Installing Security Cameras - Explained in Pictures & Diagrams

installing security cameras

To recount a personal experience. I once took a cab from Philadelphia to a neighboring place, Willow Grove, in the suburbs to visit an aunt, kind of give her a surprise. It was a bit late, at around 10 PM. The minute I walked out of the cab and approached the house, lights came on covering the entire place. The cops followed suit in a couple of minutes. It was a hair raising experience. The aunt turned out had shifted from Willow Grove. But I was truly impressed with the nightvision security systems installed, one that clearly demonstrated the need and efficacy of a well thought out security system in place. The trick to installing a surveillance camera is that it should not be so evident that a trespasser can disable them. Kind of defeats the purpose. Let’s get on with how to install security cameras.

How to Install Security Cameras?

It's easy to install a wireless security camera but wired cameras call for a medium level of difficulty. The first bit is what kind of security cameras do you want to install; wired or wifi. Wired gives you more clarity, and WiFi is hassle-free. Opt for the battery-operated models for greater flexibility and ease of installation. And there’s no messy wiring. Since night vision is required, a PoE (Power over Ethernet) IP camera is what we will install. We will be doing the camera installation on our own, so here’s how.

Where to Install

  1. Choose your spot with care. A study carried out points to 34% of burglars using the front door. It’s also obviously where package thieves strike.
  2. It should be placed high enough for a wide enough field of vision and covering as many entrances as possible. You want to avoid extra costs.
  3. Avoid pointing it towards a light source directly. This will cause under-exposure of images being captured.
  4. The chosen position should be close to a powerpoint.
  5. Weather protection should be factored in. Mount the camera under an eave or similar protected location.
  6. Do not install under a window. The infrared reflection will render images over-exposed.
  7. As a courtesy to your neighbors, do not position an outdoor camera close to their property as it amounts to an invasion of privacy, or worse getting suspected of being a ‘peeping Tom’.

Mounting On Walls and Wire Management

Arranging the wiring and associated cables for your CCTV camera installation is the biggest bother of the entire project. Plan beforehand as to where the monitor is going, available paths and routes how it is to be laid out. You don’t want an ugly tangle at the end. We will focus on how to install wired security cameras as it is basic and often the choice.

  1. Get familiar with the mounting bracket.
  2. Assuming you have located the ideal spot, drill holes and mount the bracket.
  3. Two wires along with the connectors come with each cable. One is for recording and the other for the power supply.

Connecting and Powering Up

It is a definite requirement that all power connection is through an uninterrupted power supply (UPS). Cutting off the power supply externally is the first act of felons. If your fallback system is a generator, connect it up accordingly.

Professional Tips for Installing Security Cameras

  • Choose a panoramic security camera that can produce images at 360-degrees.
  • If your cameras are high-end wire-free, skip this. Power access at all times is a must.
  • Be practical. Connect up everything, test the entire system before progressing to installation.
  • Before mounting, that is before you start drilling holes, hold the camera in position, get help from a buddy that the image quality, field of vision, etc. are all acceptable.
  • Especially check for blind spots.
  • They should be positioned out of reach.
  • A study conducted on convicted burglars suggested that it was plainly in sight. Experts recommend the installation of a mock camera to fool with the real ones in more concealed locations.
  • Nabbing an intruder is important. Your alert system should be silent when transmitted to your smartphone. An external loud clanging will only alert the perp into fleeing.
  • Keep the system armed 24/7
  • Keep camera lenses clean.
  • Where feasible, mount them indoors.


1. What are the costs involved in installing security cameras?

A high-end system can set you back by $3500, which is monitored by professional security firms. A DIY is in the region of $1500, the cost of cameras inclusive.

2. Which are the ideal locations for placing security cameras?

Ideally, all entrances should be covered including low-level window access. Remember, they may be positioned indoors and pointing out. Avoid placing it such that the guy next door doesn’t accuse you of snooping.

3. How do I go about powering my wireless security camera?

Wire-free security cameras just need batteries. If it’s a wireless security camera,you’ll need to plug it into a power source. PoE security cameras just require that the router has access to the ethernet cable.

Packaging It Together

Now that you know how to install home security cameras, go ahead and transform your house into Fort Knox. The safety of your family takes precedence at any cost. One last word of advice, the code number is sacrosanct, so don’t go sharing it around or make it easy to guess. Now you can put your mind at ease on this front.
