Security Project Planning Checklist for NZ Installers and Integrators

A successful security installation starts well before the first camera, reader, intercom or cable is installed. For New Zealand security installers and integrators, the planning stage is where system capacity, cable routes, network requirements, power budgets, recording retention and future expansion should be resolved.

A structured security project planning checklist helps reduce specification changes, undersized equipment and commissioning problems. Essential Security Supplies has also developed a range of Online Tools to help installers estimate common project requirements including CCTV storage, camera coverage, low-voltage power, PoE capacity, cable length and backup runtime.

The calculators are planning aids rather than substitutes for manufacturer specifications, site surveys or engineering requirements. Use them to test assumptions and prepare a design, then confirm the final equipment selection against the relevant product documentation and actual site conditions.

1. Define the Security Requirement Before Selecting Hardware

Start with the outcome the client expects rather than a list of products. Two sites with the same number of cameras or doors can have very different requirements.

Document the areas being protected, the risks being addressed and what the system is expected to achieve. For CCTV, determine whether each camera is intended for general observation, identification, entrances, vehicle monitoring, perimeter protection or another defined purpose. For access control, identify every controlled opening and how different users should move through the site.

The initial project brief should establish:

• Site type and operating hours.
• Areas, entrances and assets requiring protection.
• CCTV coverage objectives.
• Number and type of controlled doors or gates.
• Intercom and visitor-management requirements.
• Alarm or monitoring requirements.
• Remote-access requirements.
• Required recording retention.
• Network and IT restrictions.
• Backup-power expectations.
• Potential future expansion.
• Who will administer and maintain the finished system.

This gives the installer a design basis that can be checked throughout the project instead of selecting hardware first and trying to make it fit later.

2. Complete a Proper Site Survey

A site plan cannot reveal every installation issue. Where practical, survey the site before finalising the equipment schedule.

For surveillance projects, check proposed camera positions, mounting heights, likely fields of view, lighting conditions, potential backlighting, obstructions and cable routes. Consider how vegetation, parked vehicles, signage, shelving or future building work could affect the view.

For access control and intercom projects, inspect the physical door or gate as well as the electronic requirements. Record the door construction, frame, handing, existing locking hardware, egress requirements, cable path, power location and space available for controllers or power supplies.

Also identify equipment-room locations, network cabinets, available rack space, environmental conditions and suitable locations for NVRs, switches, controllers and UPS equipment.

Photographs and marked-up plans taken during the survey can make quoting, installation and later commissioning considerably easier.

An entry panel such as the BPT LITHOS LVC01 video entry panel illustrates why the entrance position, compatible indoor stations and cable route belong in the site survey. Check the exact system's installation instructions before specifying cable, power supplies or expansion components.

3. Calculate Camera Coverage Before Finalising CCTV

Camera quantity should be based on the required views rather than a simple cameras-per-building formula.

For each position, consider the mounting location, target area, lens or focal length, resolution and the level of detail required. A wide view may provide excellent general awareness while producing insufficient detail at a doorway, gate or distant boundary.

The camera coverage calculator in the Essential Security Supplies Online Tools can be used during planning to explore camera geometry and coverage assumptions before equipment is finalised.

Use the result as a design estimate and then confirm the selected camera's actual sensor, lens, resolution and installation requirements from its current manufacturer documentation.

This is particularly important for applications such as entrances, cash-handling locations, loading areas, car parks and vehicle access points where the useful detail at the target matters more than the headline megapixel figure.

When reviewing a camera such as the UniView IPC2128SB-ADF28KMC-I0, match the precise model to the target view and recorder compatibility. Compare suitable UniView and TVT options against the project requirements. Catalogue examples are starting points for specification, rather than a recommendation for every site.

4. Calculate CCTV Storage and Recording Retention

Do not choose surveillance hard drives simply from the number of cameras.

Storage demand is affected by camera count, configured bitrate, resolution, frame rate, compression, recording mode, scene activity and the required retention period. Continuous recording can produce a very different requirement from event-based recording.

