Hikvision DS-2CD2432F-IW Camera Review

Hikvision is a big name in the IP camera industry, offering a wide range of cameras that cover the whole spectrum from small home-use cameras to professional high-resolution industrial models.

Features

The DS-2CD2432F-IW is an inexpensive ($130) compact camera suitable for indoor use, with an impressive feature set. The 3 MP sensor offers higher resolution than many competing products from other manufacturers (Hikvision themselves also produce a DS-2CD2412F-IW model with a lower 1.2 MP resolution, but the price difference is not large, so we we would recommend going for this 3 MP model). It has both WiFi and Ethernet connectivity, and can be powered either by PoE (Power-over-Ethernet) or by a 12v power adapter, making it easy to install in any network environment. The sensitivity of 0.07 Lux, combined with built-in infrared (IR) illumination, allows it to function well in low-light situations, and it has a built-in microphone and speaker for two-way audio.

Case Study: The Raven Hotel

For any organisation still using analog cameras, SecuritySpy offers an easy upgrade path to a digital solution, allowing you to keep your analog cameras while gradually moving to a system based on megapixel IP cameras.

The Raven Hotel was in exactly this situation, and used SecuritySpy as their video surveillance solution. Below is their experience of SecuritySpy, in their own words.

CaptureSync Case Study – Trio Iguaçu

Trio Iguaçu is a talented group of musicians, playing a delightful blend of tango and bossa nova music. We set up a recording session with them in order to produce promotional videos for the trio, as well as to demonstrate the power and flexibility of our CaptureSync multi-camera video recording software.

CaptureSync is software for the Mac that records video and audio from multiple cameras simultaneously, with all feeds synchronised together and saved to a single QuickTime Movie file. CaptureSync is perfect for recording interviews, scientific experiments, psychological research, musical performances, market research, lectures and presentations.

The setup consisted of one main camera to capture the whole group, as well as three auxiliary cameras to provide close-up views of each musician. These close-up views are useful for analysing playing technique or for editing in Final Cut Pro in order to produce an edited movie that switches between multiple camera angles.

Main Camera

As the quality of the group view was the most important, we used a Nikon D3200 DSLR camera with a 35mm lens. This camera provides high-quality 1920×1080 resolution 30fps video via HDMI, which can be recorded by CaptureSync using Blackmagic HDMI input hardware. As we were using a Mac Pro computer, we used the PCI version of their Intensity product, which is part of a range that also includes Thunderbolt and USB 3.0 HDMI-input devices.

A Field Study Using CaptureSync

In a now-famous experiment initiated by the Washington Post, world-renowned violinist Joshua Bell performed undercover in a busy metro station. Using a priceless Stradivarius violin, Bell performed music that he normally plays in front of large concert audiences around the world. The result? Hardly anyone paid much attention to the violinist, or tossed many coins into the open violin case by his feet. The experiment provides a fascinating insight into the importance of context in our experiences of the events around us.

The performance was recorded, but only by a single low-quality camera. What if we wanted to record the experiment properly, from multiple angles, in order to analyse every aspect of the event and people’s reactions? This is the kind of task that CaptureSync is perfect for, and the setup of this hypothetical recording is detailed below.

Firstly we will consider the layout of the space, and where the best camera angles will be:

Adding Live Video To Any Web Page

This tutorial will show you how to add live video from SecuritySpy to your own web page. This does involve editing the HTML of your web page, but it’s relatively simple. Our favourite tool for this is TextMate.

Firstly, you must set up SecuritySpy for remote monitoring, so that it can be accessed over the internet. Next, create a special user account in SecuritySpy that has permission only to view the camera that you want to use. Finally, determine the camera number for the camera in question – this is shown in the Camera Info window (highlighted in red below). If you don’t see this column, click the header bar where you see the column names, and a menu will pop up that allows you to add it.

Three methods for embedding the video feed into a web page are outlined below. In the HTML examples shown, the address of the SecuritySpy system is “demo.viewcam.me”, the port is 8000, and the camera number is 1. The authentication is “user” and “pass” for the username and password; you should substitute the actual username and password for the account you set up.

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.

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.

Network Streaming Protocols
There are two main protocols used for carrying video and audio data over IP networks: HTTP and RTSP. Using these protocols, it is possible to transmit video and audio in various compression formats (JPEG, MPEG-4, H.264, AAC etc.).
