Where do your engineers recommend outdoor security cameras are placed?

Statistics indicate that most (around 55%) of intruders try to get into properties through either the front or back door. So, you may want to have your security camera scoping out your doors. It’s also a good idea to cover other entry points, like back windows, that are hidden away where someone could break in without being seen.

Where exactly to mount your outdoor cameras, however, depends on your property and your individual needs which our engineers and sales team will discuss with you prior to installation. You may have a shed in the back garden that contains expensive gardening equipment, for instance, and you might want to place more focus on that area or cover an oil tank. Perhaps your area has experienced a few break-ins recently, and the intruders typically enter through the garage, so you want to cover your garage area. These are all questions we ask when planning the location of cameras in your home or businesses.


How many security cameras do I need?

Typically, having at least four outdoor cameras is ideal, not including your video doorbell.

If you have a video doorbell to watch your front door, combined with two outdoor security cameras covering the front and back areas of your home, this should be sufficient. Ideally having the cameras cross paths in the field of view with each other would be the optimal scenarios for the best protection of your property.

However, if you have a large property, if you live in an area where there’s a lot of property crime, or if you have vehicles or valuables stored on your property, you may want to add in an extra camera or two.


Can you use an indoor security camera outdoors?

No. An indoor camera does not have the necessary protection from the elements, so it won’t hold up outside.

Some cameras are rated for indoor or outdoor use, and you can use those cameras outside.

If you want to point your indoor camera out a window to watch the outdoors, you technically can do so. However, the camera’s features probably won’t work as well due to glare from the class and reflection of the IR.

We would recommend cameras specifically designed for either an indoor or outdoor environment are installed to achieve the maximum benefits of a robust security system.


Can outdoor security cameras be used indoors?

Yes, although it’s not usually recommended because the cameras designed for outdoor use may not work optimally indoors – they are also generally designed as a visual deterrent and are larger in size. If you require a discrete indoor camera we can provide those options. If you have a commercial premises, vandal proof and IP67 cameras are often used which will work well inside our outside in almost any environment.


Do all outdoor security cameras have two-way audio?

The short answer is no. Many wired outdoor cameras feature two-way audio, which allows you to speak back and forth with someone through the camera via an app on your phone, but not all outdoor cameras have this feature.

If two-way audio is something you’re interested in, there are several factors to consider – one of the main factors is the installation location.

Wind and rain, particularly in Northern Ireland can be an issue when capturing clear audio. Audio recording may also inadvertently pick up the conversations of neighbours or passers-by which unless professionally installed correctly could breach data protection laws.


How well does night vision work on an outdoor security camera?

Night vision on cameras typically uses infrared light to illuminate dark images at night. Essentially, cameras with night vision use this technology to backlight images to help you see what’s happening in the field of view. Most outdoor security cameras feature night vision, but the quality varies from model to model.

We also offer full-colour night vision cameras which use LED’s to illuminate the area or a Starlight / Starvis sensor to produce colour images even in very low light areas.


How well do outdoor security cameras detect motion?

Motion sensitivity in outdoor security cameras varies widely, but generally, the technology works well regardless of the model you choose.

Most cameras do an excellent job of detecting motion if the correct camera is chosen for the specific area and configured correctly, and, if the camera is connected to our app, it will send a motion alert to your phone for immediate review of the alert. Most people find that motion settings on cameras are too sensitive when not correctly set up, meaning that things like spiders, trees moving, pets in the garden or even bright sunlight can trigger an alert. We configure everything and test thoroughly during your professional CCTV camera installation.


Can outdoor security cameras survive severe weather?

Most outdoor cameras have a minimum rating of IP65 or higher, which means they are waterproof and can withstand someone spraying water on them. Our camera ranges come with IP67 as standard which are weather proof. That usually (but not always) means that a camera with that rating can withstand extreme temperatures also.

Cameras vary slightly in terms of survival in extreme weather, but anything with a rating of IP65 or higher will be fine for most climates. If you live in an extremely hot or extremely cold climate, you might want to consider a camera with a rating of IP66 or higher. If you live in a coast area where salt air is an issue, our anti-corrosion range of cameras are most suitable. All of our cameras also come with a built in heater to prevent misting and fogging over the lens during temperature changes.


How long is the guarantee with my system?

Our systems come with a one year warranty – unlike most installation companies, this also includes all cabling and consumables. We only fit high quality, professional and branded CCTV equipment which meets BS:EN standards and our fault rate is <1%.
