Dahua PTZ IP 4MP 4mm – video surveillance camera SD3A400-GN-A-PV raises the bar of performance and supports two-way communication.
Dahua PTZ IP 4MP 4mm – video surveillance camera SD3A400-GN-A-PV raises the bar of performance. After detecting an intrusion, it triggers sound and light alarms and instantly transmits information about the intrusion directly to the mobile device. The system supports two-way communication, enabling real-time communication with people in front of the camera.
Dahua SD3A400-GN-A-PV also uses IR beams to present vivid black and white images for night monitoring. With advanced video algorithm, it supports intelligent functions such as tripwire and intrusion detection. The camera produces vivid images even in high-contrast lighting conditions, thanks to the use of wide dynamic range (WDR) technology. For scenes where light and shadows are rapidly alternating, the WDR adjusts to fully capture both bright and dark areas of the scene.
For active intrusion deterrence and intervention, an audible alarm and a red and blue light alarm are activated in the event of a perimeter violation of the area. There is a wide choice of sounds available as well as the ability to import your own custom ones.

Io ho avuto una ottima esperienza con loro. Mi hanno risposto in tempo reale via whatsapp con precisione, competenza e cortesia, risolvendo ogni problema in un momento difficile come questo. Pochi giorni dopo ho ricevuto il materiale come da accordi.. perfetto. Voto 10
This is a great store: large stock of professional gear, good prices, prompt communication via email / WhatsApp. The dispatch of the order was speedy, and the item arrived super quick in a well-thought packaging. All in all, a warmly recommended new young store, standing out for its remarkable service. Keep up the good work!
It was the first time making a purchase at Martcom, the process was smooth, cameras arrived in proper packing and delivery was quick to Portugal. Thank you for the support on the chat before the purchase. Recommended 100%.
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.

Eccellente sotto tutti i punti di vista! Ho trovato dei prodotti introvabili altrove e li ho ricevuti in tempi ultrarapidi. Servizio clienti di prima classe. Grazie!!
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
Professionalism and availability on the supply of photographic equipment for professionals! Thanks from Nice Shot Art studio !!
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!
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.
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.
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.