Use the Surveillance HDD Storage Calculator in our Online Tools to estimate the storage requirement during the design stage. Enter the proposed camera groups and recording assumptions, then compare the result with the intended NVR and hard-drive configuration.

For mixed systems, calculate different camera groups separately where appropriate. A group of general-purpose fixed cameras should not automatically be assigned the same assumptions as higher-bitrate cameras covering complex or high-activity scenes.

Also confirm:

• NVR channel capacity.
• Maximum supported camera resolution and bitrate.
• Incoming recording bandwidth.
• Number of supported hard drives.
• Maximum supported drive capacity.
• Required retention target.
• Whether storage redundancy is required.
• Expansion capacity for additional cameras.

5. Build the Network and PoE Budget

For an IP security system, the network should be treated as part of the security infrastructure rather than an accessory.

List every IP camera, intercom, controller, wireless access point and other network device. Record the connection type, expected network load and power requirement where PoE is being used.

Do not select a PoE switch from port count alone. An eight-port switch may have enough physical ports for eight devices while still having insufficient total PoE capacity for the connected load.

Use the PoE planning calculator in the Essential Security Supplies Online Tools to estimate the connected power requirement and available headroom. Then verify the actual maximum power requirement of every connected device and compare the total with the selected switch's documented PoE budget.

For larger systems, also consider switch management, VLAN requirements, uplink capacity, fibre links, network segregation, remote diagnostics and spare ports. Our guide to managed versus unmanaged PoE switches for security networks provides additional guidance when deciding how much network control a project requires.

Allow sensible expansion capacity rather than designing every switch, NVR and network link to operate at its limit from day one. Browse our data and networking products once the required port counts, uplinks and power budgets have been established.

6. Check Cable Routes, Distance and Voltage Drop

Cable design should be completed before installation begins.

Record the proposed cable route to every field device and identify long runs, external routes, underground sections, inter-building links and areas exposed to electrical interference or physical damage.

For network cabling, confirm the relevant Ethernet distance limitations and the requirements of the equipment being installed. Longer runs may require an alternative network design, suitable extenders or fibre rather than simply extending copper beyond the supported specification.

For low-voltage DC equipment, conductor size, current demand and cable distance affect voltage available at the device. A power supply may provide the correct voltage at its terminals while the connected equipment receives less after cable losses.

The low-voltage power and cable-length tools on our Online Tools page can help installers test these design assumptions before selecting power supplies and cable.

Any electrical work must also comply with applicable New Zealand requirements. WorkSafe's electrical design guidance explains that the finished design must be electrically safe. Establish the appropriate design, installation and verification responsibilities for the project.

7. Plan Backup Power as a Complete System

Backup power should be based on the services that must continue operating during a power failure.

For example, keeping an NVR powered is of limited value if the PoE switch supplying its cameras has shut down. Similarly, an IP intercom may depend on the door station, network switch, controller, lock power supply and communications path.

List the complete equipment path required for each critical service and identify which components need backup.

Use the backup-runtime calculator to estimate the required capacity from the connected load and target operating time. Then verify the result against the actual UPS or battery manufacturer's specifications.

Allow for realistic operating conditions. Camera power consumption may increase when infrared illumination activates. Other equipment may have changing or start-up loads. Future expansion can also increase the demand placed on a UPS that initially appears to have substantial spare capacity.

8. Check Integration and Compatibility

Do not assume that products are fully interoperable simply because they share a network connection or a common protocol.

Check compatibility between cameras and NVRs, readers and controllers, intercom components, locking hardware, power supplies and any third-party software or building systems involved in the project.

Confirm the exact functionality required. Basic video streaming between two devices does not necessarily mean analytics, audio, events or advanced configuration will work across different platforms.

Where the project integrates CCTV, access control, intercoms, alarms or building-management systems, document which platform controls each function and how events are expected to pass between systems.

Firmware versions and licensing requirements should also be checked before commissioning, particularly on larger or staged projects.

