When it comes to surveillance, a video doorbell is typically the entry point for many consumers, and with good reason. Video doorbells provide triple-duty functionality of not only being a doorbell, but also a surveillance camera that you can use to monitor your front door, entryway, or porch, and an intercom that enables two-way audio communication with visitors at your door. The value proposition of a singular device that does all this is evident.
For some consumers, a video doorbell will take care of all of their surveillance needs. However, much more is possible. Consider the DH-DB6I from Dahua Technology, for example, a Wi-Fi video doorbell that can be used as part of a larger surveillance ecosystem featuring other surveillance devices from the brand. On its own, the DH-DB6I is a very capable surveillance device that offers 5MP video resolution, IR illumination for visibility in low light, motion and human detection, and two-way talk thanks to a built-in speaker and microphone.
The easiest way to expand the functionality of a doorbell is by adding a chime. Something like the DH-DS21 LincX2Pro can be later added to the DH-DB6I video doorbell or bought together as a kit. The DH-DS21 LincX2Pro expands the ringtone options you can use to be alerted when someone is at your door and can be linked to multiple compatible video doorbells simultaneously.
Beyond chimes, the DH-DB6I is compatible with Dahua Technology NVRs, along with the X5, X7, and X82 HD-CVI DVR series. When connected to a recorder, the video doorbell functions as an additional video channel. Some NVR kits are available with the doorbell bundled with cameras as one of the video channels. However, the potential combinations with compatible recorder kits with specialized cameras are nearly limitless and offer key benefits. One of those benefits being complete control under one ecosystem. The recorders, doorbell, and cameras can be managed remotely with the Dahua DMSS mobile app for iOS and Android.
Implementing a video doorbell in a surveillance system that includes specialized cameras adds an additional layer of security. Specialized cameras include the Three-In-One (TiOC) camera line, like the A52CJC2 5MP HD-CVI turret camera. Like all TiOC cameras, the A52CJC2 offers a proactive video surveillance solution that lets you prevent or deter an incident before it happens via smart illumination and live warnings.
TiOC cameras feature perimeter protection and smart motion detection. They can be customized and configured to activate red and blue flashing lights the moment motion is detected after a perimeter threshold or a defined line has been crossed. In addition, a siren with a myriad siren alerts can be activated for another layer of deterrence. In tandem with the siren, pre-recorded messages and voice prompt commands can be sent through the camera’s speaker as a live warning to any intruder or unwanted visitor.
With the video doorbell utilized for entryway coverage, the specialized cameras can be used for other vulnerable locations or areas where you wouldn’t have or need a doorbell, culminating with both the doorbell and cameras functioning as video channels covering all bases for the same recorder for one seamless surveillance solution.
