Dahua Eyeball IP 4MP 2.8mm – video surveillance camera IPC-HDW2431T-AS-S2 features more efficient video decoding capability, which saves bandwidth and storage space.
Dahua Eyeball IP 4MP 2.8mm – video surveillance camera IPC-HDW2431T-AS-S2 features more efficient video decoding capability, which saves bandwidth and storage space. The Starlight technology on-board provides color images even in dimly lit scenarios. Dahua smart encoding technology provides high-quality video and savings in storage and transmission.
The camera captures vivid images even under the most intense contrast conditions. True WDR (120 dB) optimizes both overexposed and dark areas for perfect video. By adopting large pixel sensors and smart algorithms to process images, the camera provides unparalleled performance even in dimly lit environments. Dahua IPC-HDW2431T-AS-S2 also supports advanced authentication, authorization and encryption technologies for transmission and storage to ensure data security, as well as smart video analytics features such as tripwire (line-crossing) and intrusion.

just bought from Martcom, payment via Paypal, package sent via DHL, received in 4 days in France, excellent package, material in new mint conditions and prices super attractive. They have a big stock in Kupo accessories and that’s quite rare in Europe. I recommend Martcom !
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!
Once again, excellent service from the team at Martcom in relation to my recent order. Very helpful and responsive to all my questions. Highly recommended.
Da subito gentilissimi e a disposizione per qualsiasi chiarimento. Competenti e professionali sotto ogni punti di vista, pronti a consigliare ed aiutare, per toglierti ogni dubbio riguardo l’utilizzo o la scelta della strumentazione di cui necessiti. Sicuramente ripasserò a comprare in negozio da loro o se necessario a noleggiare.
Ich habe bei Martcom ein Bodenstativ gekauft, dass in Deutschland zur Zeit nicht lieferbar ist. Der Onlineshop ist übersichtlich und einfach zu bedienen. Den Kauf habe ich über Paypal abgewickelt und innerhalb von 3 Tagen nach Deutschland geliefert bekommen. Die Ware und die Abwicklung über Martcom haben meine Erwartungen übertroffen. Vielen Dank
Negozio online serio che ha risposto in modo rapido e amichevole alle mie domande. La spedizione è stata super veloce e la merce corrispondeva alla descrizione. Noi raccomandiamo. Grazie mille.
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.
These guys are amazing! Thank you for your job. I got a camera delivered to Cyprus in 2 day – it’s almost unbelievable. Also they are a certified Canon reseller that I had personally confirmed with Canon officials (having bad experience in the past with another online store). Will be coming back for more gear if needed any filming equipment when in Europe 👍.
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.
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!
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.
A pleasure to do business with. Was looking for Canon R7 and Martcom was the only place I could find it in stock. Very competitive price, and communication with the company was excellent throughout the process. Delivery 3 days earlier than expected. Would recommend Martcom and would definitely use again.
