Dahua IPC-HFW2831T-ZAS Camera Review

The IP camera market is replete with bullet-style cameras, with Dahua Technology being one of the major manufacturers of cameras of this type. Basic Dahua bullet cameras are well-designed, inexpensive, and generally provide good quality video, however it doesn’t cost too much more to get a model like this one, which has some key features that allow it to perform much better than basic models.

Dahua IPC-HDW5831R-ZE IP Camera Review

Dahua Technology have such an extensive range of IP cameras that it can be difficult to choose between them, especially between models that are superficially similar. Generally, Dahua cameras work very well with our macOS CCTV software SecuritySpy, and this particular model, the IPC-HDW5831R-ZE, looks like it could be something special.

This is an “eyeball” type camera, which is a form factor with some significant advantages: they are generally compact in size, easy to swivel and rotate to the correct position, and, unlike dome cameras, there is no curved perspex dome in front of the lens to reduce quality.

AXIS A8105-E Video Door Station Review

Video doorbells are becoming increasingly popular, and have the potential to make a useful addition to any CCTV system. Our macOS CCTV software SecuritySpy works with many different video doorbells, but choosing one to use can be difficult, as they vary significantly in terms of feature set, quality, reliability and cost. In addition, many video doorbells (e.g. Ring, Nest, Eufy) are designed as closed cloud-based systems that lock you into a subscription, and specifically don’t work with NVR (Network Video Recorder) software such as SecuritySpy.

Features

The Axis A8105-E doorbell offers a good all-round feature set, including 2 MP resolution, Power-over-Ethernet, two-way audio, compact design, and multiple input/output ports to connect accessories such as chimes and door openers. A 1.56mm lens provides an outstandingly wide 180º horizontal field of view and the ability to capture people very close to the camera.

SecuritySpy and ONVIF

SecuritySpy is our flagship video surveillance software product for Mac OS X, and as of version 3.2, SecuritySpy supports the ONVIF protocol. Here are the answers to some common questions, and information about this new feature.

What is ONVIF?

ONVIF is an open industry standard for IP-based video surveillance products. In the past, SecuritySpy would have to be pre-programmed with profiles for each camera it supports, containing information about the supported streaming formats, audio capabilities, communication ports, resolutions, frame rates, Pan/Tilt/Zoom features etc. This is inconvenient and time-consuming for us as developers, and also bad for customers because there is an inevitable delay between a new camera coming on the market and an update to SecuritySpy to officially support it.

With ONVIF, all this information can be obtained from the camera automatically. Therefore, any new ONVIF-compliant camera hitting the market can be immediately used with SecuritySpy using the ONVIF setting built into the software.

However, it’s a fast-changing market and new cameras are continuously being released. While we do our best to release frequent updates that support these new cameras, it’s a difficult task. You may find yourself intending to use a particular camera that is not yet on our list – this blog post will show you how.

Comparison of Streaming Formats

The latest version of SecuritySpy supports new streaming formats which significantly enhance compatibility with new and existing network cameras. The following information about these formats will be useful when making purchasing decisions and setting up video surveillance systems based upon SecuritySpy.
