Dahua Bullet IP da 8MP 2.7-13.5mm con AI WizSense – telecamera IPC-HFW3849T1-ZAS-PV supporta funzioni intelligenti di videosorveglianza.
Dahua IPC-HFW3849T1-ZAS-PV adotta un algoritmo intelligente per rilevare bersagli. L’illuminatore IR è generalmente acceso di notte: quando il bersaglio appare nell’area di monitoraggio, la luce calda si accende e la telecamera registra il video a colori e le informazioni sugli eventi chiave. Filtra gli oggetti che non sono bersagli come animali piccoli e grandi per evitare di innescare falsi allarmi.
Questa telecamera IP è inoltre dotata di una serie di tecnologie chiave come autenticazione e autorizzazione di sicurezza, controllo degli accessi, protezione affidabile, trasmissione e archiviazione crittografata. Queste funzioni migliorano la sicurezza delle informazioni e impediscono ai programmi dannosi di violare il dispositivo. La camera è disponibile anche in finitura nera, su richiesta.

What i ordered came really fast and the whole process was smooth and easy. I will definitely buy again and again from these guys.
I’ve made purchase from this company a couple of times and found them to be highly reliable, well priced and stocked and easy to contact. Their ‘chat now’ really works (so many web sites offer this, only to disappoint) and the responses are fast and full, so need need to keep going back. I think this is a very good company, with a great catalogue of quality gear (esp their range of Kupo products) and so much of it seems to be in stock which is often not the case, especially here in the UK where since leaving the EU (regrettably) we seem to be suffering huge stock delays. So I am happy to recommend Martcom.
Rivenditore affidabile, servizio clienti molto buono. Ottima la possibilità di ritirare il materiale a Milano in alternativa alla spedizione. Consigliato.
ordering was easy and they were the only place in europe to have the camera in stock. posted to the U.K. without any problem.
Serious online shop that answered my questions quickly and friendly. Shipping was super fast and the goods matched the description. We recommend. A thousand thanks.
Absolutely happy I discovered this shop. The team were very responsive on whatsapp and even I hopped on a phone call so they help me a bit with my choices. They were very happy to help and they really know their products. I ordered several profoto products and they helped me make sure they are what I need. I live abroad so they helped me find the lower prices for shipping. I HIGHLY recommend them. As of now I will shop gear with them!
First time I bought equipment from them, nothing to complain, professional staff and kindness. The equipment was in perde condition and I received a pretty quick email about when to go to pick up my goods. Excellent experience
First time buyer was wary buying from Italy. Bought a Canon EOS R7 which is impossible to get in the UK without being on a several month waiting list. Well packed and come next day delivery with DHL. Happy to recommend !!
Falsely advertised free shipping for over 500 Euro spend as it says at the top of home page. Placed a large order, no shipping cost added (free) then next day receive an email asking for 420 Euro shipping fee to Cyprus also in EU. Despite highlighting their misleading terms and conditions to them they refused to send the goods. Would not recommend this company as they don’t honour the contract of sale but make excuses after buyer pays.
Ho acquistato nei giorni scorsi una fotocamera e non posso che esprimere un parere favorevole sia per l’assistenza durante l’acquisto che per la serietà professionale e la gentilezza del personale.
I ordered Angelbird CFExpress cards (which were not available anywhere in the U.S.) and Martcom was able to find stock and sending me some, which I could not be happier about. Customer service was very fast and helpful, as I received regular updates about my item’s availability. Thank you Martcom!
Perfect experience and customer support. There was an issue with the availability of some items and the shop owners quickly proposed alternatives, followed up personally and delivered on their promise. The delivery was fast, efficient, the package we’ll protected and the prices really affordable. 100% would recommend!
I stumbled upon Martcom because they offered the lowest price on an item I was looking to purchase, but I will definitely buy again from them because of the EXCELLENT customer experience I had communicating with them. They really went beyond my expectation of good service.
