Preferring quality, Multi Alarm Co. intends to fulfill customer requests. Almost all orders have to complete individual requests, so there is a large scale of possible devices to fulfill orders.
With regard to the circumstances mentioned above our company offers
B&W and colored picture cameras for in-site and off-site purpose, further real night security cameras manufactured with infra reflectors. Beside of “normal function”-cameras Multi Alrm offers also Dom cameras and speed Dom cameras with fixed or removable optics.
Please find below some of the products provided by diverse manufacturers and offered by Multi Alarm Co.: Everfocus, Sunell, Acti, Vivotek, IndigoVision, Axis, Rekeen, Samsung, Avemia. If a given task requires other methods or devices, products of other manufacturers can be also purchased and installed. Beside of cameras Multi Aarm Co. trades and offers a large scale of video storage systems, too.
Before the mounting and installation of video surveillance system Multi Alarm’s experts will survey the physical environment of the being video system, and depending on the results of the survey, customer can choose a proposed kind of video monitoring system consisting of individual items.
Multi Alarm Co. offers also video surveillance kits for smaller and not complicated area consisting maximal of 4 cameras. These compact kits can be offered by a reduced rate.
There is a large scale of video surveillance systems to be mounted and installed. The scale starts at simple corridor watching and ends at entire public area surveillance systems of a town. Not regarding here the size of the items, there are basically 4 technical solutions for their installation, depending on difficulty of the installation and on the kind of the order.
- Analog video systems with multiplex storage mechanism
- Analog video systems (CCTV) with digital storage mechanism
- HD CCTV video systems
- Video systems based on IP-cameras
Analog video systems with multiplex recording mechanism: This is one of the technologies which have already begun to date, but due to their good pricing they are expected to have an important ranger on the market for a longer time. Perhaps for this reason, development of this kind of systems doesn’t end, manufacturers offer every day cameras with 620 or 700 TV-rows.
Analog video systems (CCTV) with digital recording mechanism (DVR): The development on the market of digital recording systems is not stopping. Today manufacturers use MPEGF4 and H.264 standards to compact data. Data will be stored on HDD-s. The recording units can be accessed already via computer network (internet too), on-line managing of them is also provided. Thanks to spread of smart mobile phones the digital recording units can be accessed, displayed and configured on the smart phones too.
HD CCTV video systems: by using the original infrastructure they enable to install high definition video systems and digital recording units. This is a very expenseful solution used for this reason in Europe very rarely.
Under conditions, HD CCTV systems can become alternative solution for IP-cameras. HD CCTV systems are dedicated to install HD-resolution video systems by using existing coax cable infrastructure. This can be rentable in cases, when replacing an existing cable infrastructure or the installing a new network would result costs, which cannot be covered by the customer.
HD CCTV video cameras are not compatible with original cameras, their data transfer is solved by completely different protocol. Their record resolution is up to 1920×1080 pixels, but instead if standard 25 fps they provide limited frequency.
Except changes caused by HD-resolution (option for mounting more HDD-s, higher graphical display), as physical unit, the digital recorder is very similar to the analog devices. Recorded videos can be displayed also on HD PC monitors, or using HDMI interface on LCD or LED TV-s. Its operation is also very similar to the analogue devices, therefore no special knowledge is needed of their usage.
IP-camera systems: The development of IP-based camera systems got up speed. IP-camera systems communicate with the recording units via PC-networks. Recording is provided by more kinds of devices. The manufacturers provide partially free of charge system operation software enabled to receive “unlimited” number of cameras. As hardware can be used either a standard PC with hardware elements designed for special purpose, or an independent from the camera’s manufacturer recorder, whose manufacturer have integrated more camera types into his system.
Beyond higher record resolution, this market segment is recognized by enhancing of operation function (intelligence). Beside traditional timed or motion sensor recording there are also intelligent system functions to be provided (detecting dropped objects, traffic monitoring, rotating, signing loosing focus, object countering).
In case of IP-video systems the relation of recording and monitoring functions is an important question. To get a well-structured system it is highly recommended to divide these two functions. However it results higher costs, this solution offers more benefits. By building a system like this, the recording unit can be separated physically, therefore the system is protected against sabotage, if safety levels of monitoring units are installed correctly. Augmentation of monitoring capacity doesn’t affect recording points, furthermore, due to the character of this structure recording and recording-monitoring networks can be isolated from each other offering this way a higher safety level.
