Every online ups needs to be serviced every 6 months to ensure its proper operation and battery condition. We are proud of our reputation for customer service We have a range of maintenance plans to suit every customer requirements from simpler repair to annual service contracts with guaranteed response time. And every customer of Mercury has free access to our customer support.

Online ups needs to be installed under supervision of a qualified technician. Your supplier of Mercury Online ups can install it for you. Mercury also provides necessary assistance to your electrical contractor. Note: Never Try to install the online ups yourself because it has some necessory steps which you dont know and this is a hi-risk job because of lack of technical information due to very high DC voltage (battery), By doing so the warrantee also void.

Online ups provides better overall power protection to your computers and peripherals. This protection includes power conditioning, regulated voltage and frequency and zero transfer time to battery during mains failure.

To satisfy the requirements of various applications and from the view point of criticality in operation, different topologies are employed in Online ups. The complexity and sophestication increases in ascending order. Hotstandby online ups configuration: This configuration comprises of two units of online ups (named online ups1 & online online ups2). When online ups1 is delivering power to the load, online ups2 remains idle. In case of failure in the inverter of online ups1, static switch is enabled thereby providing uninterrupted power to the load through online ups2. online ups1 runs in synchronism with online ups2, ensuring no break transfer from online ups1 to online ups2. Under healthy conditions, the batteries get charged through their corresponding rectifiers. Parallel redundant online ups configuration:

Truth Table:
b		Static Switch		Result
Online ups 1 & 2 healthy		OFF		Load is shared in equal propotion (50%) by both online ups.
Online ups 1 healthy & online ups2 trip		OFF		online ups1 handles entire load
Online ups 2 healthy & online ups1 trip		OFF		online ups2 handles entire load
Online ups 1 & 2 trip		ON		Load works on Bypass

Critical non-critical system of online ups Online ups 1 & online ups 2 deliver power to the critical & non-critical loads respectively under healthy conditions. online ups 1 synchronizes with online ups 2 & online ups 2 synchronizes with the bypass. In case of a critical inverter failure, critical load works on online ups 2 through enabled STSW1, simultaneously transferring the non-critical load to Bypass by activating STSW3 & inhibiting STSW2. The restoration of the critical inverter will be responsible for retransferring the loads of their corresponding inverters. The batteries are charged through their corresponding rectifiers.

Truth Table of Online ups :
b		STSW1		STSW2	STSW3	Result
online ups 1 & online ups 2 healthy		OFF		ON	OFF	Critical load on online ups 1 Non Critical load on online ups 2
online ups .1 trip & online ups 2 healthy		ON		OFF	ON	Critical load on online ups 2 Non Critical load on Bypass
online ups .2 trip & online ups 1 healthy		OFF		OFF	ON	online ups 2 handles entire load

IP stands for Ingress Protection An IP number is used to specify the environmental protection of enclosures around electronic equipment. These ratings are determined by specific tests. The IP number is composed of two numbers, the first referring to the protection against solid objects and the second against liquids. The higher the number, the better the protection. In IP66 First Number 6 - Totally protected against dust Second Number 6 - Protected against low pressure jets of water, limited ingress permitted (e.g. ship deck) In IP67 First Number 6 - Totally protected against dust Second Number 7 - Protected against the effect of immersion between 15cm and 1m

2 users for now because of limitation of bandwidth of network.

IP cameras provide two RJ-45 connectors. One is WAN and one is LAN. Both of them are 10/100. The difference between a WAN and a LAN is that WAN is to be connected to the internet, while LAN is to be connected to a local network. Since the internets bandwidth is very critical, we provides hardware QoS (Quality of Service) on the WAN port to ensure the bandwidth when uploading video streams through the internet.

If an IP camera can support DDNS (Dynamic Domain Name Server), users can set the IP camera at a virtual domain name (such as cam8.security.HongKong.xxx.xxx) at dynamic IP, and is able to view this IP camera anywhere that has access to the internet.

Wireless products are available now. we will launch 2 or 3 new models quarterly.

No. The camera works fine also in local network without the internet connection. If the remote users are in the same local network, its not necessary to connect the IP cameras to the internet.

Yes. You can record the video at remote or local by using the software provided by the IP camera manufacturer. Network Attached Storage (NAS) is a very useful tool in video storage, and it is easy to install.

It depends on both the resolution and frame rate. Below are three of the most popular compression technologies and their required bandwidth and some of other important information. Compression Protocol: M-JPEG/ MPEG-2/ MPEG-4 Compression Rate: 6; 30-40; 200-500 Resolution: 352 x 288; 720 x 576; 720 x 576 Frame Per Second: 25-30fps; 50-60fps; 25-30fps Bandwidth Required: 1.5Mbps: 4-15Mbps: 10K-1Mbps Also, please note that 30fps/ 25fps (NTSC/ PAL) is the required frame rate to provide continuous motion and good quality (DVD like) video.

A web camera is connected to a PC, normally through USB, and uses the PC to make video available to other viewers. It will not work without a PC locally connected to the camera. An IP camera usually stands alone, and combines the functionality of a high-end web camera, the PC and network interface into one network-ready product.

Make sure that the RTSP port of the device is set to 2000 plus the HTTP Port number. For example, if the HTTP port is 88, then the RTSP port of the device that you configured on GSurf / mobile phone should be 2088.

DDNS is an acronym for Dynamic Domain Name Service. It is important to choose an IP network camera that has DDNS support for dynamic IP addresses. Chances are that the network has a dynamic IP address (which changes with every log on). DDNS also allows for a website to be linked to the IP camera that is constantly updated with the correct information and has a reliable feed.

Please check whether the IE add-on is installed correctly. Once you log into the GXV3501/ 3504 / 3601s web interface Internet Explorer will indicate that This website wants to install to following add-on: Triplex Pro-4 ViewerSetup.exe.

The features to look for in a network camera are MPEG4 compression, quality of construction, resolution, frames per second (fps), chip type, cost, and availability and quality of the software.

IP cameras or network ip cameras stream live video via digital packets across an internet protocol network such as a LAN (Local Area Network) or the Internet.

IP Video Surveillance is the transmission of video that utilizes open internet protocols and standards for the purpose of recording and monitoring clips.

Many systems referred to as PTZ are actually the combination of a pan - tilt housing with the addition of zoom camera.

Variable focus (or varifocal) lens cameras allow the user to modify the field of view from its widest/ most panoramic to the narrowest and most telephoto views. we have an incredible weatherproof integrated PTZ camera available (DN-PTZ) which allows you to facilitate pan, tilt and zoom functions all from a SINGLE control- with all parts protected inside a weatherproof dome with thermostat controlled heater/ blower inside!

Remotely viewing one or many cameras over is not a huge challenge. However, remotely controlling functions of specialized camera is where it can get tricky. The problems are generally the result of incompatible equipment. If the internal software protocols of the site driver are not recognizable to the camera- or vice versa- the result will be a functional camera with no ability to function. This is a strong warning of why it is necessary to do your homework before designing or purchasing any type of complex equipment. Again, as with most things- there are a wide variety of products out there to suit a variety of needs. Please contact us for specific or advanced PTZ issues.
