Power boxes are designed for a large number of cameras situated at close range. They have multiple outputs and each one is equipped with overload protection (recoverable or non-recoverable), allowing the system to maintain working state and power the healthy branches in case of failure of any of them. All power boxes are equipped with high-reliability power supplies with up to 5 years warranty .

In addition to the standard functions, "Zahranvane Com" also offers a channel mailfunction alert with front panel LED indicatior and dry relay contact output, which can trigger any external security system. There is also ongoing development of a remote monitoring and control module.

Power boxes in this category are designed to be connected to solar battery systems or UPS emergency power systems. Used power supplies are specially designed for safe operation in DC mode and are highly reliable and highly efficient. Single-stage conversion without the use of a 230VAC inverter guarantees minimal conversion losses and gives a significantly longer backup time compared to an inverter system with the same batteries. Battery voltages of 12V to 144V are supported.

The models with 12V output voltage also offer a fault-tracking feature with front panel LED indication and a dry relay contact to trigger an external security system.

The converters in this category are specially designed to be powered by 24VAC transformers. The list includes isolated conveters with high-end protection and picture quality, and non-isolated budget models which can be used in cases where each camera is powered by a separate transformer.

Long distance CCTV power supplies are extremely effective for a surveillance over long cables at large commercial and industrial sites, ensuring a centralized power supply to all points. This increases the overall reliability of the system, simplifies its maintenance and uninterruptability.

Presented models cover different number of branches and distances. They can be connected to a 230VAC UPS to provide uninterruptable power to the line. They are equipped with reliable current and temperature protections that maintain the system's safety in case of a cable insulation breakdown.

To provide maximum protection for cameras and DVRs when operating over long cables and with high voltages, all available converters are isolated. Listed devices differ in both voltage and power, as well as the class of protection they provide.

Designed for powering PoE-compatible cameras or other equipment, these converters are equipped with RJ45 data input and RJ45 output for data + power. Models POE (100mbps) and GPOE (1Gbps) with an input voltage of 50V to 200V DC can be used with long distance power supplies uCCTV/nCCTV and are galvanically isolated.

BA90 devices are best suited for 12V or 24V battery operation providing higher output voltage with all the necessary protections. They can be used with a buffering power supply and a battery or connected directly to a solar powered 12/24V system.

When network segmentation is required, intermediate (mid-point) converters may be used to isolate potential vulnerabilities. They output a stable line voltage, isolate output line from the remaining segments, and if any problem occurs in this area, they retain the operateability of the rest of the system.

The AP12-3 buffering controller can be installed in a security system with available transformer power supply. It provides a constant current battery charge while supplying power to the equipment. In the event of an AC power failure, the equipment continues to operate sourcing current from the battery. Deep discharge protection is provided to extend battery life. The charging current and maximum voltage can be adjusted depending on the battery used and the expected mode of operation - cycle or stand by.

On higher voltage lines it may be necessary to use a local UPS at the load point in certain cases. The V16-14R, V16-28R and V16-5R models provide this function using an external lead-acid 12V battery of your choice. They can also be very useful when powering equipment which peak current exceeds the average - for example, GSM/GPRS communicators. In this case, a power module with a relatively low average power can be installed, at peak times the current will be drawn from the battery, and in the rest of the time the battery will be recharged. Devices are provided with deep battery discharge protection and input to output isolation.

The isolators listed here are suitable for systems where one or a few cameras are located on a long distance from the main dashboard, as well as in cases of noisy environment. When installed next to the camera, the module's galvanic isolation eliminates image distortion of an analog camera, and also provides constant 12V voltage no matter if the backlight is on or off. Another frequent application of these modules is to power a camera or other multimedia in a car. The closed ground loop through the chassis causes image and sound distortion, which can be prevented using power supply isolation.

The ISO-12W and ISO-12R compensators are based on the ISO-12HD isolators but they are designed to be used next to the power supply and are best fitted in cases where placing a converter next to the camera is not acceptable. In addition to output regulation and galvanic isolation, they provide the option of cable compensation. They output such a voltage to compensate cable losses so the camera receives exactly 12V regardless of the "day"/"night" mode and power consumption. One of the models (ISO-12W) is used to monitor the chassis of the video signal and is very handy if the DVR (or video cable) is close to the power supply. The other model (ISO-12R) does not need an additional wire, but requires initial calibration when installing.

All converters accept wide range input voltage making them suitable for:

• 12V surveilance power supplies;
• 12V or 24V solar powered systems;
• passanger cars, trucks, busses with 12V or 24V onboard voltage.
