Intercom Rankings - Aiphone, Akuvox, Alocity, Avigilon Alta, Axis, Axis 2N, DoorBird, Hanwha, Hikvision, Verkada
Intercoms have become a fundamental component in video surveillance, with various manufacturers introducing their IP Video Intercoms for commercial and residential sites. But which manufacturer is the best in real-world testing?
IPVM tested ten different IP video intercoms, including the Aiphone IX-DVM, Akuvox E12W, Alocity F3D100, Avigilon Alta Video Intercom Reader Pro, Axis A8207-VE MK II, Axis 2N IP Style, DoorBird D1101V, Hanwha TID-600R, Hikvision DS-KV9503-WBE1, and the Verkada TD52.
This report details the strongest and weakest intercom performances from the following categories:
- 1:1 Calling
- 1:N Calling
- Audio Quality
- Day Time Image Quality
- Device Integration (RS485, IO, Relay, etc.)
- Call Routing
- Event Generation Latency
- Methods of Entry
- Mobile App Support
- Night Time Image Quality
- Noise Cancellation
- SIP Compliant
- VMS Integration
- WDR Quality
- Wiegand / OSDP Support
As well as a summary of additional offered features in each tested intercom that would influence an end user's purchasing decision:
- Access Management Tools (Credential issuing / locking, etc.)
- Built-In Physical Readers
- Facial Recognition Offered
- Motion Detection
- Remote Unlock
- Secure I/O Module Offered by Manufacturer?
- Touch Screen
As with all IPVM research, these results may NOT be used promotionally, as it violates our terms of service and is against our fundamental philosophy of independence and research, not marketing.
