An access control site survey should happen before an estate receives a final quotation for readers, barriers, gate motors or controllers. The survey tells the installer what actually exists on the property instead of designing the system from photographs, assumptions or a short WhatsApp conversation.
For an estate, this visit should cover the gate itself, vehicle and pedestrian movement, power, internet, cable routes, drainage, safety equipment and how residents and visitors are currently admitted. What is discovered during the survey can substantially change the equipment and installation work required.
What should an access control site survey examine?
The survey should begin with how the entrance currently works.
The installer should identify:
- number of entry and exit lanes;
- vehicle gate type;
- pedestrian entrances;
- guardhouse position;
- gate width;
- available roadside space;
- resident traffic volume;
- visitor traffic;
- delivery traffic;
- existing readers or remotes;
- available power;
- internet connection;
- existing conduit;
- and any automation already installed.
The objective is not simply to find somewhere to mount a reader.
It is to understand the whole access process.
For example, an estate may say it wants RFID vehicle access, but the survey could reveal that the entry and exit lanes are so close together that reader placement needs careful planning to prevent the wrong vehicle being detected.
Another estate may want a boom barrier but have inadequate space for the proposed arm or poor drainage around the intended foundation.
CAME's installation guidance says the type of gate and electrical preparation should be established before an operator is installed. Its documentation also identifies control panels, photocells, junction boxes and mechanical gate stops among the components that need to be considered in a complete installation.
Before the survey, understanding the wider access control system in Nigeria will help the estate committee know what the installer is assessing.
How should the gate and traffic flow be measured?
Traffic flow should be observed, not guessed.
An estate entrance that appears quiet at 11 a.m. may have a completely different problem between 5 p.m. and 8 p.m.
The survey should consider:
Gate opening width
Measure the actual usable vehicle lane.
Number of lanes
Entry and exit may require different readers and controllers.
Vehicle approach
Where does a car naturally slow down?
Where does it queue?
At what point should it be identified?
Turning radius
A reader or barrier should not be placed where vehicles regularly swing into it.
Peak traffic
Estimate how many vehicles may need to pass during the busiest periods.
Pedestrian movement
Residents, domestic staff, dispatch riders and children may cross the same vehicle path.
Tailgating risk
Look at whether one authorised vehicle can easily pull another vehicle through behind it.
These observations affect decisions about long-range RFID, barriers, loop detectors and reader positioning.
If vehicle automation is part of the project, our vehicle access control guide explains the different ways resident vehicles can be identified.
Where a boom barrier is being considered, use the boom barrier buyer's guide to check arm length, duty level and safety requirements before accepting a model.
What power, internet and backup checks should be done?
Power should be investigated before equipment is specified.
The installer should identify:
- where mains power is available;
- voltage supply;
- distance from the distribution point to the gate;
- existing inverter supply;
- generator availability;
- battery backup;
- available solar equipment;
- and which devices need continuous power.
Do not assume that because the guardhouse has a socket, the gate has adequate electrical infrastructure.
The access system may need to power:
- controller;
- reader;
- barrier;
- sliding-gate motor;
- network equipment;
- intercom;
- CCTV;
- photocells;
- and other sensors.
Backup power should also be discussed during the survey rather than after installation.
Our guide on how to power gate hardware through outages explains why supporting only the motor may still leave the entrance unusable if the controller or reader loses power.
Internet connectivity needs a separate check.
Find out:
- what connection reaches the gatehouse;
- whether Wi-Fi is being relied upon;
- where the router is located;
- whether mobile data is available as a fallback;
- and which functions actually need internet access.
Where possible, normal resident access should not depend entirely on a live cloud connection.
If offline operation is important, include a gate controller that works offline in the design discussion before hardware is purchased.
How are cable routes and drainage surveyed?
Cable routes can make a major difference to installation cost.
The survey should determine where power and communication cables need to travel.
That may involve:
- crossing the vehicle lane;
- running beside drainage;
- passing under paving;
- entering the guardhouse;
- reaching readers on separate islands;
- or connecting equipment on opposite sides of the entrance.
