Day Guard vs Night Guard vs 24-Hour Security: Which Do You Need?
Choosing between a day guard, a night guard and 24-hour security guards is one of the most important decisions in any security plan. It shapes how protected you are, when you are exposed, and how much you spend every month. Many property owners in Kenya default to “a night guard” because that is what neighbours have, without asking whether it actually matches their risk.
This guide compares the three options side by side, explains who each one suits, and shows how technology can fill the gaps between shifts.
The three options at a glance
| Option | Hours covered | Best for | Main gap |
|---|---|---|---|
| Day guard | Usually 6am to 6pm | Offices, shops, schools, clinics, busy homes in the day | Night-time, when most burglaries happen |
| Night guard | Usually 6pm to 6am | Homes, warehouses, sites that close in the evening | Daytime visitors, deliveries and opportunistic theft |
| 24-hour security guards | Round the clock | Estates, high-value sites, businesses open late, homes with high risk | Higher cost |
When a day guard makes sense
A day guard controls who enters your premises during working hours. That matters most where there is a lot of daytime traffic: visitors, customers, contractors, deliveries and staff.
Choose a day guard if:
- Your office, shop or clinic has constant visitors during the day
- You need someone to register visitors and check deliveries
- Your home has domestic workers, contractors or deliveries arriving while you are out
- Your property is protected at night by an alarm, electric fence or other measures
A day guard alone leaves the night uncovered, so it usually works best combined with an alarm linked to a response team. See how our alarm response services cover the hours when no guard is on site.

When a night guard makes sense
Night is when most homes and many businesses are most vulnerable. Darkness hides intruders, fewer people are around to notice them, and families are asleep. That is why a night guard is the most common choice for Kenyan homes.
Choose a night guard if:
- Your home or business is quiet or empty after dark
- You have had incidents or attempted break-ins at night
- Your street or neighbourhood is poorly lit
- Goods or vehicles are kept on the property overnight
A night guard should patrol, not just sit at the gate. Ask your provider how often guards check the perimeter and how supervisors confirm they stay alert. Our post on security guard supervision explains what good night supervision looks like.
When you need 24-hour security guards
Round-the-clock guarding gives you continuous protection. There is never a moment when the gate is unattended or the perimeter unwatched. For many sites, that continuity is essential.
Choose 24-hour security guards if:
- You manage a gated estate or apartment block with residents coming and going at all hours
- You protect high-value goods, cash, fuel or medicines
- Your business operates late or in shifts
- You have had daytime and night-time incidents
- Your family’s routine means someone is arriving or leaving at all hours
- You travel often and your home is regularly empty
How 24-hour cover actually works
A single 24-hour post is covered by at least two guards on 12-hour shifts, typically changing over at 6am and 6pm. Because guards need days off and leave, a well-run post uses relief guards across the month. The changeover itself is important: the outgoing guard should brief the incoming guard and record the handover in the occurrence book.
| Time | What happens |
|---|---|
| 5:45am | Day guard arrives, reads occurrence book |
| 6:00am | Handover: keys, equipment, incidents, expected visitors |
| 6:00am to 6:00pm | Day guard controls access and deliveries |
| 5:45pm | Night guard arrives and is briefed |
| 6:00pm | Handover recorded in occurrence book |
| 6:00pm to 6:00am | Night guard controls access and patrols |
Cost comparison
The cost of each option follows the number of guards it needs.
| Option | Guards required per post | Relative monthly cost |
|---|---|---|
| Day guard | 1 plus relief | 1× |
| Night guard | 1 plus relief | About 1× |
| 24-hour security guards | 2 plus relief | About 2× |

Mixing guards and technology
You do not always need guards on every hour to be well protected. Many clients get close to 24-hour protection at a lower cost by combining one shift with technology:
- Night guard plus daytime alarm: the alarm covers the house while the family is at work, and the guard takes over at night.
- Day guard plus night alarm and CCTV: an office has a reception guard during working hours, and an alarm with CCTV monitoring covers it after hours.
- 24-hour guards plus CCTV: guards at the gate are supported by cameras covering blind spots, so fewer patrol guards are needed.
Questions to decide which option is right
Ask yourself:
- When is my property empty?
- When have past incidents happened?
- When do visitors, workers and deliveries arrive?
- What would it cost me if something happened during the hours I leave uncovered?
- Do I have an alarm, CCTV or electric fence that could cover some hours?
If the honest answers show risk at all hours, 24-hour security guards are usually worth the extra cost. If risk is concentrated at night, a night guard plus an alarm may be enough.
Examples from typical Kenyan properties
A townhouse in Lavington: the family works during the day and has a house help at home. They choose a night guard, with an alarm and panic button for daytime.
A 60-unit apartment block in Kilimani: residents come and go at all hours and deliveries arrive constantly. The block needs 24-hour security guards at the gate, with CCTV in the parking area.
A clinic in the CBD: busy during the day, closed at night. A day guard manages patients and visitors, and an alarm with response covers the night.
A hardware warehouse in Industrial Area: open from morning to evening with stock worth millions. The owner chooses round-the-clock guards on the gate plus a night patrol guard.
How we help you choose
Our manned guarding services include day guards, night guards and 24-hour security guards, with relief cover and supervision on every contract. During a free site assessment, we look at when your property is most exposed and recommend the most cost-effective mix of guards and technology. For homes, see our residential security services.
What each shift should actually do
Whichever option you choose, each guard should have a clear set of duties for their shift. Unclear duties are one of the main reasons guards become passive.
| Shift | Core duties |
|---|---|
| Day | Register visitors and contractors, check deliveries, control vehicle access, watch domestic staff movement, keep the gate area orderly |
| Night | Lock and check gates, patrol the perimeter at set times, check lights and doors, watch for suspicious activity, respond to alarms |
| Both | Keep the occurrence book, hand over properly, report faults such as broken lights or damaged fences |
For a full list, see our security guard duties checklist.
Keeping night guards alert
The biggest risk with night cover is a guard who falls asleep or leaves their post. Good providers manage this in several ways: unannounced supervisor visits between midnight and 5am, patrol checkpoints that the guard must visit and record, regular radio or phone check-ins with a control room, and realistic shift patterns so guards are not working back-to-back doubles. Ask any company you are considering how they do this, and ask to see supervision records.
Reviewing the choice over time
Your needs will change. A family that starts with a night guard may later add a day shift when they travel more, while a business that starts with round-the-clock cover may reduce it after installing CCTV and an alarm. Review your shift pattern at least once a year, and after any incident.
Frequently asked questions
Is a night guard enough for my home?
For many homes, yes, especially when combined with an alarm for daytime. If your home is often empty during the day or you have had daytime incidents, consider 24-hour security guards.
How many guards are needed for 24-hour security?
At least two guards on 12-hour shifts, plus relief guards to cover days off and leave.
Are 24-hour security guards worth the cost?
They are worth it where risk exists at all hours: estates, apartments, high-value sites and businesses that work late. For lower-risk sites, one shift plus technology may be enough.
What time do security guard shifts change?
Most shifts change at around 6am and 6pm, with a recorded handover between guards.
Can one guard cover both day and night?
No. Asking one guard to work 24 hours straight is unsafe and against good practice. Tired guards miss things, and long shifts break labour rules. Proper round-the-clock cover always uses at least two guards rotating.
Can I switch from a night guard to 24-hour cover later?
Yes. Your security company should be able to add a day shift quickly. Call 0709 004 600 to discuss your options.