For an IP intercom project, assess an option such as the Akuvox E12S SIP video door phone against the required calling destinations, network design, power arrangements and door-release interface. Confirm each requirement in the exact model's documentation; sharing a protocol name does not establish complete compatibility.

For access control, assess the appropriate RBH platform against the number of doors, credential requirements, event handling and expansion plan. Door hardware can come from any suitable supplier, provided the exact lock, strike, closer and exit hardware fit the door and approved operating requirements.

Include Alarm Design in the Equipment Schedule

Where an alarm system forms part of the project, evaluate suitable Risco or Elite Alarms options against the required zones, detection layout, communications path, monitoring arrangements and backup-power objective. If wireless alarms are required, include U-Prox in the assessment. Survey wireless coverage and confirm device compatibility, battery maintenance and supervision behaviour from the selected system's documentation.

9. Allow for Expansion, Service and Fault Finding

A project should not be designed only for commissioning day.

Consider how the client might expand the system and how another technician will diagnose a fault several years later.

Where appropriate, allow capacity for additional NVR channels, PoE ports, storage, controller inputs and outputs, network bandwidth and power. Leave equipment accessible for service and clearly identify cables, network ports and power circuits.

Record device names, IP addresses, switch ports and physical locations in a consistent format. Good documentation can significantly reduce the time required to identify a failed camera, trace a cable or replace network equipment later.

10. Commission Against the Original Design

Commissioning should confirm that the finished installation meets the agreed project requirements, not simply that devices power up.

For CCTV, verify every camera view under realistic conditions, including night operation where relevant. Confirm recording, playback, timestamps, retention assumptions, event operation and remote access.

For access control, test credentials, door states, locking and unlocking, request-to-exit devices, alarms and any required fail-safe or fail-secure behaviour against the approved design and applicable requirements.

For intercom systems, test calls, audio, video where fitted, door release, network connectivity and remote destinations.

Also test backup power and document the result rather than assuming the calculated runtime will be achieved in the completed installation.

Use the Essential Security Supplies Online Tools During Project Planning

The best time to identify an undersized hard drive, overloaded PoE switch or unrealistic backup-runtime target is before equipment is ordered.

Essential Security Supplies has brought practical security planning calculators together on its Online Tools page to help New Zealand installers and integrators work through common design questions. The tools can assist with surveillance storage, camera coverage, low-voltage power, PoE switching, cable length and backup-time estimates.

Enter the project assumptions, review the result and use the estimate as part of the equipment-selection process. Final selections should always be checked against current manufacturer specifications, applicable requirements and actual site conditions.

Frequently Asked Questions

When should I use the security project calculators?

Use them during the design and quotation stage, before the final equipment schedule is confirmed. They are also useful when checking proposed changes to an existing system.

Can the CCTV storage calculator determine the exact hard-drive requirement?

It provides an estimate based on the assumptions entered. Actual storage consumption depends on the final camera configuration, bitrate, codec, frame rate, recording schedule and scene activity. Confirm the finished design against the recorder and camera specifications.

Should PoE switch sizing be based on the number of ports?

No. Port count is only one requirement. Check the maximum power requirement of each connected device, the switch's total PoE budget, per-port capabilities, uplink capacity and required expansion headroom.

Why calculate backup runtime before selecting a UPS?

The required UPS depends on the equipment that must remain operational and the required runtime. Defining the load and operating objective first makes it possible to investigate an appropriately sized solution.

Can Essential Security Supplies help with larger security projects?

For projects involving CCTV, access control, intercoms, data networking or related security infrastructure, contact Essential Security Supplies about product selection, technical information and project requirements. Provide the equipment schedule, plans and design requirements where available so the project can be reviewed efficiently.

Plan the Project Before Ordering the Hardware

Good security system design is a sequence: define the requirement, survey the site, calculate the loads and capacities, select compatible equipment, verify the design, install, commission and document it.

Using a repeatable checklist makes that process easier to audit and reduces the chance that storage, power, network capacity or cabling becomes an unexpected problem during installation.