The installer should identify existing conduit and decide whether it can genuinely be reused.
An old pipe under the road is useful only if:
- it is still open;
- it is large enough;
- its route is known;
- and it is appropriate for the required cables.
Plan separate routes where electrical and communication requirements call for them.
The access control wiring guide explains cable distance, voltage drop, conduit and documentation in more detail.
Drainage also matters.
Do not install:
- controller cabinets where water collects;
- underground joints inside permanently wet areas;
- barrier foundations that obstruct drainage;
- or equipment where runoff repeatedly strikes electrical enclosures.
Photocell positioning must also account for the environment. Current CAME photocells are specifically designed to monitor gate movement areas, with weather-resistant features and adjustable beams on some models.
The survey should determine where such safety equipment can actually be mounted before concrete work begins.
What safety issues should the survey identify?
Automation introduces moving machinery into an area used by people and vehicles.
Safety cannot be added as a final accessory.
The survey should examine where:
- vehicles stop;
- pedestrians cross;
- children may walk;
- gatemen stand;
- dispatch riders wait;
- and gate leaves or barrier arms move.
CAME identifies photocells as important safety devices for detecting obstacles in the movement area and also offers sensitive safety edges intended to prevent automated equipment from striking vehicles or people.
For automated gates near public passageways, CAME recommends photocells and notes that intensive-use gates may also benefit from sensitive edges and movement-warning lights.
The installer should therefore explain:
Where will photocells be mounted?
What happens if a car stops beneath the barrier?
How is a pedestrian protected from a moving gate?
Can the gate be released manually?
What happens during complete power failure?
Where are emergency vehicles expected to enter?
The final design should respond to the actual risks observed at that estate rather than simply copying the installer's previous project.
What should the site survey report contain?
An access control site survey should produce something the estate can use to compare quotations.
At minimum, the installer should be able to document:
Existing conditions
What gate, power, networking and security infrastructure already exists?
Measurements
Gate width, cable distances and relevant equipment locations.
Recommended access method
For example, long-range RFID for resident vehicles, visitor codes for guests and manual approval for unusual access.
Hardware proposed
Reader, controller, barrier or gate operator, safety devices and supporting equipment.
Power requirement
Normal and backup power.
Cable routes
Including where trenching or road crossing is required.
Civil work
Foundations, islands, equipment posts or repairs.
Network requirement
Local network and internet dependencies.
Safety equipment
Photocells, loops, warning lights or other appropriate protection.
Offline behaviour
What continues working when connectivity fails?
Manual fallback
What security personnel do when automation is unavailable.
Future expansion
Whether the design leaves room for another gate, camera, reader or pedestrian entrance.
This makes quotations much easier to compare.
Without a survey specification, one supplier may quote a basic motor and remote controls while another includes controllers, photocells, civil work and backup power.
Their totals will look different because they are not quoting the same job.
How should the survey connect to Kompound?
A good site survey should examine the process before recommending hardware.
That is where Kompound fits.
The installer needs to understand how the estate wants:
- residents admitted;
- visitors approved;
- vehicles registered;
- contractors handled;
- access events recorded;
- and gatemen to work during an outage.
Kompound can manage that resident and visitor workflow while the physical access-control system handles readers, controllers and gate equipment.
The survey can therefore identify what hardware is genuinely necessary to support the process.
An estate might discover that it does not need full automation immediately.
It may begin with:
- digital visitor access;
- a gateman using a gate device;
- and a structured resident record.
Later, it can add:
- vehicle RFID;
- readers;
- an offline controller;
- a boom barrier;
- or additional pedestrian access.
That is better than buying hardware first and attempting to invent the workflow around it afterwards.
Before anyone starts digging, the estate should know where the cables are going, where the power comes from, how residents will be identified, what happens when the internet fails and what protects a vehicle or person standing in the gate's path.
That is what a useful site survey is supposed to answer.
