Alarms and Video Surveillance from Applied DigitalAs of 2010, Applied Digital is offering alarm systems and video surveillance as a core line of business. We are licensed in the Commonwealth of Virginia as a Private Security Service through the Department of Criminal Justice Services. All employees have been fingerprinted and have had extensive criminal background checks done. This protects you, the client. Alarm systems are based primarily around Honeywell sensors and control panels. They can be hard-wired, wireless, or a combination. Central station monitoring is available. Video All systems are sold on the basis of a written contract with an attached Equipment and Services Schedule and a Statement of Work. A site survey is required before a quote can be produced. Systems are tailored to the needs of your property or business. Let Applied Digital help you protect your business or property. |
surveillance systems are designed around user and site requirements. Simple, low-cost systems are available using traditional CCTV technology. Digital systems feature IP cameras wired with standard Ethernet cables and use PC-based video servers for recording and playback. Digital systems are simpler to wire, have more features, greater recording capacities, and a wide variety of cameras and image resolutions.
Alarm BasicsAlarm systems consist of sensors, a control panel, and a means of reporting alarm conditions to a central station. Sensors can be either wireless or wired. Examples of sensors that can be of either type are door/window switches and passive infra-red motion detectors. A dual technology motion sensor (microwave and passive infra-red) can only be hard-wired since power consumption is greater than a battery can supply at present. A key fob which arms and disarms a system is wireless only. Typical battery life for a wireless sensor is 3 years. Control panels provide the intelligence for an alarm system. Through panel programming, sensors are assigned to zones and a determination made for what the panel is to do when the sensor is activated. The Honeywell panels offered by Applied Digital can communicate with a central monitoring station via telephone, network connection, or a GSM cellular module in areas where the 3G network signal is strong enough. Our monitoring partner is Security Central located in Statesville, North Carolina. Their monitoring facility is state-of-the art with redundant telephone systems, uninterruptible power supplies (UPS), and diesel generators to provide backup for the facility. They have more than 200,000 subscribers across the country. They monitor subscriber systems for alarm conditions and call a pre-determined list of numbers when an alarm condition is reported. Last Updated (Tuesday, 29 March 2011 14:45) ONSSI Video Server SoftwareApplied Digital has chosen ONSSI, one of the industry leaders in network digital video recording, for a software-based solution to recording images from IP-based cameras. Three levels of products are offered depending on the number of cameras and features needed. NetDVR with its choice of client viewers including Occularis and NetGuardEVS, is an excellent choice for mid-range surveillance systems. A software video server should be a dedicated device (should not be used to run backoffice applications) and must be a minimum of a dual-core 2.6ghz processor running Windows XP or Windows Server 2008. The amount of hard disk space in the server will vary according to the number of cameras, camera resolution, and the number of days to be archived. For large numbers of cameras and days to archive, supplemental network attached storage may be necessary. |
Surveillance OfferingsThe surveillance market is divided into two segments. The first is traditional analog CCTV systems using primarily stand-alone DVRs and coax cable as the wiring medium. The second is the newer IP (internet protocol) systems where the camera image is digital from the camera to the DVR or NVR (network video recorder) and the medium is either wireless transmission or Ethernet twisted-pair wiring. Analog systems are more affordable as a rule. The basic analog camera is day color with a fixed-focus lens that is typically wide-angle. There are also cameras that are day color and night infra-red (IR). The IR illuminators are typically effective to a max of 30-45 feet. More range can be had on higher-end cameras. The higher-end analog cameras offer wide dynamic range and backlight control. They are often coupled with vari-focal lenses that have DC auto-iris for automatic exposure control. Resolution is stated in TV Lines (TVL) and often start at 320. All of Applied Digital's offerings start at 480 TVL and go up from there. Higher resolutions are necessary in being able to identify suspects. Digital cameras are more expensive, but offer sharper, clearer images than their analog counterparts. Most IP DVRs and NVRs provide for up to 10X digital zoom. Our IP camera offerings start at 640x480 pixel resolution and go up from there. Mid-range cameras have 800x600 resolution, and high-end megapixel cameras are 1280x800 or more. Both types of systems generally provide remote access via the internet that is ID and password protected. Some of the DVRs and NVRs provide for smart phone access (iPhone, Blackberry, Droid), though this access is generally restricted to live monitoring. The DVR/NVR products that we offer include the Digital Watchdog analog DVR (4, 8, and 16-channel models), Our storage options are generally 500gb or 1tb. QNAP's VioStor digital NVR (4, 8, and 16-channel models). The VioStor has different storage from 2 drive bays up. A 2-drive system has 4 tera-bytes of video storage. For higher-end IP solutions, we recommend ONSSI's NetDVR product on a Windows server platform. Remote AccessSome systems can be configured for access and remote viewing over the internet. A technician can work with you and your internet service provider to establish this capability and enable you to view and review video data from your home or on the road. Our analog and IP surveillance systems are both capable of remote access. Ask for a demonstration of remote access! Last Updated (Tuesday, 29 March 2011 14:29) |
