older cards to newer ones. Interfacing multiple access control systems requires an alarm management system that can receive signals from multiple other system...

Changing Receiver Settings After you initialize your GPS receiver for the first time, you need to change a few of the receiver’s default system settings. You only need to do this once, and a few Small GPS Tracker will prompt you to make some of these changes as part of the initialization process. These changes are mostly to customize settings based on your location and needs. Check your user manual for specific information on how to change the system settings described below. Although GPS receivers have a number of system settings that you can change, here are some of the important settings you’ll want to initially adjust: Time: Your GPS receiver gets very precise time data from atomic clocks aboard the satellites, but it’s up to you how the time will be displayed. You need to specify • Whether to use 24-hour (military time) or 12-hour (AM and PM) time • Whether Daylight Savings Time is automatically turned on and off • What your time zone is (or your offset fro...

There are several key differences between DVRs and VCRs that result in significant advantages for DVR users. The most notable difference between the DVR and VCR is the medium used for recording the video images. VCRs record images on magnetic tapes, while digital systems use HD drives, DATs or DVDs. This differentiation has significant implications in terms of the video image quality, speed of information retrieval, image transmission speed, and remote monitoring capabilities. Digital video systems using DVRs can be accessed over LAN, intranets, and the Internet. This permits security personnel to monitor remote sites across the street, town, or locations hundreds or thousands miles away. Using an Internet browser or other application software on any PC or laptop allows security with personnel or corporate management to view recorded digital video images at a secure IP (Internet protocol) address from anywhere in the world. Security systems using  Smart DVR  can play a ...

Many security consultants and security firms are hired to advise taxi companies on methods to help themselves. Situational crimeprevention measures, such as partitions between drivers and passengers, video cameras, and  GPS rearview mirror  , are possible solutions that can reduce the risk to drivers. The most recent statistics from the U.S. Bureau of Labor Statistics reported that cab drivers are ten times more likely to be killed on the job than the average worker. The use of electronic video surveillance (surveillance and security cameras and closed-circuit television (CCTV) systems) has increased rapidly in both the private security industry and law enforcement. Electronic video surveillance systems can passively record and play back video at certain intervals, be actively monitored by security personnel, or be used in a combination of these methods. Some evidence suggests that video surveillance is successful in reducing and preventing crimes and is helpful in prosecutin...

Wireless security camera systems monitor your property utilizing a closed-circuit television camera. Contrary to popular belief, these types of systems are rarely completely wireless because it is fairly inefficient to have a system that works solely on battery power. The wireless systems may utilize a wire for a power supply; however, it does not use wires for transmitting signals back to the base station. Some wireless home camera systems do run on battery power only, but most individuals find that a main power supply with a backup battery is the most affordable and reliable system to go with. Even though these systems are not always completely wireless, they are much more versatile than older completely hardwired systems that require a wire to run from the camera to the base station to transmit data. 9 Advantages of Owning a Wireless Security Camera System 1. Ensures continuous monitoring of family membes who are home alone (older children, elderly people or those who are ...

As home surveillance systems become more versatile, less expensive and wireless, they’ve become more accessible for do-it-yourself installation. Wireless surveillance ranges from a single camera for monitoring one room to larger, multi-camera systems designed as part of a comprehensive, whole-house security system. This project guide will walk you through the installation of a wireless surveillance system. Many home surveillance systems are available as a complete kit with everything you need, including wireless mini camera, a monitor, a receiver and a recording device, typically a dedicated hard drive or digital video recorder (DVR). Wireless systems can be set up for use with a professional monitoring company or may come with software that allows you to go online to monitor what your wireless home camera sees. If you plan to use a professional monitoring service, avoid compatibility issues by consulting with them before installing any equipment. Installing Wireless Securit...
