GSM ALARM SYSTEM
HSIT sms alert Gateway is designed as a cost effective remote
control system alert device. It monitors up to 8 dry contacts and 8
drivable relay outputs and 4 AD input. User-defined SMS is sent to
pre-configure mobile phone numbers when a pre-defined alarm condition
happens.These pre-configured mobile phone
numbers can belong to
technicians or engineers who are responsible in handling corresponding
alarms. With the aid of this gateway, the alarm condition brings
attention to in-charge personnel immediately. Besides it allows those
mobile phone users to trigger any relay output by using SMS. The output
can be connected with alarm indication device, such as alarm, and
others. There is a built-in microprocessor chip running on a
real-time operating system. It gives immediate response to any change in
both inputs and outputs condition. A GSM modem is embedded in the
gateway, user has to subscribe a SIM card for the gateway. The gateway
can be installed in any location under GSM coverage.

Network video recorder (NVR)
NVR is defined as network video recorder, a device for
recording digitised IP video streams, originating either from analogue
cameras connected via IP encoders and/or IP cameras where the IP video
streams are created inside each camera.
* Digital storage, usually hard disks, where the digital
IP video signals are stored ready for use.
* A database, relating the digital information to
references; time, alarms and other metadata, so that the video information
required can be retrieved and displayed quickly and easily.
* Digital to analogue conversion and replay controls.
These are usually found more in smaller, standalone NVRs and less common within
enterprise level NVRs
* An operating system, which runs the whole NVR.
* A computer network interface, which is the primary input
for IP video streams in to the NVR and also the primary way of connecting
playback equipment in large systems.

For larger sites, VideoEdge Hybrid is also completely compatible with the victor unified client.
IP Cameras
Internet protocol (IP) Cameras are quickly growing as the dominant technology in surveillance and security video monitoring devices. Unlike CCTV cameras, which generally broadcast an analog signal, IP cameras are able to send a digital signal through a computer network as well as store digital data directly on the device itself on solid-state memory. Many IP cameras also allow for two-way communication, so that the device itself can be used to communicate with users on the camera-end.
Advantages over Closed Circuit TV
IP Cameras have higher image resolution than analog counterparts, and are also easier and cheaper to install. Whether the user chooses to use the wireless features offered on many cameras, or use an Ethernet cable, the installation is still easier and cheaper than installing a CCTV camera system. Also, IP cameras can be linked to remote devices such as the iPhone and other smart phones for security monitoring on the go.
