Security cameras or surveillance cameras have become omnipresent in cities and towns across the world. It has become a necessary element in protecting society from delinquent people. More often than not, security cameras are actively monitored by law enforcement or security guards.
There is no limit to where you can install these devices. Wherever people are, there will always be a need to deter crime, alert law enforcement, and to provide evidence. They can be found in airports, offices, shopping malls, constructions sites, residences, etc.
There are various degrees of expertise that will be needed to install these cameras based on your surveillance needs. If it is at your home, the task would be small enough for you to install it yourself. The technology available today is easy enough for anyone to understand as it just involves the camera, cables, and a Digital Video Recorder (DVR). However, there will be some time consuming manual labour involved if you go with the cheaper wired option as you will have to run the cables from the cameras to the DVR.
There are several benefits to having security systems in the home and office as not only will they deter crime, but it will also enable you to receive a discount from most insurance providers, and increase employee productivity.
Which Security Camera Suits your Needs?
When choosing a camera for your home or office, you will need to be clear about your surveillance needs. You will have to ask yourself a few questions before making any purchases. Which area of the home or office do you want to focus on? Will it be in one specific room or several rooms in the home or office? Do you need indoor, outdoor, or both? The answers to these simple questions will determine the number of cameras you will need and the system that will be required to operate it. Complexity of the task will determine the camera system that will be required.
If you want to be discreet, it is better to go wireless. Wireless security cameras come with more flexibility, but they can also have issues with interference from various wireless signals in the air that may cause interruption. If you decide on a wireless option, ensure that the signal that is emitted is an encrypted one. No one wants to encourage voyeurism and the possibility of being watched by criminal entities defeats the purpose. Although it will be harder to hide the wires from a wired security camera, they tend to be cheaper and usually have better image quality.
When it comes to analogue cameras, there are many options to choose from. These CCTV cameras are usually models that are dome shaped or bullet shaped. Some examples of these devices are as follows:
- Vandal Dome Camera with IR 0.0 lux 1/3″ CCD 500TVL Day/Night 12V DC OVC-VDIR500DN
- Samsung 43x Zoom 600TVL SmartDome TDN/WDR PTZ Outdoor SCP-3430H
- Vari-focal Vandal Dome Camera 1/3″ CCD 600TVL IR Cutfilter Day/Night Dual Voltage OVC-VD600DNC-VF
- Samsung 1/3 IR Day Night Camera High resolution Vari Focal Lens SCO-2080R
- High resolution Full Bodied Camera 1/3″ CCD 600TVL IR Cutfilter Day/Night 12V DC OVC-F600DNC
- High resolution Full Bodied Camera 1/3″ CCD 540TVL IR Cutfilter AWB Day/Night 12V DC OVC-F540DNCWP
IP cameras also come with an image dome and bullet option. Unlike their analogue counterpart, Internet Protocol cameras can send and receive data from a computer network and the internet making it ideal for remote viewing. Some examples of these security cameras are as follows:
- ACTI IP Dome Camera VGA IR Day Night PoE ACTI-ACM-3011
- Axis-M3204v Fixed Vandal Dome Camera AXIS-M3204V
- Axis-P3343 6mm SVGA Day Night Fixed Dome Camera AXIS-P33436

- AXIS HD 720P/1MP IP Camera, JPEG-H.264, Out Door Ready, IP66 Housing & Bracket AXIS-M1114E
- Axis Outdoor 1M/HDTV 720P Camera Day Night Outdoor-ready, IP66 rating AXIS-P1344-E
When setting up your surveillance system, it is always better not to choose the cheapest option. There are several low end security cameras out there and they always have issues such equipment malfunction, poor resolution, and brackets that are unable to hold the camera.
Analogue wireless security cameras are great, but electricity is needed to power the device. As a result there will be issues with the cables that power the system. Further, wireless devices such as mobile phones can interfere with the signal. So if it is possible, it is best to choose a digital wireless camera or a hardwired analogue security camera.
When setting up a CCTV surveillance system, it is always better to use multiple PTZ cameras to cover any specific area as they can tilt, pan, and zoom. But if there isn’t anyone actively monitoring the cameras at any given time, it is best to go with multiple cameras avoid blind spots.
