TP-Link VIGI C240I (4mm)
Vigi 4MPx venkovní IR dome síťová kamera
Velmi vysoké rozlišení 4 MPx : Kamera VIGI C240I má rozlišení 4MP – více než dost pixelů pro zachycení některých diskrétnějších detailů.
Rozlišení osob a vozidel : Rozlišuje lidi a vozidla od ostatních objektů, takže dostáváte přesnější oznámení o událostech.
Inteligentní detekce : Přijímejte oznámení a kontrolujte kanály, když někdo překročí hranici, vstoupí do nastavené oblasti, překáží kameře nebo odstraní/opustí objekty.
Odolnost proti vandalismu IK10 a voděodolnost IP67 : Tato dome kamera VIGI s robustním krytem proti vandalismu a vodotěsným provedením je konstruována tak, aby odolala vandalismu a drsnému prostředí s deštěm a prachem pro neustálé zabezpečení kdekoli a kdykoli.
H.265+ : Kamery přenášejí komprimovaný křišťálově čistý obraz, aniž by využívaly další šířku pásma, a šetří tak místo na disku, snižují zatížení sítě a náklady na monitorování – to vše bez snížení kvality obrazu.
Chytré vylepšení videa : Profesionální technologie VIGI zpracovávají videa a výrazně zlepšují jejich kvalitu, která je pro vaše sledování zásadní, včetně Smart IR, WDR, 3D DNR a nočního vidění.
PoE/12V DC : Dva typy napájecích zdrojů vám poskytnou nejen větší pohodlí, ale také pozoruhodně usnadní zapojení.
Objektiv 4 mm : Kamera C240I se dodává se dvěma různými typy objektivů, které lépe vyhovují vašim bezpečnostním potřebám, ať už potřebujete širokoúhlý objektiv pro pokrytí uzavřených prostor, nebo objektiv s vyšším milimetrovým rozsahem pro delší vzdálenosti v otevřených prostorech
Flexibilní správa : Převezměte plnou kontrolu nad svým zabezpečením prostřednictvím čtyř způsobů správy: webového uživatelského rozhraní, uživatelského rozhraní NVR, aplikace VIGI a nástroje VIGI Security Manager.

Multicast TV VLAN Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR)
VLAN Translation Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN
Q-in-Q VLANs transparently cross a service provider network while isolating traffic among customers
Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs
Selective Q-in-Q also allows configuring of Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag
Layer 2 protocol tunneling over Q-in-Q is also supported
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain

Supports time-based 802.1X; dynamic VLAN assignment; MAC authentication
IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)
Web-based authentication Web-based authentication provides network admission control through web browser to any host devices and operating systems
STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops
STP Root Guard This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers.
IP Source Guard (IPSG) When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing.
Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks.
IP/MAC/Port Binding (IPMB) The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DOS attacks in the network, thereby increasing network availability

IGMP proxy The IGMP proxy provides a mechanism for multicast forwarding based on IGMP membership information without the need for more complicated multicast routing protocols.
Head-of-Line (HOL) blocking HOL blocking prevention
Loopback Detection Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP
Layer 3 IPv4 routing Wirespeed routing of IPv4 packets
Up to 990 static routes and up to 128 IP interfaces
IPv6 routing Wirespeed routing of IPv6 packets
Layer 3 Interface Configuration of Layer 3 interface on physical port, Link Aggregation (LAG), VLAN interface, or loopback interface
Classless Interdomain Routing (CIDR) Support for classless interdomain routing
RIP v2 Support for Routing Information Protocol version 2 for dynamic routing
Policy-Based Routing (PBR) Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 Access Control List (ACL)
DHCP Server Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options
DHCP relay at Layer 3 Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BOOTP)/DHCP packets
Stacking Hardware stacking Up to 4 units in a stack. Up to 200 ports managed as a single system with hardware failover
High availability Fast stack failover delivers minimal traffic loss. Support link aggregation across multiple units in a stack
Plug-and-play stacking configuration/management Active/standby for resilient stack control
Autonumbering
Hot swap of units in stack
Ring and chain stacking options, auto stacking port speed, flexible stacking port options
High-speed stack interconnects Cost-effective high-speed 10G fiber interfaces.
Security ecure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (SCP) also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
IEEE 802.1X (Authenticator role) 802.1X: Remote Authentication Dial-In User Service (RADIUS) authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions
Supports time-based 802.1X; dynamic VLAN assignment; MAC authentication
IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)
Web-based authentication Web-based authentication provides network admission control through web browser to any host devices and operating systems
STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops
STP Root Guard This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers.
IP Source Guard (IPSG) When IP Source Guard is enabled at a port, the switch filters...
