Importer - not just a middleman



Importer - "someone whose business involves importing goods from outside (especially from a foreign country)" (Thesaurus dictionary) and "a person, country or company that buys products from another country in order to sell them" (Cambridge dictionary).
Whether it is clothes, food or cctv cameras, our business is not as simple and straightforward as its definition may make it to be...and when cctv products are concerned - far from it! The video surveillance market is wide and consists of various articles that range from small, simple and unchanged for decades (power supplies, accessories....) to complex and dynamic products (cctv cameras, IP cameras, dvr boards, standalone dvrs) to latest developed technologies (IP megapixel cameras, over 600tvl cameras, HD standalone dvr...).
Yes, it is a technology driven market and latest technologies make the rules! Who remembers VCRs, multiplexers and cctv monitors? They have all been replaced in the past decades by dvr boards, DVR standalone and PC monitors. How about cctv cameras? They were big, they had CMOS video boards and they were black/white because the color video boards were too expensive. Now can be fitted with color CCD which can go up to 1020x596 pixels (Effio dsp of Sony), zoom lens and can connect to internet (IP cameras).
We consider ourselves importers of technology and we feel responsible for the quality of products we bring to our country. Therefore we have set up our own set of rules regarding the products we import and offer to clients: all cameras must have color CCDs, 420tvl is the lowest video resolution accepted, the CCDs must be of latest generation, we only purchase from manufacturers which can provide CE, ROHS certification for their products and have R&D team. We check the products and observe how they function in order to anticipate any problems our clients could have and have the answer at hand - from client's point of view it is very important to have your problems solved quickly and correctly and we feel this is the professional thing to do.
Every quality focused importer should first purchase sample products: we conduct quality and functionality check on the sample products to make sure they deliver according to specifications sheet. We feedback our observations to the manufacturer and very often they improve their products as a result. It is of paramount importance to us to standby the products we sell and simply like them - their features as well as their appearance, in order to continue our business relationship with the respective supplier. As a consequence to this principle, we stopped our relationship with two suppliers because the quality of their products has decreased or we felt we couldn't rely on the supplier's support.
The other important relationship is with our clients - may they be professional installing companies or end-users. We provide technical consultancy free of charge to both type of clients in accordance with their needs, trying to achieve a balance between what they need, what they expect, what the current technology can offer them and what they can afford to pay. We feel that the responsibility of professional installing companies is to inform the end-users in respect of what the cctv products can or cannot do, but we are happy to do it ourselves when asked!
At the end of the day, the ultimate satisfaction is to get the call back - the client says he likes the product and wants to keep supplying from our company.

Camere de supraveghere video cu tehnologie Wide Dynamic Range (WDR) cele mai noi caracteristici

Cel mai nou senzor video produs de industria furnizoare de camere de supraveghere video este un chip (sensor) video care prezinta functii ce aduc imbunatatiri uimitoare imaginii surprinse de camera video.Din pacate aceste camere nu se aduc decat la comanda datorita pretului ridicat, contactati http://www.accentcctv.com

Imbunatatirile sunt :

Functia A.B.C. = prescurtare de la ADAPTIVE BLACK COMPENSATION (compensare flexibila a nivelului alb/negru)

Aceasta functie permite camerei cu DSP wide dynamic sa detecteze zonele intunecate ale imaginii si sa le corecteze automat, luminandu-le in mod natural si in consecventa cu imaginea in ansamblu.

Culoare de 14bit HIGH
Imaginea digitala este compusa din pixeli de nuante si dimensiuni diferite care impreuna, intr-o anumita ordine formeaza imaginea. Detaliile continute de imagine depind de cantitatea de informatii – un numar crescut de pixeli produce o imagine mai detaliata, mai clara. Numarul de biti folositi pentru a reprezenta fiecare pixel determina cate culori pot fi prezentate. De exemplu, 8biti inseamna ca se folosesc 8 biti pentru fiecare pixel, ceea ce face posibila vizualizarea a 256 de culori diferite. 10biti inseamna 2 la puterea 10 = 1024 de culori, iar 14biti = 16384 de culori. Imaginea cu scara de 14biti mareste claritatea culorilor si ofera imagini care se apropie de calitatea celor 3D.

Functia 3D DNR (DIGITAL NOISE REDUCTION)

Acest senzor este obtinut printr-o procedura speciala care preia atat sensibilitatea CCD-ului cat si performanta high wide dynamic a CMOS-ului. Ofera in acelasi timp imagini de inalta sensibilitate si claritate si in conditii de luminozitate scazuta (0,1lux). Senzorul 3D DNR scade nivelul zgomotului si confera imaginii culori reale in lumina slaba.
