CCTV Buyer's Guides

Buyers Guide

Part 13: Digital Video Recorders (DVRs)

At the heart of any CCTV system, it’s the recording of video evidence that is crucial when it comes down to catching a criminal so it’s worth buying wisely and paying a little extra to give your customer extra peace of mind.

Buyers Guide

Part 11: PTZ Cameras

Perhaps what springs to everyone’s mind when they hear the words CCTV but also somewhat off putting for the rookie CCTV engineer. Here are a few things to look for when picking out the right PTZ camera for your installation.

Buyers Guide

Part 9: Test Monitors

It's important not to waste those precious minutes struggling to troubleshoot an installation problem. A CCTV test monitor is well worth the initial outlay.

Buyers Guide

Part 7: Baluns

Baluns can make use of an existing network structure in a building by using a single CAT5 cable to send 1, 2, 3 or even 4 real-time video signals from one location to another.

Buyers Guide

Part 5: Microphones

In certain situations, the ability to listen to a conversation or altercation is key, it may even provide valuable evidence that will lead to a criminal conviction.

Buyers Guide

Part 3: Monitors

Unlike TVs in our own homes, the screen we use to view our CCTV on is often almost an afterthought with little attention paid to some of the details that can make a big difference in ease of viewing recorded footage.

Buyers Guide

Part 1: CO–AX Cable

Choosing the right COAX cable for your job is critical as getting it wrong can mean wasted hours of first fixing that needs redoing when the results are sub-standard.

Buyers Guide

Part 12: Dummy Cameras

Dummy camera's are a great low cost way to boost the presence of on-site security. They’re realistic and most people couldn’t tell the difference between a good quality dummy and a real camera.

Buyers Guide

Part 10: Eyeball Cameras

Probably the most popular style of camera thanks to its sheer versatility in terms of mounting it on a ceiling or wall and looking the part both indoors and out.

Buyers Guide

Part 8: Covert Cameras

A covert camera can be the ideal solution to catch an unsuspecting culprit when they least expect it.

Buyers Guide

Part 6: Video Door Entry

A basic video entry system that works as a standalone system or can be integrated into an existing CCTV system offers an easy add-on sale.

Buyers Guide

Part 4: Wirefree Transmission

Using wirefree technology to transmit video and audio signals from one point to another is a great “get out of jail” card when cabling is difficult or costly perhaps due to a road or some other obstruction.

Buyers Guide

Part 2: PSUs

Powering cameras and recording equipment in the right way is critical to a lasting & quality CCTV installation. Get it wrong and you could waste hours trying to correct voltage drop issues and interference.
